As a sommelier and brewer, I can tell you that shot glasses come in various sizes, and there is no one-size-fits-all answer to how much a small shot glass holds. However, I can provide you with some general information and insights based on my experience.
Shot glasses are commonly used for serving spirits and liqueurs, and their size can vary depending on the country, establishment, or personal preference. The most common size for a shot glass is around 1.25 ounces to 1.5 ounces (37 to 44 milliliters). This size is often referred to as a standard shot or a “one-ounce shot.” It is widely used in many bars and restaurants.
However, it's important to note that shot glasses can also be smaller or larger than the standard size. Some shot glasses, especially those used for specialty drinks or higher-end spirits, may hold less than an ounce. These smaller shot glasses are often used for tasting flights or for serving potent spirits that are meant to be enjoyed in smaller quantities.
On the other hand, there are also shot glasses that can hold more than the standard size, commonly referred to as double shot glasses or jiggers. These larger shot glasses can hold around 2 to 3 ounces (59 to 89 milliliters). They are often used in cocktail recipes that call for larger amounts of spirits or for those who prefer a stronger drink.
In my experience, the size of a shot glass can also vary depending on the cultural and regional drinking traditions. For example, in some countries, shot glasses may be smaller, reflecting a culture that emphasizes sipping rather than taking large shots quickly. In other regions, larger shot glasses may be more common, catering to those who enjoy stronger and more generous pours.
It's worth mentioning that shot glasses are not limited to just size variations. They can also come in different shapes and designs. Some shot glasses have a traditional cylindrical shape, while others may be wider and shorter. The choice of shot glass design can also influence the perceived amount of liquid it holds.
To summarize, a small shot glass can hold anywhere from less than an ounce to around 1.5 ounces or even more. The size of a shot glass can vary depending on factors such as cultural traditions, establishment preferences, and personal choice. It's always a good idea to check with the specific establishment or bartender to know the exact size of the shot glass being used.
