Taste: 2 oz in glen cairn neat and then 2 drops water. Nose (4.5): Delicious nose. Orchard fruits drizzled in caramel. Notes of leather like an old book study. There is a dustiness about it that is pleasing. Plenty of ethanol lets you know this will have a punch. The nose is strong an inviting. The first whiff is strong but let it sit and the nose is a treat. Palate (4.25): Wintergreen is on the front end. Surprises at first because I never got it on the nose. There is a hint of red raspberry on the mid palate that gives way to apples. The back palate is loads of spice and pepper. This is a spicy rye forward offering. Not for the faint of heart. Finish (4.0): Long and drying. The older bourbon really comes through here. Lots of old oak and hits of baking spice. My chief complaint is that it may be too drying. Finish was my least favorite part here. Overall: First, I like what Four Roses does. They batch from ten different recipes which are derived from 5 different mashbills and 2 yeast strains. Each single barrel is distinct on its own. This blend is a treat of some fine 15 and 11 year old whiskies and a 21 year old to boot! But you do "pay at the pump" so to speak. $165 retail is alot of commitment. If you are a Four Roses geek.....don't hesitate, buy it. If you are just getting your feet wet, experience the Single Barrel Select for way less first. Would I buy a second bottle- no. Was the experience worth it to me-- maybe. I really want to see how this one opens up.
