When first going wine tasting you hear a lot of strange terms. When you get in deep you're bound to hear lingo to use when you're around other people who are into tasting. Everything we do has a vernacular that is somewhat unique to it. As far as wine is concerned, there is a very distinct lingo among wine ponces. If you don't have a sense of the wine lingo, you're going to feel really lost when you’re around other people who are obsessed with the stuff. Learn this lingo and the behavioral requirements so you don’t look or sound like a cork dork. Trust us, not knowing can sometimes be embarrassing.For instance, when you drink something and it leaves a taste in your mouth, you call it an aftertaste. In wine circles, there are two terms to describe what you, used to define, using one: aftertaste and finish. The aftertaste is still the taste that remains when swallowing, but the finish is defined as the residual flavors and aroma of a wine on the palate after swallowing. You might not think there's much of a difference there, but there’s enough of a difference to warrant the existence of two terms. The general rule of thumb is, the longer the aftertaste lingers in the mouth (assuming it is a pleasant taste), the finer the quality of the wine. Hence the description; the aftertaste or "finish" is the most important factor in judging a wine's character and quality. Great wines have rich, long, complex aftertastes.
