A shot glass
A Single Glass Of Wine Is Equal To How Many Shots?
A “standard drink” refers to 14 grams of pure ethanol alcohol. By these parameters, a 1.5-ounce shot (40% ABV) equals a 5-ounce glass of wine (12% ABV).
For accurate measurements, the bartender would have to use a jigger for every drink. Shots tend to be more consistent because the average shot glass holds 1.25 to 1.5 ounces.
All the liquors in the back bar clock in at 40% ABV, while wine alcohol levels can differ significantly from one blend to the next. Wine glasses can also vary in size.
For example, an 8-ounce glass of Zinfandel can be between 15%-20% ABV, which is closer to the equivalent of two shots of a liquor with a 40% ABV.
