Nose: Briny, and just mildly sooty, then typical shortcomings of fresh Sherry casks used for a short period of aging: burnt matches, rubber tubes, sultanas, burnt sugar. Underneath these notes, there were pear along with apple marmalade. With time given the chocolate but also the tart fruits came out very well. Yeasty and farmy. With water added I am afraid that the rubber and gunpowder became more evident.
Palate: A clear sweetness at the arrival with a suprisingly more delicate texture, while the sherry cask definitely led to a multi-dimensional palate presenting nuttiness (macadamia chocolate), saltiness (brine), and sourness (tart fruit, cranberries). The sooty smoke was less pronounced here compared to the Bourbon cask version. With water came more gunpowder and sour-bitter cocoa.
Finish: Round and medium-lengthed. Choclatly and spirity, along with some dried fruit and gunpowders, but less medicinal bitterness and charred-wood smokiness. Solidly malty, with a trace of black tea as a finish.
