Description:	Deficit irrigation is used to control grapevine vegetative vigor and the grape composition can be influenced by soil water content. The minerals contained in the grapes are responsible for the physicochemical properties and stability of the wine. Therefore, the aim of this work was to evaluate the effects of irrigation strategies on the properties of ?Syrah? wines produced in São Francisco Valley, Brazil. The irrigation treatments used were FI (full irrigation), RDI (regulated deficit irrigation), and DI (deficit irrigation). Winemaking was performed by traditional methods, followed by stabilization and bottling. Density, alcohol content, pH, total and volatile acidity, total and free sulfur dioxide, total polyphenols index, color intensity, and total anthocyanin content were determined, as well as the contents of Ca, Mg, P, K, Na, Mn, Fe, Cu, Zn, Cd, Cr, Ni, and Pb. The properties of wines were influenced by irrigation strategies, except for the content of total anthocyanin, Mg, P, Na, Cu, and Mn. The contents of Cd, Cr, Fe, and Zn were similar in the vines. The wines demonstrated varied properties with different typicalities. Irrigation strategies can be recommended for different products, FI for young and cheap, and DI and RDI for aged and more expensive wines.
