I'm curious how popular the different aeration methods are. I personally shake up my bucket or carboy, but I don't think I do it enough or something. The gravity of my batches have been ending high and I'm wondering if it's a lack of O2. What do you do?
primary - Cider
Secondary - columbus pale
on tap - Arrogant bastard clone
i pump mine from the BK to the fermenter, and i do it full volume. It comes out like a fire hose. I aim it from 3" above the top to the opposite corner. By the time I get it up to 6 gals the foam is coming out the top. I call that good enough.
edit; before I pumpped I used to pour it back and forth from bottling bucket to fermenter about 4 times. Fu(k that heavy lifing garbage.
I ferment in buckets, so I lay a mesh strainer over the top and pour the wort through it from about chest height. When I do extract kits I do the same thing and also top off with the sink's spray hose. Usually creates a HUGE amount of foam on the top, plus the yeasties like it and usually take off pretty quickly.
i have this plastic aeration tip that makes the wort fan out. you attach the tip to the end of your tubing open the ball valve and let it go. i also do this over a strainer/colander so I can strain out hops and stuff at the same time. works great, wort is always very foamy when I'm done
