The result is production of lactic acid in these parts leading to stiffness or cramps. While there are a number of products from fermentation, the most common are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H 2). At the end of fermentation which can last from 4-8 weeks the total acidity of the product is 1.7-2.3%, expressed as lactic acid, with a ratio of volatile to non-volatile acid of around 1 to 4.
