I just wanted to put a post up stating for the record that I own a Corona Grail mill. I know, I know. Many folks knock this mill for many reasons: shreds grain instead of crush, poor adjustability, hand crank is not motorized.
Well, let it be known here to all that this mill works just fine for the budget brewer. I have used the mill as is, without modification for years (at least the last 7 years) and it performs just fine. I have used it for upwards of 25 plus pounds of grain before. I have it dialed in just fine, and I don’t require much tweaking of the milling plate. However, I have it setup so that with just a couple turns of the wing nuts I can easily increase or decrease the crush on the fly if necessary (which I only find required when I am using wheat malt).
Would I like a roller style mill with a motor? Sure. But I own a Corona mill and I make great beer with it. My standard efficiency is close to 80%. Someday I’ll upgrade, but until then I’ll save my money for malt and more critical stuff.
