In my head I have my own beverage calculator depending on the group I am planning the party for. When I meet with people to plan an event for the first time, when figuring out catering I ask them about their guests - not just do they like steak or salmon (PS unless you are planning an event for fisherman, stay away from salmon, there are other less controversial choices), but you should always ask these:
- Are these people drinkers?
- What are their drinks of choice?
- Would beer and wine suffice or should some hard-alcohol options be available? (Will someone be loudly offended if the party does not have their preferred 7 year malt scotch?)
For those of you planning an event and are bottle-count stumped there are incredible website calculators out there that will help you figure out the amount lickity-split. (PS if you are hiring a caterer they should also be able to tell you - if they cannot, I would be a little weary, wink * wink * )
Here is one of my favorites and really user friendly, its from Table & Vine.

Let me know if you ever have any questions and/or get stuck - it is a tricky thing, this thing called booze.
