Reliable Malolactic Culture for Smooth, Balanced Wines

Wyeast 4007 Malolactic Blend is a culture of Oenococcus oeni designed to perform malolactic fermentation (MLF) in wine. This secondary fermentation step converts sharp malic acid into softer lactic acid, reducing acidity while enhancing flavor complexity, aroma stability, and mouthfeel. It is a trusted choice for winemakers looking to produce smooth, rounded wines with long-term stability.

This blend is commonly used in red wines, barrel-aged wines, and Chardonnay, but it is suitable for many wine styles where softer acidity and enhanced balance are desired.

How We Handle and Ship Cultures

At SoCal Brewing Supply, we store all yeast and bacterial cultures under optimal refrigerated conditions with 24-hour temperature monitoring to maintain freshness and viability. For best results when ordering online, we recommend adding an ice pack to your order.

Note: Ice packs may arrive melted, which is normal. They reduce temperature shock during shipping and protect cultures through short transit times.
