- How many mixers are needed for a party?
To figure out how many bottles you need, just divide the number of liquor drinks needed by 16. To estimate the amount of mixers needed, figure about 1 quart (1 liter) of tonic water, soda water, or juice for every 3 guests. And don't forget to round up and, if possible, buy a little more than you think you'll need.
