Lalvin 71B

Lalvin 71B® was isolated by the INRA (National Agricultural Research Institute) in Narbonne, France. Lalvin 71B® is known for making blush and semi-sweet wines with a tropical fruit character. Long-lived aromas are due to its production of relatively stable esters and higher alcohols. Lalvin 71B® also softens high acid musts by partially metabolizing malic acid.
