Why are some beers bitter, and what is the matter with beer

Why are some beers so bitter?

1.Use spoiled hops.

The bitterness in beer comes from hops, and the bitter substance in hops is commonly known as A-acid. If it encounters factors such as high water content, high ambient temperature, sunlight exposure, and poor packaging during storage, it will accelerate the oxidative polymerization of a-acid. The bitter substances in the hops are gradually oxidized and polymerized, turning into a hard resin with a very low bitterness.

Therefore, such a beer will have a post-bitter taste!

2.Excessive additives or improper methods of hopping.

If too much hops are added when brewing beer, the beer will be too bitter. At the same time, the addition method of hops is also very important, adding hops too early, the utilization rate of bitter substances is high, and the quality of bitterness is not very satisfactory; If hops are added too late, it will affect the utilization of bitter substances.

3.The alkalinity of the water in which the beer is brewed is too high.

Brewing beer with alkaline water dissolves more bitterness and gives the beer undesirable after-bitterness: Brewing beer with brewing water with higher bicarbonate not only affects the activity of enzymes, but also makes the hop bitterness coarse, resulting in post-bitterness and astringency.

4.Yeast undergoes autolysis.

If the external environment is unfavorable or the nutrients of the yeast are insufficient during yeast fermentation, the phenomenon of yeast autolysis will occur. It will cause the beer to produce bitter amino acids, and when its content is on the high side, it will give the beer an unpleasant after-bitterness.

In addition to the reasons shared above that will cause different degrees of bitterness in beer, there are many factors that will bring different degrees of bitterness to beer, such as insufficient wort boiling strength, excessive washing of wort grains, poor wort coagulation, poor fermentation, etc.

This is an awkward question, and in contrast, it should be asked why conventional industrial beer is so bitter because of its high wort concentration. Roasted malt can also be bitter. The amount of hops is large and I forget whether it is alpha or beta acid that is bitter, in short, it is the bitterness caused by hops.

There are also some flavor enhancers, coffee beans, cocoa beans, chocolate, malt, etc. As an aficionad, you will not lose sight of the aroma and balance of the wine because of bitterness.

The reason why <> beer is bitter is because a special plant called hops is added to the beer, and hops are also called hops in our country. This plant is one of the indispensable raw materials in brewing beer and plays a very important role. The bitter taste that hops bring to beer is also accepted and even perceived as a unique flavor.

Beer is bitter because the hops release an "alpha acid" during the brewing process, which makes the beer taste a little bitterer. Hops also play a very important role in beer, which can prevent beer from spoiling and has strong antiseptic properties.

At the same time, adding hops to the beer can balance the taste of the beer by blending the bitterness of the hops with the sweetness released by the malt. It makes the beer not too sweet and reduces the greasy taste. At the same time, hops in the beer can also make the overall color of the beer look more bright, giving people a more comfortable feeling, so that the beer does not appear very turbid.

Although beer may taste a little bitter, many people are the number one fan of beer, mainly because beer is clearly different from other alcoholic beverages.

First of all, beer is fermented and not high. For liquor, which is all fermented liquor, beer has a certain advantage. The degree is not as high as that of liquor, and being able to taste the aroma of malt can bring a relatively refreshing feeling to drink.

At the same time, the ** of beer is relatively close to the people, and many people can accept it. Beer is a very popular type of alcohol for people, and everyone can consume it. Moreover, the taste of beer is relatively refreshing, and in the process of chatting with friends, you can drink some beer to increase the atmosphere, and at the same time, it will not cause a feeling of drunkenness due to the high degree of beer.

Over time, beer has entered the public's field of vision because of its unique taste and people-friendly **. It has also become one of the most common alcoholic beverages in people's daily life, and has gradually formed a beer culture.

Causes of bitterness in beer:

1. There are hops in the beer, and the bitterness is mainly brought by hops, and the bitterness is also a major feature of beer. The beer tastes a little bitter, and I don't feel that way when I get used to it. If you don't know how to drink it, you can put a plum in it, so it tastes delicious.

2. Bitter mouth may be due to poor gallbladder function, especially a reaction of patients with gallbladder disease. Due to gastric infiltration and poor motility, bile reflux into the stomach can also cause bitterness. Therefore, you should go to the gastroenterology clinic for further diagnosis and **.

This is all related to personal taste, if you can accept this kind of wide mouth, you will find it delicious, and if you can't accept it, you will think it is difficult to drink. It's like someone who loves tomatoes, but someone who hates the taste of tomatoes. The bitterness of beer is an important characteristic that distinguishes it from other liquors, and the bitterness is mainly ** the hops of beer, which is produced by a plant called hops, which gives beer its bitterness.

In 1079, the Germans first added hops to brew beer to give it a refreshing bitter taste and aromatic smell, and then hops became the soul of beer, an indispensable raw material.

There is actually a standard for the bitterness of beer, and there is also an international bitterness unit called the International Bitterness Unit, or IBU for short. It is not about how bitter the beer is, but about defining the amount of a bitter element in the beer.

For example, 1 liter of beer contains 1mg of iso-acid, and the bitterness is 1 ibu. However, the higher the bitterness, it does not mean that the beer is more bitter, because the high amount of maltose contained in the beer can reduce the bitterness of the beer.

The bitterness of beer is not bitter like drinking Chinese medicine, and after drinking, the bitterness will disappear quickly, giving people a refreshing taste. The bitter taste of beer can be addictive, for example, when we drink coffee, we are not used to the bitter taste of coffee at first, but the more we drink it, the more bitter it becomes, and later we even drink only American coffee with no sugar and no milk.

Pure bitterness can make people get used to it, because the sense of taste can improve Qi Qinggao's tolerance for bitterness, and eventually even become addictive to bitterness. Bitterness has a strong neuromodulatory function, as the bitter taste slowly disappears from the mouth, the aftertaste is a kind of aftertaste, with sweetness, which can refresh the mind and relieve fatigue.

At the same time, the bitterness of hops and the aroma of malt are intertwined, which can make people happy, and even the more they drink, the more enjoyable they are, and Shen Ziyin can't extricate himself. Craft beer, the more bitter the score, the better the sales, people like to drink craft beer, drink it habitually, and then drink ordinary beer, it is simply impossible to eat. Ordinary beer, which we can call water beer, has a light taste and a bitter taste, but the bitter is not authentic.

Those who think that wine is delicious are not only referring to the taste of the wine itself, but also for other reasons. Some people are used to drinking alcohol, so they don't feel the taste of alcohol bitter.
