The European beech ''[[Fagus sylvatica]]'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent [[firewood]]. Slats of washed beech wood are spread around the bottom of fermentation tanks for [[Budweiser]] beer. Beech logs are burned to dry the [[malt]] used in some German [[smoked beer]]s. Beech is also used to smoke [[Westphalian ham]], [[andouille]] sausage, and some cheeses.

Beeches are [[monoecious]], bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating [[catkin]]s. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small [[bur]]rs that drop from the tree in autumn. They are small, roughly triangular, and edible, with a bitter, astringent, or mild and nut-like taste.


The European beech (''Fagus sylvatica'') is the most commonly cultivated, although few important differences are seen between species aside from detail elements such as [[leaf]] shape. The leaves of beech trees are entire or sparsely toothed, from {{convert|5|–|15|cm|in|0|abbr=off}} long and {{convert|4|–|10|cm|in|0|abbr=on}} broad.
Beeches are [[monoecious]], bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating [[catkin]]s. The fruit is a three-angled [[Nut (fruit)|nut]], with two in a spiny [[dehiscent]] cupule. The bark is smooth. The leaves have a central vein with side-veins parallel to each other and ending in a tooth on the thin leaf-blade. The tree is [[deciduous]], dropping its leaves in autumn.<ref name="IDS (genus)">{{cite web |title=Trees and Shrubs Online: Fagus L. |url=https://www.treesandshrubsonline.org/articles/fagus/ |publisher=[[International Dendrology Society]] |access-date=7 October 2025}}</ref>

== Taxonomy and systematics ==
== Evolution ==
The most recent classification system of the genus recognizes 14 species in two distinct subgenera, subgenus ''Englerianae'' and ''Fagus''.<ref name="Denk-2024" /> Beech species can be diagnosed by [[Phenotype|phenotypical]] and/or [[Genotype|genotypical]] traits. Species of subgenus ''Engleriana'' are found only in East Asia, and are notably distinct from species of subgenus ''Fagus'' in that these beeches are low-branching trees, often made up of several major trunks with yellowish bark and a substantially different [[Nuclear DNA|nucleome (nuclear DNA)]], especially in noncoding, highly variable gene regions such as the [[Spacer DNA|spacers]] of the nuclear-encoded [[Ribosomal DNA|ribosomal RNA genes (ribosomal DNA)]].<ref name="Cardoni-2021">{{Citation |last1=Cardoni |first1=Simone |title=5S-IGS rDNA in wind-pollinated trees (Fagus L.) encapsulates 55 million years of reticulate evolution and hybrid origins of modern species |date=2021-10-19 |url=https://www.biorxiv.org/content/10.1101/2021.02.26.433057v2 |access-date=2024-10-24 |language=en |doi=10.1111/tpj.15601|biorxiv=10.1101/2021.02.26.433057 |last2=Piredda |first2=Roberta |last3=Denk |first3=Thomas |last4=Grimm |first4=Guido W. |last5=Papageorgiou |first5=Aristotelis C. |last6=Schulze |first6=Ernst-Detlef |last7=Scoppola |first7=Anna |last8=Shanjani |first8=Parvin Salehi |last9=Suyama |first9=Yoshihisa|journal=The Plant Journal |volume=109 |issue=4 |pages=909–926 |pmid=34808015 |pmc=9299691 }}</ref><ref name="Denk-2005">{{Cite journal |last1=Denk |first1=Thomas |last2=Grimm |first2=Guido W. |last3=Hemleben |first3=Vera |date=June 2005 |title=Patterns of molecular and morphological differentiation in Fagus (Fagaceae): phylogenetic implications |url=https://bsapubs.onlinelibrary.wiley.com/doi/10.3732/ajb.92.6.1006 |journal=American Journal of Botany |language=en |volume=92 |issue=6 |pages=1006–1016 |doi=10.3732/ajb.92.6.1006 |pmid=21652485 |issn=0002-9122}}</ref> Further differentiating characteristics include the whitish bloom on the underside of the leaves, the visible tertiary leaf veins, and a long, smooth cupule-peduncle.

