The timber used at present is the Quercus Petraea and the Quercus Pedunculata species of oak which, mixed together in proportions perfected by us over two centuries of experience, guarantee a wonderful bouquet. We can also produce casks made from other kinds of timber like cherry (Prunus Avium e P. Cerasus), acacia (Robininia Pseudoacacia), ash (Fraxinum Excelsior), chestnut (Castanea Vesca ) and other on request.
Over a century’s experience as well as continual scientific research has led to a steady improvement of the quality standard of the wood used. The timber to verify the concentration of aromatic compounds (Total extract of “Elagitannini“, phenols, Aldehydes, “Lattoni”, Furani”, to name but a few) confirm the procedure is the right one.
We purchase the timber directly from the best European forest in Slavonia, Bosnia, France and Central Europe, where our experts choose only thebest part of the timber. In Conegliano the wood is selected by our expert craftsmen. Only the best wood which passes strict selection controls is chosen to be seasoned naturally while the wood that does not reach our standards is resold. Obviously the wood chosen must be top quality, without splits, traces of ring etc. because these would cause leakage and deformation.
Moreover, knots could be the starting point for infections and once in use, the casks would rot and give off an unpleasant smell and cause leakage.
The second fundamental stage in the selection of wood is the natural seasoning. This is known to be the only method which allows the wood to reach its perfect physical and chemical stabilisation, especially if it is oak which as colloidal sap. Physical, because if wood is dried artificially it swells when it comes into contract with a liquid, thus causing the cask to deform and burst. Chemical, because only atmospheric agents can degrade the sap and solubilise the hard tannins (a long chemical chain reaction) thus ensuring a sweet, aromatic discarge from the wood without a green or astringent after-taste.
Naturally seasoned wood cannot be bought commercially as it is necessary only for cask manufacture and not for other industries. It is therefore the job of the cask maker to carry out this seasoning on its own premises considering that 8 months per cm. of thickness are necessary to guarantee a continuous supply of naturally seasoned wood.
Our premises covering 14.000 mc (700 lorry loads), guarantees that all the wood used in the building of casks is the best quality and that it is naturally seasoned for at least 8 months per cm. of thickness.
