Several years ago the folks at Dogfish Head created a device called Randall the Enamel Animal. It connects a keg faucet to a canister holding fresh hop cones. When the keg was attached to the Randall, the beer was pushed through the cones as it was poured, adding an intensely fresh hop aroma. These days, breweries and craft beer bars employ Randalls to infuse not just hops, but also fruits, spices, and coffee beans into their beers. Want to try it at home? All you needs is a French press.
