A wonderful find was a little black book full of handwritten brewing notes in the archives of the Franciscans in Holland. The booklet dates from ca. 1840 and may have been used by someone connected to Franciscan monks in the region of Rotterdam. Dialect words, however, suggest the anonymous author was probably from Flanders, the Dutch-speaking part of Belgium. In any case, it contains one of the weirdest recipes Roel has seen so far. It provides a glimpse into the hidden world of brewing of the past.
