Anyone out there who knows about this? I've heard vague whisperings but wonder if anyone has actually tasted any wines made with this technology, called a 'probiotic' approach to wine preservation.
The crux of their approach is to isolate phenolic compounds with antioxidant properties from a variety of plant sources and then add them to the wine. But these same compounds are also present in grape skins and seeds (which is why the current version of the technology uses grape seeds). So then, as a winemaker, you might think about controlling the extraction of these compounds during fermentation in order to optimize the stability of the wine. Which is, of course, what winemakers have been doing since the dawn of time. For an example, see here.
