In comparison with breads made quickly with cultivated yeast
, sourdough often has a mildly sour taste caused by the lactic acid that's been produced by the lactobacilli.
It contains essential B- vitamins ( B1, B2, B3, B5, B6, folic acid and B12) derived from naturally cultivated yeast
that help support energy production and meet nutritional needs brought on by stressful living.
It's important to add a cultivated yeast
which is much more controlled and gives you alcohol percentages of 12 or 13 per cent.
Joly's foundation argument is that if the grapes have been grown properly, in harmony with natural forces, there will be no need to "fix" them in the cellar with artificial interventions--no need for aromatic cultivated yeast
strains, no need for osmosis (here used in its European sense of concentrating juice by water removal), no need for micro-oxygenation.
The relationship between wild fermentations and conventional, controlled fermentations with cultivated yeast
strains is a little like the relationship between organic viticulture and conventional, agro-chemical viticulture.
Part way through fermentation, a small amount of cultivated yeast
