AKA UCD #522. A strong fermenter with good alcohol tolerance that is
useful in producing dry, full bodied red and white wines. Will leave a
wine with intense color and excellent flavor complexity while preserving
tannin content. This yeast will produce hydrogen sulfide gas in the
presence of excess sulfur compounds and therefore should not be used to
ferment grapes that contain residual sulfur dust. Temperature range:
59-86 F. Alcohol Tolerance: 13%.