The better known subgenus ''Fagus'' beeches are high-branching with tall, stout trunks and smooth silver-gray bark. This group includes five extant species in continental and insular East Asia (''[[Fagus crenata|F. crenata]], [[Fagus longipetiolata|F. longipetiolata]], [[Fagus lucida|F. lucida]]'', and the [[Cryptic speciation|cryptic]] sister species ''[[Fagus hayatae|F. hayatae]]'' and ''[[Fagus pashanica|F. pashanica]]'')'','' two pseudo-cryptic species in [[eastern North America]] ([[Fagus grandifolia|''F.&nbsp;grandifolia'']]'', [[Fagus mexicana|F. mexicana]]''), and a [[species complex]] of at least four species (''[[Fagus caspica|F. caspica]], [[Fagus hohenackeriana|F. hohenackeriana]], [[Fagus orientalis|F. orientalis]], [[Fagus sylvatica|F. sylvatica]]'') in [[Western Eurasia]]. Their genetics are highly complex and include both species-unique [[allele]]s as well as alleles and ribosomal DNA spacers that are shared between two or more species.<ref name="Denk-2024" /> The western Eurasian species are characterized by morphological and genetical gradients.

=== Taxonomy ===
 
The most recent classification system of the genus recognizes 14 species in two distinct subgenera, subgenus ''Englerianae'' and ''Fagus''.<ref name="Denk-2024"/> Beech species can be diagnosed by [[Phenotype|phenotypical]] and/or [[Genotype|genotypical]] traits. Species of subgenus ''Engleriana'' are found only in East Asia, and are notably distinct from species of subgenus ''Fagus'' in that these beeches are low-branching trees, often made up of several major trunks with yellowish bark and a substantially different [[Nuclear DNA|nucleome (nuclear DNA)]], especially in noncoding, highly variable gene regions such as the [[Spacer DNA|spacers]] of the nuclear-encoded [[Ribosomal DNA|ribosomal RNA genes (ribosomal DNA)]].<ref name="Cardoni-2021">{{cite journal|last1=Cardoni |first1=Simone |title=5S-IGS rDNA in wind-pollinated trees (Fagus L.) encapsulates 55 million years of reticulate evolution and hybrid origins of modern species |date=2021-10-19 |url=https://www.biorxiv.org/content/10.1101/2021.02.26.433057v2 |access-date=2024-10-24 |doi=10.1111/tpj.15601|biorxiv=10.1101/2021.02.26.433057 |last2=Piredda |first2=Roberta |last3=Denk |first3=Thomas |last4=Grimm |first4=Guido W. |last5=Papageorgiou |first5=Aristotelis C. |last6=Schulze |first6=Ernst-Detlef |last7=Scoppola |first7=Anna |last8=Shanjani |first8=Parvin Salehi |last9=Suyama |first9=Yoshihisa|journal=The Plant Journal |volume=109 |issue=4 |pages=909–926 |pmid=34808015 |pmc=9299691 }}</ref><ref name="Denk-2005">{{Cite journal |last1=Denk |first1=Thomas |last2=Grimm |first2=Guido W. |last3=Hemleben |first3=Vera |date=June 2005 |title=Patterns of molecular and morphological differentiation in Fagus (Fagaceae): phylogenetic implications |url=https://bsapubs.onlinelibrary.wiley.com/doi/10.3732/ajb.92.6.1006 |journal=American Journal of Botany |language=en |volume=92 |issue=6 |pages=1006–1016 |doi=10.3732/ajb.92.6.1006 |pmid=21652485 |issn=0002-9122}}</ref> Further differentiating characteristics include the whitish bloom on the underside of the leaves, the visible tertiary leaf veins, and a long, smooth [[Calybium and cupule|cupule]]-[[Peduncle (botany)|peduncle]].

