bottle conditioned) The longer hops are boiled, the more hop isomerization takes place, and the more bitterness is imparted to the beer. The 60 Minute is described by the company as "a session IPA brewed with Warrior, Amarillo and Simcoe" and rated at 60 IBUs. Dogfish Head introduced a device in 2003 jokingly called Randall the Enamel Animal, an "organoleptic hop transducer module" which "Randallizes" a given beer by passing the beer through a large plastic tube filled with a flavor enhancer, often raw hops, though adaptations such as fruits and coffee beans amongst others have also been used. The alcohol in the beer lifts oils off the raw hops and imparts even more hop flavor and aroma to beers that were already hoppy to begin with. The 75 Minute IPA was developed in 2008, and has been produced in very limited quantities, and typically distributed to vendors in firkins. The beer—nicknamed "Johnny Cask" and featuring a mascot resembling a young Johnny Cash tapping a firkin with a mallet—is made from a mixture of the 60 and 90 Minutes IPAs, and undergoes a separate cask conditioning which includes the addition of maple syrup. As a variation on the 75 Minute IPA, the Alehouse 75 is also available. It is a mixture of the 60 and 90 Minute offerings, yet is served in a standard Sankey-style keg, rather than a firkin. Ancient Ales In the late 90s, Dogfish Head started an "Ancient Ales" series, in which beer recipes were created based upon the chemical analysis of residue found on pottery and drinking vessels from various archaeological sites. These beers have been produced in collaboration with molecular archaeologist Dr. Pat McGovern of the University of Pennsylvania. As of 2010, four such brews have been crafted, and only one (Midas Touch) is produced year-round. The others are produced on a limited basis. Midas Touch Golden Elixir (first released in 1999). A strong ale based on residue found on drinking vessels from the tomb of King Midas, dating back to the 8th century BC. Defining ingredients include Muscat grapes, honey, and saffron. (See section below for more information.) Chateau Jiahu (first released in 2006). A spiced strong ale based on residue from pottery found in the Neolithic village of Jiahu (in central China), dating to the 7th millennium BC. Some defining ingredients include rice flakes, wildflower honey, hawthorn fruit, and Chrysanthemum flowers. As of
