4007 Malolactic Blend

Oenococcus oeni culture blend (ER1A & Ey2d) - Wyeast Laboratories exclusive blend of Oenococcus oeni, provides rapid and complete malic acid to lactic acid conversion. Reducing the malic acid will balance and soften wine while enhancing flavor and aroma characteristics such as vanilla and buttery notes. Our blend of fresh liquid cultures performs well at a pH of 2.9 or greater and at cellar temperatures as low as 55°F (13°C). Free SO2 levels should be less than 15ppm. This package is designed to directly inoculate up to 6 gallons of wine or must that has completed or nearly completed alcoholic fermentation.

Note: Availability of this item is seasonal.

We ship all liquid yeast with an ice pack and insulated bubble envelope. Beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
