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.

Consistently the Best!
A great all-grain brew begins with a solid, reliable crush. This mill is the easiest to adjust and is very solid. I bought a dedicated Dewalt corded drill that I leave hooked up to my mill. This mill and my Brewing Classic Styles book are awesome together. I built a 10-gallon all-grain cooler set-up this past winter and have two brews down with this mill so far. No regrets and would buy again, as it will last forever.

Nice adjust mill, clear plastic is a plus, not negative.
Hey just a quick review, got this when it was promoted with 20% off.It's a nice mill... I've worked in a Homebrew store, brewed forever, and am familiar with other products... Even owned a few other mills. The adjustment on crush is quick, the mill will do fine crushes without trouble or jamming. And the rollers grab grain so a geared drive isn't necessary to keep a feed going. As to the plastic... I actually like that the most; I can see when the bucket is full and there's a coolness factor like watching beer ferment in glass... You can see the crush happen. Newbies will love that. And I gotta say I like it too. The three roller gives a nice even crush, and yes if you frig with grinds and go real fine, you can get higher efficiencies (at the risk of a stuck mask and getting some husk in your boil). But hell, that's preference, Miller pulverizes it's malt with a hammer mill. They get 95 + efficiency by doing so. That's closer to mash filters than lauter tuns.I have a barley crusher too... (I have brew setup a in multiple states ... Haha) the barley crusher is great too. I don't care for wood though, gets a little musty and moldy if it gets wet. I'm lazy and hose off equipment to keep things clean and prefer plastic or metal; those materials dry without mold. Anyway the thumb screws don't appear to be a problem but will keep you all posted. All and all, slick mill with selling points for sure.

Improved Product. Easy Exchange. Great Customer Service
I bought the Captain Crush around late Nov 2014 and didn't get around to using it until Jan 2015. Despite applying food-grade lubricant to the bushings, the original unit had a bottom roller that wouldn't turn, and one of the top two was stubborn. I can't say for sure, but it seems like the old thumb knob adjustments for the roller spacing weren't great either. The new model features machine screws in place of the thumb knobs, better bushings, and an even more solid base. Small adjustments led to a big improvement on what was already a great design. I probably just got one of the early bad ones, which another reviewer said he experienced too.The customer service can't be topped. Just try the chat box or a phone call to see for yourself. Real brewers answer.

Customer Service
I did have a few issues with my Captain Crush. I couldnÕt get the rollers set. I worked with the Customer Service to do some troubleshooting, to which they gave me some great advice. Long story short; NB ended up sending me a replacement after having the initial mill for almost six months, FREE OF CHARGE!! I have to say the Customer Service alone is worth it on this product if you feel the price is too high. IÕve since received and cranked out about 50+lbs of grain through the new mill with zero issues. IÕm sure my initial mill was that one-in-a-thousand that just donÕt jell so well. Great product, Superb Customer Service!!

Solid Mill....Great Crush
I just received my Captain Crush a couple weeks ago and had a problem with assembly and cracked the base but NB customer support was terrific and send me a replacement out and I received it yesterday. After assembly I tried a sample crush and think this mill is winner... It is replacing my 3 year old Barley Crusher... and let me say there is NO comparison... the Captain Crush is in a different league. I was going to wait a bit to do a more in depth review, but I noticed that there is a 4 hour sale today and wanted this review to be seen by possible customers!!! At 20% off this mill is a STEAL..... IMHO. One note on assembly... make sure to assemble the base before the hopper.... if you do the hopper first it is very "tippy" when assembling the base. Also it should be noted that the flat washers should touch the Plexiglas and the split washers go in-between the flat washer and the head of the screw. In other words the split rings should not directly contact the Plexi.UPDATE: I have now brewed a batch of Pale Ale using the Captain crush and I am very impressed.... The milling fast and smooth. I always mash in at 1.5qt/lb to protect from thermal heat loss during mashing and generally spend a few minutes breaking up dough balls with my mash paddle and heavy duty whisk... but this is the first time I doughed in without 1 single dough ball or clump!!! Fly sparging went off without a hitch and I hit all my numbers, I did not see any increase in efficiency with the factory default settings. I'm perfectly fine with 75% mash efficiency. I am totally in love with this mill!!!

Well built, excellent performer
I purchased it when it was discounted by 20%. I was immediately impressed by the the mass of the roller assembly (over 5 kilos for the rollers/housing). It's easy to assemble, and it verges on being a monolith. The visible grain column is a nice perk. I've run 3 all-grain batches through it, and it's awesome. The roller gaps are easy to adjust, and they stay locked in position - no slipping. I crush my wheat malt, barley and specialty malts separately (adjusting the gaps for each malt), so I'm quite pleased with the simplicity/accuracy of the adjusters. The rollers move freely. The crush quality has been fantastic - most of the hull is intact, and I can adjust the final grind to a higher level of flouring without facilitating a stuck sparge. I've only had to use half of the rice hulls that I traditionally use in my Hefeweizen recipe. I highly recommend the Captain Crush. I'm getting an average efficiency of 85% with this mill. I've been brewing for about 18 years (17 years all-grain), and I'm quite pleased with my purchase.

Need to lubricate roller bearings to get reliable outstanding performance.
Love the Captain Crush mill. It has a high milling rate that provides perfect crushes. Bought mine the summer of 2014 for 6-12 gallon homebrew batches. I keep the mash tight and then do a 30 minute fly sparge using Beersmith sparge volumes and mash efficiency is always (last five batches) in the high nineties with no stuck mashes. I wet mill (1 oz of water to lb of grain) to get the best grind but I don't rinse the mill now. It has its issues which rinsing will make worse. The mill's set screws rusted and bearings gummed up when I rinsed it. Per NB recommendation, I cleaned up the mill and used a dap of mineral oil on the bearing surfaces. Also sometimes have to run mill in reverse for a second prior to milling in the proper direction to get it to feed sometimes. Its taken me about ten batches to dial in the crush and how to operate the mill. That said, this mill is fantastic and makes hitting your numbers a pleasure. I got several high gravity batches using kits that were suppose to come in at 1.06 OG. Love it!

Hated it but......
Ok, so I tried everything. Read the instructions, cleaned it well, set it right, and still the rollers would bind, usually right in the middle of several pounds of base malt! I was feeling pretty low after spending a butt-load of money on this thing to replace my simple (but actually working) grain mill. And then I had a thought. Food-service grade Haynes Silicone Spray. This sanitary silicone spray lube convinced the rollers that they wanted to keep turning. It imparts no odor, poisons or hydrocarbons and works like WD40 for beer-making. I now love my Captain Crush mill and take back ALL the bad things I said about it. Well built, smooth operation. Yes it is a little pricey but I now think it is worth the $$.

Works great cleans up easy
Title says it all, this mill gets the job done. From some of the reviews that I read online I was uncertain I made the right choice. But the mill was great and cleaning it was very easy.

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.
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 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.
