How to stock the open bar?

Pinterest has great charts on this!

I'm just hiring a bartender service and providing beer, wine and champagne to toast. Part of my contract includes the bartender, bar back and all the booze for 4 hours plus their setup/cleanup time. And, if there's anything left, I'll get to keep it. Most of our friends are beer/wine drinkers anyway and I told my FH that I would have a bottle of his favorite (Crown Black) hidden away just for him.

OP, I would suggest adding orange juice as a mixer.

We didn't stock our own bar, but I definitely suggest at least checking Costco to see if any of the items you're looking for are available.

FWIW, I think your beer and wine choices look good. I live that you've got a cider in there and Reisling and Malbec are two of my absolute favorites.

I was a bartender for years and worked a number of weddings. I must suggest that you add a light beer, like Miller Lite. It's always better to have at least one light. Liquor, stick to basics that are mid-tier/shelf. Vodka, you want 2 choices, like Absolut and Stoli. Whiskey, Jack Daniels and/or Jim Beam. A decent scotch for the older gents, perhaps Dewars. A decent rum, like Bacardi is always a nice choice to have. Don't forget club and seltzer ! STOCK UP !

You have to know your crowd but in my experience, vodka and whiskey move fast, so those are what should be stocked most of. Also, a nice coconut rum, like Malibu will go over well with girly drinks like Baybreezes.

I would say add a light beer.

Didn't read every single comment so I apologize if I'm repeating, but I would go the route of signature drinks. For my friend's wedding they sent out a drink card, and asked us to select which we would prefer. They ultimately went with beer, wine, and then for liquor a vodka based drink, dark rum based drink, and a coconut rum.

Made drink choices very easy, because there were only 6 options to choose from

Don't forget prosecco! It was a hit at my wedding ;-)
