Everyone is right. That's Sierra Nevadas, they call it the Torpedo, and named the beer after it. Blichman sells a home brew scale one as Hop Rocket. Generic term is hopback.
Since this is used after boil & prior to chilling.... On a homebrew scale, are using a hopback and adding hops at flame-out ideally the same? Do you get more hop characteristics from a hopback than just simply adding hops at flame-out? Thanks.
