Fermentation has many faces, in the truest sense of the word, because countless microorganisms are at work in the various processes used to produce beer or wine, as well as kombucha and other fermented beverages. Experienced craft beer brewer Bo Rino Christiansen has taken advantage of these exciting transformations and adds special yeasts to his herbal extracts. Before too much alcohol is produced, however, the process is interrupted, resulting in aromatically balanced, complex beverages with a fine perlage. This has already convinced the renowned restaurant Noma in Copenhagen, and what is good for the Danish fine dining is just good enough for us.
