A fourth IPA variety, the 75 Minute IPA, was developed in 2008, and is currently 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 further 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.
