The name says it all. BIG RED is perfect for crafting robust, complex red wines with enduring fruitiness. Depending on the grape variety, it can highlight intricate berry and spice notes.

This yeast strain excels at breaking down and extracting tannins and anthocyanins from grape skins, resulting in wines with a deep, inky colour and a tannin structure that ages well. BIG RED also enhances mouthfeel through substantial production of polysaccharides and glycerol.

It tolerates high alcohol levels, making it suitable for grapes that ripen fully on the vine, achieving smooth tannin profiles. In summary, BIG RED accentuates berry Flavors across various varietals, yields a rich colour, extracts a comprehensive range of tannins for aging, delivers wines with excellent mouthfeel, and withstands higher alcohol content.

The only requirement? BIG RED needs nutrients, so attentive feeding during fermentation is necessary. Ideally, you should know your Free Available Nitrogen levels to tailor a nutrient schedule.

Without that data or prior experience with the grapes, we recommend starting with Fermstart hydration, initial feeding with FermFed DAP-free, and a subsequent feed with regular FermFed after one-third sugar depletion.

With proper nutrition, BIG RED produces very low levels of H2S. It's the ideal strain for exceptional red wines, but not if you plan to be away during fermentation—it demands attention.

This strain honours the varietal character, making it versatile for a wide range of red grapes, especially Bordeaux varieties like Cabernet Sauvignon, Cabernet Franc, Petit Verdot, and Merlot, as well as for robust Nebbiolo and Sangiovese styles.

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 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.
