All of the grapes for Vina Echeverria Espumante come from ungrafted, selected clones of pre-phylloxera French rootstock. The grapes are hand picked and put in 18 kg boxes to be carried to the winery immediately after being cut. The wine is fermented in stainless steel tanks for 25 days at low temperatures and then blended and bottle for the second fermentation, which takes place in the bottle according to the traditional method. The wine rests in the bottle for almost 18 months in contact with its lees, before undergoing traditional riddling over two weeks before it is disgorged and corked.
