Heated 18l of mash water to a temperature of 72. Threw in my almost 5kg of malts and it sank to 68 degrees. Perfect!

During mash it went up to 69 at times but with a blanket around it it kept the temperature quite nicely. Added 11 litres of water through the grist after mashing. Kettle pretty full, guess 24-25l.

Pre-boil the whole thing was way darker than what I had expected. Also the post-boil OG (adjusted from 51C) was 1.049 which was way off the expected post-boil OG, this perhaps because of too little boil-off during the boil. Later when the wort temperature had cooled down the og was showing around 1.052, pre-boil this number had been spot on but now it was off. It seems that my boil-off rate of 4 litres still was okay because I left around 1litre of trub and threw 19litres in the fermenter.


FG Ended up at 1.006 which should give an ABV of 5.64.

I put co2 2.5 instead of planned 2.2 because of a miscalculation, so the end result will be a dark beer that's more carbonated than what it was supposed to be.


Mashing might have been with too low temperature, the ending beer was very low-bodied. Aroma was okay but there was pretty much no flavour at all, a bit sweet, more flavouring hops needed.



Could be used for several mid-range AA. Considering doing it with Marynka Polish hop.
