Avoiding the industry phrase loaded with cachet, Chris Lingua won't call his offerings "natural wines." He prefers similar nomenclature that gets at overlapping ideas — that very little sulfur and other additives have entered the mix, resulting in wines with room to develop groovier personalities. Lingua sources some good ones. Horizontally, they line the wall of his shipping-container nook in The Churchill, organized by price point. Offerings change daily, often considerably. He has stocked nero d'Avola and frappato blends from a progressive Sicilian vintner. Austrian zweigelt, sold in the state for the first time at his shop. Biodynamic cider from Oregon. This is the cutting edge of wine today. Locally, it lives in this tiny-but-mighty downtown shop.
