The Bacchus is a white wine grape that was created by viticulturalist Peter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1933.〔(Wein-Plus Glossar: Bacchus ), accessed on January 24, 2013〕〔(Vitis International Variety Catalogue: Bacchus Weiss ), accessed on May 26, 2008〕 He crossed a Silvaner x Riesling cross with Müller-Thurgau. Bacchus received varietal protection and was released for general cultivation in 1972.〔 Its name is taken from Roman name of the Greek wine god Dionysus. Bacchus can reach high must weights, and has no high requirement for sites it can be planted. It can therefore be used where e.g. Riesling does not ripen reliably. It ripens early, about the same time as Müller-Thurgau, and has a similar high productivity as that variety.〔 Bacchus wines can have powerful flavours and character, which have even been described as "exuberant", but only if it is allowed to ripen fully.〔 It is however low in acidity, which does not always make it very well suited for varietal wines under typical German growing conditions. Among the new breeds, it is considered to give less elegant wines than Kerner. Therefore, Bacchus is often used for blending into Müller-Thurgau, to give the latter more flavour. Within Germany, Franconia is considered as the source of some of the more successful varietal Bacchus wines.〔 Bacchus is also grown in England.〔(English Wine Producers ) (The Marketing Association of the English Wine Industry)〕 Under British growing conditions, where the colder climate means that a higher acidity is retained and where only lower yields are possible, Bacchus can give varietal wines of reasonable quality, somewhat in a Sauvignon blanc-like style.〔 German plantations peaked in the 1990 at around of which more than half were in Rheinhessen, where it was popular to use in QbA blends. Plantations have since decreased and in 2006 there were of Bacchus left in Germany or 2.1% of the total vineyard surface.〔(German Wine Institute: German Wine Statistics 2007-2008 )〕 == Synonyms == Synonyms for the Bacchus variety include Bacchus Weiss, Weisser Bacchus, Frühe Scheurebe, Geilweilerhof 33-29-133 and Gf. 33-29-133.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bacchus (grape)」の詳細全文を読む スポンサード リンク
