Acid fall

Term for an unwanted acid degradation by bacteria of the genus Pediococcus and Lactobacillus, which are responsible for the degradation of malic acid in wine. This wine defect occurs as a result of uncontrolled malolactic fermentation or excessive malolactic fermentation due to improper procedures. Red wines are particularly susceptible to this. A drop in acidity is manifested by strong foam formation (due to increased carbonic acid), turbidity and possibly also by a rancid smell with sauerkraut and yoghurt tones similar to lactic acidosis. As with lactic acidosis, it is controlled by cooling and sulphurising the grape must and mash.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
