1. Does it contain syrup?
Some beer will add syrup, aiming at improving the fermentation rate of beer, thus reducing the use of hops, which will affect the glycol degree of beer and make the taste worse, making it the lowest grade beer.
2. Do you have any rice or corn?
The only really good raw materials for beer brewing are malt, hops and water. In order to reduce costs and earn more profits, many manufacturers add starch accessories such as rice and corn to raw materials to reduce the proportion and concentration of malt in beer.
3. Look at the concentration of wort
The original wort concentration refers to the wort concentration reserved before beer fermentation, which is usually expressed by Baidu (P), not the alcohol content, but an index to measure the nutrition and taste of beer. The higher the concentration of wort, the higher the nutritional value of beer, which makes beer more foamed, better in taste and longer in shelf life.
Classification of ordinary beer:
1, Draft beer: Draft beer adopts special brewing technology, strictly controls microbial indicators, adopts three-stage filtration including 0.45 micron micropore filtration, and does not undergo thermal sterilization, thus maintaining high biological, abiotic and flavor stability of beer. This kind of beer is very fresh and delicious, with a shelf life of more than half a year.
2. Dry beer: beer has high fermentation, low residual sugar and high carbon dioxide content. So it has the characteristics of dry taste and strong lethality. Because of its low sugar content, it belongs to low-calorie beer.
3. Whole malt beer: brewing follows the German pure brewing method, all raw materials are malt, and no auxiliary materials are added. The beer produced has high cost and outstanding malt flavor.
4. Primary wort beer: that is, the filtered wort is directly fermented without adding the residual sugar from the second wort washing. It is characterized by mellow taste and clean aftertaste.
5. Dark beer: beer brewed by adding some burnt malt to malt raw materials. It has the characteristics of deep color, heavy bitterness, good foam and high alcohol content, and has caramel flavor.
