Premier Blanc is the same yeast that was formerly called Pasteur Champagne. Red Stars Premier Blanc is a strong strain with a very high alcohol tolerance (up to 18% vol.). Used to avoid sluggish fermentation and to restart stuck ones with remaining residual sugars. Recommended for sparkling wines processed by traditional or Charmat methods.Great for meads, ciders, and other wines where you want a real clean and thorough fermentation. Works well for drying out high gravity beers as well.
