sure the bag is simply a lautering device. but mash thickness does affect extraction ... the thinner the mash (to an extent probably), the higher extract:

re: batch sparge extraction, i was referencing this equipment profiler (really helpful btw) http://sigginet.info/brewing/tools/e...rofile-helper/

sure, the efficiencies into kettle for each method (fly sparge / biab / batch sparge) are simply estimates. though, i typically get 80% into kettle using full volume BIAB, no separate sparging. it averages a batch sparge at 75%

That's what I've been saying, just in more delicate and moderate terms....

I can see how others might see this method as an alternative "sparging" (as many apparently do, so I was speaking to them), but this is technically not the case (technically meaning we're taking this usage of sparging in a strictly defined and literal sense). I wholly agree that if you aren't actively rinsing the grains, there is no sparge occurring.

If you're actually interested in BIAB, then you need to head over to biabrewer.info – you will find the truth on that forum.

BIAB is No Sparge...... this is because there is no need for it. by doing a full volume BIAB the grains are rinsed when you lift the bag out, you could also dunk the bag a couple times to rinse the grains a little more. My last BIAB I was able to get 83% efficiency.... just as good as with all the fancy mash tuns and sparge set-ups.... The result of sparging is attained by performing a full volume BIAB.

Like it has been mentioned before, GO TO biabrewer.info to learn more about the process, I don`t see why people keep arguing semantics.
