For a boil you prob do not want start with more than 70% of the boiler volume, and even thene you need to be vigilant. So thats 17.5l , you will lose (should lose) say 10% from evaporation so thats 16 ish, the then is trub etc etc loss so say 14 litres max.Hi
What size batch can I brew in my 25 litre birko?
I have searched a much so can and can't find an answer. Any ideas on how I calculate this.
Measure the SG at the beginning of the boil and the volume.how are you meant to work out your IBU nick?? unless once diluted you draw 6lts off and boil again for another hour?. Your better off knowing what your brewing not just brewing something and hope that the SG and IBU are going to work out.
Totally. If this is a first AG situation, then I'd suggest not going high-gravity and just brewing to the equipment's capacity.yeah I used to do it but couldnt remember how. Just thought since it may be his first time on AG or high gravity boil then it might make it easier if he understood the concept of adding the additions to a heavy wort and diluting it later
i always start the boil with 92 litres in a 98 litre kettle and am yet to have a boilover, so the 70% can certainly be increased as long as you are prepared to stir a little and have good control over your heat sourceFor a boil you prob do not want start with more than 70% of the boiler volume, and even thene you need to be vigilant.

If you BIAB the figure (I guess) is roughly the same.
Or add a bucket in bucket lauter and knock out 25L.I agree, do standard BIAB, then when you're comfortable with that you can knock out 25-30L batches with Maxi-BIAB
