ART+21 Pineapple and Passionfruit Sour Ale

ART+21 Pineapple and Passion fruit Sour Ale is a super sour, strong, light, refreshing and intensely exotic collab brew!


The Sour ale style includes quite a large selection of beers. This time we have decided to brew a beer similar to the sour wheat beer, Berliner Weisse. Ours is a much stronger version both in terms of extract and alcohol. The beer is acidified with lactic acid bacteria added to the brewing kettle. Its sourness is enhanced with pineapple and passion fruit puree.


With the extract of 15.2, quite high as for sour beers, we have saved a bit of sweetness to balance the exceptionally sour flavour produced by lactic bacteria and fruit. Oat and wheat flakes give the beer its smooth texture, haziness and high drinkability.


What defines this style are lactic acid bacteria, which produce the sour feel. Lactobacillus plantarum that can be found in bread starters, kephirs, or yoghurts, produce lactic acid which intensifies the sour flavour and adds to the beer’s refreshing qualities. This particular strain used in the process of acidifying in the boiling kettle adds some ethers that bring to mind apples or citrus fruit.

Extra ingredients:

Exceptionally aromatic but sour fruit: pineapple and passion fruit. Their aromas and flavours create an incredibly tasty and refreshing mix.
