I have been brewing the beer kits from Marcellos for awhile.
I ferment in a 6 gal. carboy and haven"t had a problem with
foam reaching the top of the carboy. Well I brewed a belgian ale
kit on a Sunday and the next day when I got home there was good yeast
activity. Later that night I checked on the batch and foam had reached the top and was going into the water trap. I swrilled the carboy around and the foam dropped down. Cleaned the trap. Later the same thing was happening. Swrilled the carboy and cleaned the trap, it was late so I went to bed and hoped for the best. Mistake! The trap clogged, pressure built up and the trap blew off. It made a considerable mess on the cabinets and a small mess on the ceiling. Wife was not happy!
Has anybody used fermcap and does work as advertised?
