Like a well-aged Brunello, Cavas Wine Tasting Room hits the (visual) palate with a complex burst of impressions. The décor lands first. Casual leather sofas rest near floor-to-ceiling windows looking out on the masses wandering happily along Española Way. Chic, tall black tables with tiny candles fill the floor, and hundreds of wine bottles, attractively lit with soft bulbs, line the walls. But just when you think you've wandered into another casual wine bar, your eyes catch... the machines. Along each wall, 70 or 80 uncorked bottles of wine nestle inside the stainless-steel contraptions with glowing red LED lights and thin spouts, like espresso makers. Not only is the ambiance lovely, but also the devices are key to Cavas's take on the winetasting experience. Here's how it works: You buy a plastic card, loaded with however much you'd like to spend, from the front desk. You swipe the card in the machines, which can dispense one-ounce samples, half-glasses, or full glasses of any bottle on display. Before you know it, you're wandering around like a kid with a charge card at the video arcade, trying one-dollar sips of cool, cheap Australian Chardonnay; nine-dollar ounces of oaky aged French Merlots; and eight-dollar half glasses of crisp Malbec. It's winetasting from the future, homes. And it goes down smooth.
