Glenlivet 15yr
Nose
Bright green fruit, some green grape skins, and acidic apple. White sugar, and raw cane juice. Some interesting (but mild) spices, cinnamon and nutmeg from the French oak.
Palate
Light. Some mild wood. A bit raw on the alcohol (like the 12), and perhaps somewhat watery. Golden raisins.
Finish
A twist here: maybe dried raspberries? Some nice dry tannins. Medium long, with a surprising touch of lime oil at the tail end.
