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.
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.
Plan on one drink per guest for each hour of your function. Let's assume you are throwing a 4 hour evening party for 100 guests. In other words, 100 guests x 4 hours = 400 drinks.

A good rule of thumb is one bottle of wine per two guests, three beers per guest, three cocktails per guest, one bottle of Champagne or sparkling per six guests, one litre of water per four guests, and three non-alcoholic drinks per guest.
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.
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.
