Lalvin 71B is a wine yeast for nouveau-style wines, vodka, gin, and neutral spirits. It was isolated by Pr. Maugeneta's team at the INRA (National Agricultural Research Institute) in Narbonne, France. Lalvin 71B is a very fast starting strain that produces round, smooth, more aromatic wines that mature quickly, and it owes its success to its abilities to produce amyl ester (isoamyl acetate). Lalvin 71B also softens high acid musts by partially metabolizing malic acid (20%-30%).
