Rialto Beer Flat Top Can

Grand Union Rialto Beer Flat Top

The Rialto Beer flat top can is a 1950s private-label container produced for the supermarket trade. A standout visual feature is the prominent emblem for "Grand Union Food Markets," showcasing stylized mid-century modern supermarket architecture alongside a towering roadside pylon sign. The lower rim explicitly notes that the beverage was packed expressly for The Grand Union Company of East Paterson, New Jersey.

During the postwar era, supermarket chains expanded aggressively throughout the American suburbs and developed private-label lines to offer value-oriented alternatives to national brands. Grand Union, which established its modern corporate headquarters and flagship operations in East Paterson, used the Rialto name across multiple grocery staples, including canned goods and packaged beverages. Rialto Beer was marketed through the chain's regional store network as an affordable house lager before being phased out as retail branding strategies shifted in later decades.

Although bearing the Rialto name, the beer was contract brewed in Trenton, New Jersey, by the Metropolis Brewery of New Jersey, Inc., operating under the trade identity of Rialto Brewing Company. Located at the intersection of Lalor and Lamberton Streets, the Trenton plant had previously served as the home of the Peoples Brewing Company before being acquired and modernized after Prohibition. To maintain high production volumes amid competition from national brewing conglomerates, Metropolis relied extensively on contract canning for grocery chains like Grand Union and A&P, running house labels alongside its own signature Champale malt liquor. The Trenton facility continued production under contract arrangements until changing ownership and market consolidation brought operations to an end.

For collectors of mid-century breweriana, the Rialto can occupies an engaging intersection between regional brewing history and mid-twentieth-century retail culture. It remains widely appreciated among collectors specializing in store-brand cans and postwar commercial graphic design.
