MBR PN4® was isolated from a spontaneous malolactic fermentation in a Pinot Noir by the Institute of San Michele in the Trentino region of Italy.
This strain has been known to perform under difficult conditions such as low pH (3.0-3.1) and high alcohol (up to 16% v/v).
Temperature tolerant to 14°C(57°F) and tolerant to total SO2 levels up to 60 ppm. Known for its fast fermentation kinetics.
Especially suitable for spicy and structured Pinot Noir wines.
