Lalvin 71B – 5g

R2,909.00 incl. VAT

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 the tannin structure of young and fresh red wine.

Grape must be 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.

Grape variety pairing
Cabernet Franc, Gewürztraminer, Grenache, Pinot Gris, Riesling, Viognier, Zinfandel and Gamay.

Wine Styles
Red, rosé and white young, fresh and fruity wine with smooth tannin structure as well as fruit ciders.
