In the process of aging wine, tannin, vanillin, oak lactone, eugenol and other compounds in the barrel will dissolve in the wine, which can make the wine more stable in color, softer in taste and more harmonious in flavor. In addition, the wall of solid wood wine barrel has permeability, which can improve the clarity of wine. In fact, the contribution of solid wood casks with different ages to wine is different. For wine, the beneficial ingredients and aroma in the old solid wood cask are much less than those in the new one. Generally speaking, solid wood casks can store wine for five to six years.
The surface of stainless steel solid wood wine barrel with inner liner is bright, easy to clean and free from dirt. It is safe, environment-friendly and sanitary. Tough, corrosion-resistant, combined with exquisite polishing technology, on the basis of practicality, it highlights beauty and elegance, and is easy to clean.
The manufacturing steps of solid wood wine barrel with stainless steel inner liner are as follows:
1、 First, the wood is cut into pieces. When cutting with a hacksaw, the growth rings and fibers of the wood itself will be destroyed. Therefore, in the manufacturing process, the wood must be chopped with an artificial axe and finely ground into a flat board, which is the basis for making the bulk wine barrel;
2、 For a long time, the wood should be dried. Oak chips must be placed outdoors before making. This process is mainly to increase the water resistance of oak and weaken the astringency of tannin;
3、 Put the oak pieces together. Cut the oak that has been dried into pieces that are wide in the middle and small at both ends. Generally, when making a barrel, 32 pieces of oak pieces are needed and fixed with iron bars;
4、 Is a crucial step on things like barrel heating and fumigation. By heating oak, the oak leaves a smoky flavor, which makes the soaked wine have almond and bread flavor;
5、 After the inspection is qualified, the wooden wine barrel can be artistic processed and put into the market.
