I always think in terms of extremes when “theorizing”.

Imagine two mash tuns with 25 pounds of grain for an 11 gallon batch.

One is a rectangular mash tun 5 feet wide, 2 feet from front to back and 1 foot deep…with a manifold running the perimeter of the bottom and crossing every 6 inches or so, front to back.

The other is a round mash tun, only 15 inches across and 7 feet high…with a square manifold fitting the bottom of the cooler. (Like I said…think “extreme”)

Both have more than enough room to accommodate the grains and strike/sparge water.

It just seems unlikely to me that the deep, dense, narrow grain bed of the round tun will allow the sugar to release and flow as freely as the larger, shallower tun. I have to believe there is some correlation between grain bed depth/density, and efficiency.

All things being equal, the only way I can prove this is to go buy a large rectangular cooler and to one of my normal (albeit phenomenal ) recipes…keeping all other process the same.

One thing that I *am* going to try is fashioning a copper manifold to replace the SS braid I've been using. I've got some copper tubing (pipe, actually, not the bendy-stuff) left over from when I re-did my chiller. I'll buy some elbows, some Ts, and fashion something up, see if there's any improvement at all.

Don't I look like the kind of guy who loves to solder copper pipe together?

I won't do that until after the next batch... a simple pale/amber ale to act as a control.

You batch sparging, or fly, BM?

I batch sparge...and don't solder those joints. A dry fit is all you want and they'll hold plenty tight.

Welding makes it more work than it needs to be and nearly impossible to clean the thing out.

I've never had my manifold so much as budge once dry fit together. Remember to cut plenty of slits and keep them on the down side.

You just like dropping hot solder on your naked “what nots”.

You act like I'm the only person who solders sans pants!

£150 for the Barley Crusher is crazy - with the current exchange rate that's almost three times what the 7 lb version costs in the US. I guess international postage to send a mill across t'Atlantic would be around $40, so the cheapest way to pick up a grain mill would probably be to get it posted direct from the US. Got any distant rellies in the States?

Bird…what kind of mash tun do you use?
I know I'm not near as experienced as either of you but I don't think the rubbermaid is the problem. I'm getting 80% with the Barley Crusher and my 5gal rubbermaid. I have done several beers with between 12 and 12.5# of grain, so the grain bed takes up better than half the depth of the cooler.
I have a short SS braid in the cooler and do two batch sparges with 175F water.

The Barley Crusher really made a difference for me.

I pulled the trigger on a 7 pound Barley Crusher today and I'm quite excited about it.

I choose the Barley Crusher for the following reasons:

1.) I hate companies that change hands. I've been screwed too many times by web hosts being bought or merged to feel comfortable with either a Monster Mill or a Crank and Stein.

2.) BierMuncher's "Customer Service" post - it doesn't get much better than that.

I choose the 7 pound hopper because I have a small apartment.

Are any of these mills adjustable enough to make flour, if you wanted to? SWMBO may be more likely to let me buy a mill, if I tell her we can use it to make bread.
