Hydrogen sulfide (H<sub>2</sub>S), or just "sulfide" is a microbe-derived off flavor. It is the most common of a group of fermentation products known as volatile sulfur compounds (VSCs). Sulfide aroma and flavor is often described as sulfurous like rotten eggs, "rhino farts", sewer, or volcanic gas. It is also sometimes called a "[[reductive]]" aroma because it is more likely to accumulate under low-oxygen conditions.<ref name="Jastrzembski"/> | Hydrogen sulfide (H<sub>2</sub>S), or just "sulfide" is a microbe-derived off flavor.
