I have just bought a grain mill, nice 2 roller model from iBrew on the goldie. I did my first batch with it using a cordless drill to drive the mill roller.
My mash efficiency was down (~62%) on what I had previously (~70%), which I kind of expected as I thought it might take a bit of dialling in. I thought the grind looked ok, no photo though unfortunately. I made up the shortfall with some DME in the kettle so no dramas with the beer fortunately! The mill gap was around 1.35mm which is probably too high so I'm hoping changing this to around 1.0mm will sort out the efficiency issue but...
My question is - has anyone experienced a difference when a grain mill is power driven as compared to hand cranked? If so, are the recommended maximum speeds for a grain mill drive?
Cheers,
Adrian
