Used Fourroses sb and kirkland brut.
To me it is quiet enjoyable as is.
But personally it is a cocktail one would make to use up all the champagne and not something to open the bottle for.

Very refreshing and vibrant recipe!
But 60ml gin seems a bit too much so I dialed it down to 45ml.
Also depending on the status of your juices, you might want to tweak the ratio of the juices to balance it out.

made it with nardini submix (averna2 : cynar2: fernet1) instead of only cynar cause the comments weren't very positive about it. And i really like it, though the scotch does really die and only leaves a slight malty feel, ruby port and the nardini submix plays very well together.

tbx! bought a justinos 5y med dry for this
