Tittarelli produces wines from Mendoza, Argentina's premier wine region. The winery focuses on Bonarda and Tempranillo, varieties that thrive in Mendoza's high-altitude terroir and continental climate. Bonarda, a dark-skinned grape native to Argentina, forms the core of Tittarelli's portfolio—both in a standard bottling and a Reserva expression that sees extended aging. The Reserva Bonarda and its standard counterpart have been assessed by Wine Enthusiast, Wine Spectator, and Wine Advocate. A Reserva Tempranillo rounds out the lineup, showcasing the winery's commitment to both traditional Argentine varieties and Spanish classics adapted to the region. Mendoza's elevation and diurnal temperature swings produce wines with ripe fruit character and structural definition, qualities evident across Tittarelli's range.
