Ditch the knurled rollers! Mills that shred your grain to bits are old news. Our cutting edge slotted rollers keep husks intact while crushing kernels for the perfect grist, every time. And you’ll benefit from the superior crush until the end of time too, since slotted rollers never wear down.

Crush your cleanup--this non-corrosive mill can be hosed down and left to let dry. Plus, you’ll ensure you’ve got sparkling clean equipment next time you’re ready to use it. Wet mill at home for the first time ever, for no dust and no rust!

Mill uninterrupted, thanks to the huge hopper. Big enough for up to 11 lbs. of grain, you don’t have to stop your drill 10 times just to fill the hopper up. Dump it in, run it through and get straight to brewing!

Product Details

Make the most of your all grain brewing sytem with the perfect crush. Captain Crush® allows even more control over your recipes. Maximize extraction and efficiency for your specific brewery equipment.

As with all mills, use a corded electric drill for best results. While smaller drills may work, a strong electric drill (1/2" or 5/8") with a variable speed control will be able to start slow and provide the 175-200 rpm that is ideal for getting the perfect crush. Too fast and the grain will be pulverized or not pulled into the rollers at all.


  • 100% non-corrosive materials enable wet milling
  • Slotted rollers keep husks intact for better lautering performance
  • Dual-gap adjustments
  • Minimal assembly
  • Semi-transparent body so you can watch the mill work
  • Groove on underside secures mill atop any standard brewing bucket.
  • Drive shaft compatible with any 3/8" or larger electric drill.

Brewer's Note: Food-service grade silicone spray works wonders for ensuring smooth, consistent operation of Captain Crush®. It is safe, odor-free and keeps your rollers turning no matter how much grain you crush.

Worst Part of My Brew Day...
Bought this mill a little over a year ago and had some problems with it right from the start. Played around with the gap settings, tried silicone spray, and made sure the bolts were properly tightened with continued problems. Recently called NB customer service and tried all remaining recommendations with no luck. It'll take over an hour to crush grain for a typical 5 gallon batch as the rollers are constantly free spinning and require stopping, reversing, and frequent dumping of grain to clear the rollers. I've stopped using the mill altogether. It's faster for me to take my bulk grain to the local homebrew shop (25 min round trip) and grind it there. I'm usually very satisfied with NB products but I would recommend buying another brand.

Captain Crush or Captain Sucks?
I bought this mill awhile back and have only used it twice before it became totally useless. I used a low speed drill use on another cheaper mill that works fine. Not sure what this mill malfunction is. It just doesn't mill....at all. Not even sure how to fix it. The fact that I've used it twice and now it not longer works is a big disappointment. I would avoid purchasing this mill. Mills that are half the price are built better than this POS. :-)

Doesn't Stay Primed
We have been using the Monster Mill MM3 for about a year with no issue. It finally wore out, and figured we would try something new. We tried to use this mill for our small pilot system at our brewery, and couldn't get one good mill out of it. We used the MM3 on average of 3 times/week for our 3bbl system. The Captain Crush design is difficult to get primed, and several times during the milling process it would just stop milling. The non-powered rollers would stop turning, and it was very difficult to get them to grab the grain again. We tried every adjustment possible, including dampening the grain, which shouldn't be necessary. As much as I wanted to like this, stick with the Monster Mill.

Buyer beware
I crushed around 40 pounds of grain before starting to have problems with this mill; the roller that is in-line with my drill now free spins and does not mesh with the other rollers regardless of many hours spent cleaning, lightly lubricating, making gap adjustments, and adjusting my drill rpm. This product has a premium price tag for a less than premium performance and no warranty. This is potentially a very bad investment in expanding your brew equipment, I would suggest looking elsewhere.

