4th Generation Winemaker
4th generation family winemaker Anthony Riboli received his M.S. in Viticulture from the University of California, Davis. During the 1997 harvest, he apprenticed under Michael Weis at Groth Vineyards and Winery in Napa Valley.
Since joining Riboli Family Wine Estates, his foremost goal has been the improvement of the quality of our wines through his meticulous focus in the vineyards. Major innovations include clonal selections, crop thinning, and deficit irrigation. One of his greatest pleasures is working beside his father and grandfather.
Arnaud Debons worked in the Bordeaux and Cahors regions of France after graduating from the prestigious winemaking program at the University of Toulouse. Looking for a change and a challenge, he moved to the U.S. where he worked as an assistant winemaker for Newton Vineyards in Napa Valley for several years before joining the Riboli Family at San Antonio Winery in 2003.
Arnaud brings constant energy and commitment to his job and particularly enjoys visits to the winery’s estate vineyards in Monterey, Paso Robles, and Napa Valley.
With more than 15 years of winemaking and management experience in Paso Robles at Rotta Winery and Eberle Winery, San Luis Obispo native Ben Mayo joins the San Antonio winemaking team in Paso Robles, focusing predominantly on the San Simeon, Maddalena, and Opaque brands of the Riboli Family Wine Estates portfolio.
Mayo was also heavily involved in the construction and management of Riboli Family Wine Estates’ new state-of-the-art winery, which opened in the Summer of 2016.
Lee Alegre was raised in Lodi, California and graduated from Cal Poly, San Luis Obispo in 1998 with a degree in Crop Science and specializes in estate vineyards in Paso Robles. He is passionate about growing the finest grapes in Paso Robles which shows in each of our estate vineyards. He planted both Stefano and Maddalena Vineyard and is currently replanting Pretty Penny and additional acres at Riboli Creston.
