Very useful pressure kegs as used by commercial breweries. Add max. 3 g/l sugar for second fermentation. With special re-usable rubber plug.
2nd fermentation in kegs
Most home brewers will want to do a 2nd fermentation in the keg to obtain natural carbonation just like in bottled beer.
The method is the same as for bottles: preferably dissolve the sugar in a small quantity of water or beer, pour it into the keg and transfer the beer in such a way that everything is mixed well.
Place the keg upright for several days at ambient temperature so that the 2nd fermentation can take place. Then put it in a cool place for clearing and maturing. A discarded but still working refrigerator is ideal, this allows you to pour your beer at the correct temperature.
When the beer has completely cleared, tapping can start.
