I have a full bar. 12 taps, 50 different bottled beers, hard liquor as well (20 whiskeys, 6 gins, 6, vodkas, etc…). In fact We planned to open a bar and ended up with a pizza pub as the pizza became quite the draw. I do anywhere from 20 to 75% alcohol sales depending on the night (weekdays are definitely more pizza oriented, Last Saturday was one with 75% alcohol sales) I’m a barman at heart and I love that aspect of the business even though I’ve been back in the kitchen training the new guys for the past month. Over here a liquor license costs like 500$ and 30 minutes of paperwork filing so no big deal though. That said drunk people do dumb stuff and I’m actually thinking of opening a second take-out/delivery only location that would not deal with any liquor. There’s tons of money to be made with booze, but there’s also a ton of work behind it too. I have 5 bartenders so labor right there is nuts. Then you have to worry about theft (over-pouring is theft for example) not to mention you have to know all of the cocktails, beers, liquor, it’s a whole other thing that you have to step your game up on. At a minimum if the licensing is an issue beer a wine are musts. Wine by the glass has been very profitable. just keep you selection small so you don’t have 6 open bottles turning to vinegar. We do a house red and a house white served chilled and never have to worry about it going off. before I used to have a wine list that I sold only by the bottle with 5 different wines and they never moved. Draft beer is fine if you have a good system for it. avoid long draft lines. maybe even look at getting a freestanding kegerator kind of thing (Our Heineken rep wanted to give us one for free! I said no though because of the design of my bar I would have nowhere to put it, and we do more craft beer so Heineken isn’t really a good fit). If I could do it again I’d probably go with 6 or 8 drafts instead of 12. 12 is pushing it for us. more than that and I’d be worried about the freshness of the beer. Again though your size and customer base will determine how fast you go through stuff.
