Clos Wine Shop is a women-owned wine bar and bottle shop on Park Blvd in University Heights, San Diego, opened by Paul and Juerie Masters at 4521 Park Blvd after careers in the New York City wine and hospitality industry. The shop's inventory focuses on low-intervention, organic, and biodynamic wines sourced from small-production estates across France, Italy, Spain, and emerging regions in South America and Eastern Europe. Every bottle is available by the glass, by the flight, or for retail purchase, and the staff runs periodic wine-education classes — marketed as Clos Classes — that pair structured tastings with producer-specific background on farming practices and fermentation techniques. Beer, cider, and kombucha round out the tap list for non-wine drinkers, and the outdoor patio catches afternoon sun on the same block where French bistro Bleu Bohème anchors the 92116 dining corridor with its own Old World wine list. The storefront sits at the corner of Park Blvd and Monroe Avenue, and Park Blvd runs straight into Balboa Park from this stretch, making the shop a natural stop before or after an afternoon in the park's museums and gardens. The shop has no kitchen — an intentional design that keeps the focus on the wine program — so guests bring in food from neighboring takeout spots. Ward Canyon Park sits a few blocks north at Park Blvd and Madison Avenue, and Diversionary Theatre — one of the oldest LGBTQ+ theaters in the country — operates on the same Park Blvd corridor. Restaurants university heights queries index to this section of the boulevard, where pie-and-beer counter Pop Pie Co. draws its own following a short walk north. The wine list rotates weekly but typically carries between 80 and 120 labels spanning Pétillant-Naturel, orange wine, skin-contact whites, and single-vineyard reds from estates producing fewer than 5,000 cases annually.
