S.AF. hemel-en-aarde Clay predominant. Water holding capacity / Cover crops are used to reduce evaporation.
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.
METAMORPHIC SOILS Metamorphic soils have been transformed from another type of rock through heat and pressure over millions of years. SLATE SCHIST GNEISS
Teroldego Rotaliano DOC sandy and gravelly soils Outside the T-R DOC, cannot be bottled as Trentino DOC Can be bottled as Vini delle Dolomitti IGT
