The aromatic finish is notably long, evolving slowly and lingering in the air and on the palate with a clean, enduring expression that holds through the session. Even after consumption, the room retains a dense, fruit-forward trail that speaks to the cultivar’s aromatic persistence.secondary notes emerge, whispers of citrus rind, dried herbs, and faint incense that add complexity and dimension.
