I don't see this suggestion by itself, so sorry if I missed it:
I'd love to have a brewery building that is separate and unlocked before the Tavern, please
Many households brewed their own ale.
I think a separate small building would be great, could have tier 1,2,3 and start as simple roofed structure with wattle and thatch, and then upgrade into wood and stone, with additional drink recipes unlocked along the way
