In 2016, Amrut Distilleries launched a unique cask-finished whiskey, the Amrut Spectrum 005. This single malt whiskey was finished in a cask assembled with staves from five different barrels, (the name is a reference to the spectrum of staves). The distillery claims to have invented the mixed stave cask finishing and it does not sound like an easy task. Keep in mind that these staves varied significantly in terms of grain, age, thickness, and size. All of these factors had to be carefully managed to produce a liquid-tight barrel that would allow for equal exposure to the different wood types.
Given the intense impact on the whiskey, I think it’s important to discuss these two sherries. Oloroso Sherry is a type of fully oxidized sherry typically bottled dry. Though the base wine is quite neutral, much like whiskey, its aging process gives it its unique flavors. These flavors can range from dried fruits, toasted nuts and seeds, to more chemical and umami flavors such as shoe polish and mushrooms. PX sherry is a dessert style of sherry made from the Pedro Ximenez grape that is often sun-dried before fermentation to concentrate its flavors and sugars. The resulting wine typically resembles molasses for its syrupy consistencies and dark and opaque color. It often shows aromas of raisins, dark chocolate, or dried fruits.

Tasting Notes: Amrut Spectrum 004 Single Malt Whisky
Vital Stats: Aged in ex-bourbon cask and finished in a cask assembled from staves from new American oak, new French oak, ex-Oloroso sherry casks, and ex-PX sherry casks. 50% ABV, SRP $195/ 750ml bottle.
Appearance: The color is dark amber-brown.
Nose: There’s a lot going on with the nose. It opens with spice notes like caraway, musk, star anise, and toast. There’s a suggestion of shoe polish, roasted sweet potato, and burnt vanilla. The influence of the four stave types in the finishing cask is prominent! There are notes of candy corn, caramel, and dried mango. The mélange of so many aromatics does seem a touch disjointed. The entire experience is a bit like smelling a bottle of fine perfume: a suggestion is nice, but it becomes overwhelming.
Palate: The taste is of sweet perfume and spices with a strong toasted vanilla note. It shows hints of sandalwood, pond water, matchsticks, and seaweed. There’s a cereal note to the finish like breakfast porridge sprinkled with caraway. The evaporation on the finish is pleasant with a mild tannic feel on the tongue.
