About White Labs

White Labs will also offer WLP675 Malolactic Cultures to convert malic acid to lactic acid, which in turn decreases acidity and helps to soften and/or round out some of the flavors in wine. These liquid cultures are available in vials to inoculate 6-gallons or 1-liter sizes to inoculate 60 gallons.

Retailers can expand their wine strain offerings by purchasing the Vault strains from mid-July to October.
Liquid yeast has many advantages including that there is no rehydration required, it’s ready to inoculate straight into juice. The number of strains available in liquid form is greater than dry yeast options and many would agree that liquid yeast provides a more robust flavor profile across many different varietals as well.
For professionals, Vault wine strains are available in 0.5L (nanos) and 2L PurePitch® packages. Additionally, customers still have the option to order Custom Pour packaging but during July-October, the minimum order is reduced to 500mL with a 2-14 day lead time.
