When you are planning an event with bar service, you need to know how to stock a bar. It always pays to estimate slightly high because running out is infinitely worse than having slightly too much. To perform an estimate, it’s best for you to plan bar list for party with 100 guests. Thereafter, based on the number of people you actually have, you can simply apply a modifier to the bar supplies you need.
For example, if you need 12 assorted cases of spirits and wine, 10 pounds of garnish, and 100 glasses and mugs for a party of 100 people, you would multiply each number by 1.35 if your final guest list were 135 people. To be safe, it would be prudent to apply an additional 5 percent to each number. Reverse the process for events of fewer than 100 guests, applying the 5 percent.
