The Brewing Basics
Various brewing methods have been around since the 6th millenium BC, and there is no danger of this long standing beverage making process going out of style since beer is a favorite in every country in the world. The basics of brewing haven’t changed significantly since those early days of development either, except for the fact that stainless tanks, that is to say stainless steel tanks, are now usually used to store beer rather than the wooden caskets of ages past. There are many reasons for this shift, which can be explained while also explaining the bare bones of the brewing process.
The first step in a brewing process, when being done completely from scratch, is the malting process, which soaks the grains in a stainless tank, because stainless steel is completely sanitary and there is no risk that the grains will be compromised while soaking within its confines. The rest of the malting process involves drying out the grains for an extended period of time before moving on to the milling process, which cracks the grains open so the starches within will be more accessible during the next phase. Mashing, which is the step that turns the grains into sugars that can be fermented, also happens in stainless steel tanks for sanitary reasons. Stainless tanks are also preferred because mashing requires very hot water, and the stainless steel can stand these high temperatures without altering at all. The next few steps in the brewing process also involve high temperatures and the liquid being in a secure tank like a stainless steel vat. In essence, most of the beer brewing process is done within tanks that need to withstand high temperatures and hold liquid that is changing its chemical body constantly without affecting the liquid at all or letting any of it leak out. That is also why stainless tanks are preferred, because they are so strong and able to be built without leakable seams.
