The note bursts forth with an invigorating tang, a vibrant, effervescent sparkle that tickles the senses much like the carbonation of a fine brew. It possesses an initial sharp, almost vinegary zest, swiftly mellowing into a complex interplay of fermented fruitiness, often leaning towards tart green apple, ripe peach, or a subtle berry nuance, underpinned by the gentle, earthy bitterness of black or green tea. There's a delicate sweetness that emerges, preventing the acidity from becoming too stark, reminiscent of molasses or dried fruits. Its texture is inherently bubbly and airy, lending a refreshing lift to compositions. As a heart note, it offers a fascinating dynamic, providing both brightness and a grounding, slightly woody-tea character. It projects moderately, creating an aura of vitality, and its longevity allows it to bridge top notes of citrus or light florals with more substantial woody or musky bases, evolving from a crisp, lively opening to a softly lingering, nuanced tea-like whisper.
