Shibui 10 Yr Bourbon Cask

SHIBUI 10 Yr Bourbon Cask is a Japanese whiskey, and the name points to its main feature: the whiskey is matured in or finished in ex-bourbon casks. The bottle's details don't give an ABV, a distillery or a precise cask history, so the notes below describe what ex-bourbon-cask Japanese whiskies usually show. They aren't a measured profile of this bottle. The ten-year age statement suggests a whiskey that has had time to take on wood character without being dominated by it. Expect a profile built on vanilla, toasted oak and soft caramel, which are the typical marks of American oak that once held bourbon. Japanese whiskies often add a lighter, cleaner grain character and a gentle sweetness of honey, pear or baked apple. A trace of baking spice, such as cinnamon or nutmeg, and a faint coconut note from the charred oak are also common. Heavy peat smoke is not what this style is known for, so look for a rounded, mellow finish rather than a smoky one. Try it neat first, in a Glencairn glass. Its tapered bowl concentrates the vanilla and oak aromas and lets you judge the balance before you add anything. If the nose feels tight or the alcohol seems sharp, a few drops of room-temperature water will open it up and bring forward the fruit and grain. Once you know the character, pour it into a rocks glass over one large cube. The slow dilution softens the sweetness and suits a long, relaxed pour. Ice does mute the finer aromatics, so use a big cube rather than several small ones. In cocktails, a whiskey like this works best where its softness is an asset. An Old Fashioned with a small measure of sugar and a couple of dashes of Angostura bitters lets the vanilla and oak come through without much sweetness. A Manhattan with sweet vermouth gives a smoother, less spicy result than a rye-based one. For a Whiskey Sour, fresh lemon juice and a light hand with the syrup keep the grain flavors in view. The most refreshing option is a Highball: pour over plenty of ice, top with chilled soda at roughly three parts soda to one part whiskey, and finish with a strip of lemon peel. The Japanese-style Highball is a good way to appreciate the clean, lightly sweet character. At ten years old, this bottle is better suited to sipping and a Highball than to heavily mixed drinks.
