Just reading up about issues with Dry Hopping if fermenting under pressure - the beer gushing with the sudden release of pressure from the vessel at fermentation temperatures. There's only so many foam positive compounds in the beer, so even if it doesn't gush out of the fermenter, perhaps this would have a negative impact on later head retention potential of the beer?
This got me thinking - would it be possible to integrate a ball valve into the ball lock kegmenter lid?
On the open-to-atmosphere end, the ball valve could have a PET thread.
The user could load dry hops into a small PET bottle, turn it upside down and screw it into the top of the ball valve.
Once tight, the user could then open the ball valve to allow the hops to drop into the fermenter with minimal pressure change, minimizing frothing, (PET could be flushed with CO2 for those worried about O2 pickup etc).
I think this would be a fantastic addition to the kegmenter lid!!
Thoughts from others, Kegland feedback?
Cheers,
Matt