The better known subgenus ''Fagus'' beeches are high-branching with tall, stout trunks and smooth silver-grey bark. This group includes five extant species in continental and insular East Asia (''[[Fagus crenata|F. crenata]], [[Fagus longipetiolata|F. longipetiolata]], [[Fagus lucida|F. lucida]]'', and the [[Cryptic speciation|cryptic]] sister species ''[[Fagus hayatae|F. hayatae]]'' and ''[[Fagus pashanica|F. pashanica]]''), two pseudo-cryptic species in [[eastern North America]] (''[[Fagus grandifolia|F.&nbsp;grandifolia]]'', ''[[Fagus mexicana|F. mexicana]]''), and a [[species complex]] of at least four species (''[[Fagus caspica|F. caspica]]'', ''[[Fagus hohenackeriana|F. hohenackeriana]]'', ''[[Fagus orientalis|F. orientalis]]'', ''[[Fagus sylvatica|F. sylvatica]]'') in [[Western Eurasia]]. Their genetics are highly complex and include both species-unique [[allele]]s as well as alleles and ribosomal DNA spacers that are shared between two or more species.<ref name="Denk-2024"/> The western Eurasian species are characterised by morphological and genetical gradients.<ref name="Denk-2024"/>

=== Etymology ===
=== Etymology ===
The name of the tree in Latin, ''fagus'' (from whence the [[generic epithet]]), is cognate with English "beech" and of [[Indo-European language|Indo-European]] origin, and played an important role in early debates on the geographical origins of the [[Proto-Indo-Europeans|Indo-European people]], the [[beech argument]]. [[Greek language|Greek]] φηγός (figós) is from the same root, but the word was transferred to the oak tree (e.g. Iliad 16.767) as a result of the absence of beech trees in southern [[Greece]].<ref>Robert Beekes, Etymological Dictionary of Greek, Leiden and Boston 2010, pp. 1565–6</ref>

Beech is not native to Ireland; however, it was widely planted in the 18th century and can become a problem shading out the native woodland understory.

Beech is widely planted for hedging and in deciduous woodlands, and mature, regenerating stands occur throughout mainland Britain at elevations below about {{convert|650|m|ft|-2|abbr=on}}.<ref>{{cite book |first1=C.D. |last1=Preston |first2=D. |last2=Pearman |first3=T.D. |last3=Dines |title=New Atlas of the British Flora |publisher=Oxford University Press |location= |date=2002 |isbn=978-0-19-851067-3 |pages= |url=}}</ref> The tallest and longest hedge in the world (according to ''[[Guinness World Records]]'') is the [[Meikleour Beech Hedges|Meikleour Beech Hedge]] in [[Meikleour]], [[Perth and Kinross]], Scotland.
=== Habitat and distribution ===


=== Continental Europe ===
Beech requires a deep soil with good drainage and a neutral or slightly acidic soil, [[pH]] 6 to 7.5. It is vulnerable to drought as its root system is relatively shallow. It does not live in waterlogged areas, but it can grow in windy places, shade from other trees, and cold. In northern Europe it is a lowland species, while further south it is [[Montane ecosystem|montane]], growing at an altitude of up to {{convert|1800|m|ft}}.<ref name="Forest Research">{{cite web |title=Beech (BE) Fagus sylvatica (L.) |url=https://www.forestresearch.gov.uk/tools-and-resources/tree-species-database/beech-be/ |publisher=[[Forest Research]] |access-date=7 October 2025}}</ref>
''Fagus sylvatica'' is one of the most common hardwood trees in north-central Europe, in France constituting alone about 15% of all nonconifers. [[Balkans|The Balkans]] are also home to the lesser-known oriental beech (''F.&nbsp;orientalis'') and Crimean beech (''F.&nbsp;taurica'').


