For many people, a bronze distiller with metallic luster is one of the soul elements of whiskey. This is undoubtedly related to aesthetic but Whiskey Distillery Kit's real reason for the use of copper distillers from ancient times to the present? Why not use more stable stainless steel or aluminum distillers with the times?
In the scientific and objective attitude, first ask if it is, and then why. So is it all the Whisky Still made of copper? the answer is negative. Due to the limited material of early whiskey brewing, various materials with durability and ductation are used -such as ceramics and glass.
But the copper materials later lived up and quickly replaced them and became an ideal material. The reason is simple: the height of the copper material can easily shape it into the design of the design and mold; the heat transfer efficiency of copper is quite high; at the same time it is still resistant to corrosion. Nevertheless, the use of copper is indeed "old -fashioned", and the cost of copper is not low. At this time, the brewers are reminded that the brewers are constantly trying to update, cheaper, and more durable materials, such as stainless steel, which have been tested among American brewers.
However, the winemakers who used stainless steel as the distillers discovered the fact that it was crying: stainless steel materials gave the whiskey a sulfur flavor, and this taste was obviously not welcomed by consumers.
Relatively speaking, the "security" of copper materials in the taste of whiskey has been proven by history, and now the brewing person has proved its unknown benefits through experiments.
The characteristics of the copper enable it to have a chemical reaction in the inner wall of the distiller to clear the high volatile sulfur -containing compound (mainly the two -basis triangular sulfe ether, a olfactory substance, which will make the whiskey disperse the bad smell) In addition, it also helps the formation of essential substances, which is an important source of fruity aroma in whiskey.
In the process of continuous distillation, copper materials are also conducive to concentrating the unwanted compounds, improving distillation efficiency, and making the taste of whiskey more smooth. But don't think that the scope of copper is just the distillers, and the condenser is also inseparable from the copper -the mainstream worm tube condenser and the shell tube condenser are based on copper.
So what is the difference between insect tube condenser and shell tube condenser? Although the raw materials of the two are copper metals, due to the differences in internal structure, the shell tube condenser eventually contacted with whiskey original wine and reacts with more condensation than insect tube type. Therefore The liquid has the characteristics of light wine and smooth and mature taste. Correspondingly, there are fewer "intervention" of the liquor condenser for the condenser, and the wine body has more sulfur smell, "fleshy" and fruit aroma. And some manufacturers try to use stainless steel condenser in order to pursue a more unique and rough whisper. Of course, it is not difficult to imagine that when the copper and a large number of whiskey in the condenser react, the loss is inevitable.
In simple terms, copper becomes "thin". At this time, the corresponding parts can only be replaced, and this is also called "the sacrifice of copper" by the brewers, just as the Scottish people evaporate the oak barrels as "the share of the angel".
In summary, although copper materials are expensive, its excellent ductility, thermal conductivity, and the stability of historic identity have made copper materials an indispensable part of the traditional Whism Still. Golden whiskey flowing out of the golden distillery was given amber color by the oak barrel. This process is like a triple -in -one and is not moved by the outside world.
