Jurassic basalt moraine flint alluvial magma: what are these words and what do they have to do with wine? The answers are here in this book. They are geological terms that reflect a bond between wine and the land. Understanding geology, however, is tricky. Geological concepts are obscure; processes can be imperceptibly slow, invisible, and unimaginably ancient. The terminology is formidable, such that even the names of common rocks carry an air of mystery. Geology is introduced plainly, starting with basic principles, all in the context of wine. The emphasis is on the kinds of processes that shape vineyards and on the minerals, rocks, and soils that host the vines. Geological words now commonly seen in wine writings are systematically explained. You will learn the stories behind some of the names, the human face of geology. The book also explores how the geology-wine connection manifests in the finished product and evaluates its importance, particularly in the contexts of minerality, terroir, and wine taste. The fact is that geology is increasingly being promoted in the world of wine; the aim here is to help it be properly understood.
