Event rental companies rent out taller tables for use as a bar, or actual portable bars designed for just this purpose, but a regular table works fine too. For the tables, it's nice to get a long tablecloth to hide any cases or coolers.
For a 4 hour party with 100 guests, you will need approximately 400 drinks: 160 beers, 144 glasses of wine (29 bottles) and enough liqueur for 96 individual cocktails (amounts will depend upon what type of cocktail you serve). If you aren't serving wine, plan on 240 cocktails.
(So for a six-hour wedding with 100 guests, you'll need roughly 600 drinks.) Alex Tornai, party planner for Binny's Beverage Depot, errs on the side of more drinks per person (and we're here for it): “Two drinks in the first hour and one drink per hour for the duration of the evening,” he says.
A good rule of thumb for estimating is 2-3 drinks per person for the cocktail hour, then 1 drink per person per hour for the rest of the reception. So for example - for a cocktail hour then 4 hour reception for 65 guests you'll need to be prepared to serve at least 350-400 drinks!
Using this rule, if you have 100 guests at your wedding, and you're planning a five-hour celebration, you're looking at 600 drinks total for the night. Keep in mind that this doesn't include champagne for toasts, which is usually added in addition to your other alcoholic beverage options.
Full bar – Beer, wine and liquor: 100 (guests) x 5 (hours) = 500 drinks. 500 x 0.33 = 170 beers or 7 cases of beer or one ½ barrel sized keg. 500 x 0.33 = 150 glasses of wine, /5 glasses per bottle= 37 bottles of wine. 500 x 0.33 = 150 mixed drinks, /39 servings per 1.75 bottle = four 1.75ml bottles liquor.
Open Bar for 100 GUESTS: 70 bottles of wine. 175 bottles of beer. 15 bottles of liquor (750 ml) 20 bottles of champagne for toast (optional)
