This was my third trip to Loretto, John's first. If you've never been to the distillery, by all means pick a nice day and go. It's a beautiful drive through the countryside, the tour is free and informative, and there's a new, expanded gift gallery with a tasting bar. (And though we paid $4.23 pg to fill up on our way out Bardstown Rd, gas was to be had for as little as $3.85 pg out in the country!)

Here are a couple very short videos I uploaded to YouTube of sour mash fermenting in vast vats:
Two day mash
Four day mash
Be advised that they don't bottle on the weekend, so you will not see the bottling, packing and dipping in live action unless you go during the work week. But a recent innovation allows you to see little mini-movie loops of the bottling line on pull-down screens that have been installed directly in front of each work station on the corresponding film:
Bottling house mini-movie #1
Bottling house mini-movie #2
Bottling house mini-movie #3
More good news: Maker's Mark Toll Gate Cafe has recently opened in the "Toll House" building at the beginning of the road to the distillery. I believe they are only open during distillery tours (last one each day begins at 3:30 pm), so just lunch, no dinner service. We didn't get a chance to try it out since we were just arriving in time for the last tour of the day, but we'll try it next time we go back. It looks adorable, and there are tables outside with a view of the distillery buildings and warehouses.
