Comparing this to the last dram from my bottle of 15 year. Honey and malt dominate the nose with only a hint of peat smoke. Rich and briney on the palate. Much more savoury than the 15. Honey, cereal and lots of spice. Exceptional balanced and complex. Finish is lengthy with lots of char and bourbon notes. The age has really tamed the smoke on this and cranked up the barrel effects. I didn't love the 15 and always found it a little uneven. This on the other hand is a bottle I will be savouring for a long time.
