Comet was a cross of an English hop (Sunshine) and wild American variety in 1961 at Corvallis, Oregon at Oregon State University. First released in 1974.
Comet has gained more popularity over the past few years even though it has been around since the 60's. Commercial production basically ceased in the 80's for higher alpha varieties. Sometimes referred to as "Citra®'s Little Sister" as some prefer the lower alpha acid to Citra®.
