Cutty Sark is a blend of around 20 Scotch whiskies, with Glenrothes being the major component (both brands are owned by Berry Bros. & Rudd).
Cutty Sark 18y (43%, OB, blend)
Nose: fruity (peach, orange) and honeyed. A bit of sherry, vanilla, cereals and very light hints of smoke.
Mouth: soft and sweet. Toffee, caramel, lots of oranges (Cointreau) and other fruit. Spicy edge and something vaguely chemical. Rather weak attack, but it grows bolder, to a sweet, warm and smokey finish.
It’s quite elegant and smooth, very drinkable and more complex than you would expect from a blend. But for its price (€ 50-60), you could also buy a good single malt.
