How do you keep a keg cold?

Answered by Phillip Nicastro

To keep a keg cold, one of the most effective methods is to use a keg tub. A keg tub is a large container specifically designed to hold a keg and keep it surrounded by ice. This creates an ice bath that helps maintain the temperature of the beer inside the keg.

When using a keg tub, it’s important to choose a container that is large enough to comfortably fit the keg and allow for the addition of ice. The tub should have a sturdy construction to support the weight of the keg and be insulated to prevent the ice from melting too quickly. Some keg tubs also come with a drain plug to easily remove the melted ice water.

To prepare the keg tub, start by ensuring it is clean and dry. This will help maintain the quality and taste of the beer. Place the keg inside the tub, making sure it fits snugly. If the keg is not filled to capacity, you can use additional insulation such as towels or foam inserts to reduce air space and preserve the cold temperature.

Next, fill the tub with ice cubes or crushed ice. It’s best to use a combination of both to ensure even cooling. The ice should completely surround the keg, reaching from the bottom to the top. This ensures that the entire keg is in contact with the ice, promoting efficient cooling.

Once the keg is surrounded by ice, you can add a layer of water on top of the ice to enhance the cooling effect. The water will further maintain the cold temperature and provide better insulation. However, be careful not to overfill the tub, as this may cause the water to overflow when the ice melts.

To keep the keg cold for an extended period, it’s important to regularly monitor the ice level and replenish it as needed. As the ice melts, it will gradually lose its cooling capacity, so adding fresh ice will help maintain the desired temperature. Additionally, keeping the keg tub in a shaded area or using a cover can help prevent direct sunlight and ambient heat from affecting the ice’s melting rate.

It’s worth noting that the duration for which a keg can stay cold in a tub will depend on various factors, including the initial temperature of the keg, the surrounding temperature, and the amount and quality of ice used. It’s always a good idea to monitor the temperature of the beer inside the keg using a thermometer and adjust accordingly.

Using a keg tub with an ice bath is an excellent way to keep a keg cold. By ensuring the keg is surrounded by ice and regularly replenishing the ice as it melts, you can enjoy chilled beer for an extended period. So, next time you’re hosting a party or gathering, consider using a keg tub to keep your beer perfectly chilled and refreshing for all your guests to enjoy.
