Outstanding cocktail, my favorite take on a champagne cocktail , for sure better, deeper, more interesting than the traditional champagne cocktail.

I should mention that I do prefer only 1 dash orange bitter and only 1 dash booker's/bogart's bitters. And I use Merlet Soeurs Cerises Liquer instead of Herring's. Gives a more subtle cherry taste, which I prefer, so you still taste the cognac and the champagne.
