This might be a more universal suggestion for large cities with wealthy denizens, but for good, small batch bourbons, I hit small, non-chain liquor stores around the city. And I always make sure to start a relationship with the owner. This often means making an appointment (seriously) during work hours in the middle of the week, but it pays off once the allocations come around. I’m not going to name my spots, but I will say they exist in the more residential/family neighborhoods.

...and seriously, make an appointment to meet with the owner.
