The first industrial-grade grain mill designed distinctly for homebrewing.

Its smoked cast acrylic body is equipped with three horizontally-ribbed stainless steel rollers, featuring dual-gap adjustment settings for reliable feeding and a consistently perfect crush.

Captain Crush is engineered using premium materials—aluminum and stainless steel prevent corrosion, oil-impregnated sintered bronze bushings require no maintenance, and stunning smoked cast acrylic body provides durability, visibility and easy cleanup.

The smoked cast acrylic provides a glimpse into the grain column, allowing you to watch as the grain cascades down the hopper, through the rollers and into the bucket. Better yet, the hopper and base require minimal assembly—simply bolt them onto the mill and you’re geared up to grind your grist.

Optimizing form and function, a raised rim on the underside of the base secures the Captain atop any standard 5 or 6.5 gallon bucket, and the hopper design distributes mass to achieve maximum stability without added weight. Horizontally ribbed rollers provide a more uniform particle size by synchronously feeding grain through the mill gap. And by crushing grain without piercing it, the slotted roller design can grind to a higher level of flouring without facilitating a stuck sparge. Dual gap adjustment enables maximal fine-tuning for a highly customizable, perfect crush and reliable lauter performance. Intuitive adjustment knobs feature hash marks to indicate distinct, repeatable gap settings while eliminating the need for feeler gauges in lining up the rollers. Dimples anchor the set screws in place to ensure a secure gap setting, and the drive shaft is equipped with three large flats to fit securely in the chuck of any 3/8” or larger electric drill.

Nothing but problems with this grain mill
Ever since I have had this grain mill, about 2 years, I have had problem after problem getting it to work. Even at the recommended gap setting I still get the rollers spinning without drawing grain into the mill. Once it gets going it will power through the grain but will soon stall out and free spin again. After contact with customer service at Midwest they sent me different set screws for the rollers, obviously this has been a problem in the past. Even with the new set screws I have the same issue over and over again. Even trying different settings this just does not consistently feed grain to crush. At this point I would buy any other mill on the market. Once I can save up, I will purchase another brand.While 2 years, estimated, may seem a long time to fight a grain mill, I normally do one batch every 2-3 months so it took me a while to use it enough that I felt it would be ok to write such a terrible review.

Response from Midwest Supplies
Thanks for the review, sorry to hear this one has given you trouble. Not sure what other trouble shooting tips we can offer - be sure to start the drill slowly and ramp it up once it starts feeding. It should be a high torque corded drill. Maybe we can get you a super discount on a new grain mill. If you want a good reliable mill that will just crush the grain and you do not have to fuss with, consider a 2 roller mill. Maybe we can swing like a 25% discount on a new grain mill if you are interested? Let us know if we can help!

Captain Crush Review
In short, do not buy. I purchased this mill as I thought I was buying a premium mill that would work with commercial reliability. From the start the mill would not properly feed grain…it was very temperamental at keeping rollers properly aligned without movement. I am an engineer and work on my own cars and airplane…I am very capable at diagnosing and repairing mechanical equipment. I have owned the unit for the past two years and have given up. Buy the cheaper two roller that may not grind as fast, but is reliable. All you need to do is crack the grain to mash…the object isn't to have precision flour milling.

It is great to be able to crush my grain bill at home. Captain Crush does great job.

It did take some time to get it setup. The instructions provided were poorly copied. I can't imagine not having a glossy instruction sheet that you could read would cost that much more.

I do love my Cptin Crush.

Customer service coming through
I cannot find how to edit my original review. Midwest is standing by their products, as always, and getting a replacement grain mill to me. I will further update with how that works. After talking to several people using them at Midwest I am hopeful.

Helps a lot
I like this grain mill a lot, I had a terrible thing happen I had hosed it out (being very old) when I tried to turn it over I dropped it broke the pieces off the base thought it was ruined I put it back together with epoxy and it works fine so far.
