Product details

ALPHA™ was selected by the Institut Francais de la vigne et du vin (IFV), France, from spontaneous malolactic fermentations showing excellent fermentation activity and sensory contribution. Organoleptically the strain ALPHA™ enhances velvet red fruits, roundness and complexity in red wines and respects varietal aromas in white wines. This strain has a tendency to reduce green and vegetative flavours. High in permease activity hence highly recommended for Merlots, which tend to be troublesome variety to complete MLF.
