What did I do wrong here. I brewed in a bag, used the calculations on this site to get my volumes and temps. I ended up with 10 gallons of wort for my 6.6.


So I used the volumes from the site. Mashed for 60 minutes at the 152*. Sparged with the amount it said for 10 minutes. i pressed the grains down to get the wort. so i ended up with 10 gallons of wort?

i took a gravity reading of the 10 gallons i have and it's 1.048 at preboil. but problem is i have 10 gallons, not 6.6? was it the pressing down that i've seen people do with this process, but maybe because they weren't sparging?

i did something horribly wrong on this attempt

look's like you have the per-boil wort from hell. Short time brewing. But, couldn't you evap it down? 1.5g per hour will take some time to do. I read on a thread some were about doing that with 15g down to 6g for a barley wine.

i think where i went wrong is squeezing out the grains. i guess for that calculator it takes into account that you aren't squeezing out the grains.

what i decided to do was make a lower gravity beer as a 10 gallon-ish batch. not what i wanted, but should still be good

...or, you could just toss the extra wort.

At 1.048 pre-boil, you could just boil 6.5 gal down to 5.5 gal somewhere around 1.056; ferment that down to a nice 1.012 or so, and you'll hit a respectable 5.9% ABV.

If I had to guess, I'd say your volumes are off because maybe you squeezed the bag a little too hard? Looks like you got almost all of your water out; I don't BIAB, but just doing straight, bagless all-grain, I plan on losing at least half a quart per pound to grain absorption. You don't wanna waste good wort, but especially if you're sparging, you don't need to wring the grain bag completely dry, either.

I do brew in a bag and I use a simpler method for figuring out how much water. I go pounds of grain x .1 then add that to my desired preboil amount. BIAB absorption is less then standard mashing. I also don't squeeze it much. I usually target 7.5 preboil and end up with 6 after the boil. Then I transfer close to 5.5 to the fermenter. Works out pretty well.

how do you sparge?

I finished with about 6 gallons of 1.068 og. It'll be interesting to see how this one turns out. I went to a 90minute boil and adjusted receipe. I had probably about 2gallons still in kettle that I unfortunately discarded.

I don't usually sparge. To me, that's one of the reasons for doing BIAB. I sparged once when I did a 10 gal batch in my keggle. Couldn't fit all of my grain and preboil water in there so drain the grains and sparged about a gal of water then added it back before the boil. Typically with about 10lbs of grain I will add close to 8 gal of water into my pot, then end up with around 7.5 gal preboil. I also use a hop spider so I don't get as much trub loss.

I have an 11 gallon pot. this recipe had 18.5lbs of grain. would i be able to do the easy sparge method of mash, raise, let drip, heat water to 170, dip grains back in for 10 mins?

if i use the min of 1.25 qts p/lb, i'd need just about 5.75gallons there. plus what another 2gallons for loss? think i'd be able to fit about 8 gallons of water + the grains without it over flowing?

or could i do the 5.75gallons mash, pull grains out, add the other 2 gallons, get to 170, dip back in and sparge?

i tend to like to end with about 5.5gallons of final wort to ferment
