Pot distillation is the use of direct fire heating for two successive steps of distillation. That is, the first original liquor into a low alcohol, in the capacity of 150-500L pot to add the new fermentation of good raw wine, has been heated and steamed until the steam contains a small amount of alcohol until, about 8 hours or more, the distillate (i.e., crude distillation of the original brandy) alcoholic degree of 24-32% (v/v). Take part of the end of the wine to separate the storage, the pot empty, and then into the new original wine and the last distillation of the end of the wine, the second distillation. In the same way, the third distillation is carried out. The main distillate from the three distillations will be combined and re-distilled, the re-distillation time should be longer, about 14 hours, but also to be divided into 1-2% of the head or part of the tail, the main distillate of the average alcoholic strength of 58-60% (v/v),
that is, for the original brandy. The original brandy wine will be blended and mixed, then after storage and a series of post-processing treatment, and finally bottled and shipped.
Secondly, grape skins or grape pomace are used as raw materials to make brandy. The pomace in the barrel, the container closed, so that the fermentation, because the pomace itself with yeast, you can not add another yeast. When the container is full, close the mouth tightly and leave an air hole at the top to allow carbon dioxide gas to escape. Fermentation time generally takes 10-15 days, the temperature is suitable, only
7-8
days. Once fermentation is complete, it can be put into a still for distillation in the same way as above.