Thoroughly Disappointed
I go into the local brew shop, they throw grains I buy there into their mill, turn it on, and out comes crushed grain. They do this all day long and their mill. The mill they use is also sold by Northern Brewer and is $100 less. So buying this I thought I was getting a Cadillac not an Edsel.I have done three batches and all the same. Grind about 1 to 1 ½ lbs. and then the mill free wheels. I have spent hours adjusting the wheels and no change. The crush I was doing today I finally pulled the whole thing apart twice. The second time I realized the non-powered top roller jams when I load grain and before I try to crush. I cleaned it out tried again and same result. I read on-line one little hint at the bottom of a reply by the brew-masters where the response said that mills like this are expected to be running prior to adding the grain. I then got the girl friend and had her run the drill and I poured in the grains. I was actually able to crush 10 lbs. in one shot. I have even bought a special drill that is high torque and low speed thinking that was the problem.The video I watched on the website shows a girl setting this mill up and then crushing a batch with it already loaded in the hopper before starting up. Why have a large hopper if you cannot load it up first. Unfortunately I was going to brew today but lost so much time messing with this mill I have to punt. May have to wait until next weekend and have to redo my yeast starter. I am praying next time I use it will work the way it did today with having it started first. Inconvenience as I have to have a second person to help but something I will overcome.Based on the reviews this is a consistent problem. I am sure I am not the only one thinking the extra $100 is going for a higher quality product. The only reason I am giving this product a 3 instead of a 1 or 2 is the quality of the wort I get from the mash using the crushed grains from this grill. Better results than any other all grain batches I have done.

Worst product ever
My wife bought the captain crush as a Christmas present last year and I finally got some free time to use it. The Captain Crush design is difficult to get primed, and several times during the milling process the rollers stop spinning which requires me to dump the grain and loose up the roller. They say this mill is corrosion-resistant but that is completely a lie. After my first wash and second time trying to fix it, I notice all three rollers had rust on them. The manual that comes with the Crush is incomplete. For anyone thinking of buying this product, I wouldn't do it. I would spend the extra dollars on the MMIII. I am very disappointed with this product and Northern Brewer for having 30 days returns on products that cost this much. There should be a 1 year warranty for product that cost this much. What a BIG POS. If I could give this product a zero, I would.

Captain Crush = terrible waste of time and money
The mill does not catch the grain. Simple as that. Spent hours to get this to crush grain. Works maybe 5% of the time. I wish I could get my money back on this. Terrible waste of money and time.

Response from Northern Brewer

We just spoke on the phone and I'm sorry again for all of the issues. I've emailed you the shipping label and we will get you the gift card as soon as the mill gets back here. Please let us know if you need anything else.

Very disappointed
When this mill works, it is awesome! Unfortunately that happens about 1 lb or less at a time, then it stops taking up grain and just spins! Then the grain has to be dumped and rollers moved to free up whatever grain is causing the rollers to stop spinning. I have had to completely disassemble it several times in the middle of a grind, just to try to finish my grain bill. Every brew day is a miserable headache until I get past milling grain. I bought this because it looked like the best consumer level product out there. Now I can't wait to replace it with something that actually works (and probably cheaper). I give it 1 star because 0 was not an option.

Very disappointed
Like the idea, the sturdy build of the mill and the three rollers. The first brew Captain Crush performed like a dream. Next weekend went to brew a 10 gal batch of Off the Topper. It was a nightmare. Took me over three hours to crush all the grain. Thought I had the problem fixed for my next batch after reading the Q&A and reviewing the you tube videos. Wrong! Took another three hours to crush about 15 lbs of grain. Similar situation for brew #4. Love to brew but dread the milling process now. Please save yourself the frustration and avoid this mill.

Worst Mill I Have Ever Owned
I received my first Captain Crush which had the thumb screws for adjustments. Despite using food grade lubricant and multiple adjustments, the mill absolutely would not work with a bottom stuck roller. I received a second Captain Crush and had almost immediate problems again. This one had obviously been used and returned. When contacting customer support, their suggestions was for me to take it apart and see if the springs were worn out. Yeah, $200+ for a grain mill, and I'm supposed to take it apart to figure out if it is going to work. Long and short, I did and replaced the springs. However, every brew day is an adventure. 45 minutes to an hour to crush grains, if you are lucky. It won't grab the grains, the roller adjustments suddenly become loose, you tighten them too tight, you loosen them up a little and they come loose. When it works, it does a great job, but it doesn't work more equally as often. This isn't my first grain mill and I'm beyond disappointed with customer service and the quality of the mill. I will do my best to never shop with Northern Brewer unless there is absolutely no where else to get a certain brewing supply that I need due to this $200+ waste of money.

