In viticulture, colour plays an important role in various areas. This begins with the soil in the vineyard, 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 and is also very important in wine evaluation.
The colour of the soil provides information about its composition and has a considerable influence on growth and wine quality. For example, a reddish soil colour indicates iron content. This soil, known as Rotliegend or Terra Rossa, is particularly suitable for red wines. See a complete list under soil type.

The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
