I was in Kansis City and visited a bar which served Weller. The bartender complained that "there is something seriously wrong with your whiskey!" He showed me the bottle and the bourban was black! Well..... if you allow iron to come into contact with whiskey, it will become black. The tap water in KC has a very low level of iron in it, as do most municipal water supplies. When I pointed this out, I offered to take the bottle back to our lab and have it tested. The first test I was going to have run was to check the proof. I was told they would just throw the bottle away and buy another one. Bottom line, they were watering down the hooch and got caught with their pants down. @&%# happens!
