Collins & Coupe at 2876 El Cajon Blvd #100 is a women-owned and LGBTQ-owned bartending supply shop that has stocked craft cocktail tools and vintage barware since November 2017. Home bartenders building cocktail menus around artisan spirits pair purchases here with ingredient research at Botanica Art & Cocktail Bar, which draws from a similar craft-focused approach four blocks away on University Ave. Inventory spans shakers, mixing glasses, bitters, syrups, tonics, ice molds, cocktail books, tiki mugs, and an entire wall of curated vintage glassware. Hosts assembling charcuterie-and-cocktail pairings for home events can source artisan cheeses and cured meats at Venissimo Cheese - North Park on University Ave. The shop runs hands-on cocktail-making classes covering technique, recipe development, and home bar design for groups ranging from date-night pairs to full corporate team-building events.
