Squeezed in another walking tour on Louisville before heading for Nashville. This one's purported to be about bourbon, and it was, but it was also savor history and architecture in the the downtown area. This city office building, for example, has heads of pigs, cows, horses and mules representing the city's agricultural past. You can see them over the windows in the photo. Bourbon distilling really got started in the 1780's and eventually standards were established that define what can be called bourbon. These include that it must be at least 51% corn, and nothing in it other than corn, water, and other grains. It can't be more than 160 proof, and it must be aged in a new oak barrel (charred on the inside). No colors or flavorings can be added. Dinner tonight at an Uzbekistani restaurant. Yum!
