When you run BIAB as a full volume, no sparge process, it does tend to be lower mash/lauter efficiency than an inherently sparged system. Woah, we actually hit on an actual piece of controversy. My BIAB wort going into the fermenter is as clear as any 3 vessel system beers I've ever made.Ĥ. How would you account for the hundreds of people who have owned 3 vessel systems and switched to BIAB?ģ. You probably mean that you have been drooling over pictures of shiny brewing systems that feature multiple tanks and pumps and you have it in your head that a system like that is the end game for 'reasons'. I'll just BIAB until I can afford to upgrade to an all grain system (or some other disconnection of terms due to ignorance). If anything, BIAB should be a sub forum to All Grain Brewing.Ģ.

Even HBT has BIAB as a separate forum from All Grain Brewing. BIAB relies on the same mashing and ends up with the same wort. You derive most, if not all, of your wort's sugars from cereal grains through the mashing process. All grain brewing is very simple to understand. BIAB is not real all grain brewing (as an outright proposition). Here are some random things you'll find.ġ. It's painfully obvious that so many people, even long time regulars here at HBT do not get it based on the comments they make in various threads. Some people will read that and think, 'yeah, I get it, what's the point?'. The premise however is that the defining characteristic of BIAB is that the grain is contained in a mesh 'vessel' within the boil kettle and the grain is remove from the wort (not vice versa like in a typical mash tun). The reasons and/or mechanics of sparging are not really the point of this post so I'll skip it. In some cases, the mash is performed thicker and a sparging step is added after pulling the bag or basket. The preboil volume of wort is usually achieved by using enough initial water to yield the desired volume. Post mash, the spent grain is removed from the boil kettle, leaving only wort behind. This is probably going to be pretty disjointed, fair warning.īIAB is an all grain brewing method where the mash is held in a porous bag or basket within boil kettle.

The readers I'm mostly addressing are those who think Brew in a Bag as a process is inferior, makes subpar beer, or is 'okay, but really just a stepping stone to REAL brewing'. I wanted to address a few things that have been touched on in plenty of threads in the past.
