One year ago I mixed a batched Manhattan Island and aged it in a TEN30 barrel I've used to age multiple Manhattan variations. My version was made with Hennessy VSOP, Cocchi di Torino vermouth and Luxardo cherry liqueur.
Made with Cocchi Storico Vermouth Di Torino and just a couple of dashes of Angostura it was a deeply flavoursome, strong drink. Good to have after a hard day!
Exquisite!
