FG too high?

[boyracer]

Hey all.
I have a Triple X stout that appears to have stalled fermenting. FG is steady on 1026. Og 1058.
23 L batch @ 17.5 degrees. Day 10 in Fermenter. Rehydrated before pitching with plenty of action.
Has my yeast (nottingham) gone too sleep?
Should i give it a stir? re-pitch? Bottle it?
Never had anything read that high before.
Nottingham usually gives me a <1016 FG.

the couple of times I have had a really stuck brew I have just given it a gentle swirl and upped the temp a few degrees and its come good

last one was a saison that was at 1010 for 5 days. Not too high , but high for the recipe. I swirled and it got down to 1001 in 2 more days

What are you using to measure your FG?
Hopefully a hydrometer.
A refractometer does not accurately measure FG.You need to use a correction table.

Yes, A hydometer reading.
I've given it a swirl, and upped temp to 20 degrees. Check again in morning.

Did you happen to add any cocoa powder or other additives? Once had a choc stout with drinking chocolate added (ran out of cocoa powder) and the sediment threw out my hydrometer readings.

If its the one I am thinking of I made this a couple of months ago as all grain, the recipe asked for 11 g of dried yeast Brewers Friend told me 18 gram.

^^Thats it.
Guess i misread the 1023 FG bit... Just started wearing glasses and don't generally wear 'em in the shed.
Interesting read on starters. I have never made a 2 litre starter with 200 Gm of malt over 2 days!
I usually pitch into 1 or 2 cups of cooled boiled water (30 deg) with a little sucrose added.
Guess i've got a lot to learn...
Thanks lads.

Sounds like its close to done.

You mentioned getting 1016 using nottingham. That's quite high for such a highly attenuating strain. How are you measuring your mash temps? Maybe they are higher than anticipated?

 

[boyracer]

That was the highest numbers i have written down in my brew data handbook. Single digits = better. From memory that was an early experiment in partials.
I am thinking my next investment might be the esky mash 'tun'. I usually do in the oven at 60-65 in lidded SS vessel. I have a thermometer probe in it to keep it below 68 usually. Batteries were flat this brew.....

 

[boyracer]

Tried one last night. After upping temp with no action i left it for 2 more days then bottled at ~1026 FG. I guess the possible higher mash temp as suggested was to blame?
Tastes fantastic..even wife likes it and she isn't a stout drinker usually. Loads of coffee, good retention and pleasing bitterness. Will do this one again.
