The process of storing liquor in wooden barrels is a practice that aims to\udimprove the sensory characteristics, such as color, aroma and flavor, of the beverage. The\udquality of the liquor stored in these barrels depends on wood characteristics such as density,\udpermeability, chemical composition, anatomy, besides the wood heat treatment used\udto fabricate the barrels. Brazil has a great diversity of forests, mainly in the north, in the\udAmazon. This region is home to thousands of tree species, but is limited to the use of only\uda few native species to store liquors. The objective of this study was to determine some\udof the physical and chemical characteristics for four Amazon wood species. The results\udobtained in this study will be compared with others from woods that are traditionally\udused for liquor storage. The species studied were angelim-pedra (Hymenolobium petraeum\udDucke) cumarurana (Dipteryx polyphylla (Huber) Ducke), jatobá (Hymenaea courbaril L.) and\udlouro-vermelho (Nectandra rubra (Mez) CK Allen). The trees were collected from Precious\udWoods Amazon Company forest management area, in Silves, Amazonas. Analyzes such as:\udconcentration of extractives, lignin amount, percentage of minerals (ash) and tannin content,\uddensity, elemental analysis (CHNS-O) and thermal analysis were done. It was observed that\udthe chemical composition (lignin, holocellulose) and elemental analysis (percentage of C,\udH, N and O) of the woods have significant differences. The jatobá wood presented higher\udtannin content, and in the thermal analysis, was that which had the lowest mass loss
