    Great buy. Review by Mike
    Does a great job and worth the cost. I can now have fresh milled grain for brew day. This thing chews through the grain and provides an excellent crush. If you have a drill, use it and save your arm! (Posted on 2/13/15)
    Difficult to adjust setting Review by Bill B
    The mill comes with the roll gap setting ready to use out of the box. My brewing buddy and I decided to adjust the gap a little closer to get a finer grind, and found out this was difficult to do. The knurled adjusting knobs don't move in tracks, and they slip when you turn them. We tried using a feeler gauge and adjusting one side at a time, but this didn't work well. The best way to adjust the roll gap is to insert a thin piece of cardboard across the entire gap of the rollers. We used cardboard from the back of a pad of paper. Then use the adjusting knobs to move the roller up to the cardboard so the adjusting roll is even all the way across, and then tighten the set screws. Run some grain through and see if you get the desired level of grind. You probably will need to loosen the rolls and add several sheets of paper (one or two at a time) to the initial piece of cardboard to get to the desired grind level. My advice is don't mess with the setting in the first place.

    Other than this gap adjustment issue, we are very pleased with the mill and end would recommend it. (Posted on 4/9/14)
    Very good a couple of annoyances Review by FNM
    Used this for the first time having wanted to use my grains as fresh as can be and save a few bucks crushing it myself. Very simple (minutes in fact) to assemble though I found a couple of teething problems.

    1. The handle screw had to be ROCK solid and screwed in with all my might for the grains to crush. Until I did this it span around like the rollers were filled with grain and didn't crush at all

    2. I thought for my next brew i'll try with a drill. The handle is extremely hard to get off once unscrewed - not clear to this day if I have to whack it off (it's still on)

    3. I put my crusher over a bucket and find it slips a lot while using the handle. Maybe it's me and lack of technique but it annoyed me enough to motivate trying a drill.

    4. You will need a couple of extra things - some grains to run through before operation to get some potential manufacturing oil off - I used oatmeal as I didn't have 1/2 lb spare. You'll also need a brush to clean the rollers. (Posted on 4/1/14)
    Great product and I would recommend to anyone doing all grain batches! Review by Kale
    The product itself is quality and crushes the grains just right. Much better to keep the grains fresh and crush them at home rather than getting them pre crushed. If I had two more arms I would give this 4 thumbs up. (Posted on 1/31/14)
    as advertised Review by Matthew
    I only have one batch through this mill but it seems to be everything it is supposed to be. I adjusted the rollers and ran though a batch. 7lb hopper held...wait for it 7lbs of grain. Crushed 12lb grain bill in a matter of minutes. Also, increase my efficiency 15 points over LHBS crush. Used with a cordless drill. (Posted on 1/13/14)
    Haven't used yet, but sturdy construction. Review by Brad
    I've got 2 extract kits to brew and then my first all-grain batch. Can't wait until I get to use this. Construction is solid. Assembly of the hopper was easy. This unit comes with a handle or can be used with a drill on a low speed setting. (Posted on 1/3/14)
    Great mill Review by Jesse
    Easy to use and provides a great crush. With the use of a drill its so quick and easy. (Posted on 12/12/13)
    Works as advertized! Review by gregory
    I leave a corded drill attached. Produces a perfect crush right out of the box. Great product. I expect to get many years of service out of this one! (Posted on 12/9/13)
    Great functionality and good price Review by Richard
    I've brewed one batch of all-grain beer so far with this purchase, and found it very easy to set up and use. I did not use the manual hand crank that is included, but instead used my plug-in electric drill. The axle of the mill perfectly fit my standard Kyobi drill. I ground 13 pounds of grain in just about two minutes. I like having my own mill (instead of using a local shop's mill) since I can control the milling width myself and have a consistent crush, so my recipes will turn out more consistently. I've used the factor-set width, and ended up with a 75% mash efficiency, which is very satisfactory for my set-up. (Posted on 12/4/13)
    Very nice. But could use some refining. Review by SunshineLock
    This is a nice crusher. The first time I used this I used my drill. I crushed about 7 lbs of grain very quickly. The one thing that I noticed is that the shaft should be about 1/2 inch longer.

