from Northern Brewer:
I’m seeing this is a sponsored post, but ditto the previous comment on the Williams system, the SS rod IMO makes a big difference
http://www.williamsbrewing.com/WILLIAMS-OXYGEN-AERATION-SYSTEM-P699.aspx is a better system with a SS rod instead of tubing, it makes it much easier to hold the micron filter at the bottom of the bucket and easier to use, for only a few bucks more. I’ve got one and love it, I’ve heard mixed reviews about the systems with all tubing. Thought I’d share!
