Yes, champagne yeast is a nutrient-dense fungus that is a rich source of B-vitamins, including thiamin, riboflavin, and niacin. These vitamins are essential for energy metabolism and nervous system health. It also contains trace minerals like selenium and chromium, which support immune function.
Champagne yeast contains approximately 325 calories and 40.4g of protein per 100g. While it is high in protein and carbohydrates (38.2g), it is typically used in very small amounts for fermentation, meaning its caloric contribution to a final beverage is minimal.
Yes, champagne yeast is naturally vegan as it is a single-celled organism (fungus) and contains no animal products. It is also generally gluten-free, though individuals with celiac disease should check for 'certified gluten-free' labels to ensure no cross-contamination occurred during processing.
Yes, it is keto-friendly. Although it contains carbohydrates, the yeast consumes the sugars in the liquid during the fermentation process to produce alcohol and carbon dioxide, resulting in a final product that is very low in residual sugar.
You can use it, but the results will differ from standard bread yeast. Champagne yeast is bred for high alcohol tolerance and a clean finish; it may produce a smaller rise and a different flavor profile, often resulting in a denser loaf with a slightly 'yeasty' or alcoholic aroma.
It is a specialized strain of Saccharomyces cerevisiae used for fermenting champagne, dry wines, hard ciders, and mead. It is preferred for its ability to ferment quickly, handle high alcohol concentrations, and produce a very dry, crisp finish.
champagne yeast is a versatile ingredient found in cuisines around the world. With 325 calories per 100g and 40.4 grams of protein, it's a nutritious addition to many dishes.

Browse recipes →To activate (rehydrate) the yeast, stir it into a small amount of warm water (100°F to 105°F) and let it sit for about 10 to 15 minutes. Once it becomes foamy or creamy, it is active and ready to be pitched into your juice or must.
Unopened packets should be stored in a cool, dry place, but the refrigerator is best for longevity. If kept in the fridge, unopened yeast can last up to two years; once opened, it should be sealed airtight and used within 3 to 6 months.
Champagne yeast is specifically selected for its high alcohol tolerance (often up to 15-18% ABV) and its ability to ferment at cooler temperatures. It also tends to settle very firmly at the bottom of the bottle (flocculation), which helps in creating the clear appearance characteristic of sparkling wines.
It is not advisable to consume active dry champagne yeast raw. Because it is a live organism, it can continue to ferment inside the digestive tract, potentially leading to significant bloating, gas, and stomach discomfort.
