Effects Of Oxygen On Bottling And Kegging

By Cynthia Wood


Commercial brewers have measures to eliminate oxygen in finished beers. Home brewers should take the same caution. This gas has capability of affecting stability of your product. The flavor is also greatly affected. You should be careful of this when Bottling and Kegging locally. Just because it is homemade does not mean that its quality should be compromised.

Oxygen is harmless before fermentation takes place. At the first stages, brewers really need it. It is used for the proper growth of yeasts. These ingredients are normally placed in aerated spaces. Yeast growth determines the quality of final products. Over oxygenation is impossible. The process completely exhausts the air. Only pure oxygen remains after this. Air is good for proper expansion.

When fermentation of yeast begins, this gas is deemed a contaminant. Bear balls and party kegs with hand pumps compromise quality of beer. This gas spoils everything. These pumps destroy everything by directly pumping oxygen into the keg. Beer spoils within few hours. People are forced to consume kegs quickly to compensate. Use better equipment to preserve life of drinks.

Be careful because this gas can get into the final packages. Even small air gushes affect quality. Rapid destruction results. Even the flavor stability is affected. One cannot easily clarify the type of beer they are drinking. Oxygen has easy interaction with the tannins and the polyphenols. This causes chill hazes. A permanent haze results.

At the end of fermentation process, carbon dioxide sits above the beer. It is heavier than other gases. This air provides a protective cover to the fermenter. This layer can serve you to a great extent. The beer becomes better as it ages. In home brewing, it is easy to introduce air while transferring liquid from a vessel to the other. Excessive splashing, small leaks, pool seals or the kegging system can cause excessive oxygenation.

Find a good way to stop oxygenation. One of the strategies is avoidance of transfers. Transfer when necessary. Most brewers avoid going through secondary fermentations. The commercial fermenters will use conical fermenters. They get rid of yeast. There will be no need of transferring beer to vessels. Barriers. They will maintain quality of beer when it is stored. Glass and stainless fermenters can make good barriers. Plastics are permeable to air.

Avoid splashing during transfer. This is a big source of air. Use proper siphoning devices. Those with poor seals can pull air in the process. This manifests as bubbles near seals. Minimize splashing. Supply the container with carbon dioxide before sealing. Even in bottling, one should avoid splashing. Use bottle caps that absorb gas carefully make adjustments of the bottle cap.

Keen brewers make strides in their jobs. Oxygenation in the final stages should be highly avoided. Local brewers are also affected by dangerous bottle bombs. Use ingredients of high quality. Do not hurry bottling when the fermentation process is not over. Make use of high quality bottles. Make a thorough investigation before finally buying them. Beer should also be stored in cool places.
