Author of Vineyards, Rocks & Soils, Professor Alex Maltman is an acknowledged expert on wine geology. I caught up with him from his home in Aberystwyth to talk about his life’s work. Our in-depth chat covered earthquakes, Welsh Seyval Blanc, different types of rocks, his definition of the French word terroir, the unseen factors that affect vinous aromas and flavours and why geology is so often misunderstood by people in the wine business.
To about Alex, have a look at the University of Aberystwyth's website.  You can also read some of his articles in the World of Fine Wine.
