Named for its creator, Dr. Hermann Müller (from the Swiss canton of Thurgau), the white Müller-Thurgau varietal is one of the most widely grown grapes in Germany. There, it's mainly used to make Liebfraumilch wines. This varietal, which excels in cooler climes, is also heavily planted in England, Hungary, New Zealand, Austria, and Switzerland. It's believed to be a hybrid of Riesling and Sylvaner, but the latest theory is that it resulted from a self-pollinated Riesling seed. The varietal generally produces high yields and results in smooth, fragrant, low-acid wines that are semi-dry and somewhat characterless.
