The personalities of individual grape wines depend on everything from weather and temperature during the growing season to the type of yeast used in fermentation to the material of the kegs used to age the wine.
Malolactic fermentation is done if you are hitting a target, if you are in a diamond, where PH (acidity) must be at least 3.2, Alcohol is less than 13%, Temperature is on 16C or higher (best 18C -65F), SO2 less than 10ppm.
Oxygen can also help eliminate reduction during fermentation, but once fermentation is complete, you'll need other tools to remove reduction.
When this fermentation is complete, the picture will be a whole lot clearer, but I am very optimistic.
The process takes place in fermentation vats, into which the bacteria expel little drops of oil.
Buchner's experiments showed unequivocally that fermentation is a catalytic process caused by the action of enzymes, as had been suggested by Berzelius for all life processes, and Buchner called his extract zymase
Using genetically modified bugs for fermentation is essentially the same as using natural bacteria to produce ethanol, although the energy-intensive final process of distillation is virtually eliminated because the bugs excrete a substance that is almost pump-ready.
