Product details

Lalvin 31™ (MBR™) was selected by the Institut Français de la Vigne et du Vin (IFV), France, and performs well under such stressful conditions as low pH (>3.1) or low temperature (>14°C/57°F). Final color intensity depends on the duration of malolactic fermentation (MLF). By being able to carry out MLF at low temperature, Lalvin 31® gives the winemaker control to obtain wine with higher color intensity and stability; Lalvin 31™is noted for its good sensory balance in red and white wines, and for low production of biogenic amines; Lalvin 31™ benefits from the addition of a malolactic nutrient such as Opti’Malo PLUS™.
