Tenuta Carretta is considered one of the most prestigious vineyards in Langhe-Roero and is comprised of about 65 hectares. The soils of the Roero are young and mostly sandstone, or sedimentary rocks derived from the compaction of marine sand. The interaction of the soil, microclimate, and vine varieties with the limited quantity of grapes produced per hectare gives unique characteristics to this area of wine. Sandy soils produce the most elegant and fragrant wines; and where the sand mixes with a more chalky base the wines become more austere. For Tenuta Carretta, recorded winemaking history dates back to 1467, making it the oldest winery in Piedmont. Today, the winery at Tenuta Carretta is part of a sophisticated wine tourism offer that includes Guided tours of vineyards and winery, A Michelin-starred restaurant, Ristorante 21.9, with Chef Flavio Costa at the winery, a restaurant and Locanda guest-house on the Cannubi hill in Barolo and a welcoming wine shop.
