I believe BIAB would be considered no sparge, would it not?
Yes, BIAB is traditionally a no sparge one pot brew. Lately, people have adapted the technique to enable the use of a smaller brewpot by the use of either a "dunk sparge" in another vessel (pot / bucket), or a "sprinkle sparge" of pouring sparge water through the grain bag while it is suspended above the pot.
Some even brew a concentrated boil BIAB style and top up like you would an extract batch.
The Biabbrewer.com website has a bunch of terms defining the different methods of BIAB...something like Maxi, Mini, and Midi, ah maybe that's skirts....cheers.
