Bottle open several months, about 75% full. Served in a Glencairn glass, 1.5 oz pour, neat. I've been on a Islay kick the last month or two, and it felt good to come back to Speyside. A Sherry bomb, to boot! It does, however, continue the trend of my apparent affinity for barrel proof drams. The nose is ALL Sherry. Pure dessert. There is an oak hint, so there is some old-ish whisky here, but the core is probably 10-12 years old. Entry is sweet and smooth, especially for the ABV. Mouth feel is thick, full, and lush The profile starts with Sherry, then dried fruits lead way to walnuts, then a milk chocolate that morphs into dark chocolate. The chocolate profile is reminiscent of dried tobacco that is kindling. Finish warms up, with a lot of spice, and even some burn on the finish, although the burn didn't appear until near the end of the glass. It would be prudent to add a few drops of water to bring the ABV down to ~50%, but I couldn't bring myself to do it. TLDR: Complex, very approachable, and addictive. I am heartbroken I cannot get may more of this, and it's unknown when or if Batch Strength #4 will be available in my area. Pity, this is one of my favorites, and possibly the best bang-for-the-buck cask proof Sherry bombs on the market.
