Chapter 102 Easy to know whether beer is good or bad

When identifying the quality of beer, you need to consider its variety first, and then observe according to the following aspects, your identification will become very easy.

1. Color
There are three colors of beer, each of which has different degrees of depth, but the color of high-quality beer, no matter how deep or light, should be clean and eye-catching.In order to achieve clean and eye-catching, in addition to the factors of color itself, transparency is also required.We generally drink light-colored beer. At this time, light-colored beer should be preferred, and it should be light yellow or golden yellow.The dark color is mainly caused by poor raw materials or improper production.

2. Bubble
When good quality beer is poured into a cup, white and fine foam will rise immediately, and it rises high and disappears slowly. The foam can last for more than four to five minutes. After the foam dissipates, the quality of the foam still hanging on the wall of the cup is better .After the beer in the cup is drunk, the more foam material remains on the inner wall, the better the quality.The ones with no hanging cups and thick foam are inferior.In addition, it should be noted that the wine glass should not be greasy, because greasy has a strong defoaming effect.

3. Aroma
Different varieties of beer have different aromas.Light-colored beer requires prominent hop aroma, and those with obvious malt aroma and mellow aroma are preferred, while dark-colored beer requires strong malt aroma.Beer with stale, draft, and other off-flavors is of poor quality.

4. Transparency

Good-quality beer is clear and transparent, and there should be no turbidity or precipitation.On the contrary, it shows that the stability of beer is poor, mostly because of poor brewing process and production.At present, the shelf life of bottled beer on the market is generally 1 to 2 months, bottled draft beer is generally about 1 week, and bulk draft beer can only be stored for 3 days. The longer the period is exceeded, the worse the taste will become.If the beer is found to become cloudy, it is not suitable for drinking.

5. Taste
Taste it with your tongue. In addition to the aroma of malt and hops, the taste is refreshing. After drinking, you will have a mellow, round and soft feeling. The aftertaste is comfortable and pure, and the stimulation of carbon dioxide is excellent.Generally, light-colored beer focuses on refreshing and pleasant feeling, while dark-colored beer focuses on mellow taste.If the taste is flat or bitter, the aftertaste is astringent, the smell of yeast and other peculiar smells are inferior.
