Established in 1859, Gaja is a family-owned winery in Italy. Giovanni Gaja founded this winery, and his great-grandson, Angelo Gaja runs the estate today. The family produces grapes in the 250 acres of vineyards it owns in Italy's popular wine region, Piedmont. This estate is located exactly in the districts of Barbaresco and Barolo.

In 1994, this family-owned estate became the proud owner of the Pieve Santa Restituta estate in Tuscany's Montalcino area. This 40-acre estate in Tuscany is dedicated to growing Sangiovese varietals. In the next year, Gaja acquired its second Tuscan Wine Estate called Ca'Marcanda in Bolgheri. This significant estate stretches to 150 acres, and is dedicated to growing many international grape varietals, such as Cabernet Sauvignon, Merlot, Cabernet Franc and Syrah.
