The Blind Blind Tasting Glass was designed for wine drinkers who don't want to form pre-conceived judgments prior to tasting, who want to taste fully blind. Given that humans' first sense in judging wine is sight (in fact, blind-folded tasters have not infrequently confused red and white wines), this glass removes all visual cues.Beyond colour, the Blind Blind glass precludes immediately judging, for example, a pale-red Barolo as thin, or a deep purple pinot noir as rich. It is indeed the world's first double-blind glass.
