Alkoormeilla

Alkoormeilla is a term used to describe a specific type of fungal growth that appears on alcoholic beverages, particularly wine and beer, during storage. It is not a single species but rather a general descriptor for various microorganisms, primarily yeasts and bacteria, that can proliferate in the presence of alcohol and other fermentable sugars. These microorganisms are often introduced through contaminated equipment, airborne spores, or inadequate sanitation practices during production and bottling.

The appearance of alkoormeilla can vary. It might manifest as a film on the surface of the liquid, a cloudy sediment at the bottom, or even visible strands or mats. The specific look depends on the type of microorganism present and the conditions of the beverage. While some alkoormeilla might be harmless and simply affect the aesthetic quality of the drink, others can produce off-flavors and aromas, rendering the beverage undrinkable. Common off-flavors associated with alkoormeilla include vinegary notes, medicinal tastes, or unpleasant yeasty smells.

Prevention of alkoormeilla is a critical aspect of beverage production. Strict hygiene protocols, including thorough cleaning and sterilization of all equipment, are essential. Controlling the temperature and oxygen levels during storage can also inhibit the growth of unwanted microorganisms. For consumers, proper storage of alcoholic beverages, such as keeping wine bottles on their side to keep the cork moist and prevent air ingress, can help maintain quality.
