Below there is a comparison between the Valchedor Cask and a normal barrel. In terms of the contribution of wood substances to the liquid contained, as well as the time of exhaustion and, therefore, useful life. The study conceptually represents the difference between the two barrels.
We start from the premise that a regular barrel has a quantity of wood extractives (ppm) to transfer of 100 units during its useful life. For this study we have chosen to use a Valchedor Cask with an extra contact surface of 500%, being an intermediate option, since we could reach percentages close to 800%. Therefore, the Valchedor Cask would have 500 units of wood extractives (ppm) to transfer during its useful life.
In terms of depletion and contribution, the barrels have a useful life of 8 years and an annual transfer of substances from wood of 50% compared to the previous year.
