After pouring, it's young, spirity and almost like a grain and rye distillate: glue and spices that remind me of juniper. It's also a little metallic and sulfur driven. There is plenty of caramel too, and dried fruits.
Time heals, as often. The nose evolves towards a combo of sticky toffee, dried fruits (figs, plums), leather, and tobacco. In the background, I detect herbs and a little vanilla and still some metal.
With water, the leather and toffee become more dominant.
Initially sweet and hot, but the sweetness makes room for bitterness that almost gets out of bounds. It's mainly shows its notes of leather, tobacco and dried figs. After time the leather seems to be mixed with some stock tabs (maggi). There is a sourness that reminds me of balsamic vinagar.
In the beginning, the aftertaste is overwhelmingly hot and heavy, with a combination of sweet and sour, and later bitter and sour. It calms down with water, and is dominated by the leathery, meaty side and the acidity of the balsamic vinegar. To a lesser extent, I detect the figs.
