Hi All,.
I am currently saving for a mash tun esky conversion kit from Beerbelly, but I just happened to come across a near new 30L urn at the local trash and treasure last Sunday for the princely sum of $20 and thought it may be a good chance to try AG sooner than planned. I planned to bring the water up to strike temperature in the urn, then transfer the water into an esky lined with swiss voille for 90 minutes and then transfer the liquid back to the urn for boiling and hop addition.
The more I read, the more I am confused about the water volume required for a BIAB AG.
I'm hoping to produce enough wort for a 20-23L batch. To prevent boil overs (if its anything like using DME) I imagine I can only get away with a starting boil volume of around 25L.
From what I can gather, the water required is determined by the water lost from boiling (around 5L per hour), the grain to water ratio and the water retained by the grain bill?
Most 20-23L AG batches call for around 5kg of grain. Would it be possible to use this amount of grain in a smaller water volume (say 25L) and then bring the final volume up to 20-23L by adding water to the fermenter?
Apologies if I have confused terminology etc, I'm still a newb!
Cheers
