Control of hydrogen sulfide in beer with a copper electrolysis system 

Humans are very sensitive to hydrogen sulfide (H2S). Panelists may detect this off-flavor in beer at or below concentrations of 3 micrograms (ug) per L. Among the technological efforts to reduce H2S, the most effective approach is the dosing of minute amounts of copper ions into beer with the newly developed copper electrolysis system to precipitate it as copper sulfide. Exact control of copper treatment is crucial, since this ion has been implicated with beer staling. The traditional use of copper vessels, pipes, or copper plates does not allow such a precise control. The newly developed equipment can be installed into a beer line and consists of two unique copper electrodes. A specifically designed power supply provides the necessary voltage and current for the operation. In a typical application, the copper electrolysis system reduced H2S in beer from 3 ug/L to a nondetectable level, while the copper content only increased from 32 to 69 ug/L. The level of H2S in beer was determined by headspace gas chromatography. 

Steve Gonzalez started brewing professionally with the Sierra Nevada Brewing Company in 1995. Steve obtained an M.S. degree in brewing and distilling from Heriot-Watt University in 2001. Since then, Steve worked in various operations, quality assurance, research and development, and product development roles for breweries, distilleries, and wineries throughout California before ending up at Stone Brewing Company. ​
