The idea of this Campo Demo is to test the effectiveness of biostimulant products that, applied on the leaves, could interact with the metabolism of the plant, favoring the concentration of solutes. If the results will be interesting enough, this solution could substitute or support the practice of "manual thinning" in order to increase the quality of the product while limiting the production costs. The targets will be qualitative traits, with the possibility of implementing microvinification. The analyses that will be conducted are:

• Maturation curve;
• Anthocyanins;
• Polyphenols;
• Maturation index;
• Tannins;
• Sugars;
• pH;
• Acidity.

The Grapevine biostimulants Campo Demo is a great opportunity offered to evaluate the effectiveness of different products.
