Mother of vinegar, an Uncommon card

The card carries these facts from its Wikipedia article.

• It is similar to the symbiotic culture of bacteria and yeast mostly known from production of kombucha, but develops to a much lesser extent due to lesser availability of yeast, which is often no longer present in wine/cider at this stage, and a different population of bacteria.
• Mother of vinegar is often added to wine, cider, or other alcoholic liquids to produce vinegar at home, although only the bacteria is required, but historically has also been used in large scale production.
