This American Chain Restaurant Invented A One-Of-A-Kind Beer Glass - Tasting Table

"According to research conducted by Claudio Pellegrini, a professor of thermal and fluid sciences at the Federal University of São João del-Rei in Brazil, glasses with wide mouths and narrow bases are best for keeping beer cold. He even went so far as to figure out a formula for the ideal beer glass. The design of the Brewtus can therefore be said to have some mathematical justification."

"Beer fans who wish to drink from a scientifically optimal vessel outside of Applebee's could go for a similarly shaped glass, like the tulip or Pilsner. A Pilsner is, as the name suggests, usually intended for Pilsner lager, while the tulip is commonly used to serve Indian Pale Ales (IPAs) and Belgian-style ales. Unsurprisingly, serious beer connoisseurs have strong opinions about beer glassware - the almost ubiquitous shaker pint glass, for example,"

Applebee's signature 20-ounce Brewtus glass, introduced in 1992, features a wide mouth, narrow base and thick bottom with the Applebee's logo. The design is claimed to keep beer colder and more flavorful. Research by Claudio Pellegrini at the Federal University of São João del-Rei finds that glasses with wide mouths and narrow bases best preserve cold temperature, and he developed a formula for an ideal beer glass, giving mathematical justification to the Brewtus shape. Similar-shaped alternatives include tulip and Pilsner glasses for different beer styles. Collectors can often find Brewtus glasses second-hand online.
