Puttonyos is a unit for the level of sugar in Hungarian Tokaji. It is traditionally measured by the number of hods of sweet botrytised or nobly rotted grapes added to a barrel of wine, but is now measured in grams of residual sugar. The puttony was actually the 25 kg basket or hod of Aszú grapes, and the more added to the barrel of wine, the sweeter the eventual wine. Measurement ranges from 3 to 6 Puttonyos. A Tokaji made entirely from Aszú grapes is not labeled using the Puttonyos system but is known as Eszencia.
