DMS, as well as the related compounds dimethyl disulfide (DMSD) and dimethyl trisulfide (DMST), can be found in [[Hops|hops ]] in small amounts. The amounts are generally considered so small that they voltilize volatilize off during the beer brewing process, however dry hopping has been shown to increase DMS in beer. One study found that lager beer that was dry hopped had 15 ppb more DMS on average. DMST can have a cooked vegetable, or onion-like aroma <ref name="Peppard_1981">[http://onlinelibrary.wiley.com/doi/10.1002/j.2050-0416.1981.tb04054.x/abstract VOLATILE ORGANOSULPHUR COMPOUNDS IN HOPS AND HOP OILS: A REVIEW.
