The Old Fashioned is my favorite drink. It introduced me to whiskey and mixology plus it's simple and versatile. I think it's easy to judge if a bar has good cocktails based solely on their Old Fashioned. What are your opinions, favorite variations, etc?
It's definitely a good format for keeping a cocktail spirit forward. I also really like making mezcal old fashioneds from time to time. It's a great way to bring out what a new spirit is best suited for.
