Iittala Glassware Dining and Entertaining Essence Red Wine - Only We reviewed many different types of glasses in order to come up with our essential, minimal glass series. What remains are four glasses that, in both form and function, are the answer to our modern needs. All Essence glasses are high-stemmed. This gives a uniquely balanced look to tables set with several glasses. The red wine glass can also be used for beer; the white wine glass doubles as a champagne flute. You can serve liqueur or schnapps in the dessert wine glass.
