Also called Epernay II. Produces fine white wines with fruity/estery aromas. A steady, yet moderate to slow fermenter, it is easy to stop fermentation in cases where residual sugar is desired. Recommended for fruit wines, ciders and meads as well. Ferments from 50 to 80 degrees.
Formerly known as Epernay 2, this is another slow fermenting, very low foaming and low flocculating yeast tolerant of low temperatures. It tends to bring out floral and fruity qualities in wines and can be useful in both grape--especially fruity German style whites--and non-grape wines--such as peach or raspberry--where a bouquet is especially desired. This yeast will not push alcohol production over 13% in a cool fermentation but has a range of 12-14%.
A strain of Saccharomyces cerevisiae, has been derived from a selection of the Geisenheim Institute in Germany. It is a relatively slow fermenter, identical to Geisenheim Epernay, but producing less foam. This yeast requires nutrient addition for most chardonnay fermentations. Côte des Blancs produces fine, fruity aromas and may be controlled by lowering temperature to finish with some residual sugar. It is recommended for reds, whites, sparkling cuvées and non-grape fruit wines (especially apple, it is reported). Ferments best between 17°C-30°C (64°-86°F). Sensitive below 13°C (55°F).
*Cote des Blancs is suitable only for the base cuvee for sparkling wine, and should not be used for secondary fermentation.
