To keg hard cider, you'll need a sanitized keg and a CO2 regulator. Start by transferring the cider from your fermenter or carboy to the keg. It's important to ensure that your keg is thoroughly cleaned and sanitized to prevent any contamination.
If you're doing an open-air transfer, make sure to purge the air out of the keg before transferring the cider. This can be done by connecting the gas line from your CO2 tank to the “gas in” post on the keg and slowly releasing the gas while the lid is slightly open. This will push out any remaining air and create a CO2 blanket to protect the cider from oxidation.
Once the cider is in the keg, it's time to carbonate it. Set your CO2 regulator to around 30 PSI (pounds per square inch) and connect it to the “gas in” post on the keg. This higher pressure will speed up the carbonation process. Place the keg in a cool location, such as a kegerator or refrigerator, and let it carbonate for 24 hours.
After 24 hours, it's time to adjust the carbonation level to your preference. Purge the CO2 out of the keg by pulling the release valve on the lid. This will remove any excess pressure in the keg. Then, set your CO2 regulator to your desired carbonation level, typically around 12 PSI for a moderate level of carbonation. If you prefer a more carbonated cider, you can set the pressure higher.
With the pressure adjusted, let the cider continue to carbonate in the kegerator for a few more days. The exact time will depend on your desired level of carbonation and the temperature of your kegerator. Keep in mind that colder temperatures will slow down the carbonation process, so if you're in a hurry, you may want to raise the temperature slightly.
During this carbonation period, it's a good idea to periodically check the carbonation level by pouring a small sample of cider. This will allow you to taste and assess the level of carbonation. If it's not to your liking, you can adjust the pressure accordingly.
Once the cider has reached your desired carbonation level, it's ready to be served! Connect your keg to a draft system or use a picnic tap if you don't have one. Make sure to chill your glasses beforehand to enhance the drinking experience.
Remember to always handle the keg with care, as it contains pressurized gas. Properly vent and release pressure before opening the keg to avoid any accidents.
Kegging your hard cider allows for easy serving and the ability to control carbonation levels. Plus, it eliminates the need for individual bottling and the potential for bottle conditioning issues. So sit back, pour yourself a glass of your homemade hard cider, and enjoy the fruits of your labor!
