So I have a new hydro and I’ve tested it’s calibrated properly. Also got my last grain crushed by Brewman (with a finer crush). Used Brewbuilder, it did help me especially dialing a more accurate OG of each grain. As brewbuilder anticipated, I hit my numbers of brew house efficiency of 65% and...

Thanks LC for the technical answers. Love learning about the technical aspects of brewing! Yes Mardoo, also keen to support Australian companies. MJ - I wish I could have gotten on board with the BB! Was my wives 40th and a few celebrations either side of it, and her party that we organised so...

Thanks everyone. What is the connection between crush and lauter efficiency / reactions in the boil / wort clarity? Re the angle of the rollers why is that important? I've saved the link to your post re your mill. Looks brilliant. But sounds like a better idea, if getting this one to get it...

Hey, I'd like to buy a mill for either my birthday in a month or Christmas. I don't particular understand a lot of the factors at play. I know I just missed the Mash Master Mill Master mini, but the timing wasn't right for me, with other priorities. I have read some articles/posts here such as...

thanks Dean. I'm of the opinion too in this situation, if you saw the pic, that the grains were way too course and should have had better efficiency. Going to try one of the site sponsors, who has the size of crush desired as part of his ordering system, on his site. That way I'll feel clear on...

Yep, some great insights from those who replied. I agree, I'll just pass on the information, without being an ass about it. Then I'll just ask for a finer crush. Yes, testing my hydro, that's part of the issue (and my issue). Yes, I'll look to mix my grains better when starting the mash! Yep...

I'm not sure, I took a cup of the wort out of the kettle. Cooled it down in the fridge. So I can't be sure what temp the wort was. So going forward, I'll test the temp of my wort etc before I take readings etc. I'll order a new hydro, test it with water at 15-20 c. Then make sure that the wort...

Thanks Bribie. Success again hitting your numbers!

I’ve just tested the water temp now, and it was 20.5. At that temp I just now got a reading of 1.008. So give that the temp for taking a reading is ok, my hydro is reading 8 points higher than it should. Am I reading that then the right way? So I’ll buy a new hydro soon!

Testing my hydro. It's out of calibration, that's part of the problem! I know it may be a bit hard to read, but I think it's reading 1.006. So that means I'm getting readings that are giving me a lower or higher gravity? A bit foggy today, fighting off a virus. So my pre-boil read 1.030. My SG...

Cool. Good to see someone else's cracked grains. Really does look more broken down than mine! I'll be interested to see what they look like after your mash. Thanks

Ok, cool. Didn't realise about that categorising of things. I'll try and pay more attention to the colour of my grain and doing my mash. Thinking I might to make sure I stir and mix the grains more throughly at the start of the mash next time.

I'll look into Brewman's order tool. Sounds a good idea. Yes, I'll try getting my next grain bill from someone else. I'll taste test my grain when I've completed my next mash. I didn't know they were classified like that. So it's clear the crush is a factor....think my hydro is a factor too...

Thanks for all those points Mark! I didn't know that about what spent malt shoukd taste like. So what should it taste like? I will look into checking the calibration of my equipment as you guys have suggested.

Bribie, look forward to seeing what your grains look like. I'm beginning to think it is multifaceted like Mark has been saying, including some of either my processes or equipment calibration. Bribie, I always read Mark's post with keen interest. Not sure if you sensed any ill in what I said...

Lyrebird by whole corn I assume your referring to the barley? So, therefore the barley could have been crushed finer? What does unmodified starch look like? And if there's unmodified starch then the conversion was incomplete? Have I got that right? Or is that caused by something else?

Understand what your saying Mark. I do have lots to practically learn. But I have been doing Biab over a bit over a year. Back on point, my last brew on this equipment had a mash eff of 65% with no sparge. But I'm always learning from here and The Brewing Network especially. I will do the...

These are my grains, I could get them out as ive just started composting again.

Thanks Jack. So, first I'll check the thermometer first in ice then boiling water. Re my hydro calibration. Are you saying it won't read 1.000 until I find its calibration temp of 20 or whatever it is. Yes, I'll talk to Andrew at The Brew Shop, about what has happened. My last crush, and...

I'll test my thermometer Jack / manticle. Good idea on how to go about that. I'll do that next time I have time. I'll request a finer crush next time. How much finer do you think it might need to be? Or is that completely different for each mill? To test my hydro is calibrated, can I use my...
