Both very similar and sweet, so what were the biggest differences? On the nose, the Oloroso showed me more nuttiness, a bigger acidity and a heavier attack. The PX was definitely the more sugary whisky. On the palate, it's not about the notes but the mouthfeel. In which the Oloroso is a lot hotter and more dry compared to the PX. A little too dry for my taste. Oloroso wins on the nose, PX does that on the palate. No clear favourite but I'm leaning a little more to the PX. A 50/50 blend actually works very well! All in all two good whiskies at their respectable ages, with subtle differences.
In your face sweet sherry and.. Bourbon? Quite woody indeed. Fruit and lots of sweetness upfront with dried apricot, orange zest, raisin, cherry and blueberry. Then white chocolate, custard, caramel, nougat and sugar cane. Further on vanilla, oak, roast almond and paprika. Tiger balm (or mint) and banana liqueur spring to mind too. Very wood driven, to the point I think about bourbon. And it's been a while since I've had any. Further on nothing faulty, just good sherry notes with a cooling mint/tigerbalm note that I like.
Mouth covering and with its high ABV pretty sharp. Very sweet and also dry like an oloroso. Fruits and sweetness play a big role once again. Orange, apple, apricot, blueberry, raisin and fig. After that caramel, dark chocolate, nougat and demerara sugar.
Also some roast almond, peanut, cinnamon, licorice, coffee and mint. A fierce and tasty one, not directly recognizable as a PX maturation although sweeter than most sherried whiskies. This can handle quite a splash of water without disintegrating. I liked it better after some drops.
Long and very drying. Assorted chocolate, orange marmalade, cookie dough and espresso.
