The maximum grain bill to have got into my mash tun previously was 91kg. This was achieved by some Crazy American Brewer back on 28th May 2007. The resultant beer was called Colonial Anniversary(5.6%) due to it being said brewers wedding anniversary, if I remember correctly. He was, in my brewery, 8 time zones away from his wife - that's dedication for you. It was also nearly exactly 12 months since this gentleman stumbled on our humble hostelry. A double anniversary.
Today I got 102.5Kg1 in my mash tun, I don't think I could go much more without the sparge arm fouling on the mash. This should result in a beer that is over 6% ABV. The 3kg of hops might just be right, I reckon.
I think, at some time in the past, I promised to post my water analysis figures. I've just found them:
Appearance: Clear colourless liquid(!) free from suspended and sedimented solids.
PH Value 5.22
Calcium as Ca 1.6ppm
Magnesium as Mg 2.4ppm
Carbonate as CO3 2.4ppm
Sulphate as SO4 1.02ppm
Chlorine as Cl 5.4ppm
Nitrate as NO3 2.5ppm
Alkilinity as CaCO3 4ppm
Total Hardness 14ppm
1The recipe calls for 245lbs 7oz of grain. I'm actually quite close. Oh, and thanks Roger for helping our again. I seem to remember it was an Oregon inspired beer that we needed you help with last time.
