Link between H2S production and must nitrogen content revealed

Date or time period: 1979 Warning: Display title "Link between H<sub>2</sub>S production and must nitrogen content revealed" overrides earlier display title "Link between H2S production and must nitrogen content revealed". An inverse link between H2S production by fermentation yeast and must nitrogen content was clearly demonstrated and led to the wide-spread practice of adding inorganic nitrogen (e.g. diammonium phosphate) to control H2S occurrence in wine
