Oktoberfest stalled fermentation help

[schristian619]

2 weeks ago I brewed 10 gallons of oktoberfest. I made a starter of wlp820 with 2 viles and did about 5 step ups of 2 liters each, all seemed well. I let fermentation go for 12 days, then did a diacetyl rest. Today i tested the gravity as i was about to rack to secondary and lager....gravity reading was 1.030! What happened? IS there anything I can do to help this guy finish, or do I just need to try again with a new batch?
recipe was:
9lbs pilsner
7lbs munich
3lbs vienna
1.5lbs caramunich
mashed at 120F for 20 minutes and 148F for 60, no mash out, fly sparged.

Any ideas?

Thanks

I've never done a lager, but here's a similar situation with some recommendations.

based on that thread, it seems like just trying to add additional yeast is my only hope. should I return to lager fermentation temperature after pitching new yeast, or leave at diacetyl rest temp?

I would return to fermentation temps, rouse the yeast and see if it takes off.

In the mean time, I would be preparing another starter to be on the safe side.

cool...I'll try that tonight.

Thanks
