Ageing is a fundamental stage in winemaking, during which gradual exposure to oxygen contributes to the development of the wine's aromas, flavours and structure. The size of the cask plays an important role in this process: larger vessels, such as balseiros, allow for slower ageing, preserving the wine's freshness and fruity character. Discover how coopers build a balseiro, a traditional craft that continues to play a vital role in the ageing of wines.
