I know this isn't really etiquette, but you guys seem to have all of the answers so I figured I would put it here. We are proving our own alcohol for the reception and I'm struggling to figure out how much to buy.
Important details! Its going to be a Saturday afternoon wedding, reception (including a cocktail hour while we take photos) from 12-3 or 4. Only about 50 guests with probably 20% light drinkers, 60% moderate and 20% heavy drinkers. Super informal, think pretty much just a slightly fancy family BBQ. It's going to be outside in the fall at a private park that is about a 30 minute drive on a winding two lane road from town (super normal and expected drive for this area!).
We are planning on doing an open bar for beer, wine and champagne. There will not be any hard liquor available. We plan on offering a light beer and a dark, a red wine and a white plus plenty of champagne for toasts and people like my sisters and I who like a glass or two at weddings. Plus some iced tea, lemonade and water for N/A options.
Thanks for any guidance you can offer and let me know if I left out any important info!
