  • Really strong and fast fermentations
  • Best strain to ferment out in touch conditions
  • One of the most popular, classic Champagne strains
  • Low nutrient requrements
The classic Champagne yeast. With a fast fermentation rate, high alcohol tolerance, and low nutritional requirment it is one of the easiest yeasts to ferment. Allows varietal character to shine through while accentuating stone fruit and citrus. Able to ferment under higher pressures. Does not ferment Malic acid so natrually produces fresh wines with crisp acidity. This makes it a classic choice for fruit wines, meads and ciders. Top choice for doing secondary fermenation in the bottle for natural carbonation. One of the most popular yeast strains in the world. Can handle lower fermentation temperatures.

Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.
