I followed a recipe for sake, It called for more sugar during secondary fermentation. It continued to bubble for a few days than quit. I checked the s.g. and it had went from 1.020 before adding the sugar to 1.030 after. It has not changed after a couple of days and seems to have stopped bubbling through the airlock. Is it done or has the fermentation stuck? any help would be appreciated.
unsure of wine

Yep, like John said, try warming it up some, if it is cool. It needs to be about 75F.
Sometimes that added sugar can shock the yeast. Warmed up, if it doesn't start in a few days, you will need to add yeast again. Use the same kind of yeast or at least a high alcohol variety. You should prepare a yeast starter, don't just re-pitch the yeast, that will likely fail.
Slowly, over a period of 4 to 6 hours, add some of the sake to the starter, starting with only a tablespoon-full at a time, working up 1/4 cup at a time by the end. At the end if that time, if the starter is still bubbling away, making sure the starter temperature is within a couple degrees F. of the sake, stir it into the sake.
At 1.030, you still need some oxygen, so when you add the starter, don't be afraid of stirring in some air. Keep the temperature up.

I should add, it will only be done when it reaches the SG the instructions say is the ending SG. However, sometimes these things don't quite reach the specified ending SG, so don't get too nervous if it gets only within .005 or so.
Keep checking the SG. It is more important than bubbles in the air lock.
