Calvados & Tonic is in the end kind of a Christmas riff of the classic Gin & Tonic. Swapping gin for apple brandy means you end up with a slightly less bitter cocktail, with the apple shining through quite noticeably. If you want to make the cocktail even more Christmassy you could add a few drops of allspice dram at the top of the forming foam.
Cheers, and Merry Christmas!
