If you’re planning on stocking your own bar for your wedding then working out how much alcohol you need to purchase may be giving you a headache. The steps below will help you to calculate this – but remember to consider your guest's tastes, for example, my friends and I are big gin drinkers so I would purchase more gin than I would vodka.
1. What to Stock
You don’t need to stock all options but it’s good to have a selection:
Champagne and/or Prosecco
You will also need the following:
Lemons & Limes
2. How Many Servings
Guests will drink an average of 1.5 drinks per hour so to work out how many servings of alcohol you would need simply multiply the number of guests by 1.5 servings by the number of hours.
no. of guests x 1.5 x no. of hours = no. of servings
Some things to consider:
People will pour heavily at self-service bars so if your guests will be serving themselves plan for more.
If it’s going to be a hot day then plan to get through more cool drinks and water.
People tend to drink less the earlier the wedding is as well as on weekdays and Sundays.
3. Serving Sizes
You’ll need to know how many servings you can get out of each bottle in order to calculate how many you need to buy.
Wine: 4 servings per bottle
Beer: 165 servings per keg or 1 per bottle/can
Liquor: 18 servings per bottle
4. Calculate Your Ratios
Think about your guests – what do you think they’ll be drinking?
The example below is based on 100 guests attending a 6-hour wedding, 30 are beer drinks, 30 are drinking wine and 40 will be drinking some form of liquor.
100 guests x 1.5 x 6 hours = 900 total servings
360 servings of liquor = 20 bottles
270 servings of beer = 270 bottles/cans or 2 kegs
270 servings of wine = 68 bottles
