My modified BIAB process is basically using a nylon bag inside a 10 gallon gott cooler. I used no sparge, and I got all my boil volume from the mash itself.

So, anyway, I heated up about 8 gallons of water to around 161F. Then, I drained the pot of water into my gott cooler which had a nylon bag full of grains inside it. I had about 12.75lbs of grain and 32 quarts of water. The grist to water ratio was right around 2.5 quarts per pound, which is by far the thinnest mash I've ever done. This is certainly in the spirit of a BIAB.
A few minutes later, when I checked the temperature, it was at about 158, though. It actually took me awhile to stabilize the system at 154. I am not sure I got the right temperature soon enough, so I might bet a more full-bodied beer than I had intended. But, that is ok.

|This much wet grain is actually pretty heavy.|
|Had some Gringo Cerveza while brewing|
|Used ice to cool down even more.|
At the end, I had just about 6 gallons of wort at about 1.060 OG. Keep an eye on the comments on Phat and Tyred on the SheppyBrew website for an update on how it is going. I think it will turn out well.
