Even though the factory currently utilizes the most modern technology, the Piedmontese cask construction method has not changed over time: meticulous wood selection, all natural seasoning, and a curvature running the entire length of the staves, meaning that they have the same thickness at the ends and at the height of the faucet hole.  This increases the casks strength over time and allows for the renewal of the inner surface by shavings the wood without reducing the stability of the stave­.  The bottom of the cask is concave in order to make them as resistant as possible from the Iiquid they will contain.  The heads are curved in two directions to support the pressure created when full without the use of cross boards.  This characteristic requires eliptical shaped grooves or crozes that only a craftsman with significant experience, tradition and skill of this profession is able to create. 



No colored lacquer is applied to the heads of the casks produced by the company in order to not impair the final inspection of this specific operation.  Whether the wood used comes from France (Allier & Nevers) or on request, Slavonia or East European countries the staves are created from quarter sawn trunks.  Crowns are not used since they come from the exterior of the trunk where the wood is young, rich in tannin and lacks aromatic compounds.  In addition, the staves made from these parts tend to twist with the obvious dangerous consequences.
