Orphan Barrel Muckety Muck 25 is a rare single grain Scotch whisky crafted from select distillates obtained from the now-defunct Port Dundas Distillery in Glasgow, which ceased operations in 2010. Diageo released this limited edition whisky in 2021, after aging it for at least 25 years in American first-fill casks. The result is a singularly exquisite single grain whisky, imbued with a unique character and vibrancy. Bottled at 45.5% ABV, OB Muckety Muck 25 Year presents a bouquet of fresh lemon, creamy meringue, and sugared ginger immersed in caramel. Its flavor profile comprises notes of vanilla, butterscotch cookies, citrus, and lemon-ginger tea, culminating in a sweet, bright, and somewhat minty finish with a delicate earthy undertone.
