Lalvin 71B has been isolated and selected by INRA Narbonne (France), for its ability to produce a high level of esters (isoamyl ester), allowing it to reinforce the aromatic profile of wines fermented from neutral varieties. Lalvin 71B has the capacity to absorb polyphenolic compounds on its cellular wall which limits tannin structure of young and fresh red wine.
Grape must inoculated with Lalvin 71B will easily go through malolactic fermentation, as 20-40% of malic acid can be metabolized by this yeast strain during primary fermentation. Lalvin 71B is the perfect choice to create young, fresh and fruity red, rosé, and white wines that are easy to drink. It is also a good choice for late harvest wines.
Temperature Range: 59–86° F
