Drink servings are not all the same size. This chart lists the standard pours so you can plan batches and track intake.
| Drink | Standard serving |
|---|---|
| Espresso shot | 1 oz (30 ml) |
| Coffee mug | 8 to 12 oz |
| Tea cup | 6 to 8 oz |
| Wine pour | 5 oz |
| Beer | 12 oz |
| Cocktail | 3 to 5 oz |
| Soda can | 12 oz |
| Water glass | 8 oz |
A coffee cup is not 8 oz. Coffee makers rate a cup at 5 to 6 oz, not the 8 oz measuring cup. That is why a 12-cup pot fills about eight mugs.
FAQ
Why do standard drink sizes matter for caffeine tracking? Caffeine content is usually reported per standard serving, not per specific cup, so comparing a larger coffee to a smaller standard serving without adjusting for size will overstate or understate actual caffeine intake. For most home brewing, a standard measuring cup is 6 ounces of water, not the 8-ounce cup used in general cooking, which trips up a lot of home brewers.