As a naturally growing forest tree, beech marks the important border between the European deciduous forest zone and the northern pine forest zone. This border is important for wildlife and fauna.
The [[English Lowlands beech forests]] is an [[ecoregion]] of high-canopy forest dominated by European beech in southeastern England, surviving as remnants such as the {{convert|150|sqmi|sqkm}} [[New Forest]].<ref>{{WWF ecoregion|name=English Lowlands beech forests|id=pa0421}}</ref> The species arrived in Britain after the last glaciation, and may have been restricted to basic soils in the south of England.

In [[Denmark]] and Scania at the southernmost peak of the Scandinavian peninsula, southwest of the natural [[spruce]] boundary, it is the most common forest tree.  It grows naturally in Denmark and southern [[Norway]] and Sweden up to about 57–59°N. The most northern known naturally growing (not planted) beech trees are found in a small grove north of [[Bergen]] on the west coast of Norway. Near the city of [[Larvik]] is the largest naturally occurring beech forest in Norway, [[Bøkeskogen]].

Some research suggests that early agriculture patterns supported the spread of beech in continental Europe. Research has linked the establishment of beech stands in Scandinavia and Germany with cultivation and fire disturbance, i.e. early agricultural practices. Other areas which have a long history of cultivation, [[Bulgaria]] for example, do not exhibit this pattern, so how much human activity has influenced the spread of beech trees is as yet unclear.<ref name="Bradshaw-2010">{{cite journal |last1=Bradshaw |first1=R.H.W. |first2=N. |last2=Kito and |first3=T. |last3=Giesecke |title=Factors influencing the Holocene history of Fagus |journal=Forest Ecology and Management |volume=259 |issue=11 |pages=2204–12 |date=2010 |doi=10.1016/j.foreco.2009.11.035 |bibcode=2010ForEM.259.2204B |url=}}</ref>

Nowadays, they are amongst the last pure beech forests in Europe to document the undisturbed postglacial repopulation of the species, which also includes the unbroken existence of typical animals and plants. These virgin beech forests and similar forests across 12 countries in continental Europe were inscribed on the [[World Heritage Site|UNESCO World Heritage List]] in 2007.<ref name = "unesco">{{cite web |url = https://whc.unesco.org/en/list/1133 |title = Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe |website = UNESCO World Heritage Centre |publisher = United Nations Educational, Scientific, and Cultural Organization |access-date = 13 November 2021}}</ref>

=== North America ===
[[Beech bark disease]] is a fungal infection of trees in the Eastern US, Canada, and Europe. Following damage caused by the [[scale insect]]s ''[[Xylococculus betulae]]'' and ''[[Cryptococcus fagisuga]]'', the fungi ''Neonectria faginata'' and ''[[Neonectria ditissima]]'' produce cankers each year; these may eventually girdle and kill the tree.<ref name="Cale 2017">{{cite journal |last1=Cale |first1=Jonathan A. |last2=Garrison-Johnston |first2=Mariann T. |last3=Teale |first3=Stephen A. |last4=Castello |first4=John D. |title=Beech bark disease in North America: Over a century of research revisited |journal=Forest Ecology and Management |volume=394 |date=2017 |doi=10.1016/j.foreco.2017.03.031 |doi-access=free |pages=86–103 |bibcode=2017ForEM.394...86C }}</ref>
The American beech (''Fagus grandifolia'') occurs across much of the eastern United States and southeastern Canada, with a disjunct sister species in Mexico (''F. mexicana''). It is the only extant (surviving) ''Fagus'' species in the Western Hemisphere. Before the [[Pleistocene]] Ice Age, it is believed to have spanned the entire width of the continent from the Atlantic Ocean to the Pacific but now is confined to the east of the Great Plains. ''F. grandifolia'' tolerates hotter climates than European species but is not planted much as an ornamental due to slower growth and less resistance to urban pollution. It most commonly occurs as an overstory component in the northern part of its range with sugar maple, transitioning to other forest types further south such as beech-magnolia. American beech is rarely encountered in developed areas except as a remnant of a forest that was cut down for land development.


