It Mills nicely and it's easy to change the size of the crush. It's also fairly quick. The only issue I have is the ridiculously small hopper. But I just keep scooping grain in and it works ok that way. 1 Link to comment Share on other sites More sharing options...

I think it was the guru @Shamus O'Sean had made one for his mill. He might be able to guide you on how to do it. 1 Link to comment Share on other sites More sharing options...

So it will probably not help @Aussiekraut. The GrainFather one is circular, like an upturned half a 2 litre PET soft drink bottle. It is probably harder to fashion something for that shape. My cardboard grain mill hopper extender. Made from half a kegerator box. I was surprised how much cardboard "real estate" was needed for the whole contraption. However, it will hold 8kg of grain. 6 1 Link to comment Share on other sites More sharing options...

The problem with the GF mill is that it is a round hopper, which makes it hard to extend. It is possible but I don't know how sable it would be. 2 Link to comment Share on other sites More sharing options...

For those who don't know, Clausthaler is a pioneer in alcohol-free beers in Germany. It never had a great reputation, mainly because it had no alcohol and in the 80s, this type of beer was the butt of many jokes. Their slogan used to be "Immer? Nicht immer, aber immer öfter", meaning "Always? Not always but more and more often". They used to have this cool ad though. A guy stands at the bar and an interviewer asks him about alcohol-free beer and the fella says yep, I like it but only Clausthaler. When asked why, he says well, it works. The dog listens better than before. He tells the dog to sit and it doesn't, so the interviewer says "Always?" and the guy replies "Not always" and when the dog sits down, "but more and more often". i have heaps of german glasses and La tappe from holland as the Missus is Dutch and do trips there to see her daughter's love europe Austria would be my favourite place 2 Link to comment Share on other sites More sharing options...
therealthing691 Posted January 6 Author Share Posted January 6 Well tightened the gap to 1.3 see how I go next weekend bb pilsner 5kg and bb wheat 1.5 1 Link to comment Share on other sites More sharing options...
therealthing691 Posted January 10 Author Share Posted January 10 Well seems better will see . I timed the process 2.45 for 6.5kgs and the hopper holds around 3.5kg .Will brew on the week end and find out 1 Link to comment Share on other sites More sharing options...
therealthing691 Posted January 13 Author Share Posted January 13 (edited) 69% BHE which is not bad what are others getting that mill there own grain. I had the but recirculation in mashing ever in this brew . Might try .5mm tighter or just leave as 69% is fine by me cheers enjoy the weekend Edited January 13 by therealthing691 typo grammar Link to comment Share on other sites More sharing options...

Previous brew day was for a 44 L COPA and I got mash E = 85.0 % and BHE = 81.3 %. I use a three roller Kegland mill that is set halfway between the 0.063 ad 0.032 marks on this pic. Note red mark was put there for reference and was its factory setting not what I actually use. Edited January 13 by iBooz2 1 Link to comment Share on other sites More sharing options...

I mill at 0.045 inches. This works for regular grain and wheat, which is slightly smaller. The G30 system includes sparging, which helps with efficiency. You need to be careful with the potential of your grain. It can over-inflate your BHE. The default for Coopers Pale Malt in Brewfather is 1.035. However, I think it is much better. Probably 1.038. If you leave it at 1.035, it can make your actual BHE seem much better. 2 Link to comment Share on other sites More sharing options...

If you leave it at 1.035, it can make your actual BHE seem much better. I mill my wheat first then tip it on top of the rest of the grain bill then mill the lot again. Effectively mills the wheat twice. Re the potential of the CPPM. Yes, I pointed this out to the forum back in winter - spring 2022 . When I went on the Coopers Spec sheet for this malt it said 80 - 83 % which to my mind equates to a potential of 1.037 - 1.038 but when I used 1.037 I was always off with my points both pre-boil and post-boil so my ABV was out even though volumes all good. I use 1.036 for my CPPM, CPAM and also for MO in Brewfather and my points as near as Damnit every time. The high mash efficiencies for my Aussie lagers are probably because Brewfather does not handle the addition of sugars late in the boil properly IMO. I have also found another Brewfather bug which I will bring to your attention in another post. I don't add sugars to my ale recipes so I will go back through those to see if I can see a pattern and get my averages over several ale batches. 1 Link to comment Share on other sites More sharing options...

iBooz2 Posted January 14 Share Posted January 14 1 hour ago, kmar92 said: What sugars are you adding late in the boil? In my Brewfather recipes it may have 300 - 500 g of cane sugar or dextrose to be added at 10 mins. For a typical Aussie Lager Beer. It calculates all the gravities and ABV correctly, but I think it's a bit off with calculating the mash E. Thinks my mashing is way more efficient than it really is on those batches. 1 1 Link to comment Share on other sites More sharing options...

I haven't looked into it closely, but BF should be calculating mash efficiency using the pre-boil figures and if it is it will not affect your mash efficiency adding sugars to the boil. 1 Link to comment Share on other sites More sharing options...
kmar92 Posted January 14 Share Posted January 14 @iBooz2 quote from Brewfather: Quote Mash Efficiency: The efficiency of your mash procedure, up to pre-boil, including sparging. Important factor in calculating your Pre-Boil Gravity. 1 1 Link to comment Share on other sites More sharing options...
therealthing691 Posted January 26 Author Share Posted January 26 My efficiency is calculated off brewers friend recipe builder.. Don't know if that makes any difference. I am doing a brew now set at 1.2mm on mill master and all looks good getting great recirculation better in I ever have . Will post the numbers tomorrow .70 or 80bhe is not much more or less grain on a 26L batch so all good .. Will be interesting to see ..As I have only just started milling my own I want to find a sweet spot on the mill cheers 2 Link to comment Share on other sites More sharing options...

BTW, how are you measuring the gap in your Millmaster? With mine, being a 3-roller job, you just about have to pull it all apart to get a set of feeler gauges into and between the crushing rollers just to take the measurement. FYI - last brew day I did was a USPA for 44 L and achieved a BHE = 81.2 % and ME = 85.0 % 1 Link to comment Share on other sites More sharing options...

Still got good recirculation and Sprage and that was with 5kg pale 1kg wheat and 1.5 rolled oats. Got just over 70%bhe ... Might try it just a little tighter but all good . I don't care about a few hundred grams of grain more or less . I am looking for easy flow as all my brews have wheat and most oats as well ... Used about 170grams of rice hulls as well 2 Link to comment Share on other sites More sharing options...
