IGNEOUS SOILS - CONCEPT AND EXAMPLES | cooling and solidification of magma or lava from within or without the Earth’s crust. intrusive or extrusive | Volcanic Granite |
extrusive soil formed from cooled, hardened, and weathered lava. | Volcanic soil | high proportions of iron, resulting in black- or red-colored earth, and is thought to sometimes impart an ashy, rusty taste to wines. |
Formed under the Earth’s crust by slowly cooling magma mixed with quartz | Granite | Its elevated pH promotes high acidity, and the rock is porous enough to create deep-rooted vines, producing layered, subtle, blossoming aromas and flavors that can develop for years. |
