◌ Aroma

The nose opens with vibrant raspberry and blackcurrant—bright berry fruit takes immediate prominence. Rhubarb's herbal-tart character peeks through the fruity layers, adding dimension without overshadowing the primary fruit expression. A whisper of underlying sourness invites the palate with refreshing promise.

◐ Taste

Entry is juicy and fruit-forward, with raspberry leading and blackcurrant providing deep berry resonance. Mid-palate introduces a pronounced but integrated sourness that balances the natural sweetness of the fruit adjuncts, while rhubarb's crisp, slightly astringent edge keeps the profile focused. The modest 10 IBU allows the fruit and acid to dominate, creating a refreshing interplay between tart and sweet.

The finish is dry and moderately short, with lingering tart and berry notes that fade cleanly. A gentle, refreshing sourness persists without sharp edges, leaving the palate cleansed and ready for the next sip.
