Lalvin VP41 1-Step ™
(Oenococcus oeni)
Product details
Lalvin VP41® was isolated in Italy during an extensive European Union collaboration to research natural Oenococcus oeni strains. Numerous wineries and enological institutes participated in this four-year effort to isolate, study and select malolactic bacteria with unique winemaking properties. The positive mouthfeel contribution of Lalvin VP41® stood out in tastings when compared to other ML bacteria strains. In temperatures below 16°C (61°F), Lalvin VP41® is a slow starter, but will complete fermentation. The very good implantation, high alcohol and SO2 tolerance, plus the steady fermentation kinetics of Lalvin VP41®, make it a very reliable malolactic fermentation culture to use when a significant impact on wine structure is desired.
