Knocked up this wort aerator. The ones I've seen on the web use an in-line syringe filter in the air line. I decided to filter on the air intake. I've used :-
A tupperware box
The piece of the tube that used to house my hydrometer (until I smashed it)
The cap off the hydrometer tube drilled with little holes (stops the cotton wool air filters from being sucked into the tupperware box)
A couple of O-rings to hold the air intake in place
A dual fish tank aerator
A five metre airline hose so I could have two long hoses.
Food grade filler to seal it.
I stick two damp bits of cotton wool in the intake and run it for a while to ensure clean air is being pushed through before I use it. The non-return valves make it easy to detach the tubes for cleaning.
Built it because I was concerned I wasn't aerating enough.
Does it make a difference ? Don't know yet.
I used it on my recent porter brew and it created a nice foam on the top of the wort whilst it was running. I used it to mix the yeast in too (rather than hydrating).
As a test I've just made two DJs of red wine, one I shook the RGJ to aerate it as usual, the other I ran one of the aerators through it for 15 minutes. I'll be interested in how they progress.
