I tried this looking for a good application for my walnut liqueur, and like this more than I thought I would. I used Cocchi vermouth, and the result is nutty, with just enough spice and bitterness. I've never tried Dubonnet Rouge, so I'm not sure how much of a departure my version is.
I have to admit that I've never tried this. I have never had Dubonnet. The Cocchi Vermouth di Torino is noticeably sweeter than other vermouths. How was the sweetness? I think I'll give this a try later tonight with Punt e Mes, which sounds pretty darn good.
Thanks for putting me on to this. I made it with Punt e Mes and another 3/4 oz of dry vermouth. Next time, I'll split the vermouth, rather than add more. Very nice drink. I used Nux Alpina, which is pretty strong. 1/4oz was just the right amount. A very nice fall / winter cocktail. Of course it's always raining in Tacoma, so you can enjoy it year round. ;)
