I really love having this diffusion arm instead of the hose I had before that just sat on the grain bed. I get a more even coverage over the grain bed now which has brought up my efficiency considerably, in-turn now I use less malt & I can buy more items from NORCAL Brewing Solutions.

Got this for my Spike Kettle. Perfect companion for HERMS and a lot better than hose on top of grain!
