Good day all. I want to brew a larger batch using my limited kettle. Normally I can get about 15 liters into the fermentor but this time I want about 30 liters so that I can keg and bottle the remainder. It seems that the best option is to brew a higher concentration wort and then just dilute before pitching the yeast. It looks like I have two options when it comes to doing this in the Brewer's Friend framework: I can set up a 15 liter batch that will end up with an estimated OG and IBU that is double what I want in the end and then I just dilute. I did this by simply setting up the recipe for 30 liters and then in stead of scaling I just changed the target volume to 15liters. The ingredient amounts stayed the same as for the 30 liter batch but the OG and IBU's obviously increased. The problem with this is Brewer's Friend thinks that I'm making something way out of style and it complains thus. My other option is to set the Target Volume to 30 liters in the fermentor and leave the boil volume about 20 liters. It seems like the OG and FG matches up for the final product, but when I want to brew it it wants me to sparge with almost 20 liters so that I get a pre-boil volume of about 40 liters (which is impossible, my kettle is only 20l in volume). It seems like it's ignoring the 20liter boil volume I set in the recipe. Can I just ignore this mash issue and just mash with whatever's needed to result in 20 liters pre-boil? Will the IBU calculations work out after I top-off with fresh water before pitching yeast? Is it even a sound idea to dilute with 1:1 water? Thanks for any and all help with this!
