"[The brothers] bought three 5,000-liter oak vats for the Calcáreo Malbec range, and the 2018 Calcáreo Río de los Chacayes fermented in that cask and in concrete and then matured in the cask. The wine shows the stony soils with less limestone than Altamira or Gualtallary; it is elegant and fluid, and with the larger volume (and a longer élevage), the wines feel more elegant. 3,000 bottles were filled in February 2020. The vineyard is certified organic and biodynamic, but they don't show it on the label, as they want to do it and feel it but not use it as a commercial tool". - Luis Gutierrez.
