Kafka's Dark Morphosis
By Rob Gallagher part of Recipe Index
BJCP 2021 Style 3D - Czech Dark lager
Tmavá piva in Czech Republic are quite a varied beast, with interpretations range from dry, bitter and roasted to soft, full and sweet. This recipe is towards the latter part of the spectrum, with a full malty richness and restrained roasted bitterness.
