Malolactic Cultures for Commercial Winemakers
WHEN FERMENTATION IS YOUR LIVELIHOOD, ONLY THE BEST WILL DO.
That's why Wyeast has been the choice of professional winemakers for over 30 years. Our malolactic cultures will provide rapid and complete malic acid reduction in high acid wines. Malic acid reduction will balance and soften wine while enhancing flavor and aroma characteristics including vanilla and buttery notes. Malolactic conversion is generally completed within 1-3 months. Er1A is an excellent choice for red wines, it was isolated for it tolerance to low pH conditions. Ey2d is suggested for white wines, it has been selected for it tolerance to low cellar temperatures. 4007 Blend will cover a broad range of temperatures and pH conditions.
