Red Star Premier Rouge Yeast | 5 Gram Sachet

Red Wine Yeast for Structure, Color, and Dark Fruit Character

Red Star Premier Rouge is a dry red wine yeast suited to bold, structured fermentations. Formerly known as Pasteur Red, it is commonly used for Cabernet Sauvignon, Cabernet Franc, Merlot, Zinfandel, Syrah, and other red wines where color extraction, mouthfeel, and varietal fruit character matter.

This strain is a good fit when you want a red wine fermentation with steady kinetics and enough structure for oak contact or aging. It can also work in dark fruit wines and meads when you want more body and red-wine style depth instead of a very neutral ferment.

Best Uses

• Cabernet Sauvignon, Cabernet Franc, Merlot, Zinfandel, and Syrah
• Full-bodied red wines and red fruit wines
• Meads or melomels where red-wine structure is desired
• Fermentations that benefit from good color and tannin extraction

Fermentation Notes

• Format: 5 g dry wine yeast sachet
• Batch size: commonly used for 1 to 6 gallons
• Alcohol tolerance: up to about 15% ABV
• Temperature range: 64-86°F
• Fermentation character: medium kinetics with strong red-wine performance
• Nutrient needs: benefits from good nutrient support, especially in fruit wine and mead

Shop Notes

Premier Rouge is best used with temperature control and a sound nutrient plan. In grape musts, it is useful for building structure and helping fruit character carry through fermentation. In mead or fruit wine, use proper nutrient additions to reduce stress and keep the profile clean.
