4hw.com.cn: Generally speaking, there are differences in taste, appearance and Nutrition between draft beer and cooked beer. Which is better to drink? Let's have a look!
The difference between draft beer and cooked beer
1. Packing method
Draft beer is usually in bulk. Due to the short shelf life of draft beer, which is only 2-3 days, it is not suitable for long-distance transportation. Generally, it is locally brewed wine, so many of them are bottled. And cooked beer is the most exposed beer in our daily life, which is usually bottled or tinned. However, with the development of technology, a part of bottled draft beer has come into our life.
Pay attention to two special situations:
(1) Draft beer is a kind of draft beer. Draft beer belongs to draft beer, but it is different from ordinary draft beer. It is processed by special equipment. It uses totally enclosed stainless steel barrel, transported by refrigerated truck. In the process of drinking, use draft beer machine to fill carbon dioxide, and control the alcohol at 3-8 degrees. It is directly hit into the glass by draft beer machine, avoiding the contact between beer and air.
(2) Draft beer is also draft beer. Pure draft beer belongs to draft beer, but it is different from ordinary draft beer. After special processing, the shelf life of draft beer can be extended to 180 days, which overcomes the disadvantage of short shelf life of draft beer. Now many manufacturers produce draft beer. The price of draft beer is generally higher than that of draft beer.
2. Taste and flavor
The taste of the draft beer is more fresh and fresh. The mature beer is the beer that has been sterilized at high temperature, while the draft beer has a less sterilization procedure and retains the original taste of the beer. The taste of the draft beer is better than that of the mature beer. Generally, the taste of the draft beer is more fresh. Moreover, because draft beers have a short shelf life and are usually just brewed, they are relatively fresh.
3. Sterilization method
After brewing, in order to prevent the beer from deteriorating in the process of transportation, the beer will be treated with high temperature to kill the yeast and miscellaneous bacteria, which is the mature beer. However, draft beer is not sterilized, and there are active yeasts in the wine, which is draft beer.
4. Nutritional components
Draft beer retains the activity of enzyme, which is beneficial to the decomposition of macromolecular substances. Draft beer is rich in amino acids and soluble proteins, and has better nutrition. The cooked beer loses some nutrients in the process of high temperature heating.
5. Appearance color
Draft beer has lighter color, better clarity, transparency and brighter appearance. The color of cooked beer is darker.
6. Shelf life
Due to the high temperature sterilization treatment, the shelf life of mature beer is also greatly extended. Generally, mature beer can be preserved for more than one year after being sealed. However, draft beer is not sterilized at high temperature, and its shelf life is usually only 3 days. It is usually made and sold on the spot. Once there is a smell of water and acid, it means that it has gone bad and can't be drunk.
Which is better, draft or cooked
Whether it is draft beer or mature beer, they have the functions of quenching thirst, relieving summer heat, beautifying and beautifying, and they are the darling of drinks. Draft beer and mature beer are different kinds of beer, which will bring people different taste and nutrition.
In terms of nutrients, draft beer is more nutritious than mature beer, and its appearance, smell and taste are better than mature beer. Draft beer has lighter color, better clarity and transparency, brighter and more beautiful appearance; it retains the activity of enzyme, which is conducive to the decomposition of macromolecular substances; it contains more amino acids and soluble proteins, with better nutrition.
However, draft beer is not easy to preserve, and it will break in a few days. Mature beer has a longer shelf life and more convenient packaging than draft beer. It is more suitable for the current assembly line business model and provides conditions for long-distance transportation and sales of beer. We can say that the bottle beer with one-year shelf life and the can beer are mostly cooked beer.
How to save beer after opening
If the beer is not opened, it can be stored directly in the refrigerator or normal temperature, but if it is opened beer, you should pay attention to the storage method if you can't finish drinking it. It is suggested to finish the beer as soon as possible after the opening of the bottle. It is better not to drink the overnight beer. Because the raw materials of beer are malt and hops, which are polyphenols with strong activity. After long-term storage, it is easy to combine with protein, destroy the nutrition of beer, and make the liquor turbid and stale. Even if it tastes bad, it will become less pure. At the same time, the taste of beer will be increased and the foam will be reduced, and the carbon dioxide will also disappear.
Alternative bottle opening method can seal wine bottle
Beer also belongs to brewing wine. It is a carbon dioxide rich beverage brewed by yeast fermentation. Generally speaking, once the beer bottle cap is opened, it is difficult to restore to its original state, which leads to loose sealing and rapid volatilization of carbon dioxide in the wine, so many friends have a headache about how to preserve the remaining beer. However, some life experts are trying to use a key or screwdriver to gently pry off the bottle cap when opening the bottle. When the wine can not be drunk, the bottle cap is pressed into a square, and then pressed on the bottle mouth, so that the bottle can be firmly sealed.
Pour into plastic bottle for preservation
Pour beer into a drink bottle (not into a plastic bottle), because it's tightly sealed and airtight, so it can be put for a few more days.
Because of the release of carbon dioxide, the loss of alcohol and other flavor substances, and the oxidation in the air, the taste will become very poor, even if the beverage bottle is sealed, it can not solve this problem, and there is also the problem of microbial pollution after the bottle is opened.
Plug the bottle and put it into the refrigerator
Now the beer package is very small. When you open it, there are living yeasts in the fresh beer. In the case of high temperature, it is easy to be rancid and deteriorated. Therefore, the beer should be stored in a ventilated and dark place below 15 ℃ (the best temperature is about 0 ℃). This will maximize the retention of foam in beer.
After the beer is opened, if you want to drink it the next day, you can cover the bottle mouth with a paper towel or plastic bag, and then cover the original lid. Put it in the refrigerator. As long as there is no wind in the bottle. Or use cork stoppers to keep bottles tight, all of which ensure that the beer doesn't go bad for a day or two.
