Not that hard...Add enough water and grain to get yourself an OG over 1.060 using what I can only assume is a brew bag or brew basket. Right @Steve G. ?
That is how I do it. I have a bag for my 25 g kettle and do BIAB in the one vessel. Getss close to the top with some mashes.
I am a first time poster here, but have been lurking for years. I am a 3v brewer, but also do BIAB. The downside I saw to BIAB or all-in-one units is high gravity. For Christmas, I got a 25 gallon boil kettle so I can do high gravity all in one and still fill two 5 gallon cornys. I cannot relate...
