Getting Ready to Make Wine

We made our annual trek to Musto Wines Grape Company to get our yeast in preparation for making wine. Over the years, we did our homework and researched some of the yeasts that we were interested in using to ferment our white and red varieties. We used the Scott Laboratories Handbook and have settled on a few yeasts that we feel are the right fit for the grape varieties that we grow.

Variety	Yeast	Yeast Characteristics
Auxerrois	QA23	S. cerevisiae bayanus Alcohol tolerance 16% YAN requirements: Low Temperature range: 59 - 90 °F Fermentation speed: fast Competitive factor: Yes MLF compatibility: Very good Sensory effect: Evc Fruity (esters) Tropical (thiols) Citrus (esters and thios) Floral Spicy Aromatic whites: Chardonnay, Sauvignon Blanc
Chenin Blanc	QA23	S. cerevisiae bayanus Alcohol tolerance 16% YAN requirements: Low Temperature range: 59 - 90 °F Fermentation speed: fast Competitive factor: Yes MLF compatibility: Very good Sensory effect: Evc Fruity (esters) Tropical (thiols) Citrus (esters and thios) Floral Spicy Aromatic whites: Chardonnay, Sauvignon Blanc
Chardonnay	D47	S. cerevisiae cerevisiae Alcohol tolerance 15% YAN requirements: Low Temperature range: 60 - 82 °F Fermentation speed: moderate Competitive factor: Yes MLF compatibility: Very good Sensory effect: Evc, M Fruity (esters) Citrus (esters and thios) Floral Mouthfeel Aromatic whites: Chardonnay Rhône Style Whites Rosé Suitable for barrel fermentation
Cabernet Sauvignon	F15	S. cerevisiae cerevisiae Alcohol tolerance 16% YAN requirements: Medium Temperature range: 68 - 89.6 °F Fermentation speed: moderate F15 is for the production of fruity, well-balanced red wines with good mouthfeel (high glycerol production). It is suitable for the vinification of musts with potentially high alcohol concentrations, especially Merlot, Cabernet Sauvignon and Zinfandel.
Cabernet Franc	FX10	S. cerevisiae cerevisiae Alcohol tolerance 16% YAN requirements: Low Temperature range: 68 - 95°F FX10 is for the production of elegant wine, with more volume on the palate (polysaccharides) and silky tannins.
Barbera	F83	S. cerevisiae cerevisiae Alcohol tolerance 16.5% YAN requirements: Low Temperature range: 68 - 86 °F Fermentation speed: moderate F83 has been selected for its ability to produce fruity, round, supple wines for early release on the market. Due to its short lag phase and easy implementation, ZYMAFLORE® F83 guarantees efficient and complete fermentations.
