FG at 1.025

One other thing that springs to mind is a Forced Fermentation Test, take a sample after pitching and keep it warm ~ 30c on a stir plate this should show in about 24 hours your potential final gravity, if this is high then it's a brewing issue if it's low then you have a fermentation issue

This sounds like a great thing to try that will at least rule out your brewing technique vs fermentation technique.

There are lots of sites giving advice on Forced Fermentation Testing eg

I will deff try this, thank you

Hi,
I know you said you calibrated your hydrometer but by any chance, have you been using a refractometer for checking your FG?
Just a random thought but that would explain the readings (Assuming the beer tasted "as expected/planned").

Good luck with the investigation!

@jay dee..that would explain a lot

@ hassetbrew, if u are using a refractor without doing a recalc on beersmith tools then ur beers are prob about 1010fg also beer at 1025 would taste quite sweet

[hassettbrew]

@jay dee      yes that does indeed explain a lot ... live and learn eh

[Jay Dee]

Glad that helped.
I'd say it happens to a lot of people when they switch to the refractometer.
Good luck with future brews.

I made the same mistake in the past but my assumption was different. I had a hyrometer as well to get a more believable reading so just assumed my cheapo Chinese refractometer was rubbish.

Great things refractometers once you know what their limitations are, even ones off Aliexpress

[Jay Dee]

I'd say the chinese manufacturing gets blamed for many a dodgey brew!

Here's a very handy calculator for refractometer FG conversion:

@ Jee Dee thanks for that, its a great site too, brew on........

Sean Terrills calc is by far the best and he performed a great experiment getting better actual results than Homebrewers using standard hydrometers, beersmith and others are good too.
