I doubt if they're still doing it, but Austin Nichols (Wild Turkey) in Lawrenceburg, KY used to conduct tours. During the tour they would allow people to sample their bourbon from every year from when it was green until it had aged 8 years in order to taste how the aging process mellowed it. 8 little shots of Bourbon in a one hour tour.
A friend took the tour and showed up at my place afterwards with a significance buzz.
The DUI laws are a lot stricter now than they were then. So I doubt if they include that element in their current tours.
