Immediately after pouring there's the clear sherry sweetness of the oloroso finish. Treat this like the older whisky it is, there's no point rushing things. I gave it an hour with just a tiny dash of water and it opens up into a jammy fruitfest.
Sweet and sour blueberry jam, blackberries, sour cherries, sultana raisins and sweet cookie notes (actually pretty close to the soft Dutch Sultana brand biscuits, filled with currants and raisins). Also some cooked apricot and plum with an (over time) somewhat deminishing leather note. Finally there's a lighter style of chocolate accompanied by a hint of nuttiness in the background.
Thick and syrupy, quite a lucious and round mouthfeel with the same sweet/sour forest berry style of fruitiness one gets from the nose. A more dried kind of plum and apricot, vanilla cream and scones. Caramelly chocolate, a slight note of sweet tobacco and some bitter oak, also reminiscent of old book shelves. Al in all it's just very pleasant stuff to keep slowly swirling round the tongue.
A fairly long aftertaste with initially some jammy forest fruits followed by clear notes of darker chocolate, caramel and mocha. At the tail end it displays a nice oaky liveliness with some mild tobacco and peppery baking spices.
