Tamdhu is well-known and much-adored for its excellent use of sherry casks, and those of you with a penchant for single malt with heavy sherry influence will be delighted to know that the distillery's 15 Year Old expression continues that theme. This one has spent is maturation in oloroso sherry casks, resulting in generous helpings of dark fruit and Christmas spice. Nose: Charred pineapple, earthy barley and a hearty slice of dense fruitcake, then some toasty oak warmth, orange zest and fennel. Palate: Still packing heavy dried fruit notes, with a hint of orange oil and dried apricots cutting through. Earthy vanilla appears later on with touches of cedar, leather and cinnamon. Finish: Warm and sweet, with waxy peels, clove, chocolate ice-cream and oily walnut. Overall: Another terrific Tamdhu tipple!
