Below you’ll find a constantly updating list of useful articles, books, and blog posts for brewing sour and funky beers.

The Mad Fermentationist
– Michael Tonsmeire’s blog is an absolute treasure trove of all things brewing, with a heavy focus on mixed and alternative fermentations. He now runs Sapwood Cellars with Scott Janish, the hop-head responsible for, another excellent blog. Tonsmeire’s book American Sour Beers (linked below) collates the best of his posts into an eminently readable guide to brewing sours.

Embrace the Funk
– Dedicated to ‘Sour, Funky, and Wild Beer’, this blog is an obvious place to start if looking to start alternative fermentations at home.


American Sour Beers – Michael Tonsmeire
– The entirety of this book is relevant and skillfully written.

Wild Brews – Jeff Sparrow
– As above. A seminal tome.

Farmhouse Ales – Phil Markowski
– Belgian Farmhouse Ales were once sour – intentionally or otherwise. Although this book does not specifically cover alternative microbes, it does provide a wonderful treatise on the saison style, with references to the historical role of mixed fermentation.

Brewing with Wheat – Stan Hieronymus
– Relevant primarily for its sections on Berliner Weisse and Gose.

Brew Like a Monk – Stan Hieronymus
– Useful for its segment on Orval, though overall an excellent read.
