(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.
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.
200 GUESTS: 140 bottles of wine. 350 bottles of beer. 30 bottles of liquor (750 ml)
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)
Formula for Standard Drinks A government standard formula is used to determine how many standard drinks are in alcoholic beverages. The formula is outlined below: Volume of beverage in Litres, multiplied by the percentage of alcohol volume, multiplied by 0.789, equals the number of standard drinks.
The typical school of thought is to plan one drink per hour per guest. Say you want to calculate how much alcohol for a wedding of 150 for a two-hour reception. That would equal 300 drinks throughout your event. Of course, this number is just an average.

After you know how many guests you are expecting, simply calculate two drinks for each guest in the first hour and then one drink for each guest for each successive hour after that.
How much alcohol do you need for 150 guests? For a 4 hour party with 150 guests, you will need approximately 600 drinks: 240 beers, 216 glasses of wine (44 bottles) and enough for 144 individual cocktails (amounts will depend upon what type of cocktail you serve).
