Looking for some input on how much of each type of liquor to buy for our bar. I used the Evite drink calculator (which was really helpful) and it suggested 21 bottles (1 liter/each) of liquor. We want to have a full bar (vodka, tequila, rum, gin, scotch, whisky, and bourbon) but are unsure of how much of the 21 liters to delegate to each type. Any suggestions? TIA!
