Stainless steel inner liner solid wood barrel during the aging of wine, the compound substances such as tannin, vanillin, oak lactone and eugenol in the barrel will dissolve in the wine. These substances can make the wine more stable in color, softer in taste and more coordinated in aroma. In addition, the solid wood barrel wall can improve the clarity of wine because of its permeability. In the process of aging wine in stainless steel inner liner solid wood barrel, the above compounds will change over time. In fact, the contribution of solid wood barrel of different ages to wine is different. For wine, the beneficial ingredients and aroma contained in the old solid wood barrel are much less than those in the new solid wood barrel.

Stainless steel inner liner, solid wood barrel, bright surface, easy to clean, free of dirt, safe, environmental protection, sanitation and refinement. Tough, corrosion-resistant, combined with exquisite polishing technology, it highlights beauty and elegance on the basis of practicality, and is easy to clean.
Manufacturing steps of solid wood wine barrel with stainless steel liner:
In the next step, the removed wood is first cut into wood chips. When cutting with a hacksaw, most of the growth rings and fibers of the wood will be destroyed. Therefore, in the next manufacturing process, it must be cut with an artificial axe and finely ground into a flat surface wood plate, which is the basis for manufacturing bulk wine barrels;
The second step takes a long time to dry the wood. Oak chips must be placed outdoors before making. This process is mainly to increase the waterproof of oak and weaken the astringency of tannins;
Combine the oak pieces in three steps. Cut the dried oak into pieces with wide middle and small ends. Generally, 32 pieces of oak pieces are required when making a barrel, and fix the oak with iron bars;
The four steps are a crucial step, like barrel heating and fumigation. By heating the oak, the oak can leave a smoky taste, which will make the soaked wine have the aroma of almond and bread;
Five step inspection: put the lid on the bulk wine wooden wine barrel for sealing inspection. After passing the inspection, the bulk wine wooden wine barrel can be artistically processed and put into the market.
