I loved the 12, 12 CS, and 15. You'd imagine I'll enjoy this as well. Redbreast is always a winner--I expect nothing less of the 21. This is the oldest Irish I've ever owned and the second oldest whiskey overall. For context, this is the old-style silver packaging, meaning it's a bottling from at least a few years back. Let's check it out.
Nose: Red apple, pineapple, mango, orange, honeydew, cantalope, pear, plum, and apricot. It's a fantastic mix of fruit, both tropical and orchard. Caramel, vanilla, and sugar cookie. Maple pecan. Brown sugar, toffee, and honey. Roasted nuts, some baking spices, and a heavy hit of oak. Phenomenal nose.
Palate: Red apple, cranberry, raisin, date, fig, and pear. Plum and black cherry. Apricot and orange. Cola. Caramel, milk chocolate, vanilla, honey, shortbread cookie, toffee, and Cinnabon. Maple pecan. Roasted nuts: cashews, walnut, and almond. Awesome.
Finish: Hits heavy for a 46%'er. The roasted nuts hit hard again. Apple, pear, apricot, and raisin. Caramel. Cinnamon, black pepper, clove, nutmeg, and oak spice carry this out to what makes for a moderate-long finish.
Sometimes, when you find a distillery or a brand that you really enjoy, trying the higher end offerings leads to disappointment. This by far the most I've paid for any incarnation of Redbreast, and it is also by far the best. It's simply amazing at every turn.
Not only is it the best of any Redbreast bottling, but it's the best Irish whiskey--and one of the best whiskies I've ever had. At $323, it'd be hard to justify the purchase without this review. Generally, I'd say this is too expensive for any bottle of whiskey. This, however, is not your average whiskey. It's absolutely one of a kind, and truly one of the best I've ever had. If it's in the budget, try this if you're a fan of whiskey in any form.
