Catalyst

Tap to rate

Crisp and citrusy, with vibrant tropical notes and a touch of pine from Citra and Mosaic, a refreshing hop bite and a dry, clean finish. Brewed from barley and wheat malt, unfiltered, unfined and vegan-friendly, this is Atom's 5.4% American pale ale. Every Atom can carries a code: the central circle shrinks as ABV rises, and the denser the dots, the heavier the hopping.

◌ Aroma

The nose opens with bright citrus and tropical fruit notes, driven by the Citra and Mosaic hop blend.

The overall impression is fresh and inviting, with no yeast-derived cloudiness affecting the aromatic profile.

◐ Taste

Entry is clean and direct, with citrus and grapefruit flavors taking the lead across the palate. Mid-palate reveals a refined hop bitterness balanced by soft, slightly wheaty malt sweetness that prevents harshness. The 38 IBU bittering is assertive but measured, providing grip without dominating the fruit-forward character.
