Description

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.

VP41 has proven effective at high alcohol levels (up to 16% v/v), pH above 3.1, total SO2 up to 60 ppm, and temperature down to 16°C(61°F).

1-Step® cultures are improved versions of an old concept. The purpose is to provide winemakers with a product that combines the economy and activity of standard strains with a degree of the convenience associated with the direct inoculation strains.

In lieu of direct inoculation or prolonged build-up, a simple 18–24 hour >acclimatization step is required using a culture of Oenococcus oeni and an activator (included in the kits). 1-Step cultures are a good choice when efficiency and cost management are essential. The 1-Step cultures can also be used to restart a stuck or sluggish MLF.

None of our commercial ML strains contain the decarboxylase enzymes known to produce biogenic amines

Prior to use please review the Rehydration Protocols for Sequenial Inoculation or for Co-Inoculation.
