Have a pretty big stout going crazy right now - woke up to the blowoff tube full, and the bucket lid was all distended upwards, about to pop. Released the pressure, cleaned and put the tube back, 15 minutes later the tube was full again. Gave up on the tube - removed the plastic bung from the bucket, covered it with some muslin soaked in starsan, and walked away. Hope I can get the tube back on before tonight.
