The acid contained in vinegar, usually 3 to 6 percent, is the main volatile fatty acid in alcoholic beverages. You’ll find an appropriate amount in sour-style beers. You’ll taste an inappropriate amount in beers that have been exposed to contamination during the brewing process or in a pub’s tap lines.
Term referring to sour, tangy, or tart flavors derived from organic gases.
Additives are a fact of life — if in fact your life includes beer, which we believe no good adult life should be without. Unfortunately, the word has taken on a nasty connotation over the years (thanks a lot, aspartame), so some shudder at the thought. But in truth, if it weren’t for additives, you wouldn’t have an iota of the variety of beer available today. Fact: You can even find additives in beers brewed according to the German Purity Law — aka Reinheitsgebot — which limits beers to four ingredients: barley, hops, water, and yeast. Microbrewers tend to use fewer additives than megabrewers, but you’ll commonly find additives that enhance chemical or flavor stability, regulate color or taste, or simply stabilize foam.
Modern brewing practices indicate that oxygen should be added directly to the wort after it had been cooled, helping to ensure healthy yeast, better attenuation, better (and faster) fermentations and, no surprise, a better-tasting beer.
Aging is the deliberate brewing or distilling activity where a freshly brewed beverage is matured over a period as short as a week or several months. It is also the common impetus inspiring 9-to-5ers to quit their day jobs and devote themselves to brewing full-time.
alcoholic strength (ABV)
Alcoholic strength is created by the fermentable sugars in the beer wort and the extent to which those sugars are fermented by the yeast. The average (though not the allowable limit) of beer’s alcohol strength is between 4.8 percent and 5.2 percent alcohol by volume (ABV).
