Hey friends,
So I pitched a 5gal batch of IPA about a week and 4days ago. Started with an OG of 1.056, check 5days later and it had a gravity of 1.026. Check again last night (1 week, 4days later) and still had a gravity reading of 1.026.
Would anyone consider this stuck fermentation? I gave my primary a good back and forth to see if it would activate the yeast a little more but not sure if I should be looking at re-pitching…
thanks,
I think we need more info on recipe, process, yeast, fermentation temps.
Post your recipe, yeast amounts/procedure and strain and maybe we can help.
Are you using a hydrometer or refractometer?
US 2 row
crystal malt -10L
light dried malt extract- Briess Pilsen Light
Light liquid malt extract (at flameout)
Wyeast 1056 American Yeast
Started Saturday mashing at all the proper temps (152degrees)
didn’t pitch the yeast until wort was around 68degrees
Had a nice krausen to start and now its settling back in.
stored in basement with temperature around 65-67degrees
Checked Thursday Gravity at 1.026
Waited and checked again the following Weds gravity still at 1.026
Krausen has just about settled back in.
gave it a good swirl today (just grabbing the handle and spinning the bucket back and forth)
hope this helps
using refractometer
We need amounts, or percentages of your fermentables. It could tell us a lot
3.5lbs of the US 2row
1.0 lbs of the crystal malt - 10L
1lb 12oz of the light dried malt extract - briess pilsen light
3lbs 4oz liquid LME
wyeast 1056 American yeast was just a smack pack
then hop additions of course
I’ll bet your issue Is you are not correcting your refractometer reading by using a calculator. I plugged your numbers into Sean’s page and got about 1.010 fg
What about starting gravity? If you’re using a refractometer for taking gravity measurements once there is alcohol in there, you need to run it through a calculator (or work it out yourself if you can find the equation) to work out the actual gravity.
Starting gravity was 1.056 OG, last two have been 1.026. Readings about a week apart with no change
This^^^^^if you are using a refractometer to measure…
Or are you at a 1.026 FG with your hydrometer?
What did you do with the 2 Row?
What I’m seeing is a bunch of unfermentable sugars.
2Row was part of the Mash. I thought I put that in there
3.5lbs of 2Row
and yes, using refractometer for both readings. Its been dialed in using the distilled water method. So I would need to still correct the readings of a refractometer?
Gotcha. Missed that. Check out Stevies reply above for correcting calculations from refractometer readings. It appears that you are just fine.
Refractometers are only accurate PRIOR to alcohol being produced during fermentation which throws them off by quite a bit. If you use the above calculator then you can adjust your post fermentation refractometer reading appropriately.
So Im getting about 3.9% ABV. For an IPA that seems a little low. Or am I getting a different ABV than the group?
When I ran it through the calculator, I got a 1.012 FG, which computed to about 5.96% ABV.
I missed the refractometer part…
Had it been hydrometer and accurate, I would suspect extract and crystal
Im going to admit. Refractometer is a new ‘toy’ for me.
Maybe I should do more homework operating it
