I do a quick mental guesstimate conversion and get it close then adjust by decimal point additions / subtractions to get it closer. Calculating it exact from the start pobably great too but his works pretty well and is quick for me. Hmm, that might be easier than what I've been doing, so I'll give ...

35.49 (ppg) * .87 (# more grain) / 5.83 (gallons VAW) = 5.29 ; 5.29 * .792 (79.2% efficiency) = 4.14 more points ? Is 79.2% a typical efficiency for BIAB? When I first started looking into all-grain I was seeing ~70% listed as a ballpark. Should I be trying to improve my efficiency (by improving my...

Just had a look at your BIABacus. You have 6.6G in for your mash volume, but that was your SWN as you mentioned above. Oops, I was thinking that was strike water for some reason. I never actually measured my mash volume, but that makes the numbers fit a lot better. With all of this, your VIF is est...

I'm measuring volume with markings I made on my mash paddle. I always measure in the center. I'm not sure my volumes are real accurate, but I have markings every half-gallon, so I should be able to judge down to the quarter gallon or better.

@joshua: I set my grain bag on a trivet, so I'm not worried about it burning, but the first batch was very astringent. I'm guessing since I was heating from the bottom the grain got hotter than 170 ˚F and I extracted tannins. Seems a lot of people do not do a mash-out, so I wasn't sure how necessary...

I don't think I weighed my grains out incorrectly, but it's certainly possible! I'm assuming I had low starch conversion though due to the iodine test coming back positive and my beer being hazy in the keg (likely not protein haze because it doesn't change with temperature; likely not yeast haze bec...

Ah, I see what you mean about batch size! When I was brewing extract I always boiled 3 gallons (cold from the tap), and just topped off to the 5 gallon line in my primary. So I always assumed when a recipe gave a batch size they meant VIF, and never considered they could mean VAW instead. As a parti...

I have BeerSmith 2, so I've included a bsmx file. I also included a bsm file (for BeerSmith 1), but I'm not sure if any settings are lost saving to the old version. I hadn't used BeerSmith before, so I might not have all the values entered (namely I didn't use it for water volumes, but calculated on...

I used BeerSmith for this batch. It's actually the first batch that I've used BeerSmith (used BrewTarget previously), so I'm not entirely sure I had things set correctly. Previously with BrewTarget I've had mash efficiencies of 75% and 73% (efficiency into boil I believe it would be?). I didn't use ...

The beer has been in the keg at 40 ˚F for over a week now. Since the dip tube touches the bottom of the keg anything that settles out should be tapping out first. If it's protein haze it should go away as the beer warms up and the proteins become more soluble, but I'm seeing no change with temperatu...

My predicted OG (calculated at 73% mash efficiency) was supposed to be 1.055 for 5 gallons. My actual OG came in at 1.052. I was expecting a pre-boil gravity of 1.047. Didn't sparge, just squeezed the bag a lot. The FG came out to be 1.009, lower than the 1.012 I was expecting. It definitely is a li...

Help troubleshooting my latest mash; incomplete starch conv.

I've run a few BIAB brews now, changing a few variables here and there to solve some issues that came up. My latest BIAB went fairly well, but I got low mash efficiency (66.8% compared to mid-70's for previous brews). I've read about a lot of things I can try to improve that for future batches, so I...

Hi everyone, I'm from Lincoln, Nebraska in the US. Found this site linked often in other forums I've read. I've been brewing extract for several years and got into all-grain recently. I wanted to find a forum that would be more specific to BIAB brewing. I'm currently a grad student studying chemistr...
