The pipe for the moonshine still or distillation column is made of high quality 99.9% copper, Germany. The high strength of the product is ensured by its manufacture using a special patented technology.
The surface of copper is an unfavorable environment for the development of legionella and other harmful bacteria. Since the overall level of sulfur compounds that affect the aromatics of distillates, when replacing a stainless steel with a copper one, ceteris paribus, is significantly reduced, grain and fruit drinks are better and tastier.
Sulfur compounds appear in Braga during its fermentation. They have those forms that a person perceives as the smell of a burnt match; putrid odors; aromas of boiled vegetables; aromas of fresh and/or sometimes slightly suffocated meat.
Also, in various sources, one can find remarks that copper promotes the oxidation of aldehydes, which reduces their amount in the product.