    The next time I used this my drill was on the fritz, so I attached the handle that came with the machine and did this manually. I had 20 lbs of grain to crush. It took a few refills of the hopper, but gave a nice break for my arms. It was a slight work out, but nothing horrible. And again, I noticed the shaft should be 1/2 inch longer. I had this hopper on top of a plastic bucket and the handle kept hitting my bucket with every turn. That extra 1/2 inch would have made a big difference. (Posted on 12/2/13)
    very good piece of equipment Review by Enrique
    Very good, it works grat for small quantities and the malt is freshly mill in your brew day (Posted on 11/26/13)
    Easy to use! Review by Thor
    Easy to use and easy to adjust. This was a great purchase, a must for anyone making the leap to all grain brewing. (Posted on 11/20/13)
    everything it needs to be Review by Philip
    I got better than 80% efficiency from my very first AG mash - and I believe that is partially due to a good, consistent crush. And this was very easy to use. I used the handle at first, which is easy, and then, just for kicks, hooked up my drill to the shaft, which was lightening fast.

    I see no reason to go with a bigger hopper as long as my batches aren't any bigger than the 10-12 gals my system is capable of now. It's just too easy to reload the hopper a few times while you're crushing.

    The whole crush for a five gallon batch takes 5 minutes.

    Tip: get a thickness gauge right away and use it to insure the mill is set properly. Mine was a little cockeyed from shipping but I did the simple adjustment before the first crush. (Posted on 10/29/13)
    Crushed! Review by Friz
    After moving up to all grain brewing I coundnt see not having a grinder.This unit fits the bill and beyond!For the price and quality it cant be beat!Best of all its American made! (Posted on 10/25/13)
    Motorized mill Review by Robert
    This is a great mill. I took a 1/2 HP. The motor is running at 1725 rpm's and put a 1.5 pulley on it. I used 5/8 pillow blocks with a 6 inch pulley on it connected via a 3/8 to 5/8 spider hub coupling. This made it run at 441 rpm's. The mill works great at that speed and does not even start to bog down when pouring the grains in. (Posted on 10/10/13)
    Just right for BIAB Review by Steven
    Used the crusher right out of the box for a Smashing Pumpkin 2gallon BIAB. With the factory setting I got 77% efficiency without even running the grain through twice. Excellent product! (Posted on 10/3/13)
    excellent Review by WILLIAM
    This mill does a great job on grain. I turn it by hand and I can do 10 lbs of grain in 10 minutes. It gives a nice crush without turning the grain into flour. I am very happy with the performance of this item (Posted on 10/2/13)
    Buy a good drill, consider remounting Review by Alex
    My cordless 9V drill was unable to crush the grains. Some people have had success with other wireless 12+ Volts, however, I ended up buying a strong wired 9A power drill. Now I crush grains evenly, at record speeds.

    If you don't physically mount the surface, then invest in some heavy duty clamps. My little clamps were not able to support the weight off the end of a table. (Posted on 10/1/13)
    Buy a good drill, consider remounting Review by Alex
    My original 12V wireless drill was able to turn the rollers but it was unable to actually crush anything (very slow). I had to buy a wired/plugin 9A power drill ($80-$90). Now I'm able to crush grains at record speeds. Some have had success with wireless drills but mine did not work.

    The board it comes on is sturdy. But the weight may be too heavy for certain clamps. If you don't physically mount it to something, then invest it some heavy duty/sturdy clamps. (Posted on 10/1/13)
    well built and easy to use Review by Eric
    I bought this because i got started buying grain in bulk. let me say i LOVE this mill. makes my brew day much more convenient. (Posted on 9/16/13)
    Works great Review by Edward
    This thing is great. I'm still using the handle but really wanna try setting it up with a drill. As other posters have said, that really makes milling a breeze. (Posted on 8/27/13)
    Good mill Review by TN
    Arrived super quick. Easy to set up. And easy to adjust gap. (Posted on 8/27/13)
    Great product for a great price Review by unionrdr
    This crusher is def worth the money for brewers like me that do partial mash. Especially biab partial boils as well. The factory setting of .039" is perfect for an even crush with little flour residue. And the hand crank,properly positioned & tightened,works just fine. My efficiency went up a few points with this one. (Posted on 7/18/13)
    Does a good job - if it stops working replace O ring Review by Shannon
    Does a good enough job. However, if it stops working, check to see if you still have the rubber O ring on the roller. If not, you need to take the rollers apart, buy an O ring, clean and oil the rollers, relace the O ring and it will work like new. (Posted on 7/7/13)
    Great right out of the box. Review by ZBco
    Provides perfect crush with no adjustments. Would suggest using 18v or 24v cordless drill instead of the handle. Makes a much quicker and more uniform crush with a constant speed. The handle is kind of hard to line up with the groove on the spindle and the intermittent speed creates uneven crushing. If I had to do it over I would buy the bigger hopper but one can be built easy enough. Overall a great investment and awesome improvement over my old Corona mill (aka flour mill). (Posted on 4/3/13)
    Great Value Review by thebrewgeek
    I've used this crusher for over a year (about 25 batches) and absolutley love it. I only use it with a powered drill and have never had any problems. I kept the factory settings and my efficiency is a consistant 73% - 76%. The O ring snapped off after about 20 batches but it has no effect on the product. This product rocks and highly recomend purchasing it. (Posted on 2/11/13)
    Very sturdy and fast Review by Thomas
    This mill does a great job crushing my grain. Usually does about 20 lbs of grain in about 2 minutes using my cordless Dewalt...doesn't even put a dent in my battery charge. (Posted on 9/10/12)
    Great mill Review by sol
    I regularly achieve 85% eff batch sparge using the factory set gap. Thats using a 12V drill at max speed. Get a name brand cordless drill Makita, Dewalt, Hitachi, Milwaukee, etc... Cheap brands like Black and Decker dont have the power to get the job done and will leave you hand cranking the rest of your grain.

