COTA 45 is a small family winery owned by Ramiro Ibáñez Espinar and María Rosa Macías Peña. It was founded in 2012 and is located in Sanlúcar de Barrameda. Their wines are the result of a constant concern for exploring the environment, from viticulture, geology, history, the vineyards to the human factor that intertwines them. It immerses all these feeling in each bottle to transmit the identity of each small vineyard. It makes and bottles UBE, a white wine of Palomino variety aged under the flor (like the simple Manzanilla), Agostado, a wine from old varietals with oxidative ageing and Pandorga, naturally sweet wines (from varieties such as PX, Pajarete, Tintilla).
