Continuing my review of the 12, 15, and 18 back to back. I think the lackluster 80-proof will be holding them all back, via a watery mouthfeel. Nose is vanilla but a very welcomed clove/all spice note not present in the 12 year. Mouthfeel is caramel (again), touch of apple. Finish has notes of orange rind and faint hint of oak.
