Know your vinegar
The term “vinegar” comes from the French vin aigre, or sour wine. It is also used to describe other soured, alcohol-based liquids, such as those made from cider, malt or rice wine. Souring is a natural process that occurs when a liquid containing less than 18 percent alcohol is exposed to the air.
On its most basic level, cheese is simply preserved milk. To “preserve the milk,” one must lower the water activity, thereby controlling the bacteria that cause spoilage. Ironically, cheese makers achieve this process with other non-harmful beneficial bacteria. The same effect is also achieved by using acid.
