Wyeast Laboratories, Inc. Malo-lactic Cultures are designed for direct inoculation of 6 gallons of wine.
Malo-lactic Culture packages contain a live liquid suspension of Oenococcus oenii grown in a sterile organic juice based nutrient medium. Malic acid reduction will balance and soften wine while enhancing flavor and aroma characteristics including vanilla and buttery notes. 4007 Blend (blend of ER1A and EY2d cultures) will provide rapid and complete malic acid reduction in wine over a broad spectrum of conditions. ER1A, an excellent choice for red wines, has been isolated for it’s tolerance to low pH coditions. Ey2D has been selected for it tolerance to low cellar temperatures. Malo-lactic conversion is generally completed within 1-3 months.
The Malo-lactic Culture packages contain 125 ml of slurry.This provides the inoculation rate recommended by and for professional vintners for 6 gallons of wine. These cultures will convert malic acid to lactic acid over a broad temperature range (55-75°F). The Malo-lactic cultures will also perform over a broad spectrum of pH conditions. Inoculate wine that has completed or nearly completed alcoholic fermentation. Free SO2 levels should be less than 15 ppm.
Liquid Yeast Shipping Policy
It's hot down south, so all liquid yeast orders are shipped with an insulated pouch and two free ice packs. Liquid yeast is shipped to minimize transit time. If you order liquid yeast late in the week with a shipping method that would span the weekend we will hold your order to ship Monday. We recommend a 1 or 2 day shipping time on all liquid yeast orders. USPS Priority Mail is 2 day shipping to most of the Continental US. Liquid yeast is guaranteed viable if it spends no more than 2 days in shipping.
Liquid Yeast Warranty
As long as Liquid Yeast spends a maximum of two days in transit it is guaranteed viable and warrantied. If you receive warrantied yeast from us that does not ferment simply e-mail firstname.lastname@example.org to receive a replacement pack or refund. Please include the batch code, manufacturer date, your original gravity reading and a second gravity reading taken at least three days after pitching. A lack of swelling in your activator pack does not indicate non-viable yeast. More information on liquid yeast and frequently asked questions can be found on Wyeast's Website.
