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.

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.

Very good
Great! Had to do a late MLF almost a year after the primary. This took right off and finished quick. Love it

Excellent bacteria culture
Ordered and quickly received the culture for my wine fermentation. So far, it has been easy to use from initial prep to inoculation. It has worked as advertised and really help improve our wine making process.

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.