The dead brown leaves of the American beech remain on the branches until well into the following spring, when the new buds finally push them off.
[[Beech leaf disease]] is a disease that affects beeches spread by the nematode ''[[Litylenchus crenatae mccannii]]''. The disease was discovered in Ohio in 2012.<ref>{{cite news |last=Crowley |first=Brendan |date=2020-09-28 |title=Deadly 'Beech Leaf Disease' Identified Across Connecticut and Rhode Island |work=The Connecticut Examiner |url=https://ctexaminer.com/2020/09/28/deadly-beech-leaf-disease-identified-across-connecticut-and-rhode-island/ |access-date=2020-11-15}}</ref> It has spread through the Eastern United States and Canada.<ref>{{cite web |last1=Parratt |first1=Matt |title=Common beech – Fagus sylvatica |url=https://observatree.org.uk/media/1794/hotm-july-2023-beech.pdf |publisher=[[Forest Research]] |access-date=7 October 2025 |date=July 2023}}</ref>

== Ecology ==
== Uses ==
Beech grows on a wide range of soil types, acidic or basic, provided they are not waterlogged. The tree canopy casts dense shade and thickens the ground with [[leaf litter]].
 
In North America, they can form [[Beech-maple forest|beech-maple]] [[climax community|climax]] forests by partnering with the [[sugar maple]].


The [[beech blight aphid]] (''Grylloprociphilus imbricator'') is a common pest of American beech trees. Beeches are also used as food plants by some species of [[Lepidoptera]].
=== Furniture and construction ===


Beech bark is extremely thin and scars easily. Since the beech tree has such delicate bark, carvings, such as lovers' initials and other forms of graffiti, remain because the tree is unable to heal itself.<ref>{{cite book |last1=Lawrence |first1=Gale |first2=Adelaide |last2=Tyrol |title=A Field Guide to the Familiar: Learning to Observe the Natural World |publisher=Prentice-Hall |location= |date=1984 |isbn=978-0-13-314071-2 |pages=75–76 |url=}}</ref>

Beech wood is an excellent [[firewood]], easily split and burning for many hours with bright but calm flames. Slats of beech wood are washed in caustic soda to leach out any flavour or aroma characteristics and are spread around the bottom of fermentation tanks for [[Budweiser]] beer.

Template:Use British English Template:Use dmy dates Template:Automatic taxobox Beech (genus Fagus) is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, Englerianae Denk & G.W.GrimmScript error: No such module "Check for unknown parameters". and Fagus.[1] The subgenus Englerianae is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus Fagus are native to Europe, western and eastern Asia and eastern North America.

The European beech Fagus sylvatica is the most commonly cultivated species, with several ornamental varieties, and forest trees yielding a timber used for furniture, flooring and construction, plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around the bottom of fermentation tanks for some beers. Beech logs are burned to dry the malt used in some German smoked beers. Beech is also used to smoke Westphalian ham, andouille sausage, and some cheeses.

Description

Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. The fruit is a three-angled nut, with two in a spiny dehiscent cupule. The bark is smooth. The leaves have a central vein with side-veins parallel to each other and ending in a tooth on the thin leaf-blade. The tree is deciduous, dropping its leaves in autumn.[2]

Numerous species have been named globally from the fossil record spanning from the Cretaceous to the Pleistocene.[3] Some fossil species formerly placed in Fagus have been moved to other genera, namely Alnus, Castanea, Fagopsis, Fagoxylon, Fagus-pollenites, Juglans, Nothofagaphyllites, Nothofagus, and Trigonobalanus.[3]

Fagus is the first diverging lineage in the evolution of the Fagaceae family,[4][5] which includes oaks and chestnuts.[6] The oldest fossils that can be assigned to the beech lineage are 81–82 million years old pollen from the Late Cretaceous of Wyoming, United States.[4]

