ML01 converts malic acid into lactic acid, a metabolically simple process that eliminates undesirable compounds in wine called biogenic amines -- compounds that are known to be a major cause of headaches and allergic reactions in many consumers of red wine, and of certain varieties of white wine. To call this yeast a surefire cure for a hangover would be extreme: everyone knows that's the job of a greasy burger. But there's every reason to assume that its preventive potential is real.Whether ML01 sounds like the bees knees or a terrible frankenfood, there's no way to know which wineries are using it because wineries fall under the same laws as farms and don't have to disclose GM crops. The only definite way to avoid it is to buy wine that's certified organic.

Wine-O, I'll admit to not knowing the science behind wine that much which is why I used a direct quote from the Atlantic for that part of the article. That's what it said make the ML01 different and so that's what I put.
This is a misleading article. The process of converting malic acid into lactic acid is a common occurrence in wine production, commonly referred to as "Malo" or simply "ML". This process occurs with natural wine produced with ambient (or natural) yeasts as well as wines with manufactured yeasts. There is no need for a "special" yeast to convert these acids. This is something done all the time in wine, based on the winemakers tastes, for this does affect the texture and flavor of the wine. And yes, while it would be hard to find a winery advertising which yeasts they use, they are often willing to tell you if they put their wine through "ML" or "malo"; and it is quite likely your favorite wine steward or sommelier (if their worth their salt) will know if the wine has been through malo-lactic fermentation.
Lastly, it should be known that almost all red wine, virtually all, goes through Malo-lactic fermentation. You'd be hard pressed to find any that hasn't, and if you did you probably wouldn't drink it again.
So, if you get headaches from red wine, it probably isn't the ML that will save you.
