i say at least 3 but don't get compleatly drunk unless it's your party (^.^)
Twenty four if we're talking 12 ounce bottles or cans.
20 to 25 bottles, depending on how much you pour for each guest.
It depends on how many people will drink wine or beer. If everybody drinks wine, then you will need to buy 25 - 30 bottles, 4 - 5 people per bottle. For beer, it is a bottle per person.
Since 2 bottles can serve 8 people, that’s mean 10 bottles can serve 40 people.
there is a 6 pack 12oz cans a12 pack and a 24 pack
if you get ten bottles, that's only three glasses per guest. so a lot would be needed!
50 bottles
6 four ounce glass per bottle so you would need 10 bottles to give everyone one glass. Have another 4 as back up incase someone wants a refill. If this is the only beverage to be served the have a couple of cases as back up
Homebrewing equipment can be bought for under $100 and will last a long time if you take care of it properly. Individual kits can be bought for between $20-50 and will make 5 gallons of beer. Ingredients can be bought seperately for about the same price. You can buy brand new bottles for around $20/per 24 bottles or you can decide to reuse store bought beer bottles if they are not the twist-off type.
Each 750ml bottle has about four glasses of wine. 20 bottles would give one glass to each person- so a reasonable host should probably get 40 bottles so each guest enjoys the gathering without getting intoxicated.
About 7.56 500mL bottles per gallon.
89oz /16oz per bottle = 5.56 bottles
