Alcohol

I'm using this as a guide!

I've heard to estimate about one drink per person, per hour. So what ever that equals to in terms of alcohol/mixer.

Hey so I had this same exact question. I've been a bartender for a long time and have done a lot of private events and parties and knew what I was bringing and what was being bought but families have preferences. When I booked my bar service I asked for suggestions and this is what they told me legally they could serve.

Here are my suggested amounts for the average crowd of 100, open bar for approx 5 hours:
Bottled/Canned Beer = 6 cases total (1 case = 24 beers) I would get 3 different flavors at the most, 2 cases of each.
Wine = 3 cases total (1 case = 12 regular 750mL bottles OR 6 magnum 1.5L bottles) I would get 1.5 cases white wine, 1.5 cases red wine.
Liquor = 2 handles (1.75L bottle) of each: vodka, gin, whiskey, rum + 1 (1L) bottle of vodka & whiskey as backup. (NOTE: Bottles that are not opened can typically be returned.)
Champagne = 1 case (12 bottles)

Those are some great guides!

Becca, how many guests are you having, and what varieties of alcohol do you plan to get? Does your caterer advise you at all on how much to get?
