Encompassing eight hectares worth of 45- to 65-year-old vines, Cascina Luisin produces nervy, expressive, highly traditional wines from some of Barbaresco’s greatest sites—Asili and Rabajà among them. The winery employs low-impact farming, retaining grass and vegetation and employing only copper and sulfur to treat the vineyards, except in truly disastrous vintages such as 2002 and 2014. The wines ferment without added yeasts in old non-thermoregulated concrete vessels, with macerations lasting between 30 and 60 days (and sometimes as many as 90); aging is conducted in large Slavonian casks custom-built by the renowned Stockinger cooperage; sulfur is added only when the wines are racked, and bottling takes place without fining or filtration.
