(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.
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.
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.
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.
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)

So as guide, if you have 100 guests, you will need around 50 bottles of wine (mix of red and white.) Plus around 300 pints/bottles of lager, beer and cider.
A good rule of thumb is to buy 10 bottles of vodka, 6 bottles of whiskey, 6 bottles of gin, 4 bottles of scotch, 2 bottles tequila, 2 bottles of triple sec, 2 bottles of vermouth, 4 cases of beer, and 2 cases of wine for every 100 guests.
