So I have been building myself a "brau-clone": a recirculating singel vessel system. It is now at the point in the build where I can start knocking out BIABs whilst I finish off the malt pipe.
Quite a while ago I bought some pre-milled grain packs from the Lord Raja Goomba last November. I was very close to the values in Raja's Brewmate brewsheet except for the pre-boil SG. He had it at 1045 and mine came out at 1032 so I was a bit worried about the efficiency of extraction until I remembered I needed to correct it for temperature. I measured after mash-out so it was about 75 degrees, which puts my corrected SG at around 1050
So my notes during the mash
So on with the photos
My brew station. The laptop receives temp data from the main vessel and fires the element using a PID library
Inside shot of the main vessel. Nothing really that special going on here.
Grain pack: (3.8kg pale ale malt; 500g heritage crystal; 200g cararoma; 40g pale chocolate)
Lord Raja's brewsheet he gave me for the grain pack
Woot!! First AG mash-in
By god, it looks like wort!!!!!!
And I'm spent. This will find a home with a neighbour who owns some chickens....
And the 60 minute boil is on. Nice and simple. 60 minute addition of 15g of pacific gem leaf.
Cleaning and sterilising cube. You can see my ferment fridge (with Coopers IPA 3/4 done) and keg fridge to the right.
If you are wondering why my ferment fridge is open, I plugged it straight into the wall as I was using the laptop to control the mash and it got down to 15 degrees. So just warming it back up to 18 degrees again.
I will be re-doing my electronics control box to allow me to run the fridge and beer system at the same time.
If you wanted to have a look at the fulll build, there is a link in my signature to my "Brewton" thread
By jove, 20L of wort packed in the cube waiting for the fermentation fridge!!!!
So all in all, I think I am pleased with my first AG brew day. Was fairly easy (I need to work on bag hoisting and draining) and my software worked well, main vessel worked well. Just hope the beer tastes good!
My one worry is that the temp probe is at the base of the pot and was measuring 75 during the mash out. I grabbed my digital thermometer and stuck it in the top of the bag and it was measuring 80 degrees. What would be the implications mashing too high?
I also forgot to take a final reading on the gravity. I did take a reading on the trub and crap left in the pot which came out at 1060 or so. I figure this is incorrect. I'll take a proper reading when I drop it into the fermentor sometime next week.

So my notes during the mash
- 7:30: 29.1L pre mash
- 8:30:water temp at 68
mash in and temp drop of 1.8 degrees
mash at 66 for 60 minutes - 9:30: raise temp to 75 for 10 minute mash-out
- 9:45: 25.1L pre boil
SG: 1032 temp corrected to 1051
