Is there a target efficiency that I should be trying to achieve? I generally get around 73%. Should I be trying to improve that?

Not in my opinion, that's pretty good for BIAB. Your efficiency only affects how much grain you need to achieve your target OG, not how good the beer tastes.

If I'm doing a "regular" beer I tend to get 72-75%. Higher gravity gives me lower efficiency, and session beers usually give me 83-85%. Figure out efficiency at various levels and strive to keep it consistent.

Thanks guys for all the help. The long story is that I am using a 44qt Bayou fryer bucket and I have a 14 1/2 lb grain bill and rackers says that it will take up 5 gallons of space, so I will be using your info to do my first biab

While the bag is dripping after Mash Out, can I be heating the wort up to boil temp? Or do I need to wait for the bag to finish dripping?

Heat away, no need to wait until it finishes dripping.

No need to wait. Bring the heat!

I attempted BIAB for the first time today, going from extract brewing. It did NOT go well. I was trying to make this: http://www.homebrewtalk.com/f78/holl...as-ale-145580/

My pre-boil efficiency came out to be around 57%, unfortunately. I have two theories based on what I observed today.

1. Bag Size: I used a 5 gallon paint strainer from Lowe's, which seems to be the norm around here. I think this brew was a little too big for this bag. First of all, I discovered that bag's mouth does not cover the opening of the kettle. In fact, I could only stretch it across about half way. So because of this, I added the grain to the bad OUTSIDE of the kettle. In hindsight, this prevented me from adding a little bit slowly and stirring as I pour in the grain. Also, because the bag was so full I think it was packed a little too tightly. This prevented the water from really getting in there.

2. Mash Temp: Because I added all the grain at once, the water didn't slowly get to the right temp. I got the strike temp to about 160 and tried to stir as best I could. But 30 minutes into the mash, I checked and the temp was around 142. I immediately heated back up and I added some time to the mash. I did wrap the kettle in blankets. I don't think I necessarily LOST that much heat, but my strike temp wasn't initially high enough and after I added the grain it was packed so tightly that it didn't immediately drop the temp down a lot, but as water got into the grain it brought it down more than expected.

I think overall 1 was more of an issue than 2, but both definitely played a part.

I added some DME and my actual OG wasn't too terribly off the target for this beer. 1.066, which is what some people in the thread for that recipe have reported when doing BIAB.

I am disappointed but I think I learned a lot. Do my guesses as to what went wrong seem possible? My biggest takeaway is that I need a larger bag (hello, http://biabbags.webs.com/). I really should have done a smaller beer for my first...

Did you have clumps because of issue number 1? I can definitely see that affecting efficiency.

I can highly recommend the bags from Wilserbrewer. The site is http://biabbags.webs.com/ (not sure if that's what you meant with the link).
