It's Saturday afternoon, and you've already rolled your cart past the taquito sample stand at Costco four times. You look around for liquid sustenance but see only mango salsa in small paper ramekins. It's time to head south for the weekly beer tasting at Lukas Liquor Superstore. Don't worry -- no one's going to rub hops in your face or lecture you about head size. This isn't a Sam Adams commercial or a confab for RateBeer.com geeks. Instead, a guy in a polo shirt cheerfully explains how pilsners are brewed. Then he hands you a couple of ounces of the gold stuff in a clear plastic cup. You sip. He hands you another cup. To your mutual relief, nobody utters the word diacetyl. You look around the city-block-sized store and see dozens of six-pack do-it-yourselfers and chattering oenophiles. Some look flush from their visit to Lukas' swank wine bar, which, like the Saturday beer samples, is exclusive to this Martin City-neighboring location. Crisp California vodka (Hangar One rocks, and it's cheaper here), plummy Spanish priorato, grassy lagers -- a thirsty shopper could go to Lukas every day for a year without repeating a purchase. Or you could just go every Saturday for a few joyful ounces and an hour of stunned browsing.
