I am putting on a rehersal dinner for just over 50 guests and will be supplying the beer and wine for the evening. From what I have gathered, one bottle of wine for every 2 people seems to be the general consensus for what to keep on hand. What types of wine should I provide? Of the 25-30 bottles, should half be white and the other half red? One type of white and one type of red?

What about beer? How much should I provide? How large of a selection?

Thank you in advance for you help.
As far as the pairing of wine or beer to the menu, I am waiting on the chef to finish creating the menu before asking what she feels would be a good compliment to the dishes. Idealy I would buy wines that compliment the dishes being served. However I am still stuck with the question of how much wine to bring. There is an open bar at the rehersal and my better half has already mentioned that hung over people at the wedding may not be "in my best interest."

I also do not mind going over in the wine department, they keep well and we will undoubtably work our way through them in the following year.

Are kegs at a rehearsal dinner tacky?

Side note, the dinner is at an art gallery. I dont know if this should warrant a change in any suggestions or not… but…

I have to bring a bottle of wine to a wine tasting party. I have this spare bottle around the house. If I bring this, will people laugh because it is a cheap, low quality wine? Or is it a decent, respectable wine?
