Description
A Brettanomyces bruxellensis isolated in Amsterdam: slow-growing, clean but distinctly funky. Use it for Orval-style bottle conditioning over a primary Saccharomyces beer, or alongside Lactobacillus and Pediococcus in a mixed-culture sour. Jasper publishes attenuation only as 80+% and does not publish an alcohol tolerance, so the attenuation ceiling here is representative rather than measured.
