Blow-Off Tube – Update!

Two days ago I pitched a hefeweizen that was notorious for vomiting through the airlock.  This time I used a blow-off tube.

Here’s an update showing how successful it was…

Fermentation is currently happening at a furious pace.  You can see that the collection bottle is full of krausen, which would otherwise have ruined an airlock.  Taping the hose down into the collection bottle was definitely a good idea – when I opened the door to take this photo it caused an eruption of activity.  Without the tape the hose would certainly be blown out of the bottle.

This technique seems to be delivering the goods – and will definitely be an addition to my arsenal.  In many respects I think I may move away from airlocks entirely for primary fermentation, and just use them for conditioning, dry-hopping, etc.
