Distillery visitors remark on the water supply, turned brown by dissolved peat but none of that contributes to the sweet smokiness of the whisky. Rather, Port Ellen maltings supplies all the malt, peated over Islay smoke. Whiskies lose peat over time and this one is significantly smokier than the 16-year-old core bottling. Sweet with ripe fruits and loads of medicinal smoke. Outstanding whisky, a benchmark, in fact.
