Wyeast #4007 Malo Lactic Blend (Liquid Culture)

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.

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

Bought for wine making, work as described

Excellent packaging and care were taken by the vendor. They included critical freezer packs to keep the sensitive product cool during shipping!

The package was delivered on time and in good condition. However, this fermentation process can take several months and I do not yet know how well the product works.

The ML bacteria has issue with temps over 78. The cold packs they send only last 1 day. If your not will to spend 50 for next day shipping you’re waiting your money. My shipment was dead and no refund.

It was quite dead. Waste of Money and since you have to use it to find out of its effectiveness, You can not return it because you have nothing to return.

I added some this to a gallojn of plum wine at the end of its fermentation hoping to get the malolactic going but nothing. I then added the yeast to a warm sugar water and nothing- that it shows to be dead. Maybe because it took 8 days to get here, disappointed. I wouldn't recommend buying a liquid yeast culture through the mail.
