Pure Lees Longevity Plus (1kg)

Inactivated yeast blend for a very gentle fining and oxidation protection

Pure-Lees Longevity Plus™ is a proprietary blend of inactivated yeast and bentonite for use immediately after alcoholic fermentation, on wines susceptible to oxidation. Oxidation can be responsible for the loss of fruit character. Use of Pure-Lees Longevity Plus helps protect color and aromas.

To develop Pure-Lees Longevity Plus, Lallemand collaborated with INRA to research different inactivated yeast fractions and evaluate their impact on oxidation. The result is a product with high dissolved oxygen uptake capacity. In fact, it was more efficient than SO₂ at preserving color and thiols during 5-month aging trials.
