I have a 10 gallon keggle HERMS system and have had a hard time sparging lately.
Everything looks and acts normally during the mash. The grain bed is set, the wort is clear you can see the grain bed through the wort. When I start heating the mash up for mash out a large amount of grain starts floating on the surface. So much so that I can't see the actual grain bed. It's not the whole bed that raises up, but enough so that there's about a 1/4" floating bed. It makes it hard to gauge my water level so I can keep it about an inch above the bed.
I've pulled some of the floating grain out, thinking it had somehow made it through without being properly milled, the crush looked acceptable.
This doesn't seem to happen every time I brew, I'm still trying to document things so I can notice when it does and doesn't happen. Right now my gut tells me this happens when I use English malts. I've been brewing a ton of Bitter's lately and it seems to happen all the time now.
Does anyone else have this problem, or know of a solution?
