In the area of Rimini, those who love the "wine growing archaeology" can distinguish various dyeing grapes in the wrecks of some old vines. These grapes often don't have a specific variety name but they are identified with some generic names, which refer to their strong dyeing power. In the vine-growing and wine-producing areas, the dyeing grapes used to play an important role as complementary vines to refine the quality of red wines. The wise vine-growers, who knew how the season trend impacts on the level of sugar and colour of the red grapes, used to mix a certain amount of dyeing grapes in the vineyards. This stratagem allowed them to balance the scarcely coloured grapes during the bad seasons and to keep a young colour in the wines made of grapes that have the tendency to get darker prematurely. The grapes in the pictures represent the dyeing vines most commonly grown in the area of Rimini. The varieties shown at point 1 and 2 are very similar to the "colorini" grown also in Tuscany; the vine at point 3 is rare and only few samples have been found in a 60-year-vineyard in San Teodoro di Mondaino. It seems to have many similarities with another "colorino" from Tuscany, which is called "Colorino Americano". The dyeing grapes from our territory certainly deserve to regain their importance and some oenological tests should be carried out to check the stability of the colour with the passing of time, the dyeing intensity and the organoleptic characteristics that can be used to refine the wine blends.
