Hello everyone, I am Cameron Nelson and for this quarter I decided to test if you could achieve a lower carbonation output by changing your pouring style to a hard pour instead of a soft pour when pouring a beer. For reference a hard pour is poured quickly down the middle of the glass and a soft pour is down the side of the glass slowly the reason I decided to take on this task was because of a common issue amongst all beer drinkers. Feeling full and bloated after drinking a few beers. As we all know if you drink a beer with a soft pour right off the tap in a reasonable amount of time you will be bloated and feel full. this is due to the amount of carbonation that is left in the beer which is then consumed by you. After a few test trials and conversing with my peers I came to the conclusion that if you use a hard pour technique it will allow the beer to off gas more than the beer that was soft poured. Therefore, making the consumer feel less bloated and allowing them more room for beer or food.

After coming up with this theory, I decided to take it to the lab using the pilsner I brewed last quarter. after setting the pilsner to about 12 psi I gathered my supplies. I used a 500 mL graduated cylinder, a stir plate, an Erlenmeyer flask a rubber stopper with a rubber house connected through the stopper. I then filled a sink full of water and submerged my graduated cylinder in the water. After setting up the sink with the stir plate near buy I filled the flask using a soft pour technique and plugged it as fast as possible. I took the flask to the sink and picked up the graduated cylinder leaving the open end in the water and the lower end vertically out of the water allowing the water in the cylinder to stay. With the hose connected to the rubber stopper I funneled into the graduated cylinder and placed the flask on the stir plate. At this time, I started a timer to see how long it would take for the beer to completely off gas. I repeated the same process twice once with the soft pour and again with a hard pour. I tried doing everything as quick as possible to ensure accuracy.

The results were as expected with using 300 mL of beer for both test the soft pour released about 270 mL of gas and took 8 minutes to completely loose carbonation. and the hard pour released about 185 mL of gas and took 6 mins to do so. In conclusion If you use a hard pouring technique, you can save your stomach from a little gas therefor allowing you to not lose your appetite too quickly.
