On Wednesday evening, customers at the Trader Joe’s on Court Street in Cobble Hill lined up at the register with bottles of lime-green margarita mix. The $3.99 price tag has drawn attention from shoppers looking for an easy drink option as temperatures push into the 80s this week.

Staff at the store say the mix has been selling steadily since Memorial Day. One cashier reported restocking the shelf twice during a single afternoon shift. The drink base is non-alcoholic and includes lime, orange, and agave flavors, with a noticeable saltiness that some shoppers say saves a step when mixing cocktails at home.

Retailers around the city have noticed a similar trend. A manager at Key Food on Avenue A said customers frequently ask if they stock the Trader Joe’s mix. So far, the answer is no. For those seeking the product, Trader Joe’s remains the only source in the city.

As rooftop gatherings and backyard parties pick up, demand for ready-to-pour mixers is likely to remain high. Some bartenders say they expect to see more customers bringing the mix to BYOB events this summer. For now, the $3.99 option continues to move quickly off local shelves.
