Not in my opinion, but I don't drink any alcohol. I think the lacto fermenting produces very little (if any?) alcohol.
|Another study zeroed in on polyphenols such as catechin, quercetin, resveratrol and others which are found in red wine, but not white. The reason they are found in red wines but not white is that these substances are natural components of grape skins. Since red wines are fermented on the skins while white wines are not, it is the fermentation of the skins that seems critical to health promotion. This contention is supported by a study conducted by researchers from Portugal, Switzerland, Finland and Denmark. An extract from red-wine fermentation called ANOX (a trademark of IME, Switzerland) has been developed as a source of red-wine polyphenols. This extract has a significantly greater effect than either red wine or red wine powder on the inhibition of platelet aggregation in vitro and has several health promotion benefits.|

|When compared with dealcoholized wine and normalized to polyphenol dose, red wine's beneficial effects can be attributed entirely to the polyphenols. Grape juice had a significant benefit at a much lower dose of polyphenols than the wines. Grape juice was calculated to be much more effective than red wine or dealcoholized red wine at the same polyphenol dose in inhibiting atherosclerosis and improving lipids and antioxidant parameters.|
