Perfect for everyday use, the four tequilla glasses in this set are part of the moderately priced Ouverture series offered by world-renowned German wineglass maker Riedel Crystal Being lead-free, they're not crystal like Riedel's premium glasses but are machine blown of potash glass and are dishwasher-safe. Their thin rims are cut and polished to Riedel's exacting standards, so wine flows easily onto the tongue. Each glass holds 6-3/120mls and stands 8-0.6cm high. This elegant slender glass has a tall stem, meant to lift fine Tequila to the level it deserves, to accord it the appreciation and respect of which it is worthy, Though glasses shaped and sized for different types of wine seem commonplace today, when Riedel introduced this idea in 1961, it was revolutionary. Since then Riedel has continued fine-tuning glasses to bring out the best characteristics in wines and spirits. Varying bowls' shapes and sizes affects the position of the head when sipping and where wine first contacts the tongue's various taste zones. The set of four glasses makes an excellent gift.
