A used hop rocket or hop gun lets microbreweries recirculate wort through a packed hop bed for intense aroma without harsh bitterness. Available in 304 or 316L stainless steel with sanitary tri-clamp fittings, these vessels handle 200 g to 2 kg per charge. Suitable for IPAs, pale ales, and dry-hopped styles, they improve extraction efficiency and reduce beer loss compared to traditional dry hopping methods.
