Hi all. I am fairly new to home brew so please excuse any stupid newbie questions! I'm looking into doing BIAB using a mini setup and want to do 5gal batches on my kitchen stove. I'm interested in mashing thick and using a smaller boil volume before liquoring back to hit my target OG. I'm looking at buying a 32L kettle and am trying to figure out: Best mash thickness. From what I've seen about 2.5L of strike water per kg of grain would be ok, so for an average recipe around 13 - 14L of strike water? Whether to sparge and if so how much? Clearly I could just boil the wort left after mashing but would be concerned I'd lose a lot with only 13L on a rolling boil for an hour. How much to top off at the end to hit my batch size of 20L. I know I can use a calculator to do this but would be good to know if there is a rough rule of thumb. Thanks in advance for any advice you can provide!
