Keg at Brewdog Edinburgh. Pale amber, funky nose, light fruit, taste is tart, refreshing, dry toffee, soft passionfruit, sour finish.

Keg at Brewdog Birmingham; hazy amber put with thin white head, sour aroma, taste has tart fruits, sour with a feint hint of passion.

Keg at BrewDog Shep’s Bush - London. Pours mostly clear orane-gold with a quickly fading white foam head. Good lactic, sour fruits in the nose, some ripe berries. Light sweet flavor with quick, cutting citric bite, then some jammy and fruity sweetness, slight funk, fairly high acidity. Light bodied with fine, spritzy carbonation. Nicely lip-puckering to finish with a bit of tongue-blister, further jammy berries, clean citric tang. Solid.

Keg at BD Camden. It pours cloudy orange with a medium white head. The nose is fresh, fruity, passion fruit character, dried mango, earth and light lactic notes. The taste is crisp, tart, tangy passion fruit, lactic, fruit salad sweets, sherbet, zest and touch of acidity with a dry, mouth-pucker on the finish. Light+ body, moderate carbonation and slightly sticky mouth-feel. A straight-forward, yet very enjoyable sour. Refreshing and crushable.

Draught at Brewdog Bar Stockholm. Rather tart, almost acidic, for a Berliner wiesse but also lots of passionfruit.
