Lalvin 71B-1122 gives wine a fruity, “fruit salad” aroma, with banana and pear notes. It’s ideal for fresh, fruity Nouveau-style wines, and it brings out more fruit character in neutral grape varieties.
It absorbs some of the polyphenols that give red wine its tannin, which makes it a good fit for soft, fruity reds made to drink young. Its low nitrogen demand and low production of H2S and SO2 also make it well suited to preservative-free wines.

How to use
- Sprinkle the yeast into 5 times its weight of clean water at 40°C (25ml for a 5g sachet).
- Leave for at least 20 minutes, stirring gently now and then to break up any clumps.
- Add to the must.
Tips: Keep the total rehydration time under 45 minutes. Make sure the must is no more than 10°C cooler than the rehydrated yeast, so the yeast isn’t cold-shocked. Always rehydrate in a clean container, and don’t rehydrate the yeast directly in the must.
