How much alcohol for a 30 person party

ALOT!!! i would ask people to bring 1 bottle of alcohol or a 12 pk of beer- that will help- but for sure have 4 cases of beer and a few different types of hard alcohol on hand, along with cranberry juice and some soda mixers

As much as you can fit in your car!!!

Go to virtualbartender.com. It can figure out how much of what you need for any amount of people, and divide it by percentage booze, beer, wine. It will give you amounts to buy and has tons of drink recipies, party themes, etc. Check it out.

depends on how much you can drink.
maybe like 30 24 packs idk though

I have an big Halloween bash every year I make up some of my famous Witches Brew & keep enough on hand to make a 2nd batch if need be.
(this one pretty much fills a 12-quart cauldron)

four 48 oz cans pineapple juice
one 96 oz bottle orange juice
four 2 liter bottles lemon-lime soda
one 1.75 liter bottle vodka
one 1.75 liter bottle rum

I also tell everyone that I will make the punch & if they want anything different to byop (bring ur own poison)

I had a halloween party that had about 20 people show up. It was BYOB but just incase, we had a bottle of Sauza tequila, two 30 packs of keystone light (cheap but effective lol), and a 12 pack of newcastle. (I highly recommend buying a 12 pack of keystone ice or natural ice, it has higher alcohol percentage per can which = more drunk, less needed). Others brough six 32 oz of Millers, a bottle of captain morgan, and some hypnotiq. Tell them its BYOB as well!

jungle juice? hmmm i think that beer would be the best choice, but that is just me

i would say uhmmm 6 things of the 12-pack beer things.
^wow i'm really good at explaining this

sounds like it is gonna be a fun partyy (:

all say if they are real drinkers,
atleast 5 beers per person and half a bottle of hard alcohol each or you can always say BYOB!

20 Cases of beer (12 pack),
5 Bottles of booze
