The Collectivum XXVII is the rather epic name given to a limited edition blend from Diageo. Why’s it special? Because it contains whisky from all 28 of Diageo’s active Scottish distilleries. Bottled at 57.3%, it’s been aged in a combination of refill American oak hogsheads, refill European oak butts, ex-bodega European oak and first-fill bourbon casks. Epic.
