Using the proof calculator I estimated that I need about 2.5 parts of Stagg at 144 proof to 1 part water to get a final proof of 107 (which is about the hottest I like my bourbon).
I've been adding water in this ratio each time I have a pour and figured I could save some time by adding some spring water to the bottle and pre-mixing to 107 proof. So I did it. I now have full bottle of GTS right where I like it. But I feel like I've sinned somehow
Anyone else do this, or have you avoided doing this for some other reason, such as wanting to retain the option of tasting a really high proof product now and again?
