Is Palmer's "No Sparge Method" an early version of BIAB?

[msa8967]

Buddy of mine sent me this article from 2002 in BYO written by John Palmer about breing beer w/o sparging. He mentions the key is to use 20% more grain than standard and that this will help prevent problems with pH and tannin extraction.

I would like to know how his method described 12 years ago might differ the BIAB that we use now. When I use BIAB I am not adding in 20% more grain than my standard recipe. I am curious to leanr the origins of BIAB as a no sparge method of brewing.

For starters he doesn't use a bag, he uses a cooler with a false bottom. BIAC vs BIAB

The bag is the false bottom and lets you utilize a finer crush that would cause a stuck sprage with a traditional metal false bottom.
