If you are drinking two or more different bourbons over the course of one sitting, do you:

1) Use a fresh glass for each different bourbon

2) Use the same glass but rinse it out each time you switch brands

3) Just use the same glass without rinsing

I'm wondering if my OCD tendencies are over-complicating the process of enjoying my bourbon. I've been rinsing the glass when I switch brands.
