Hoff-Stevens Kegs are an American style of keg design. Hoff-Stevens kegs were considered the height of technology in the 1950s and 1960s. These kegs were cleaned and filled on their sides through a hole that was sealed by a wooden bung. The keg is recognized by two different-size holes on the top surrounded by male thread where the short female coupler attached to the keg. Skill was required to thread down the coupler swiftly enough to avoid squirting out beer.
The previous keg styles connected the coupler to the keg top with a quarter turn. Next the long tap would be driven with a mallet through the keg top fitting, forcing a small wooden plug into the keg, and then slid down to the bottom of the beer. Beer would invariably squirt out in this process. Most of these kegs were later converted to Hoff-Stevens.
The similar Peerless keg style also was top-tapped with a two-probe device; however, in these kegs the gas and beer lines were the same diameter and the coupler attached to the keg with a pair of hooks. Olympia Brewing Company was one of the few breweries using Peerless.
Pabst, Schlitz, and Miller breweries used Hoff-Stevens kegs. In 2008, Straub Brewery of Pennsylvania was the last long-standing brewery in the United States to discontinue their use. Production of Hoff-Stevens kegs ended by 1980 because the revolutionary Sankey design became universally accepted as a far superior technology. Fledgling microbreweries that could not afford Sankey kegs and filling equipment survived Hoff-Stevens and Golden Gate kegs, which were now inexpensive. Some small breweries continue to use Hoff-Stevens kegs to this day, but they are becoming rare.
