75% Merlot/25% Pignolo. The vines are planted on ponca, a compressed, flaky clay of marl and sandstone that is typical in this part of Friuli. They grow on a south-facing slope right by the winery; average around 30 years old; yield about 45 hl/ha; and are farmed organically and harvested by hand like all Radikon vineyards. The grapes are destemmed and spontaneously co-fermented in 25-hectoliter oak vats without the addition of yeasts, sulfur or temperature control. Maceration is 8-14 days with daily punchdowns. The wine is aged in 25-35-hectoliter botti for a year and bottled without fining or filtering and with a tiny amount of sulfur. "RS" is short for "Rosso Sasa", named for its creator, Sasa Radikon.
