In 1889, John Montgomerie of Scotland filed a U.S. patent application titled "Making Malted Bread," which was granted in 1890. This patent asserted a prior patent existed in Great Britain dated 1886. Montgomerie claimed a novel saccharification process, which involved warming a portion of dough mixed with diastatic malt extract to an appropriate mash temperature and holding it for a time to allow the extract's enzymes to break down some of the starch into maltose.
