Hamburg is an apple cultivar described in South Dakota State University's historical bulletin A Study of Northwestern Apples. The bulletin says it came from seed of Fameuse and was raised by S. A. Alling of Homer, Minnesota. It interprets Hamburg's traits as evidence of a Fameuse x Plumb Cider cross, with Plumb Cider shape and Fameuse color. [S1]
The surviving description is short but useful. Hamburg is noted for snow white flesh, and the diagnostic list places it in the late winter season group. [S1]
No hardiness zone is given. Its inclusion in a northwestern apple bulletin from the South Dakota Agricultural Experiment Station places it in a northern prairie and northwestern comparison context. The packet does not include a specific winter survival statement for Hamburg. [S1]
The source treats Hamburg as a Malus domestica apple cultivar. The stated origin from Fameuse seed is direct evidence. The proposed Plumb Cider connection is an interpretation from observed traits, not a documented controlled pedigree. [S1]
