If you are looking into getting into bartending, or just planning on having a party, it is important to know the difference between the various types of shot glasses. Shot glasses come in all shapes, colors, sizes and materials. Most common shot glasses fit into four type categories.
Standard Shot Glass
The standard shot glass is a little over 2 inches tall and 1 1/2 inches in diameter at the base. It holds about 1.5 oz. of alcohol. Quality shot glasses are made with thicker glass than typical glassware. They are made this way because it is tradition when taking a shot to throw the contents back quickly, then slam the glass down onto the table. The glass needs to be thicker otherwise it could break.
Smaller Shot Glasses
A pony shot is a shorter or smaller version of a shot glass. It only holds about 1 oz. of liquor. A "cheater glass" refers to a shot glass that appears to be the same size as a normal shot glass, but the glass is thicker than usual, so less liquid fits into the shot.
Fluted Or Molded Glasses
Fluted and molded shot glasses are about the same size as a typical shot glass, but they have a different design. Fluted glasses have small ridges that run along the bottom of the glass and leave a crystal ring on the table when they are set down. Molded glasses are similar in that the bottom of the glass usually has some sort of design crafted into it. The upper half of the glass might have a company name engraved into it. More sophisticated brands of shot glasses tend to conform to this design.
A "shooter" is a type of shot that contains alcohol as well as a mixer. These types of shots are typically taken in longer, cylindrical shot glasses. Cylindrical shot glasses are narrow and the narrowest sometimes resemble a test tube. Flared shot glasses are about 3 inches in height and the mouth is wider than the base. Similarly, tonic shots come in a glass that looks like a miniature version of a real tonic glass, with a wide mouth that slowly gets narrower. It is not recommended to slam taller shot glasses because they are usually made out of thinner glass.
