House Band Wines launched its 375-ml. single-serve flexible pouch for wine in the United States in March at spring and summer music festivals. The start-up brand sees this alternative wine package as a key component in its campaign to bring wine to occasions and venues where glass is banned or impractical, the company says. The first release includes California Chardonnay and Merlot in cases of 24 pouches or four-pack cartons, which have a suggested retail price of $4.99 each.
