The Black Thorn.

This Black Thorn is all about Irish whiskey

A good drop of the Irish — something with a bit of weight to it — is ideal for mixing. Not as big in the mix as rye, nor as smoky as some Scotch, Irish whiskey hits that Goldilocks quotient of being ‘just right’, as it is here in the Black Thorn.
