Interesting but don’t love it. Didn’t quite come together for me. Spec plus one dash each bitter truth aromatic and Jerry Thomas bitters, and plenty of dilution. Would consider retrying.
With this one we substitute Cocchi Vermouth Amaro (Dopo Teatro) for the dry Vermouth and use Boker's Bitters. That way, one can up the Rye Whiskey volume a tad (say by 5ml), if one wishes. Cheers.
