BIAB efficiency

(1/5) > >>

jklinck:
I'm curious what type of efficiency people are getting with BIAB? I'm especially curious about anyone that is measuring mash pH.

weithman5:
i don't boil in a bag but i mash in a bag, not quite the same thing.  however i run around 70 percent. i do check my ph with strips on occasion but i really don't make any adjustments.

erockrph:
I do my mash in a cooler instead of my kettle, but it's essentially BIAB since I do full-volume/no sparge. Plus, I squeeze my bag. I just mash in the cooler to help hold temp during the mash.

I hit 80-81% brewhouse efficiency with a fine crush. If my grains aren't crushed as fine as I'd like (I don't have a mill yet), then my BE is in the 72-74% range.

I don't have a pH meter yet, but I use Brunwater and shoot for 5.3 for most beers. So far, so good.

beersk:
I've only done 2 batches, but I got around 80% efficiency.  I mill pretty fine, gap is set at .030" on my barley crusher. As Jake Keeler says, I goose it to keep the mash temp in line.  I mash in my kettle, have a steamer rack on the bottom (so I don't scorch the bag or grain) with a chain going up to the handles so I can pull it out after the mash. I like it a lot.  Today will be my first time doing full volume mash.  The last 2 batches I did partial volume mashes, like I used to with a cooler setup.
Brew in a bag is a kick ass method. Oh, and I do 3 gallon batches, so it suits me pretty well.

beerlord:
I  don't get caught up on efficiency since I have my BIAB down but every now and again I check and am usually between 78 and 83%. I'm very pleased with my beers as are all my beer-snob friends.