    Only issue is that the hopper only holds about 8-9 lbs of grain and most of my recipes call for around 10-11. They sell one with a larger hopper, but it really isn't an problem just convenience. (Posted on 7/27/12)
    Definitely use a drill Review by Jason
    I haven't even bothered to attach the handle, knowing beforehand that I was definitely using my drill with this thing. This is my first mill I've ever bought/seen/used/etc., but I've been impressed with it's performance. Only knock (which is more my fault) is that you need to check the mill spacing prior to your first use. Spacing must have been altered during shipping. I assumed that it would be set at what the "default" setting and I ended up crushing my grains too fine (equaling a stuck sparge). However, next batch, I adjusted the spacing appropriately, and we had success! (Posted on 5/23/12)
    Ditch the handle and all is well Review by Mike F.
    I just purchased this from northern brewer and my first thought was this is garbage!!! I was using the handle that came with the mill after five minutes of fighting the thing I gave up and hooked up the Bosch drill and all was awesome! I get the same efficentcy I get from buying milled grain but now can mill what I want when I want without having to drive to pick up grain. definttly recomended! I just brewed a total of three batches without issue using the factory settings. (Posted on 3/25/12)
    O-Rings Review by Beer in Utah?
    Awesome mill! Just FYI if you dont have a heart attack like i did. The BC comes with factory O-rings that are for Q&C testing and such. They will fall off and end up in your grain! I had 1 O-ring the first time i used it and 1 more the 2nd. It does not effect the function of the BC which i found out by searching online brew forms. Only 1 roller turns and the other one is passive with the grain. (Posted on 3/13/12)
    Killer crusher Review by JB
    The first time I used the BC I used the hand crank like a sucker. It took me around 30 min. to crush the grain for a 5 gallon batch. The second time I hooked up my drill and went through 14 lbs. of grain in jus a few minutes. The BC is one of the best home brewery investments I have made. (Posted on 2/26/12)
    POS Review by jason R
    Only for the average homebrewer!! I brew two or three times a month. I used mine for 1 year and the knurls have chipped off or flattened. Now the rollers don't even grab the grain and push it through the rollers. Total crap. I bought this because of the price, but as Dad always said buy the best you can afford and this POS is the perfect example of why his advice is gold. It might be a best seller, but that is because of the price not quality. This is the only product from NB that has disappointed me and I shop here several times a year! (Posted on 1/12/12)
    Use a 5 gallon cooler Review by Daniel
    Love this crusher, my efficiency has jumped from the 50% to +70%. Works real good. When grinding it works great over a 5 gallon round cooler. If your using a drill, usually an 18 volt battery will only make it through about 6 lbs of grain. So have extra batteries or use the handle. I bought this directly from the maker, but the price is the same here. Real happy with northern brewer, so if I had to do it again, I'd buy it from them. (Posted on 11/26/11)
    Much better design than the B3 Grain Gobbler Review by R.Gibson
    I used to have the B3 Grain Gobbler 4" grain mill, and it worked "OK," however, I was never really impressed with the build quality, and in fact had to return the first one they sent me because the bushings were all bored out and sloppy. The second one was only marginally better, but figured it was as good as I could afford, so I kept it. I sold it a few years ago when I got out of brewing for a while.

    Recently I just got back into all-grain brewing, and bought one of the 4" barley Crushers from Northern Brewer. I just received the Barley Crusher, and was immediately impressed with the build quality. Everything is made out of metal, rather than being mostly plastic in construction, the bushings are nice and tight, and the overall build quality is excellent.

