Beer Brewing Guide - KEG Fermentation

Green hosing

Green hosing means filling the green beer into a suitable secondary fermentation container, such as a KEG, after primary fermentation.

Green hosing should be done as "late" as possible so that the trub in the main fermentation container has enough time to sediment, which clarifies the green beer.

If you ferment under pressure, you can use the process to separate your green beer from the sedimented yeast. You can then adjust the desired carbon dioxide content in the beer later using forced carbonation. You can read more about this topic under the heading "Forced carbonation"!

Secondary fermentation in the KEG

Filling beer into KEGs after primary fermentation saves a lot of time and labour when cleaning, filling and corking bottles. It is also possible to work with sugar or food to add carbon dioxide to the beer. It is also possible to force carbonate the beer in the KEG by adding technical CO2.

If you fill your beer from a pressurised fermentation container, make sure that your KEG is pre-pressurised, i.e. has the same pressure as your fermentation container. Use a spunding valve to check the pressure! You can read more about this topic under the heading "Pressurising"!

Forced carbonation

To carbonate your beer without sugar or food, you can connect it to a CO2 source to pressurise the keg containing the beer. You will need a CO2 cylinder and a pressure reducer for this. The spunding pressure to be set depends on the temperature of the beer and the desired carbon dioxide content. The colder the beer, the less CO2 is required.

You can find calculators for determining the pressure online.

Pressurising

Beer is transferred from the fermentation vessel to the keg or from the keg to the keg using filling adapters and the addition of CO2. This process is suitable for hop tamping in the secondary fermentation keg, for example.

To pressurise a soda KEG, you need:

Two NC/ball lock connections to connect the beer line
A CO2 connection set for connecting the CO2 line
CO2 cylinder for CO2
A pressure reducer to adjust the CO2 pressure
A spunding valve for pressure control and blowing off
A food hose

Make sure that both containers have almost the same pressure to prevent foaming! To do this, pressurise the container to be filled with 0.1 bar less CO2 pressure than in the other container. Before pressurising, a bunging device must be connected to the drum to be filled, as otherwise too much pressure would build up there and the product flow would be interrupted.

Spundy

The Spundy from Keg King is a neat little gadget that works as well as any spunding valve on the market. With a low profile - just 4.5 cm tall - the Spundy doesn't take up much room in fermentation chambers or kegerators. Spundy provides brewers with the ability to set the pressure control simply by turning the black valve tip clockwise to increase pressure or counter clockwise to release. The built in pressure gauge lets brewers see exactly what pressure is being held from 0 to 30 PSI (2 Bar). Spundy's pressure gauge unscrews for easy cleaning and can even be used with a pre-set PRV (pressure relief valve). Replacing the valve tip with a PRV gives brewers the advantage of preselecting the pressure they want to hold before there is pressure present.
