Lalvin Persy™ has a unique property in that it will not produce any SO2 during alcoholic fermentation, and also, non-perceptible amount of H2S. This makes it an ideal wine yeast for varietals such as Shiraz, Tempranillo and Pinot Noir, where it will produce wines that will fully express their varietal aromas. The fruit characters are enhanced, and the freshness and aromatic persistency optimized. Lalvin Persy™ is a good fermenter, has good tolerance to alcohol and is compatible with malolactic fermentation.
The selection of Lalvin Persy™ is the result of a collaborative study between Lallemand, Montpellier SupAgro and INRA Montpellier. This innovative selection technique for yeast has been patented:
