d Generally speaking, about seven grams [0.25 ounce] of alcohol are eliminated per hour. A standard drink varies from country to country. The World Health Organization defines a standard drink as containing 10 grams (0.35 ounce) of pure alcohol. This is the approximate equivalent of 250 milliliters of beer [8 ounces], 100 milliliters of wine [3.4 ounces], or 30 milliliters [1 ounce] of spirits.
