It eliminates the mash and sparge vessel, thus saving the brewer money. All this to say, if you want more precision, you need to measure what your actual system is doing and make adjustments accordingly rather than relying on a suggested constant and playing with water volumes. Efficiency: BIAB turns out to be more efficient than batch sparging because the sparge water is actually in contact with the grain for the entire mash time.As BIAB has been adopted by the larger homebrewing community, many of the concerns surrounding it as a brewing method have proven unwarranted. Wort Quality: BIAB wort is usually cloudier than fly sparging wort because there is no recirculation step.īIAB brewers report efficiencies between 70% and 80%. Mash Temperature Drop: BIAB has a larger thermal mass than other sparging systems because all of the water and grain is in one vessel.This can result in larger amounts of trub going into the fermenter, but tasting trials have shown no differences in finished beers in triangle taste tests.
This helps prevent temperature loss and can be augmented by surrounding the kettle with insulation of some sort. Patrick is an active member of the BIAB online community.

This community provides a lot of free information on BIAB and works to promote this simple, yet efficient method of all-grain brewing. If you have ever thought of giving BIAB a try, be sure to listen to the BeerSmith interview and take a look at BIABrewer.
