Physicochemical tests and sensory quality scores for 6,497 Portuguese vinho verde wines.

About

Eleven physicochemical measurements (acidity, residual sugar, chlorides, sulphur dioxide, density, pH, sulphates, alcohol) for red and white variants of Portuguese vinho verde, each with a quality score from 0 to 10 given by wine experts. It works as either a regression or a classification problem; the classes are ordered and unbalanced, with far more average wines than excellent or poor ones.
