US05 not kicking off in berliner

[ianj84]

Hey, so I pitched straight lacto in my berliner, let it sit at about 90 for 2 days. Had a nice big krausen with the lacto. Then pitched wyeast berliner blend, nothing for 2 days. I got worried and pitched some US 05. No activity after another 2 days. It's sitting at 66.

Have I let the lacto get hold of it for too long, making it too hostile for sacc yeast to kickoff ?
Any solutions?

Did you aerate when you pitched the yeast?

Once the wort is sour, it is a hostile environment for the yeast and you need to do everything you can for it. I always pitch high (essentially double what I would for a normal beer) and aerate well at the time I add the yeast.

If you didn't pitch high, and/or didn't aerate, it is going to be slow.
