Default Can you use actively fermenting wort as yeast starter.

Hi, I'm currently brewing a batch of beer and have made a yeast starter a few hours ago, however i'm unsure of the legitmacy of it... I can't tell if its began fermentation.

I took the original yeast from a previous brew... it had been sitting out for a few hours tho after it had been sipohoned into a keg.

I have another batch fermenting in my chiller right now, so I'm wondering if i could just collect some of the fermenting wort with a turkey baster to use as a yeast starter

any help is reeally appreciated couple mins left on the mash out before we start the boil!!

You're good, use the stuff you made the starter with. When I'm motivated I try to wash my yeast really well and leave it in the fridge. Take it out to warm up a few hours and you're good. Granted, you have a starter's worth of unfermented starter but the yeast is fine. To me, it's about getting enough yeast in there. If you made a starter a day ahead of time and your fermentation starts quick, rock on, but otherwise it'll be just fine.

You can actually skim a decent amount off of the top and pitch it directly into your next batch as long as you have a healthy fermentation going.

A few hours will not effect viability much at all. The sterol content will drop just a little which means it will take a little more time to get going. Same goes for yeast stored for months in the fridge.
