Carbonating beer with CO2 from fermentation

Hey guys,

I recently had a keg with a leak, so my fully carbed beer went flat with no CO2 left... so it needed to be force carbed some how. I had the idea to do this with CO2 from fermentation. I put about 7L water into a 19L NC-Keg, about 250g of sugar and some bakers yeast (no other yeast on hand at this time) as well as a bit DAP. After one day, I then connected both kegs with my spunding apparatus. After 5 days, my beer is nicely carbed again. No difference in taste so far. Both Kegs went to about 2 bar at room temperature, which is about ideal.

any thoughts about that? Bad or good idea?

cheers

Sounds like about the best one could do to me. Krausening would be my only other thought.

Krausening would be my first thought. Do you have any fermenting beer in the pipeline you can use?

I already finished carbonating the beer ;)
I did krausening in the first place. There were no fermenting beer around in the pipeline, anyway the keg wouldnt fit any more volumes of it as its maximum filled.
