How to tell if your brew is stuck or finished

[Brewer #41749]

Hi i am just finishing a stout that had a og of 1.061 and I have a reading of 1.030 and i started it three weeks ago i am trying to figure out if it is finished or stuck and this is my third batch. If anyone could help me that would be great

Take gravity readings a few days apart. 1.03 is a very high finishing gravity but it's conceivable, dependent on wort composition, oxygenation or yeast selection. If you take readings a couple days apart and the gravity is still declining, your beer isn't finished. If they're stable over a few days, it is. Can you share the recipe, that will help us diagnose....

I amusing the coopers stout mix with 1 kg of dextrose and maltriose

The second beer I ever made was a Coopers Stout. It was good beer. That should finish out with a lower FG. As N B said check it a couple days in a row to tell if it's still working. There are lots of reasons why it may not be finishing if the reading stays the same. Fermenting temperature or oxygenation are the most common problems. Coopers yeast taught me the reason for using a blow off tube instead of a bubbler on a carboy!