The first representatives of the modern-day genus were likely already present in the Paleocene of Arctic North America (western Greenland[4]) and quickly radiated across the high latitudes of the Northern Hemisphere, with a first diversity peak in the Miocene of northeastern Asia.[7][8] The contemporary species are the product of past, repeated reticulate evolutionary processes (outbreeding, introgression, hybridization).[9] As far as studied, heterozygosity and intragenomic variation are common in beech species,[9][10][11] and their chloroplast genomes are nonspecific with the exception of the Western Eurasian and North American species.[1]

Phylogeny

A cladogram of 11 extant beech species is shown below. The subgenera Engleriana and Fagus diverged from each other in the Early Oligocene era, 32.1 to 33.4 million years ago.[12]

Taxonomy

The most recent classification system of the genus recognizes 14 species in two distinct subgenera, subgenus Englerianae and Fagus.[1] Beech species can be diagnosed by phenotypical and/or genotypical traits. Species of subgenus Engleriana are found only in East Asia, and are notably distinct from species of subgenus Fagus in that these beeches are low-branching trees, often made up of several major trunks with yellowish bark and a substantially different nucleome (nuclear DNA), especially in noncoding, highly variable gene regions such as the spacers of the nuclear-encoded ribosomal RNA genes (ribosomal DNA).[9][10] Further differentiating characteristics include the whitish bloom on the underside of the leaves, the visible tertiary leaf veins, and a long, smooth cupule-peduncle. Originally proposed but not formalized by botanist Chung-Fu Shen in 1992, this group comprised two Japanese species, F. japonica and F. okamotoi, and one Chinese species, F. engleriana.[13] While the status of F. okamotoi remains uncertain, the most recent systematic treatment based on morphological and genetic data confirmed a third species, F. multinervis, endemic to Ulleungdo, a South Korean island in the Sea of Japan.[1] The beeches of Ulleungdo have been traditionally treated as a subspecies of F. engleriana, to which they are phenotypically identical,[13][14] or as a variety of F. japonica.[15] The differ from their siblings by their unique nuclear and plastid genotypes.[1][11][9]

The better known subgenus Fagus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. This group includes five extant species in continental and insular East Asia (F. crenata, F. longipetiolata, F. lucida, and the cryptic sister species F. hayatae and F. pashanica), two pseudo-cryptic species in eastern North America (F. grandifolia, F. mexicana), and a species complex of at least four species (F. caspica, F. hohenackeriana, F. orientalis, F. sylvatica) in Western Eurasia. Their genetics are highly complex and include both species-unique alleles as well as alleles and ribosomal DNA spacers that are shared between two or more species.[1] The western Eurasian species are characterised by morphological and genetical gradients.[1]

Etymology

The name of the tree in Latin, fagus (whence the generic epithet), is cognate with English "beech" and of Indo-European origin. It played a role in early debates on the geographical origins of the Indo-European people, the beech argument. Greek φηγός (figós) is from the same root, but the word was transferred to the oak tree (e.g. Iliad 16.767) as a result of the absence of beech trees in southern Greece.[27]

The common name of "beech" is from the Anglo-Saxon boc, bece or beoce, the German buche, the Swedish box - all meaning "book" as well as beech and derived from the Sanskrit boko or letter and bokos or writings. This connection to "beech" seems to have derived from the fact that the old Runic tablets were of beech wood.[28]

Ecology

Habitat and distribution

Beech requires a deep soil with good drainage and a neutral or slightly acidic soil, pH 6 to 7.5. It is vulnerable to drought as its root system is relatively shallow. It does not live in waterlogged areas, but it can grow in windy places, shade from other trees, and cold. In northern Europe it is a lowland species, while further south it is montane, growing at an altitude of up to Template:Convert.[29]

