What Company Makes Costco's Kirkland Boxed Wine?
BY NIKITA EPHANOV
The exact origin of Costco's Kirkland Signature boxed wines is undisclosed, but being labeled as Californian, consumers speculate E&J Gallo Winery to be the original manufacturer.
A federally released database by the Alcohol and Tobacco Tax and Trade Bureau also shows that the boxed wines are interlinked with the wine giant, E&J Gallo Winery.
This detail doesn't definitively apply to the boxed wines, so it's hardly a giveaway of the origin. Regardless, their decent flavor and reasonable price make them worth buying.
