Viniflora CH16 is a freeze-dried pure culture of Oenococcus oeni. This malolactic bacterium has been carefully selected to induce malolactic fermentation in red wine with high alcohol levels, after direct inoculation. Viniflora CH16 has been isolated from a 16% Petit shiraz wine in the Russian River area of California, USA. The bacterium's natural environment gives a good picture of its application; CH16 has been carefully selected for its outstanding ability to conduct fast malolactic fermentation in high alcohol red wine (up to 16% v/v) with a pH value above 3.4.


  • Very high fermentation speed
  • Low production of volatile acidity
  • Outstanding tolerance to high alcohol levels.
  • Excellent all round tolerance to pH, temperature and SO2
  • No production of biogenic amines


Viniflora CH16 should be added to dry wine, immediately after the alcoholic fermentation. Viniflora CH16 should always be inoculated directly into the wine. No rehydration or reactivation is required.

For more information about ML Bacteria, please see MoreWine!'s Guide to Malolactic Fermentation.

I have used CH16 in my wine in the past. It starts conversion quickly, and finishes completely.

I am making my first batch of red wine and several sources I've read advised to use this to soften acid flavors.

Made my PH Spike Like Crazy
I'm not sure about this MLB. It took my wine with a PH of 3.1 all the way up to 4 by the time it was done. I'm not entirely sure if I can blame the MLB but I wouldn't try this strain again.

Excellent ML Bacteria
This product is easy to use as it is packaged as an appropriate dose for 1 barrel (60 gallons) of wine. I have used it for three vintages now and had great results. No MLF start or completion issues. I use ActiML and rehydrate the ML bacteria before inoculation per the MoreWine recommendations. I would definitely recommend this product.

My choice every year.
I have used this Malolactic culture for at least 10 years, success every time. Fast to start and finished with 10 days usually.
