The author, a retired petroleum geologist, gives an exhaustive review of the French vineyards, paying special attention to the geology and soil compositions. Soils have to be well drained, and in most cases limy or marly soils give the best wines. The best soils for each grape variety are explained. The earth science presented is easy for geologists, but may at times be heavy for non-geologists. Fortunately, the author adds a lot of pictoresque facts on the history, culture and people behind the wines. After reading the book, one feels very much enriched and ready to enjoy even more France and its wines. Our taste buds only recognize sour, sweet, salt and bitter. Other tastes are in fact smells, the aromatics that are freed in the glass and mouth, and the subjective knowledge around the wine (but who wants to admit this !). The book is an excellent buy.
