1, judging from the service level of the equipment manufacturer.
Pre-sale services include telephone communication, which is the first step to judge whether a manufacturer is professional or not, and the other is field trip. If a manufacturer refuses to let you go to the field trip, but orders directly on the website, then you can tell that this manufacturer is a poor manufacturer, because brewing is a very professional technology, and there are many things that cannot be clearly expressed in words.
2. From the after-sales service of manufacturers.
Inquire about the usage, equipment problems and technical problems of small brewing equipment on a regular basis. If there are any problems, the manufacturer can solve them.
3. Model of brewing equipment
The models mentioned here refer to the weight of a feed, ranging from small equipment to large winery equipment. If you brew white wine at home, the small brewing equipment is enough. If you want to run a winery at home, the home brewing equipment is ok. Of course, the winery equipment is suitable for friends who run wineries.
4. Material of brewing equipment
At present, the mainstream brewing equipment on the market is made of aluminum, stainless steel and copper. The brewing equipment made of aluminum alloy is forbidden by the state, and the brewed wine contains substances that are carcinogenic to human body. Neither aluminum nor aluminum alloy is desirable, and wine can't meet the standard for testing.
Brewing note:
1 Liquor brewing is also a process of microbial metabolism, and temperature control is very important for liquor production. If the fermentation temperature cannot be well controlled, it is inevitable to lose liquor, and it is more appropriate to control the fermentation temperature at 25-35℃.
2. It is a good method to reduce the alcohol content of liquor with pure water, and the essence of alcohol content reduction is a process of diluting various components in liquor body, so it will inevitably lead to the weakening of taste and aroma. Firstly, it is not recommended to reduce the alcohol content of liquor to too low, and secondly, the original liquor itself should be rich in aroma components, so that the water taste will not be heavy after the alcohol content reduction. It is suggested that an aging machine can be used in conjunction with the alcohol content reduction.