    The hopper is also MUCH easier to use. Since it is wider at the top, you can easily pour your grain in from another bucket. With the B3 mill I had to put a large funnel on top of the makeshift LME jar with a hole cut in the bottom that it came with.....

    I think my favorite feature though is the fact that the piece of wood that the mill is mounted to fits perfectly over a plastic bucket, sealing the grain dust in during the milling process. Previously when using the B3 mill, I had to move outside to prevent contaminating everything in the garage with malt flour.

    Also, the bottom of the mill board is fitted with little "feet" that prevent the board from sliding around on the top of the bucket...while still allowing the mill to be quickly and easily removed after milling...whereas the B3 mill is hard-mounted to the bucket, which makes removing the grain from the bucket more of a challenge.

    ...again, excellent attention to detail and build quality. Add to that it's actually less expensive than the competition. This is hands-down the best value in home-brew-sized grain mills! (Posted on 7/18/11)
    Must have Review by Max
    Great price and it works great too. Lifetime warranty sold me 100%. I take my time when the drill is on it cause I'm in no hurry but it will go fast too. I got a $10 used drill and am glad I did because after 13lbs it gets pretty warm!!! You can find it a little cheaper elsewhere but if you buy ANYTHING else with it the $7.99 shipping pays the support Northern Brewer and order some grains at the same time!!! (Posted on 6/10/11)
    Great buy! Review by Joseph
    Well I've had mine for two years now, and after talking with the makers to be sure that there were no issues motorizing it (constant one-sided pressure against a bearing is likely to cause wear, I figured) they told me that there were no issues, and that the bearings were guaranteed as long as I owned it, no questions asked.
    I hooked mine up to a gear motor with chain drive. This thing would pass your mother in law if you so chose (most people don't use gear motors, and have a much faster turn rate -suggested is about 200-300 RPM, but mine is considerably slower. I'm in no hurry. Freshly crushed grain can't be beat. I mounted it and haven't looked back. I've had NO issues of any kind with it. I did try resetting the rollers a little tighter, but some stuck mashes convinced me that the original factory settings were just right. So they are back to original and will stay that way (grin).

    Good once you know what you're doing. Review by AussieBrewerinColorado
    For new buyers, I recommend if you use with a drill, just go full force with your hopper full of grain. I tried to "test it out" with a little grain first and had a horrible experience, thought I got a dud or the rollers were too far apart. But once I just put it all in, all went well. The drill will give a bit of kickback so don't think something is wrong if it gets jerky, just put more speed.
    My only issue is the hand cranks (I got 2, don't know if that is normal), are hard to get on, I don't know if the hole is too small, but even when I screwed it down it slipped. So for me, as long as i'm using the drill it works great. Can't comment on hand crank because it wouldn't work for me. Also, if you use a drill, use a plug-in one! First time I tried a friends mill, battery died halfway, too much hassle. (Posted on 4/10/11)
    great crusher Review by swib
    I had three reasons for buying this mill: 10 gallon all grain batches require a lot of grain, i can be sure my grain is very freshly milled, and in the long run it will save money because unmilled grain is cheaper by the pound. If any of those apply to you, then get this mill, it's rock solid and works great even at the factory preset gap. (Posted on 3/22/11)
    go all grain Review by Waszup
    The crusher fits on top of a 5 gallon pail to catch your grist. The rubber o-ring was spun off during its first use but the crusher still functioned. I won't replace it, the crusher doesn't seem to need it. If you're hand cranking it will become tiring. Combined with yeast washing and using grain I expect this to pay for itself in 7 uses plus better tasting beer. cheers. (Posted on 3/9/11)
    Great Crusher Review by Lui in Idaho
    I purchased this item this spring when I moved to all grain brewing. I chose this particular brand and model because of the features it offered -- dual rollers and full adjustability. (To be honest, I have yet to adjust the setting.) I thought that the price was much less than the Schmidling Mill or the Monster Mill, and it wasn't that much more than a Corona Mill.

    I do not use a cordless drill, but I do use a corded drill with a keyless chuck. This thing will run through 10 pounds of grain in no time. This is one great grain mill. Love it! (Posted on 1/22/11)
    Warranty is worthless Review by Mike
    My barley crusher came with a bent roller. I contacted BC products to either return the crusher or to get a new roller so that I could fix it. They offered to sell me a replacement roller for $50 - for my crusher that came defective.

    Repeated calls and emails have been ignored. (Posted on 1/14/11)
