- Reaction score
Most of us know yeast convert sugars to alcohol. What exactly is going on when lactobacillus produce lactic acid?
Interesting, would this result in a drop of OG?They break down glucose molecules in to lactate (lactic acid when in solution), which releases energy. It's the same reaction that our muscles can use when there's a higher energy need than respiration can provide (i.e. not enough O2).
C6H12O6 --> 2C3H6O3 + energy
Yes and no.Interesting, would this result in a drop of OG?
My kettle soured worts tend to drop about 2-3 gravity points. This is with Lactobacillus plantarum, a "facultative" heterofermentative species, which means that it can produce alcohol/CO2 under certain conditions. But because beer wort contains a lot of sugar, it normally doesn't make alcohol/CO2, which is a mode used when sugar is scarce.Interesting, would this result in a drop of OG?
