PM vs AG

[OlRed]

I have been studying up on DeathBrewer's partial mash techniques and I began to wonder what separates this type of brewing from all grain? It seems like you could just substitute more grains for the extract that is used at the end of a partial mash recipe and (viola) you have an all grain recipe. Eventually I would like to do all grain recipes but do not want to go the mash tune cooler route. Could someone help clear up the confusion? Thanks.

I do three-gallon, all-grain batches on my stove with the brew-in-a-bag method, so it is essentially the same method without adding any extract. I do the mash on the stove.

I'm limited by my kettle size, and could do five-gallon batches by adding the necessary extract to the boil and then topping up with water later, but am happy with three gallons at a time.

If you substituted out the extract for grains (and added more water accordingly) then you are doing BIAB all-grain brewing.

Sometimes, folks dont have the pot volume or ability to heat 6.5 gallons of water at once so they PM instead of a full AG.

Nothing different at that point.
