How much on average can I expect to pay for Alcohol?

Are you bringing your own wine into the venue or are you paying for the open bar at the venue? From my experience, paying for open bar will mean everyone will be covered for open bar not just the 25 people. If you're bringing your own wine, it depends on how much each bottle of what you like costs and you should ume that all 25 drinkers will have a minimum of 3 gles. So say you buy a bottle of Merlot for $25 and a bottle of Riesling for $18. You should expect to have 2 of each bottle for every 8 people. Figure out that cost. If it costs extra for corking and pouring services, figure that into your total. I'm just going with the open bar option because our wedding is all adults and we're not sure out of 125 people who all will be drinking. It's easier for us to just do the open bar.
