Draft at Lagerhuys. Aroma and flavor of puckering acidic sourness, fresh tart lime, subtle coconut, wheat, sour slightly juicy mandarine and a fruity sour finish. Very good.

American sour ale flavoured with lime, mandarin and coconut, bomber shared at De Koffer in Groningen. Snow white, loose and open, bubbly head on a misty straw blonde beer with somewhat khaki tinge. Aroma of strong lime juice indeed, wet straw, green mandarins, gypsum, coconut in an old dry way rather than the fresh coconut I was hoping for – and much more subtle than expected, crushed green gooseberries, sourdough. Crisp, very sour onset, fizzy carbonation accentuating the acidity even more, with very puckering effect – the beer’s natural sourness working together with the citric sourness of the lime and mandarin, no doubt; clean and slender white-bready malt base completely dried by ongoing sourness with a clear citrus flesh aspect (lime) and a somewhat ‘soapy’ character I think needs to be ascribed to the mandarin, which gives a ‘green’ and unripe impression here. Citric acidity and lactic sourness combined make for a strong acid burn in the end, with chalky and fruity notes lingering as well as a very dim, faraway earthy hop bitterish touch which vanishes again as quickly as it came. Quite vinegary in the end, with the coconut remaining remarkably vague, though certainly noticeable. Typical harsh acidic U.S. style sour, a bit too harshly so even for me; it was the mention of coconut that attracted me to this bottle, but even that element remained a bit understated, alas (probably due to age - I'm sure this aspect is much more prominent in a fresh sample...).
