You could call Vino 100 a wine boutique or a wine bar, but you might also view it as something of a wine library. Each bottle in the collection has been scrupulously catalogued according to the Wine Barometer system. Its tag decodes the complex flavors along two scales: flavor (dry to fruity) and body (light to full to solid). Buyers apply other selection criteria, too: the company guarantees it'll stock at least 100 bottles priced at $25 or less at all times, and that all those bottles will come from artisanal, limited-production wineries. Shoppers who can't wait to taste the evidence of the system's accuracy can take a bottle over to the wine bar for a small corking fee. Vino 100 also hosts wine classes and trivia nights to slake the thirst for knowledge.
