Either one of these which can be purchased at http://www.homebrewit.com/aisle/1030 for about fifty cents will work well. * Red Star® Pasteur Champagne (Davis 595), a strain of Saccharomyces bayanus, has been derived from a pure culture slant of the Institut Pasteur in Paris. This strain has been widely used in the U.S. since 1968. It is a strong fermenter with good ethanol tolerance, and will readily ferment grape musts and fruit juices to dryness. This strain also has good tolerance to free sulfur dioxide. This strain is recommended for all white wines, some reds and for fruit juices. Although this yeast is somewhat flocculant, it is not commonly used for sparkling wine. Pasteur Champagne has been recommended, by several sources, for restarting stuck fermentations. Ferments best between 15-30 deg. C, (59-86 deg. F).
* Red Star® Côte des Blancs (Davis 750), 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).. Ferments best between 17°-30°C (64°-86°F). Sensitive below 13°C (55°F).
