In most recipes for the Liberal, it calls for either bourbon or rye. For the sake of science, I decided to make one of each.
The Liberal
3/4 oz 101 proof Wild Turkey Rye or 94 proof 17yr Vintage Bourbon
3/4 oz Carpano Antica
3 dashes of Torani Amer
1 dash of Regan's Orange bitters
The result: Tie. They are both super excellent drinks and I love them both. If I had to choose one, I would go with the smoother and slightly sweeter 17yr Vintage Bourbon but if you asked me tomorrow or 20 minutes from now, I could easily change my mind. Better finish this post before I do change my mind again.
