VP41 1-STEP™
(Oenococcus oeni)
Highly tolerant strain for limiting conditions & very low diacetyl production.
VP41™ was isolated from nature, in a hot region of Italy region during an extensive European Union collaboration (CRAFT). VP41 1-STEP™ is an Oenococcus oeni strain with unique performance and winemaking properties, able to achieve a complete MLF in limiting conditions. Produced with our specific 1-STEP™ process and with its fast acclimatization protocol, VP41 1-STEP™ is highly reliable and very competitive, able to have a rapid implantation and dominance in must or wine.
