The Standard Drink in México

73 T he S tandard D rink in M exico | F ormulas and applications The result of this operation is how many milliliters of Tequila we should pour to serve a Standard Drink with a content of pure alcohol of 16.560ml. A typical tequila shot glass is usually an ounce and a half (approximately 43ml), which roughly translates into 16.34ml or 12.82g of pure ethanol. Let’s keep in mind these values are approximate. If we wanted to obtain the standard drink measure (16.560ml or 13g of pure ethanol) of a beer with a 4.5% ABV, applying the same formula, we would know to serve 368 ml. Beers in Mexico usually come in 355ml containers, which is similar enough to a standard drink, but not exact. (15.97 or 12.54 g or pure ethanol). To know how many standard drinks there are in our tequila bottle or in any other drink, we would have to know the quantity of pure alcohol that it contains. As we have already explained, in Mexico drinks are marked with “% Alc. Vol.” (ABV), according to the percentage of pure alcohol that they contain. To know this percentage expressed in milliliters we have to solve a rule of three, in the same way we would solve it to know the final price of something in discount we’re interested in buying: Once we’ve obtained the result (e.g., 285ml EtOH) we divide it by 16.560ml, how many millilitres a Standard Drink contains:
