winequality

A subset related to the white variant of the Portuguese "Vinho Verde" wine,
containing physicochemical information (<code>fixed.acidity</code>, <code>volatile.acidity</code>,
<code>citric.acid</code>, <code>residual.sugar</code>, <code>chlorides</code>, <code>free.sulfur.dioxide</code>,
<code>total.sulfur.dioxide</code> , <code>density</code>, <code>pH</code>, <code>sulphates</code> and <code>alcohol</code>)
and sensory (<code>quality</code>).
