Yes easily...boil 3 1/2 gallons high gravity in the 4 gallon pot and you have 5 gallons...of course not the easiest approach, but it can be done!!!

Most definitely!!!

I usually mash with about 3.5 gallons, maybe slightly more. Start with just over 3 gallons in the kettle, heat up to about 150, add the grains, then top up to the kettle's limit and add a little more heat to get to mash temp. Do a couple of squeezes/dunk sparges and then a final squeeze to get as much liquid out of the grain as possible.

Ended up adding about 1 litre to the boil near the end last Friday, because had done a particularly strong rolling boil and it looked like the level was a little low in the kettle. Managed to get a bit over 2.5 G into the Mr. Beer LBK whilst comfortably leaving a bit of kettle trub, mostly hop sediment, behind.

I did a 2 Gallon, full volume - no sparge, AG Oatmeal Stout this weekend with 4.375lb of grain, and 3.5 gallons strike water.

My 4 gallon pot was full to be sure, but it held.

Wrapped it in a towel, a sweater, and my winter jacket and only lost 2-3 degrees over 60 minutes.

Not too Shabby.

I do 4G BIAB batches using a 3.5g pot for mashing and my 5g brew pot for dunk sparging. I use beersmith to make my recipes and the volume and temp calculations work out perfectly every time. I get about 70percent efficiency so I can't do big beers but it's perfect for average gravity beers.

I wrap my mash kettle in a towel and sit it on the the radiator and never lose a single degree. It's ghetto but it works!
