Tonic (drink) — a fresh, bitter-citrus note with sparkling and cool nuances. Its scent evokes fizzy tonic water, lemon peel, and a hint of quinine’s crisp bitterness. This note adds brightness, vibrancy, and a clean freshness to the fragrance. Tonic is often used in top notes, bringing an effervescent, invigorating energy reminiscent of a chilled gin and tonic — lively, clear, and refreshingly modern.
