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.
Total for 100 Guests: 70 bottles of wine. 175 bottles of beer. 15 bottles of spirits.
There's nothing worse than a wedding where the bar runs dry. A general rule of thumb is. you want to account for one drink per guest per reception hour, but for cocktail hour, you want to account for two drinks per guest per hour. Tend to drink more during cocktail hour. and then slow down during dinner and dancing.
(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.
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).
When planning an event, the average consumption per person is one drink every 45 minutes. If the event will last 2 hours, plan on 3 drinks per person. Start with your best guess of the drinking habits of your guests. Divide the number of guests between the types of beverages you plan to serve.
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!
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.
