This episode is structured to support WSET Diploma D3 exam preparation for Castilla y León. It focuses on how altitude, continental climate, diurnal range, rainfall, soils, grape variety choice, and winemaking decisions directly shape wine style, quality, and price across Bierzo, Toro, Ribera del Duero, Rueda, and the Castilla y León VT. All content is drawn exclusively from the WSET D3 syllabus and is organized to reinforce cause-and-effect reasoning expected in distinction-level theory answers.
