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.

I have already used CH16 last season and the result is good .So l am confident that it will give me satisfaction for the coming crushing season in which I am going to crush about 50 tons of Aglianico grapes.

do i need a ice pack?? it is a freeze dried ML
Peter Fox on Sep 24, 2019
BEST ANSWER: No ice pack necessary for shipping, IMO. When you get it, store it in the freezer until you're ready to use it. I sprinkle in into the wine at the end of primary fermentation and stir it in. Keep the temperature at 62 F or above. In about 6 weeks, MLF should be complete. You will see little bubbles coming up out of the wine during MLF.

Dry Malolactic Bacteria - Viniflora CH16
BEST ANSWER: I started a yeast fermentation in bottled, non-additive apple juice from the grocery store. After two days I added the viniflora bacteria. Within a day it was very active. At that point I added it to my second-day wine fermentation.

Dry Malolactic Bacteria - Viniflora CH16
BEST ANSWER: ACTI-ML isn't the nutrient designed to be added to the wine ... it's used during the initial hydration of the ML bacteria. The nutrient to add to the wine during ML is Opti Malo Plus.
The MoreWine manual MLF states that 2.5 grams are needed for 66 gallons, but this product is shown to be 1.5 grams and good for 66 gallons. Is this correct? If so, do I adjust the proportions of Acti-ML and Opti-Malo for 1.5 grams rather than 2.5 grams of bacteria?
Matt Sommerfeld on Sep 11, 2019
BEST ANSWER: Hello Matt, this particular strain of bacteria is made to be used at 1.5 grams per 66 gallons of wine. The Acti-Ml and Opti-Malo plus dosages will remain the same. Acti-ML is to be used at 0.84 grams per gallon of wine and Opti-Malo plus is 1 gram per gallon of wine.
Max batch size is 66 gallons. I am only making 6. Any concerns with inoculating the smaller batch with the entire packet? Asking due to the short shelf life of the bacteria once opened.
Kevin E Hart on Feb 10, 2019
BEST ANSWER: Hi Kevin - Adding the full packet should not cause any problems, it will cause the MLF to move along faster which is not a bad thing. You could store any leftovers in the freezer but it's not guaranteed to hold for a long period of time.

Worked fast
I am making Cabernet Sauvignon wine from my grapes. I had crushed out about 12 gallons, so 2 six gallon fermenters. The instructions said this would inoculate 66 gallons and I divided it between the 2 batches, along with a package of malolactic nutrient. In just a few hours it was bubbling away. Very pleased.

Too early to rate other than its fermenting. Will comment when it’s time to bottle.

Good ML action from pitch
Package arrived in sealed plastic bag. I kept in fridge for about 4 days. I pitched ML with the ML nutritions per instruction and has been a strong and consistent ML action. So far happy with result; will check chromatography soon.

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.
