The main cause of dizziness after drinking is alcohol, but the main causes of headache after drinking are the following chemicals: formaldehyde, nitrite, chemical clarification AIDS, heavy metals and other radioactive substances. These substances contained in low-cost beer are mainly artificially added to improve the stability (preservation) and clarify the beer. These chemicals can cause dry throat, headache, infertility and even cancer in the morning.
When China's top-quality beer just started to use processing AIDS such as PVPP, tannin and silica gel instead of formaldehyde in the final clarification process, German top-grade beer has already started to use microbial clarification process, far exceeding the realm of using any chemical substances.
As for the stability of beer, as far as the author is concerned, during his visit to Fort Elf and Imperial Winery in Germany, every working procedure, production equipment and workshop of the German beer production line were aseptic technological standards. German beer can be completely independent of the destructive sterilization method of finished product sterilization, but it can ensure the stability and sterility of beer at the source and in the process. Because of this, German beer has a longer shelf life, but it is fresher and purer because there is no high temperature and chemical sterilization. The components of beer are barley malt, hops, water (above 90%) and yeast. Anaerobic respiration: "Barley is germinated, heated, filtered, and then heated with hops to become concentrated beer liquid." The cooled concentrated solution is added with water and yeast and put into a fermentation bottle. In five to eight days, draught beer will be ready. " Finally, draught beer will be put into a bottle, which will take several weeks to fully ferment and mature. Hops can clarify beer, prolong the shelf life of beer and make it have typical bitterness and fragrance. The more hops are added, the more bitter the wine tastes. The thick foam on beer (which Germans call foam crown) is also the function of hops.
malt
Malt is the most important raw material of beer. The accurate definition of malt is: the dry matter of germinated wheat after baking. The malt used in German beer is different, and the personality of the brewed beer is very different. Malt varieties commonly used in German beer are light malt, black malt and wheat malt. High-grade German beer insists on using high-concentration wort and never reduces the cost by diluting the liquor, so it is full-bodied and full-bodied.

Hops are perennial vines, which endow hops with fragrance and bitterness. At first, people found this plant and added it to beer in order to balance the sweetness of wort. After scientific development, people found that hops actually have super health care function. Hops can naturally prevent corrosion, increase appetite, promote digestion and help sleep. It is precisely because of this that beer is used to appetize and sleep well before going to bed. The flavor of hops varies from place to place, and the taste of beer will also change because of hops. Most high-end German breweries, such as Fort Elf, use the finest hops made in Germany. Although slightly bitter, it has a strong fragrance of flowers and plants, which is more conducive to human health.
water
The quality of pure water is very important for beer. Water that is polluted or contains bacteria and impurities can never be used to brew beer. Furthermore, if the water quality is pure, contains proper amount of minerals, and the PH value is strictly controlled, delicious beer can be brewed. Water quality will also affect the flavor of beer. For example, there are mountain springs near German high-quality breweries such as Fort Elf and Emperor, and these breweries also have their own brands of mineral water. This natural and pure spring water alone costs 1 euro per liter in the German market. Is there a better choice to brew beer with it?
yeast
Beer yeast is a very safe, nutritious and balanced edible microorganism. Beer yeast contains almost no fat, starch and sugar, but it contains excellent protein, complete B vitamins, various biominerals and high-quality dietary fiber. Widely used in weight loss, diabetes, fatty liver, vitamin B deficiency and other health care fields.
