Nose: apricots and chlorine. Apple juice. Sourly. A hint of coconut / bourbon barrel flavor, but barely any barrel wort noticeable. Below the ex-bourbon impression hovers a certain sherry depth away. But first: bright fruits, straw. Flowers, flower meadow. Lemons, possibly orange peel. Not easy, but: buttery, fat.
In the mouth: full, strong, good body, oily, slightly hot (rather alcohol / youth than the influence of the barrel). Starts sweet and sour, develops exactly in the direction, "juicy", and leaves in the finish exactly what you had already heard in the nose: Ex-Bourbon barrel flavors, again this chlorine note, floral aspects and light-fruited. Impression remains surprisingly long in the mouth. Long finish. At the second sip certainly coffee notes (sherry influence?) In the finish. But more barrel wort than originally suspected. Acid-spicy as an overall impression. The "Cask Strength" in young & sparkling (and maybe a bit sprightly).
With water in the nose even more "steamy" (more chlorine / ozone), surprisingly not even more fruits.
In the mouth then mineral, calcareous, milder, but also with a much less interesting finish.
