How about an explanation of your process and recipe?
I will note that all of my GF beers seem to ferment rather quietly; I've never had a blow-out, and rarely see much krausen. So that in and of itself is little reason to worry. I never use blow-off tubes, never ever ever. I don't know why these beers ferment so quietly, but they always do. 30 batches under my belt, and never have I needed a blow-off tube.
