I'll be in Cincinnati July 8th through 11th with a day in Dayton as well. What are some must hit breweries and bars. Flying in but I will have a car.
Well, my recommendations would really depend on what you like to drink. Lots of stuff in the Dayton/Cincy area. Personally, my favorite place to go in the area is Ollie's Place in Centerville (not far from 75/Dayton proper). 60 taps, hand pulled cask, 100+ bourbons, great food, and one of the best beer shops in the area attached to it. Let me know what you like, and I'll let you know where I'd go Edit: Might not actually be 100+ bourbons, but it certainly looks like it when you go in. They do have a LOT of bourbons
Braxton brewing is just over the border from Cincinnati. That is probably my favorite in the area and well worth going. Madtree in Cincinnati. Rivertown for the lambic/sours.
We'll be hopping around different spots Saturday in Cincinnati I have zero preference but I tend to gravitate towards sours and IPAs. My old man loves stouts but it's not really the time of year for that
