How much alcohol for a party of 15 ?

Hi everyone,

For info, i’m from Europe, group age around 25, people for a weekend, arriving late friday night (so mostly eating and beer), and party saturday afternoon / night (cocktails) with BBQ.

Group of 13 confirmed, pbly 15/16 in the end.

I planned :

beer : 25 cans of 0.5L of beer (only around ~10 ppl drink beer) so 12.5L

softs drinks : 11L

liquor : 1L

2L Vodka + 2L Liquor – 8/9L of cocktail

1L Gin – 3L cocktail

1L Rhum – 2.5L cocktail

0.7L 40° regional alcohol – only 4/5 will drink, 3/4L mix with water

What do you think ?

It’s pbbly enough but i wanted to be sure, i dont host often that many people.

Thanks everyone that’ll post.
