◌ Aroma

The nose opens with vibrant citrus notes—lemon zest and grapefruit skin predominate. Underneath sits a wave of tropical fruit character: mango, passionfruit, and pineapple from the blend of US hops. A clean, grainy undertone from the malted barley provides gentle backbone without obscuring the hop profile.

◐ Taste

Entry is crisp and refreshing, with citrus and stone fruit flavors establishing themselves immediately. The mid-palate sustains tropical notes while a balanced bitterness emerges—measured at 35 IBU, it sits comfortably between sweetness and bite. The finish is dry and clean, with no harsh edges.

Serve at 7–10°C

Cold enough to sharpen the hop aroma without numbing the palate. Around 7–9°C keeps the citrus and pine vivid without losing bitterness definition.

Pint glass

The classic — versatile, comfortable to hold and keeps the beer cool. No frills, no distractions: just the beer.

Drink fresh — hop aroma fades fast. Best within 3 months of canning or bottling.
