Oak and spices in the taste. Burned oak - tickling the tongue. Raisins and vanilla biscuits. The finish is full of oak, but not overwhelming, and the sugary sweetness mixes great!
This just keeps getting better and better. So many flavours from the cask after all these years and the ABV is still very high. Do yourself the favour and play around with water, as the high ABV allows you to experience some changes. I will give this 88/100 (21/22/22/23).
