Last of the 3, when tasting the 12, 15, and 18 back to back. Nose is honey and a herbal quality that I can't quite nail down. Palate has a distinct lemon peel note I didn't notice in the 12 or 15 and of course vanilla. A bit of dulce de leche but on the lighter side. Finish reminds me of black tea. Overall, the quality jump between the 12 and 15 is higher than the 15 to 18 in my opinion. But still a decent sip for 80 proof blended scotch.
