+1 - Just got my 2.5 gallon all grain setup and I'm trying to dial it in. Id much rather be able to repeat and spend another $2 or so on grain.

Additionally, a large beer in that gravity range (1.100) is going to have a lot lower efficiency than usual for most homebrewing setups. Mainly cause you aren't using as much water per pound of grain when sparging. So 71% for a BIAB at that gravity sounds pretty solid to me!

+1 to all who stated that consistency is more important than efficiency. I've been an avid BIABer for the last 5 months.... having close to 12 beers with this method under my belt. No sparge used on this end, and consistently hit between 74-75% efficiency. Fine crush, stirring about every 10 minutes, and draining/spinning/squeezing the bag after. Works every time. Sparging is not necessary at all!

I found that crush was the deciding factor in getting better efficiency in BIAB. Once I got my own mill, and started trying different crushes, I started improving efficiency into the high 70s. I'm hitting 76-78% consistently now, not sparging, and not squeezing my bag. However, after draining my bag above the kettle for a couple minutes, I then suspend it above a small pot to catch any additional runoff. I usually end up with another quart or so...

If you start squeezing the bag you'll find that you can extract another quart or more of really sticky, high sugar wort and that will increase your efficiency. I think you are leaving a lot of sugars by not squeezing.

I used to squeeze, and I used to sparge the bag, and results were inconsistent. Remove them from the process and you gain consistency.
