Oenococcus oeni adapted to difficult pH, alcohol and SO2

PN 4™ was isolated from a spontaneous malolactic fermentation in a Pinot noir by the Institute of San Michele in the Trentino region of Italy and is known for its fast fermentation kinetics.

For Chardonnay, PN 4 is one of the highest diacetyl producers resulting in wines that tend to be creamy and buttery with a full, round mouthfeel. When used in sequential inoculation, more diacetyl is produced. Using PN 4 on reds leads to more structured and spicy wines. PN 4 can also increase the perception of fruitiness in reds which can diminish unripe characters.

Usage
Add directly to wine and mix thoroughly.
