A good wine is all about balance

One of the most sought after wine concepts is that of balance. A balance in wine means that every aspect within it is in harmony, in tune. Meaning not one single aspect is more prominent than the other. Wine shouldn’t be too sweet or acidic, too many tannins or too strong. 
Each grape variety has its own characteristics. These qualities may be enhanced or weakened by the terroir (the climate’s influence on soil). As a result, monosort wine often loses its balance by lacking certain qualities, or on the contrary, having certain qualities that “stick out”. In order to balance out the wine, for example softening the acidity, correcting the aroma or enhancing the fruitiness – different grape varieties are mixed together. This is known as making an assemblage or blend (coupage).
