Soil Diversity Flashcards
4 most common soil types in CdR
Clay
Galets
Calcareous
Sand
3 characteristics of different types of soil
water retention soil temperature, effect on wine
Clay soil qualities
high water retention
lower soil temperature
rich, colorful wines high in alcohol w/ powerful aromas, structured tannins
Galets soil qualities
high water drainage, retaining fewer nutrients, stressing the vine, leading to lower yields and concentrated flavor and structure
higher soil temperature
powerful wines high in alcohol, full body, ageing potential
Calcareous soil qualities
Chalky, limestone-rich soil stores just enough water to feed the vine during drought, but drains well
Cooler soil temperature, reflecting light up into canopy to aid ripening
High acidity, supple, light body, soft fruity/floral aromas
Sand soil qualities
looser texture drains easily, quickly; roots grow deeper
hold heat, but not as hot as darker, stonier soils
lighter wines with fresh, delicate aromas, lower tannins, elegant style overall
Large, rounded stones which radiate heat back up onto the vines at night and drain well, helping to concentrate the wines
Galets
Light-colored limestone stones which drains water well and stays cooler by not absorbing sunlight
Calcareous
Small, tightly packed particles that hold water very easily which keeps the vines cooler, allowing for slower ripening
Clay
Loosely textured, well-draining, and darker colored which *causes roots to grow deeper looking for water and retains heat in the soil
Sand
Soil type producing wines which are light, fresh, with delicate aromas, lower tannins
Sand
Soil type producing wines which are supple, with high acidity, light body, soft fruity and floral aromas
Calcareous
Soil type producing wines which are powerful, high in alcohol, full-bodied, and have ageing potential
Galets
Soil type producing wines which are rich and high in alcohol, with structured tannins and powerful aromas
Clay
