Full review in a flight of six single grain: https://keinehalbendrinks.de/2022/08/24/single-grain-single-cask-teil-2/
Nuts, especially hazelnuts and also nougat. Plus marzipan and biscuits with vanilla. And also bright grapes on a stack of paper. That's a good start.
Raisins baked in biscuits. Bitter substances are added, especially coffee. There is also ginger, a pleasant and warming spiciness.
Sweet pastries in a bookstore. Plus old Calvados. I find it interesting that the bitter notes are even less in comparison to the taste. They are more of a citrus zest now.
