Hello All, Normally I brew small 4gal batches (BIAB) in my 8gal kettle - because of the smaller batch size, I can comfortably fill enough water in my kettle + grain bill without it all overflowing for the mash. Tomorrow, I want to aim for my first 5gal batch and after running the calculations, I'm going to need 7.63gal mash water, but the total mash volume will be 8.66gal! Not enough space. So how do you experts do it? Is this as simple as mashing with less water in the kettle at the beginning (if so, how much?)...raise the bag with grain....then add more water? Do I just need to heat up the additional water to the mash temperature, before adding to the kettle? Thanks - I just need a little reassurance and wisdom.
