You’re having a party and find yourself standing in the liquor store wondering just how much alcohol to get. Sound familiar? I’m of the mind that it’s always better to be safe than sorry, therefore I have a tendency to way over-buy. That’s fine by me as I really don’t mind having plenty of leftovers, but there is actually a science to this. In general, it’s based upon how many people are going to be coming and how long you plan for the party to last…and of course you’ll also have to factor in the drinking habits of your guests. There could be lots of variation in that realm! Here’s a handy buying guide to help get you started. Happy Holidays!
