I was able to capture some wild yeast on petri dishes of DME and gelatin. For the past few weeks I have been growing my starter, which is now ~1/2 gal. Yeast seems to be healthy and tastes fine so far, however I have a really strong creamed corn DMS smell. Is there anything I should/can do to get rid of that before I attempt to pitch this into a real batch. I have learned the importance of boiling for 60 min. and will make sure to do so next time, but can I save this yeast?
