Captain Crush® Grain Mill

SKU: 41212
8 Review(s)

The Captain Crush® Grain Mill is engineered using premium materials; aluminum and stainless steel thwart corrosion, oil impregnated sintered bronze bushings require no maintenance, and smoked cast acrylic provides durability, easy cleanup, and dashing good looks.

The smoked cast acrylic lets you catch a glimpse into the inner workings, allowing you to watch the grain's voyage down the hopper, through the rollers, and into the bucket. Best of all, the hopper and base require minimal assembly - simply bolt them onto the mill, and you’re ready to grind them grains.

Optimizing form and function, a raised rim on the underside of the base secures the Captain snugly atop any standard 5 or 6.5 gallon bucket, and the hopper design distributes mass to achieve maximum stability without adding weight. Horizontally ribbed rollers provide a more uniform particle size by synchronously feeding grain through the mill. And by drawing grain through the mill without piercing it, this slotted design preserves the delicate grain husk to allow a finer crush than knurled rollers without sacrificing spargeability. Dual gap adjustment enables maximal fine tuning for a highly customizable, perfect crush and consistent 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 ⅜” or larger electric drill.

Hated it but...... Review by Robert
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 $$. (Posted on 10/24/14)
Customer Service Review by Michael
I did have a few issues with my Captain Crush. I couldn’t 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.

I’ve since received and cranked out about 50+lbs of grain through the new mill with zero issues. I’m sure my initial mill was that one-in-a-thousand that just don’t jell so well. Great product, Superb Customer Service!! (Posted on 10/20/14)
More than impressed Review by Mike@550brew
We bought this mill when it first came out. Easy to assemble and get the proper spacing correctly. We have crushed well over 200lbs of grains so far with no issues. Our largest single crush was 50lbs of grains for a single batch and not one problem. (Posted on 10/7/14)
Consistently the Best! Review by HockeyHomeBrewSki
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. (Posted on 6/10/14)
Solid Mill....Great Crush Review by Chris
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.

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!!! (Posted on 4/16/14)
Well built, excellent performer Review by Andrew
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.

Works great, easy setup, very sturdy and cool design Review by Ken K.
Used this mill for the first time today, and it worked great. I want to say something about the base and hopper that people seem to rag on, even though it is acrylic, it is very strong, thick and the base fits perfectly around the bucket. Assembly took all of 2 minutes. The rollers are stainless, which is a big price difference on the monster mill, as well as the hopper for a monster is $45 extra. my efficiency after adjusting the gap 1 step smaller is 87% according to BeerSmith. This is a great mill and I am glad I pulled the trigger on this, even though i didnt get it at 20% off, got the free 50# 2-row deal. Great mill. (Posted on 2/23/14)
Nice adjust mill, clear plastic is a plus, not negative. Review by Drew
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. (Posted on 2/16/14)
