A Catharina Sour pours pale straw to gold, from clear to hazy and very fizzy, under a white head; fruit can tint both beer and foam. It tastes of fresh fruit first, which must be easy to name, with a clean lactic tartness behind it, a neutral or lightly bready malt and no hop bitterness to speak of. It is light in body and refreshing, at 4–5.5% alcohol. The fruit is often tropical, but need not be.

Where it comes from

Brazilian brewers made beers like it under other names, but the style took its name in 2015, when craft and home brewers defined it at a workshop in the state of Santa Catarina, with local fruit suited to a warm climate. It has spread across Brazil and South America, in breweries and in home-brewing competitions. Most brewers sour Pilsner malt and wheat in the kettle with lactobacillus, ferment with a neutral ale yeast and add fresh seasonal fruit late. The BJCP lists it as local style X4.

Next to its neighbours

It is close to a fruited Berliner Weisse, a little stronger and with more fruit, and cleaner than a gose, which takes salt and coriander.
