acetic acid bacteria in wine
How can Acetobacter be prevented from growing in wine?
The growth of Acetobacter in wine can be suppressed through effective sanitation, by complete exclusion of air from wine in storage, and by the use of moderate amounts of sulfur dioxide in the wine as a preservative. Vinegar is produced when acetic acid bacteria act on alcoholic beverages such as wine.
What is acetic acid bacteria in red wine?
Acetic acid bacteria spoilage of bottled red wine -- a review Acetic acid bacteria (AAB) are ubiquitous organisms that are well adapted to sugar and ethanol rich environments. This family of Gram-positive bacteria are well known for their ability to produce acetic acid, the main constituent in vinegar.
What is acetic acid bacteria?
Acetic acid bacteria (AAB) are ubiquitous organisms that are well adapted to sugar and ethanol rich environments. This family of Gram-positive bacteria are well known for their ability to produce acetic acid, the main constituent in vinegar. The oxidation of ethanol through acetaldehyde to acetic acid is well understood and characterised.
How does acetic acid affect the quality of wine vinegar?
The acetic acid bacteria species determine the quality of vinegar, although the final quality is a combined result of technological process, wood contact, and aging. This discussion centers on wine vinegar and evaluates the effects of these different processes on its chemical and sensory properties. 1. Introduction
