Boathouse Beverage LLC announced that retailers in New York City, Long Island, Massachusetts, Connecticut, and Knoxville and Nashville, Tenn., will debut SpikedSeltzer in single-flavor six-packs of slim cans, a new format for the brand. “Launching the new format was in direct response to consumer demand,” co-founder Dave Holmes said in a statement. “We’ve gotten so many requests for it, and we like to keep our fans happy.” The new format also is more conducive to the active lifestyle that the brand promotes, it adds. “We want to make it easy for you to bring SpikedSeltzer to the beach, the pool, the golf course,” co-founder Nick Shields said in a statement. “It’s a light, compact six-pack-in-a-wrap; simple and convenient.”
