Solera process, the Ouroboros of the beer making. Neverending fermentation where once a year we take away half of matured beer, add fresh beer and let nature take its course. One day, almost 2 years ago, we discovered that one forgotten pilot brew has developed beautiful pellicle. We threw in a bunch of Brettanomyces strains, and we got house mix that keeps producing lovely red sours. We used it to start our own endless fermentation process.
