In viticulture, colour plays an important role in different areas. It starts with the vineyard soil, which influences the growth of the vines, and continues with the colour of the foliage and the colour of the grapes, which has a direct influence on the colour of the wine, which is also very important in wine evaluation.
The colour of the soil gives information about its condition with a considerable influence on growth and wine quality. For example, a reddish soil indicates iron content. This soil, known as Rotliegend or Terra Rossa, is particularly suitable for red wines. See a complete listing under soil type.
