Visiting wineries
Traveling to wine regions is another way of increasing skill in tasting. Many wine producers in wine regions all over the world offer tastings of their wine. Depending on the country or region, tasting at the winery may incur a small charge to allow the producer to cover costs.
It is not considered rude to spit out wine at a winery, even in the presence of the wine maker or owner. Generally, a spittoon will be provided. In some regions of the world, tasters simply spit on the floor or onto gravel surrounding barrels. It is polite to inquire about where to spit before beginning tasting.
Expectoration
Because intoxication can affect the consumer’s judgment, wine tasters generally spit the wine out after they have assessed its quality at formal tastings, where dozens of wines may be assessed. However, since wine is absorbed through the skin inside the mouth, tasting from twenty to twenty-five samplings can still produce an intoxicating effect, depending on the alcoholic content of the wine.
