John Richardson Introduces the Saccharometer to Brewing

In 1784, English brewer and writer John Richardson published Statical Estimates of the Materials of Brewing, in which he explained how brewers could use the saccharometer to measure the density and extract of wort quantitatively. Instead of relying only on taste, appearance, and customary practice, brewers could now compare the fermentable strength of different worts and judge the yield obtained from malt with much greater precision. Richardson’s work helped turn brewing measurement into a practical tool of everyday brewhouse management. The saccharometer gave brewers a clearer way to monitor mash efficiency, compare raw materials, and improve consistency, and it also became important in excise control and brewery accounting. It marked a major step in the movement from experience-based brewing toward a more scientific and standardized brewhouse.
