What is “one standard drink”?
As most college students do not measure a standard drink (i.e. red solo cup), they tend to not measure the amount of alcohol in a cupful. It is important to remember that ‘1 drink’ is not one cupful---it is how much alcohol is actually in what you are drinking. Knowing how to count a standard drink is necessary for understanding how much alcohol is in your body and to correctly calculate the BAC or blood alcohol concentration.
One drink = one 12-ounce beer or the second line from the top of a red solo cup. This is normal-strength beer (4% alcohol). Micro-brews and malt liquor have a higher percentage of alcohol (check the label).
One drink = 5 ounces of standard wine or the second line from the bottom of a red solo cup. This is most table wines: white, red.
One drink = 1.5 ounces of liquor (40% alcohol or 80 proof) or the bottom line of a red solo cup. This is how much whiskey, vodka, gin, etc. is in a measured mixed drink or in a standard-size shot glass. Remember that mixed drinks may not be measured and often contain far more than 1.5 ounces of alcohol. Drinks with a higher proof (like grain alcohol, Everclear, or 151 proof rum) should be treated with caution.
One drink = ??? Jungle juice is a combination of various liquors (i.e. everclear, vodka) fruit juice, and may or may not contain chunks of liquor soaked fruit. The concoction consists of upwards of 20% alcohol, though this is not a confirmed measurement. Generally, the assumption is that one cupful is equal to 5 or 6 shots is equal to 5 or 6 drinks. This can be a dangerous mixture to ingest as each mixture varies depending on the ingredients.
