Terroir
or a way to make good
wines
The following division of these factors can be done:
- appropriate selection of grape variety
- area: exposition to sun, landform, soil type, division of zones
- climate: wind, humidity, temperature
- man activity: plant trimming, fertilization, cultivation system
According to a scientific theory hilly and mountainous areas give better grapes than plains. During the year a vineyard needs about 20 000 lux and the annual medium temperature should not be lower than 10°C, while the summer medium temperature is around 20°C and the winter around -1°C. The quality of wine also results from the soil on which grown vines. Without going into detail of geological features of give areas, it can be said that:
- sandy soil give delicate and soft wines with a light color and body
- calcareous soils give strong and very aromatic wines
- rocky soils give high quality wines of high alcohol level
- clayey soils give long-lived, full-bodied wines with high acidity
