Tipperary (PDT ratios on the left, and Bartender's Choice ratios on the right) with Green Spot Irish whiskey, Cocchi vermouth di Torino, green Chartreuse, and Regan's orange bitters for the Bartender's Choice version. Compared to the traditional (Harry Johnson) version, PDT only has a rinse of green Chartreuse. It still makes a great cocktail, but I feel it changes the feel of it quite a bit and makes it resemble a classic Manhattan compared to the Bartender's Choice version.
As a side note, I am slightly disappointed by the Green Spot. I am a novice at Irish whiskey and prefer Redbreast. Maybe it will grow on me.
PDT calls for Black Bush. I wonder how that compares in this drink?
