Sandier than 86% of California appellations and clayier than 24%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 9% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