The English Lowlands beech forests is an ecoregion of high-canopy forest dominated by European beech in southeastern England, surviving as remnants such as the Template:Convert New Forest.[30] The species arrived in Britain after the last glaciation, and may have been restricted to basic soils in the south of England. It could have been introduced by Neolithic tribes who planted the trees for their edible nuts.[31] In southeast Wales, the Cwm Clydach National Nature Reserve holds beech woodlands on the western edge of their natural range in a steep limestone gorge.[32] The primeval beech forests of the Carpathians have been dominated since the last ice age by the beech.[33] In North America, beech can form Beech-maple forest, seen by some ecologists as a climax community, by partnering with the sugar maple.[34]

Pests and diseases

The beech blight aphid, Grylloprociphilus imbricator, is a common pest of American beech trees.[35]

Beech bark disease is a fungal infection of trees in the Eastern US, Canada, and Europe. Following damage caused by the scale insects Xylococculus betulae and Cryptococcus fagisuga, the fungi Neonectria faginata and Neonectria ditissima produce cankers each year; these may eventually girdle and kill the tree.[36]

Beech leaf disease is a disease that affects beeches spread by the nematode Litylenchus crenatae mccannii. The disease was discovered in Ohio in 2012.[37] It has spread through the Eastern United States and Canada.[38]

Uses

Furniture and construction

The European beech Fagus sylvatica yields a tough timber. It weighs about 720 kg per cubic metre and is widely used for furniture construction, flooring, plywood, and household items. The timber can be used to build chalets, houses, and log cabins.[39]

Ornamental tree

The European beech, Fagus sylvatica, is widely cultivated in most regions that have a suitable climate, including North and South America, Europe, South Africa, Australia, and New Zealand.[40] Many varieties are in cultivation, including the weeping beech F. sylvatica 'Pendula', several varieties of copper or purple beech, the fern-leaved beech F. sylvatica 'Asplenifolia',[41] and the tricolour beech F. sylvatica 'Roseomarginata'.[42] The columnar Dawyck beech (F. sylvatica 'Dawyck') is named after Dawyck Botanic Garden in the Scottish Borders.[43]

The tallest beech hedge in the world, and the longest hedge in Britain, is the Meikleour Beech Hedge in Perth and Kinross, Scotland.[44]

Food and food preparation

The fruit of the beech tree is an edible nut, known as beech mast.[45][46] According to the Roman statesman Pliny the Elder in his Natural History, the fruit: "of the beech is the sweetest of all; so much so, that, according to Cornelius Alexander, the people of the city of Chios, when besieged, supported themselves wholly on mast".[47] They can also be roasted and pulverized into a coffee substitute.[48]

Slats of beech wood, its flavour removed with caustic soda, are spread inside fermentation tanks for beers such as Budweiser to prevent the yeast from piling up on the bottom and possibly spoiling the beer's flavour.[49] Beech logs are burned to dry the malt used in German smoked beers.[50] Beech is also used to smoke Westphalian ham,[51] traditional andouille (an offal sausage) from Normandy,[52] and some smoked cheeses.[53]

In antiquity, Indo-European people used beech bark as a writing material, especially in a religious context.[54] Beech wood tablets were a common writing material in Germanic societies before the development of paper. The Old English bōc[55] has the primary sense of "beech" with a secondary sense of "book".[56]

The pigment bistre was made from beech wood soot. Beech litter raking was used as a replacement for straw in animal husbandry in Switzerland in the 17th century.[57][58][59][60] Beech is one of the 38 plants whose flowers are used to prepare Bach flower remedies.[61] Beech makes an excellent firewood.[62] Some drum shells are made from beech.[63] The textile modal is a kind of rayon often made wholly from cellulose extracted from pulped beech wood.[64][65][66]

In Gallo-Roman religion, Fagus (Latin for "beech") was a god known from four inscriptions found in the Hautes-Pyrénées.[67]
