Zingy, sweet and sour, fruity and bourbon-laced. The sugar syrup is my own addition, and depending on your lemons and tastes, you may want to either omit...
Huh! A nearly identical cocktail, with lime juice in lieu of lemon, seems to be known as the "Churchill" cocktail or "Churchill Manhattan" – interestingly, no mention of either is to be found on your site!
At a bar in my home town, they served it on the rocks (and under a cloche filled with cigar smoke in a tribute to its namesake), but serving it up seems the norm. I make it with rye for a bit more sharpness, and I find that bianco vermouth makes for a nicer color in combination with the lime.
I believe the Churchill or Churchill Manhattan is properly named a Sir Winston. I've added a link under "variant" above. Also, please see the pic on our Joe Gilmore page.
