Can you take sg readings after you have bottled and the beer has carbonated?

you would be getting fg (final gravity readings) at this point. So if you don't already have starting gravity (SG) or original gravity (OG) readings (which are diff. names for the same thing), it really won't tell you much (like what alcohol level the beer has). And yes you should be able to do it, but you must make sure that your sample is COMPLETELY FLAT. Any carbonation in the sample will throw it off.

No. You take a starting gravity reading before you start fermenting your wort.

You can take your final gravity reading after fermentation is complete; before bottling or kegging.

Swing from the rafters, shouting those songs
Gone unsung for far too long
