This year, some of the barrels that we have acquired were in need of being "recleaned" inside.
As a norm, our estate refurbishes all of our barrels every 5-7 years by removing 3-5 mm of wood that has been consumed by the wine and that has given up its tannins and therefore does not have any more to give.
With this refurbishing, the barrel returns to its ability to yield tannins, not like a new barrel, but certainly at 70%.
After the work has been completed, the barrel is washed with water and potassium metabisulfite. And then it is filled with Brunello di Montalcino wine.
