O. oeni adapted to high SO₂ and high alcohol; enhances complexity and mouthfeel

  • The 1-Step® VP41 (same strain as Lalvin MBR VP41) starter kit combines a highly effective malolactic starter culture with an activator to induce malolactic fermentation in an 18-24 hour build-up procedure.
  • Known strain that has proven effective at high alcohol levels (up to 15.5% v/v), pH above 3.2 and total SO2 up to 50-60 ppm.