Can this mill grind other grains like corn?
A shopper on May 31, 2017
BEST ANSWER: No, dried corn is very hard, and it can damage mills like this that are designed for use with barley, and other "softer" grains. Hard, dried corn can damage the bearings of any barley mill, so we'd never recommend attempting to mill dried corn in any of the mills we sell. A "Corona" mill would be able to do it.
Halfway through milling the mill starts freespinning and I have to reverse my drill and play around with it before it starts crushing again. I was just wondering why thays happening and how I can fix it.
N I on Sep 29, 2015
BEST ANSWER: What are your gap settings? Try widening the gap on the upper set of rollers to help draw in the grains. If you still want a finer crush you can have a smaller gap on the lower set. Also be careful not to run the drill at too high of an RPM. It may be that the reason it's about halfway through milling is because of the decreased weight of the grains pushing down into the mill. One other thing, is to make sure your gap settings are locked in and the knob is not moving. Tighten the spring loaded set screw on the knob/dial till you hear a click when it's turned. Hope one of these suggestions helps.
I have only used this mill twice since I bought it and it doesn't work. It doesn't mill. Looks like there is some type of issues with the rollers. Anyone ever run into to this issue and have tips on how to resolve?
J M on May 2, 2016
BEST ANSWER: I bought this mill for my nephew. He uses the mill all the time making all grain brews an works like a charm. He's never had any problems that I know of. He adjust the rollers to the change in size of grains,an how well he wants them milled. Works great.
I don't know what drill would be ideal for this mill. I currently have a cordless DeWalt 20V 450-1500rpm drill. I don't know if it has high enough torque to work well with this mill. Thanks
J U on Feb 13, 2016
BEST ANSWER: I just use a 18V Makita and put it on the low speed selection and it has plenty of torque; I generally do about 40 pounds at once.
I have used this crusher many times and I'm pleased with it. The only issue I had was not checking the set screws to make sure they were tight at the beginning. Today however, my grain crusher fell on the concrete floor and broke the hopper right off the body. Is there any way to order replacement parts for this crusher? I'm going to try 5minute epoxy to repair, hopefully it's strong enough to do the job.
A shopper on Jul 31, 2017
BEST ANSWER: We would be able to help out with parts, but we'd need to do an order on the phone, there's nothing set up online. But we can help out with this, if the gluing job is not enough!
Good day, tell me whether this send the mill to Russia ? and what is the price of delivery in Volgograd

I keep getting whole kernels that slip through the gap between the plastic housing and the rollers. The rollers seem to have some lateral play and can shift side to side, even when properly locked into their gap settings. I can clearly see them slipping through on the sides while crushing and find them in my grist. Am I doing something wrong? I totally disassembled and re-assembled the housing but seem to have the same problem.
F R on Apr 1, 2016
BEST ANSWER: A little bit of lateral play on the rollers is acceptable and normal for any mill. That shouldn't be related to grain getting through between the rollers and the acrylic side, though. Do you think you could reach out to us directly at brewmaster@northernbrewer.com? Wit a bit more information, I think we can figure out what is going on.
Q: In the product description it mentions using food grade silicone as a lubricant. I assume a spray can is meant. Where does the silicone get applied for best results?
A:It's definitely optional. The mill typically operates fine without any lubricant. The bronze bushings can be lubricated if you wish. Gabe from NB
Q: Yes, but I'm struggling with mine. Do I spray the silicone on the roller side of the bushing or from outside the box, or both sides of the bushings?
G F on Dec 4, 2015
BEST ANSWER: We would recommend spraying it on the outside. You could spray it on the roller side as well, but you would want to rinse the inside before running grain through it.

How can I order replacement parts??? Bushings on the drive roller are completely shot after
C H on Sep 28, 2015
BEST ANSWER: For replacement parts

you need to call customer service. Those are pressed into the housing so you would need new side plates. That should not be the case though. Refer to troubleshooting resources

calls customer service

consider some lubricant

but set up issues are the main challenge to easy crushing.
Has anyone come up with a reliable solution to the free spinning roller issue? I still have a couple hundred pounds of grain to grind and can't just up and buy a new grain mil due to the poor engineering this one was given.
