Abstract: The varietal, regional, yearly and type (red and white) effects on the degree Brix-alcohol relationship are discussed. It was determined that the degree Brix measurement by hydrometer is a relatively poor indicator of the expected alcohol due to type, regional, yearly and varietal effects. These effects are shown by regression analyses of a large number of varieties over a 3-year period, and by analyses of data of 18 varieties over a 9-year period. Type-region effects are very significant with the red varieties between the two regions discussed and between the red and white types.
