Heres the situation : Forgot to take a FG prior to adding priming sugar. NEIPA London 1318 OG: 1.054 FG 8/1/17 (3 days from pitching) 1.012ish FG today 8/12/17 (just got home from vacation) 1.02 Here's what else we know: Used 1.25oz corn sugar to bottle prime 1.75gal Beer temp approx 75 degrees Tried using reminents of sludge and yeasty water at the bottom to get a reading which was all over the place. Is there any formula from the info provided to get an accurate FG?
The carbonated beer after the priming sugar is eaten up will more or less give you what the FG was. Just make sure to pour the sample around a bit and let it sit for a while to flatten it out before taking a reading, because the carbonated sample will throw off your reading.
Did you mean to say that your 8/12 reading was 1.020 or was it 1.002? To go from 1.012 up to 1.020 after 12 days says that one or both of your hydrometer readings are faulty. However, if it was down to 1.002, then you can't get much lower than that, so I'd consider 1.002 as your FG.
Yes it defintely went up so something screwy is going on whether my fault or the hydrometers. Wish I knew which. e
Here's a little more info from my notes: My 8/1/17 sample was from a blowoff popcorn bowl ( 3 ft hose , ripped violently within 12 hours ) sample looked like beer not much yeast mixed in if any. How would that affect things?
I just read this sentence again and realized what you were saying. Using some dregs in your FG reading will cause a high reading if a lot of that stuff was in suspension, so that's why the second reading was higher. I don't know if the typical NE IPA has a final gravity reading that is higher than the typical FG for standard IPAs, but with the extra turbidity of a NE IPA, it stands to reason that it would be. Therefore, your 1.012 reading is probably your actual FG reading because IPAs typically don't get much lower than that without some unusual tinkering with the recipe.
Oh , Well that opens up a new can of worms trying to figure out gravity on NEIPA if I'm reading your last quote correctly. Any thoughts or reading material on that?
No, I don't have any source material; I'm just guessing on that. I have not brewed a NE IPA nor have I looked at recipes to see if their FG would be typically a bit higher.
It's not possible for your specific gravity to fall and then rise again on its own. You either read your hydrometer wrong or had a bunch of trub in your 2nd sample. But don't sweat it, you'll be fine. Your FG probably didn't fall much more than the 1.012 you read on day 3 (maybe a couple points). And according to Beersmith your 1.25 oz of sugar puts you at 2.2 vol CO2, so you're good there too. RDWHAHB.
