How did Europeans come up with such a ridiculous thing? ! Pouring beer is a skill that requires knowledge. I remember a few days ago, while drinking with an old classmate, a classmate who had become quite famous said, \"This beer is too cold; let’s put it aside to warm up a bit before drinking it.\" For me, if the beer isn’t cold or pouring it isn’t fun, I won’t drink it at all. Beer contains carbon dioxide, which causes foam to form when it is poured. That’s why it’s common to see people, when pouring beer, either fail to fill the glass completely or have beer spill out, resulting in waste and an unsightly appearance. How to fill a glass with beer without any beer or foam leaking out? 1. Keep the beer in the refrigerator to be chilled thoroughly before opening it ； 2. Very slow beer pouring ； 3. Shake it well before opening the bottle cap ； 4. After opening the beer bottle, shake it gently first ； 5. When pouring beer, tilt the beer bottle appropriately and adjust the tilt of the glass accordingly ； 6. After opening the beer bottle cap, place it aside for a while ； 7. Don’t overthink it; just go with your feelings. When making a choice, please explain the reasons for it from the perspective of chemical engineering.
The fifth approach is the most reasonable: there should be no mixing, and air must enter the bottle smoothly.
I heard someone say at the night market that it refers to crooked, dishonest, despicable, and vulgar ways
1. Keep the beer in the refrigerator to be chilled thoroughly before opening it； Low temperature means more dissolved gases. 2. Pouring beer very slowly ； Stirring quickly helps; it facilitates the escape of dissolved gases. 5. When pouring beer, tilt the beer bottle appropriately and adjust the tilt of the glass as well ； Same as above. 6. After opening the beer bottle cap, place it aside for a while ； First, release pressure on your own; once the amount of dissolved gas decreases, the foam will naturally decrease as well
5. When pouring beer, tilt the beer bottle appropriately and adjust the tilt of the glass accordingly；

When I got the beer, I also chose option 5; I tilted the beer bottle appropriately and adjusted the tilt of the glass as well； When it’s time to pour the beer, place the bottle opening close to the rim of the glass, allowing the beer to flow slowly down the sides of the glass toward the bottom. As more beer fills the glass, gradually tilt the glass until it’s upright; this way, the glass can be filled to the brim without any foam forming. The reason for tilting the beer bottle is mainly to reduce the foam in the glass; this foam is formed by a supersaturated solution of carbon dioxide.
None of the answers are correct. Genius answer: Crooked paths, liquid flowing down the cup’s side
Generally, when pouring wine for a leader, it’s the fifth type that’s used; when pouring for oneself, it’s poured generously based on intuition
I don’t drink beer very often. From what I remember, fewer bubbles are formed when pouring from the side of the glass. As for the principle behind bubble formation, it’s due to gases escaping from the beer, combined with the surface properties of the beer liquid, which results in the creation of numerous bubbles. To reduce these bubbles, one can address these two factors: reducing the amount of gas that escapes by applying pressure or lowering the temperature; however, applying pressure is not practical； When the temperature drops, it doesn’t seem like there are fewer bubbles in chilled beer. To change the interfacial properties of a liquid, one should not add any defoamers first. I wonder whether such underhanded methods increase the surface area of the liquid; during the pouring process, most of the gas evaporates directly, or the liquid is too thin to allow bubbles to form easily. .
Despicable and vile; turn over a new leaf. Beer won’t produce lots of foam
