First off - love Watershed, Columbus distillery that takes great pride in what they do. I've been to their distillery (in Grandview) for the tour, and still rock my Watershed T-shirt out here in the bay area from time to time. That being said, not a big fan of their Bourbon, and I love Bourbon - if you want their best, go for the Four Peel Gin...outstanding stuff.
If you are just starting out with Bourbon and want something really good that isn't going to break the bank, go with Four Roses Yellow Label (you can also do their small batch or single batch if you find it instead - they are both a little more money). Keep it at room temp, and serve over a couple of ice cubes. Can't go wrong with that, and welcome to the world of Bourbon!
