The 2021 Vigneti Repetto "Quadro" Derthona is a stellar, chiseled expression of 100% Timorasso from its native clay-limestone soils in Sarezzano. Following Gian Paolo Repetto's "ancient method, modern technology" ethos, this cuvée is fermented in stainless steel and aged for 12 to 15 months on its lees, followed by extensive bottle cellaring before release. The 2021 vintage is showing fantastic vertical evolution, pairing a medium-to-full body with a piercing, nervous acidity reminiscent of a dry, high-end Riesling. The nose delivers precise aromas of crisp white pear, lemongrass, and green apple, layered with subtle white pepper and an underlying, smoky flint minerality. On the palate, it is linear and intensely savory, driving into a phenolic, textured mid-palate and a long, salty finish laced with hints of saffron and wild fennel. It is drinking beautifully right now but possesses the structure to age gracefully for another five to eight years.
