Tried this one a couple of times. You really need a bright, fresh, new world Savvy B (I went for an Awatere Valley from New Zealand) to stand up to the ice wine. Lovely tension between the two wines while the gin plays referee.
What a cocktail! Fascinating to see how different people taste it. For me, this is about the tequila/mezcal and the absinthe coming together via the vermouth to give beautiful off-dry creme de cacao note, lovely earthy and sweet floral interplay too. Great stuff!
