I would guess that Hill and Hill remained at that plant as long as the name was in use, so it wouldn't be a "little brother" in the way that Sunny Brook was at the Old Crow/Grand-Dad distillery in the '60s to '80s.
From here, Mike drives us to an industrial area where we turn down a short gravel access road to a parking area where we can see, all around us, no less than four plants that had once been well-known bourbon distilleries. Directly in front of us stands a group of buildings where people are going in and out to work. Whatever the buildings are being used for today, this was once the site of Hill and Hill, a well-known bourbon distillery that John remembers from as recently as maybe twenty-five years ago. Mike explains that they had both brick and iron-clad warehouses, and examples of both are still standing. The iron-clads are obviously abandoned, but the brick buildings appear to be in use.
