And seriously, not all 100 of those people are going to drink. FH and I are doing the same thing as you, beer and wine, and only 100 people. We're figuring, with the help of FFIL, we'll need about 30 bottles TOTAL max. We have figured like six cases of beer I think.

Assuming 1/2 your guest drink 2 glasses each, you would need 25 bottles. If you know you have more beer drinkers than wine drinkers, assume 1/3 of your guest will drink 2 glasses each and get 17 bottles. Or 1/3 will drink 3 glasses each and you would still end up needing 25 bottles.

It really depends upon how long your reception will be and how many of your guests drink (and how much they usually consume). I had 8 cases of wine, at my daughters wedding. 3 cases of that were bubbles; 3 cases of red and 2 cases of white. There was also a full bar. There were 134 guests.

I mean, 78 bottles of wine for 100 people, think about how much wine that is people.... you're giving almost a full bottle to every single person PLUS beer, PLUS champagne. The realsimple calculator is just as ridiculous. That would end up being two bottles of beer and 3/4 a bottle of wine PER PERSON.
