Lalvin 71B Saccharomyces cerevisiae
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.
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.
Selected in Narbonne at the Institute national de recherche en agriculture (INRA) by J. Maugenet. The selection was designed to isolate yeasts that would produce a fruity yet fresh character in wine that would live long after fermentation.
Oenological properties and applications
The 71B strain is a rapid starter with a constant and complete fermentation between 15° and 30°C (59° and 86°F) that has the ability to metabolize high amounts (20% to 40%) of malic acid. In addition to producing rounder, smoother, more aromatic wines that tend to mature quickly, it does not extract a great deal of phenols from the must so the maturation time is further decreased.
The 71B is used primarily by professional winemakers for young wines such as vin nouveau and has been found to be very suitable for blush and residual sugar whites. For grapes in regions naturally high in acid, the partial metabolism of malic acid helps soften the wine. The 71B also has the ability to produce significant esters and higher alcohols, making it an excellent choice for fermenting concentrates.
An excellent choice for blush & residual sugar whites, nouveau & young red wines. Also a good choice for late harvest wines.
