a/k/a Beer Tap Markers

The genesis of the current beer tap handles, shown on the wallpaper of this page, dates directly after Prohibition, to around 1933. Before prohibition, brewers either owned taverns and saloons that served only their beer, or had arrangements with tavern owners to just sell their beer, and it was normally served from kegs. Since there wasn't usually a choice of beers in a drinking establishment before Prohibition, there wasn't a need to have names on beer tap markers before Prohibition. However, after Prohibition, establishments serving beer were able to serve beer from different brewers. To identify the draft beer that was being dispensed from a keg and assure customers they were obtaining the beer they wanted, there were regulations that required what was officially known as "beer tap markers" to be used. They made it necessary to have a tap marker of a certain size and ball like shape. Consequently, they were also called "beer ball knobs." Such knobs for Bavarian Brewing are presented below.

Much more information about these knobs and markers is provided in two publications by George Baley, "Beer Tap Markers" published in 2003 and "Beer Tap Markers Vol. 2" published in 2019. (For both, please see this link.) Each provides about 2,000 photos with price guides for all tap markers covered from the early 1930s into the 1950s. In addition, to view a presentation of the beer tap markers in the Cincinnati area, including Northern Kentucky and the Bavarian Brewery, please view the video above.


The earliest beer ball knobs were made of Baekelite, also referred to as Bakelite.  This was the first plastic made from synthetic components and it was usually offered only in dark colors. It was developed by Leo Baekleand in 1907, and the name of this material is referred to after his name. It was revolutionary because it was an electrical nonconductor that was also heat resistant and well suited for electrical insulators. After some litigation was resolved, the Baekelite Corporation was formed around1920, however, some of Baeklite's patents expired in 1927. This allowed some other resins to be produced by other firms, such as Catalin Co. under the Prystal name, which provided more and brighter colors. Nevertheless, because of their similar qualities, these other resins are often associated with the name Baekelite. This material was used for the exteriors of radios and telephones by the 1930's, as well as for such diverse products as kitchenware, jewelry, toys, firearms and, of course, ball knobs. 

Bavarian Ball Knob c. 1935 - 1937.

This is thought to be the first beer tap marker, or ball knob used by Bavarian Brewing Co., possibly beginning around 1935. Since the use of Bavarian in italics, shown below, didn't appear to begin until around 1938, and the use of 'Bavarian's" and "Old Style" didn't begin until around 1946, it appears that this knob preceded the other knobs.    

Bavarian Beer Knob c. 1938 - Mid 1940s.

These ball knobs on the right were used in the late 1930s before the "Bavarian's Old Style Beer" name was used. They are very similar, except for slightly darker/lighter inserts and different colored knobs, which were made by different companies.   

Schott Select / Ale Ball  & Bavarian Knob c. 1940 - Early 1950s. 

Schott Select was for an ale named after the Schott Brothers, who acquired the brewery in early 1938. Schott Select/Ale was introduced in about 1940 and likely discontinued shortly after WWII, but may have continued into the early 1950s. The Bavarian knob was probably used around 1945 and for a short time,  just before the Old Style logo began, as shown on the knobs below.

Bavarian's Old Style Ball Knobs c. 1946 - Mid 1950s.

The knobs below display the use of the term Old Style that began in 1946.  It wasn't until this year that Bavarian's (with an apostrophe s) was also used. These knobs were used until probably the mid 1950's. The most common of the three similar "Old Style" knobs are the two on the left. The other knobs on the right with different color variations are more unusual.


Late 1940's - Mid 1950's.  Those knobs with a metallic finish became more common after WWII in the later 1940s and early 1950s. The larger knob on the far right, which dates in the early to mid 1950s, was a variety  referred to as a "Tin Can" style. ​The other metal bases to the side and above, were made by the Fox Co., in Cincinnati, OH.


Late 1950s to Mid 1960s. Beginning in the mid 1950s the Beakelite and metallic knobs were replaced by Lucite knobs. International Breweries Inc. (IBI) apparently did not use any Baekelite or Metallic knobs as shown above, but instead used these Lucite Knobs. They were larger than the other knob types and allowed for equal visibility of the beer brand on both sides of the tap knob. 






From the Early 1960s. The shape of tap handles that began to resemble current tap handles began in the early 1960's. An example of such a handle for Bavarian's Select Beer, which was made by Int'l Breweries Inc. for most of their other brands as well. 


The early ball knobs in the mid 1930s and 1940s were made by a dozen or so manufactures usually using a substance called Baekelite, or Bakelite. The medallions that were placed on a cut surface of the knobs were usually metallic.


After a couple of decades, beginning in the early 1950s, the tap marker evolved from a ball shape to a larger shape. As they became larger, a metal design developed in what was referred to as "tin can" style, because of its resemblance to one.


By the mid and late 1950s, the tap markers with clear Lucite were becoming wider and taller.  Plastic was mostly used thereafter. They became more advertising friendly allowing the beer name and an associated image to be seen on either side of the tap handle.  These knobs or tap markers began to become much taller to allow for more advertising and associated images, and are now known as "tap handles" today.  Images of these are shown on the background image.
