Wine Quality (Red)

Red wine samples tested for their chemical makeup and then scored by experts on quality. You get measurements like how much alcohol, acid, and sulfur dioxide are in each wine, plus the final quality rating it received. It's useful if you're curious about what makes wines taste better or want to build a system that predicts wine quality from lab results. This is popular with data scientists learning machine learning because it's small enough to work with quickly but has enough real variation to be interesting.
