Wine Prism Wine Tasting Glass Stem
An ingenuous wine-tasting device for connoisseurs and weekend enthusiasts alike. A small hole on the top of the glass stem allows air and wine to swirl and combine before tasting. Aerating the wine in this manner gives you a much more detailed examination of its various components: fruit, tannins, acidity, fermentation, and barrel influence. The Wine Prism lets you evaluate your wine tasting more precisely and consistently than by the common method of drawing in air by the "reverse whistle" technique.
