The Bacchus is a white wine grape created by viticulturalistPeter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1933. 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 and can grow where Riesling, for example, does not ripen reliably. It ripens early, about the same time as Müller-Thurgau, and has a high productivity similar to 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 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 increasingly grown in several vineyards in England. The colder climate in England means that grapes retain a higher acidity and yields are lower. 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. In 2006 there were of Bacchus left in Germany, 2.1% of the total vineyard surface.
