Pitching a fermenting starter.

[jonbomb]

I made a yeast starter two nights ago and it started fermentation yesterday and now today its still fermenting... Can I pitch a fermenting starter??

A-OK. As long as the yeast cells have gone through their reproduction phase, it's a fine idea. You're giving them a good head start since they haven't gone dormant again yet.

+1, pitch away! You can pitch a yeast starter at high krausen, after fermentation is complete, any time in between. You can pitch the whole thing (swirl it up) or wait for the yeast to settle to the bottom, decant, and just pitch the slurry. You can even pour a batch over the yeast cake from a just racked fermenter...but you better use a blowoff. Bottom line, RDWHAHB!!! It is REALLY hard to screw up beer!!!

Pitched the starter last night!! Looks like it started blasting off this morning.

I wouldn't risk it. You'll likely just end up with beer.
