Top shelf bourbon, pour it over ice. Repeat as necessary. Most bartenders seem to be able to manage.
Elijah Craig 12 year old and crushed ice. Mmm. My favorite. Also $29. But..........
Here is a little secret for bourbon drinkers. Trader Joe’s sells their branded bourbon (made in Louisville). Pretty decent $15 bourbon. Especially if your budget has been decimated like mine has this year.
