If you're gaining efficiency with a mash out, it means you didn't have full conversion in the first place.

You could either mash longer (if needed), or just skip the mashout (since you're heating the wort right away, which is in effect a "mash out" since it denatures the enzymes) if your efficiency isn't too low.

You can gain a little efficiency by pouring water into the bag of grain and squeezing it out again. No matter how hard you squeezed it the first time, you left a bit of sugars in there.

Putting the bag of grains back into the wort that is already saturated with sugars won't get much more sugars out of the grains.

Ok, so next brew I won't put quite full volume in for my BIAB. I'll keep a gallon or two out and use for a sparge on the grains in the bag to get boil volume?

That seems like a good plan. I usually only use half that much for a sparge and still get the extra efficiency.

Haha.

On a side note. I just transferred this batch into secondary for dry hopping and I tasted the hydrometer sample. It's a Black IPA:

12 lbs. American 2-row
1 lbs. Crystal 20L
1 lbs. Midnight Wheat
.5 lbs. Belgian Debittered Black
.5 lbs. Special Roast

1oz. Amarillo @60min
1oz. Cascade @30min
1oz. Cascade @15min
1oz. Cascade @5min
1oz. Amarillo @Flameout

Currently sitting on 2oz. of Citra leaf hops.

I'm new to all grain so I don't know what kind of indication the taste of the hydrometer is on the finished product.... but it was delicious. My only There was a very slight roastyness quality with mild residual sweetness. My OG was 1.070 and the SG for transfer to secondary was 1.022 (a little higher than my estimated final gravity but still puts it currently at 6.17% abv).

My questions - can i expect to lose a few more points of gravity while it's in the secondary for 10 days or is 1.022 pretty much it?
Secondly - I didn't get much hop notes, will the bottle conditioning bring that out more? I was really hoping on more hop character but my sample from the hydrometer was more malty.
