Possibly one for the more hop addicted of us......
Was reading the slides from the Aussie craft conference and saw that 48 hours dry hopping may be sufficient, but also that some kind of agitation / mixing greatly helps get some extra hoppy goodness going on.
Sounds as if there's some improvements available from just bunging in 2g per litre, beyond the obvious upgrade to 4g per litre.
So have been thinking about something ghetto like that could achieve the same. An 'external' torpedo could be good, but needs a pump and the torpedo itself, so what about something internal? Was thinking of something like a French press, but immersed in the fermenter, with a flapper valve top and bottom. 'Pumping' up and down would force the beer through the captive hops inside the 'press', and if fully immersed would have no oxygen exposure. Not sure if a sketch is needed? Or maybe a large mesh container with a gentle stirring paddle inside. Eventually this would evolve into something that would be thrown in on day 7 ish and left to run for 2-3 days before or during cc.
Obvious requirements:
Easily cleaned
Ideally use pellets not whole flowers as more varieties available for me that way. Flowers would mean that any screen can be a lot coarser though.
Can be put into the FV with minimum air/ oxygen being brought in with it. Believe pellets have advantage here, dried flowers full of air.
Some way of mixing/ stirring / agitating with the lid still on the FV, so a vertical drive shaft that can come up through small hole in top FV.
Eventually have this motorized, but for trials am happy to spend a few minutes a few times a day giving it a stir to see if it works.
So has anyone tried anything / seen similar contraptions? Will let you know how this gets on, but figured first stage was seeing if anyone had tried it before?
( I bottle, so keg hopping unfortunately not on the cards, yet)
