Trommer's Bock Flat Top Can

Trommer's Elusive Bock Flat Top

The Trommer's Bock flat top stands as one of the most celebrated and sought-after treasures in the breweriana hobby. Produced by John F. Trommer, Inc. at their Orange, New Jersey facility, this seasonal bock can represents a pinnacle piece of mid-century East Coast brewing history.

While John F. Trommer, Inc. was originally established in Brooklyn, the company expanded operations into New Jersey after acquiring the former Orange Brewery. Although standard Trommer's ale and lager cans from the Orange facility were distributed widely, the Bock was a seasonal release packaged in far smaller quantities. Because bock was historically marketed during a narrow window in the spring, its packaging run was brief, leaving behind very few surviving examples.

The can features bold Trommer's branding alongside traditional bock styling. Graphic variations exist across production runs, featuring minor distinctions such as straight versus flared styling in the brand typography, as well as variations in instructional side panels and tax-paid statements.

In collector circles, the Trommer's Bock flat top is legendary. It rarely appears at public auctions, and when genuine examples do surface, they consistently draw widespread attention and command five-figure sale prices, securing its place as an elite centerpiece in the world of vintage can collecting.
