Ok Ive climbed the ladder. I started with the 12 which is great and probably the best 12 yr sherried scotch. The 15 was even better and tremendous value at $89. The 18 was absolutely divine and the best scotch Ive ever had an easy 5 star. $170 is a lot for most people for a bottle of scotch and stretches the diminishing returns quotient pretty far but I can assure you the 18 yr is worth the $$ if you can swing it. That brings us to the 21 yr Parliament which costs about $ 230(suddenly raised to 280!!!) How in the hell can this be worth that much more than the magnificent 18yr and why should you consider buying it. Well I can give you the cliches like yolo and if you got it spend it which have some truth to them or wouldnt exist and you would think yeah but F this guy its still $230. I waited until end of the bottle to finish reviewing and can now honestly say I would not repurchase this. It is a wonderful sherried scotch. The nose and palate are refined and exquisite with luscious dark red fruits and malt layered with aged leather, dark chocolate and antique wood. Finish is soft and delicate fade like a cotton ball to the cheek. It is a glorious 21 yr scotch any sherryhead will devour. The only issue here is the 18yr is better imo. It has a creamy, heavy rich flavor where the 21 is restrained and flattened . Both are superb but why spend the extra scratch when the 18 just nails it. If utter refinement and babyass smoothness are your endgame then this is for you. Either way you win......95/100
