To continue from my last posting, which had more to do with the viticulturalist aspect of winemaking, I will now turn to the actual making of wine, which begins with the process of adding yeast to the grape juice, the basis for the wine. Mas des Dames, being an organic estate, wishes to avoid using yeasts which impart flavours, so “levures naturelles,” or natural yeasts are used. These actually come from Syrah vines from Guigal in the Rhône.

The question might be asked: why not just use natural yeasts which exist in the vineyard, but oenologist Xavier Billet explains that this at all costs is to be avoided. Some of these yeasts may be from the Saccharomyces cerevisiae family, but others (Brettanomyces, etc.) not. These are unpredictable yeasts which can rapidly turn wine into vinegar, or not. But one chooses for certainty. more>>
