A little knowledge about beer

1. Hops and cannabis belong to the same family
Hops, which is a plant like hop, first appeared as a dye and belong to the same family as cannabis, so hops can also treat menstrual pain. , Otherwise it will affect the flavor. However, in the hop field, how can we ensure that there are no seeds in the hops picked? Hops are a dioecious plant. You only need to ensure that only female hop plants exist in the plantation to ensure that no seeds appear. Therefore, as long as a male plant is found in a hop field, it will be immediately pulled out. Yes, the beer we drink comes from a female hop that has never seen an adult male in her life.

2. Where does the beer foam come from?
The main sources of beer foam are wort protein, yeast and hop residue. These beer raw materials will produce "foam protein" during the fermentation process, which is the key to the formation and maintenance of beer foam. When beer is fermented in the bottle, a large amount of carbon dioxide will be produced. When the bottle is opened, because the pressure is instantly reduced, a large amount of carbon dioxide will be separated from the beer, and foam will gush out.

3. The secret to pour the perfect beer
Choose a clean glass without oil and dirt. The cup should be slightly taller, so that there is enough space for beer and a little foam head. Tilt the beer glass at a 45-degree angle. Align the mouth of the beer container with a few centimeters above the midpoint of the glass so that the beer can be poured in the middle of the glass. Do not let the bottle touch the glass. If you are pouring wine for others, you should follow the etiquette to keep the glass as clean as possible. The bottle or jar may contain bacteria. Keep the pouring speed and the volume of the beer sufficiently uniform. During the operation, you should pour it down smoothly along one side of the glass, avoid splashing water, and aim at the center of the glass side. When pour one-third of the beer, you can put the cup flat for a while, then there will be about 4cm foam head, when it is a little stable, start to pour again. Please wait a few seconds for the foam to stay on top of the beer before drinking it. Smell the aroma at this time as quickly as possible, because when the foam reaches its peak, the aroma of beer is the strongest.

4. The reason why beer bottles are always brown or green
Light accelerates the production of riboflavin in beer, which is the main component of skunk fart. So the more light penetrates into the beer bottle, the more bitter and smelly the beer will be. This is also the reason why beer should be stored in a dark place and beer bottles are mostly dark. In order to avoid the influence of light to the greatest extent, most craft beer with high storage quality requirements choose to use brown wine bottles to filter light. However, the brown must be darker than the green, so why do green wine bottles still account for the majority? It turns out that in the middle of the 19th century, green glass was the cheapest and most common color, so people often used green glass bottles for beer, and this tradition was preserved.
Later, people discovered that brown has better storage capacity. So after World War II, brown bottles were in short supply. As a result, people began to use green glass bottles for beer. Therefore, people still regard green as a symbol of beer bottles.

5. Beer for monks
I believe many beer fans have heard of the monastery beer in the Middle Ages. Western religions believe that as servants of God, they should be self-reliant. Therefore, in the Middle Ages, monks in monasteries used the land given to them by God to raise livestock and grow crops, and use grains to make bread and brew wine.
Although it sounds very pleasant to be a monk and still drink beer, because the monastery has a month of fast every year. During this month, the monks cannot eat during the day or solid food at night. Beer is rich in nutrients. The monks use beer. Come as an energy source for Ramadan. According to historical records, in some monasteries, monks can drink up to five liters of beer per day. However, since you can drink five liters, you can also imagine that the alcohol content of beer was very low.

6. Flood caused by beer
Beer has been very popular in the UK since the Industrial Revolution in the 1970s. Because of its popularity, the sales volume of beer became higher and higher. The barrels used for wine were getting bigger and bigger. The largest wine tank manufactured by the brewery MEUX could hold the most. 600 tons of beer.
As a result, one day, the large wooden barrels stored in this winery were finally exploded because they could not withstand the pressure of the liquor, and a chain reaction was triggered-all the barrels of wine in the factory were exploded together, exceeding one million liters. The beer flood poured out, and 7 people were drowned. It took several weeks for people to smoke all the beer, and it took several months for the smell of beer to completely dissipate. This is the biggest disaster caused by beer since records.
