One, look at the material
Winemaking equipment is a tool for steaming wine, usually used to do winemaking equipment material, such as wood retort, iron, aluminum alloy, ceramic, copper, stainless steel, etc., the different materials directly affect the yield and quality of the wine taste, which material is the most suitable for us to do winemaking equipment, the following analysis of the different materials are as follows.
Wooden screening: the cost is cheap, but the wooden screening is a piece of boards put together, there are gaps between the boards, sealing is not good, coupled with the cooling performance of the sky pot is also poor leading to the wine vapors run outward, about 20% lower yield, cheap to buy expensive to use.
Iron: of course, the cost is also cheap, but iron is prone to rust, steam out of the wine is rusty, yellow color, affecting the quality of white wine taste.
Aluminum alloy: will not rust, not high temperature. Aluminum alloy contains lead elements, in the process of steaming wine is decomposed, affecting the quality of white wine, contains carcinogenic substances, the national food hygiene law, can not use aluminum alloy to make food utensils.
Ceramics: Using ceramics to steam wine, the taste of wine is OK, but the thermal conductivity of ceramics is slow, steaming wine for a long time, wasting fuel. And not easy to move and fragile, but also cheap to buy expensive to use.
Copper, there are copper ions can enhance the quality of white wine, is the best winemaking equipment materials, but the cost is expensive, a small equipment to tens of thousands of dollars.
Stainless steel: industrial, food-specific, medical steel, usually food-specific is 8K304 steel, acid, alkali, high temperature. Life expectancy of up to 10 years, good thermal conductivity, cooling and sealing performance is also good, to ensure that the yield and quality of white wine, moderate cost, is the best choice for brewing equipment.
If you want to buy stainless steel brewing equipment, it is best to use stainless steel to identify the potion to detect whether it is 8K304 stainless steel material before buying.
