## Description

Malolactic culture blend isolated from western Oregon wineries. Can be added to juice any time after the onset of yeast fermentation when sulfur dioxide is less than 15 ppm. Use at temperatures greater than 55 deg F Contains a live liquid suspension of Oenococcus oenii grown in a sterile organic juice based nutrient medium.

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. Usage: The Malo-lactic Culture packages contain 125 ml of slurry. This provides the inoculation rate recommended by and for professional vintners for 5 gallons of wine. These cultures will convert malic acid to lactic acid over a broad temperature range (55-90°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. Basic instructions for the proper use of Malo-lactic packages: Shake package well, sanitize, and open. Add contents to 5 gallons of wine. Adjust to desired cellaring temperature. Monitor Malic Acid conversion monthly with paper chromatography or other methods. Best if Used by: This package is best when used within 6 months of the manufacturer's date when stored between 34-40°F (1-4°C). Older malo-lactic cultures that have been exposed to higher or lower temperatures may perform slowly.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by P***3 on January 30, 2018*

Did the job, even in our cool (low 60s) basement. I saw very fine bubbles a few days after I added it. Not sure if those fine bubbles were leftover CO2 from fermentation or if they were from the MLF bacteria, but anyway, they stopped after a week or so. I didn't monitor it to see exactly how long it took, but it was done when I checked it 2 months later.UPDATE: Have used this several times and never had it fail. It's nice because other malolactic bacteria cost a lot more because the packs are meant to treat up to 66 gallons. This is the right size (and price) for the average 6 gallon carboy. Malolactic fermentation greatly improves the acid balance and mouth feel of nearly all red wine. If you're making a red wine, chances are you'll want to do MLF and this is a good bacteria to use. Add it right after primary fermentation is complete.

### ⭐ Cooked dead
*by J***Y on August 20, 2024*

This is probably an excellent product, but mishandled as a live product. DOA

### ⭐⭐⭐⭐⭐ for wine making
