Note 173 — Chapter VII · New Process for the Manufacture of Beer.
Frank Faulkner translation
[The Balling saccharometer being almost unknown in England, we may explain that its indications are for percentages of sugar in saccharine solutions, or of extract in worts; 17·9° Balling, therefore, means 17·9 per cent. of sugar or extract in the respective liquids.—F. F.]
