'''Regent''' is a dark-skinned inter-specific [[hybrid grapes|hybrid grape]] variety, used for making wine.<ref name="OCW Regent">{{cite encyclopedia |editor=[[Jancis Robinson]] |encyclopedia=[[Oxford Companion to Wine]] |edition=Third |title=Regent |year=2006 |publisher=Oxford University Press |location=Oxford |isbn=0-19-860990-6 |pages=[https://archive.org/details/oxfordcompaniont00janc/page/565 565] |url=https://archive.org/details/oxfordcompaniont00janc/page/565 }}</ref> It has both European (''[[Vitis vinifera]]'') and American [[vine]] [[species]] in its [[Plant breeding|pedigree]] and a broad resistance against the most significant fungal diseases which affect grapes, such as [[downy mildew]].

==History==
Regent was created in 1967 by Professor Gerhardt Alleweldt at the [[Geilweilerhof Institute for Grape Breeding]] in Germany by crossing Diana, a [[Silvaner]] x [[Müller-Thurgau]] cross and thus a ''Vitis vinifera'' variety, with the interspecific hybrid [[Chambourcin]].<ref name="VIVC Regent">[http://www.vivc.de/index.php?r=passport%2Fview&id=4572 Vitis International Variety Catalogue: Regent] {{webarchive|url=https://web.archive.org/web/20120422105542/http://www.vivc.de/datasheet/dataResult.php?data=4572|date=2012-04-22}}, accessed on June 19, 2008</ref> Experimental plantings followed in 1985,<ref name="DWI Regent">[http://www.deutscheweine.de/icc/Internet-DE/nav/e80/e8060b82-fba0-6401-e76c-d7b482058468&_ic_uCon=1e0308fd-e785-7401-be59-267b48205846 German Wine Institute: Regent] {{webarchive|url=https://web.archive.org/web/20130304210212/http://www.deutscheweine.de/icc/internet-de/nav/e80/e8060b82-fba0-6401-e76c-d7b482058468%26_ic_uCon%3D1e0308fd-e785-7401-be59-267b48205846 |date=2013-03-04 }}, accessed on June 19, 2008 {{in lang|de}}</ref> varietal protection was received in 1994 and it was released for cultivation in the first German region in 1996.<ref>[http://www.bafz.de/baz2006V4/index.php?id=455 Institute of Grapevine Breeding Geilweilerhof: Regent] {{webarchive|url=https://web.archive.org/web/20070927202840/http://www.bafz.de/baz2006V4/index.php?id=455 |date=2007-09-27 }}, accessed on June 19, 2008</ref> It is at present among the most important new fungal-resistant quality grape variety world-wide, especially in [[German wine]] regions.

==Grape and grapegrowing==
Regent is a cool-weather red winegrape. Regent provides medium-sized grapes and clusters. It is a heavy bearer, and has an upright growing habit that is similar to vinifera: It can be trained to the VSP (Vertical Shoot Positioning) method from canes tied to the low fruiting wire. It is a mid to late-season ripener. In some climates (e.g., NW Oregon USA), Regent often blooms during the last week of the Spring rains (which usually cease on or about July 5), and the blooms, if wet, are highly susceptible to Botrytis, which rots the flower clusters and prevents fruit set. This is the primary "Achilles Heel" of this otherwise impressive grape; a lesser disadvantage is its late ripening schedule. This grape would do best in a cool, dry area with a long growing season. Further north in upstate Washington, the vine buds and flowers later and this issue is less observed. Without preventive steps, Regent often yields no fruit in NW Oregon if Botrytis is not managed.

==Wines==
Regent wines are colour intensive red wines with moderate acidity, can have rather much [[grape tannins|tannin]] and show aromas of cherries or blackcurrants. The wines often reach high alcohol levels since Regent tends to reach high [[must weight]]s. Some German versions are matured in [[barrique]]s.<ref name="DWI Regent"/> The grape is fairly easy to make good wine from. It has excellent skin color (perhaps so much that the color can seem overly vivid), and clean vinifera-type flavors.

==Synonyms==
Regent is also known under its breeding code Geilweilerhof 67-198-3 or Gf. 67-198-3.<ref name="VIVC Regent"/>
