I made a starter for the first time and its taking longer than I expected for the yeast to drop out of suspension, so I can decant off the starter wort and pitch just the yeast. my wort is finished and cooled. Will it oxidize the wert if I dont Pitch my yeast right away? Or am I ok not pitching for 12-24 hours? Any one with experience with starters know how long the yeast typically take to drop out of solution in a starter ?

Depending on the type or beer and size of starter it is probably best to just pitch the whole starter. I say this because letting wort sit for that long without yeast is an invitation for bacteria or other baddies to take hold. Or maybe you have some packets of dry yeast available that would do the trick?

Decanting before pitching is really only necessary if you have one or both of a couple of things going on: 1) your starter is huge and would makeup a significant portion of the total volume of the beer 2) you're making a delicate lager or otherwise lower OG beer which may not have the flavor to mask any off tastes from the starter.

Weigh your options, but I would definitely not recommend waiting that long without pitching. I realize that folks who advocate a no-cool method think this is not a big deal and hey ... some fermentations go for up to 72+ hours without activity and still turn out fine, but I would not take that chance.

This is highly dependent on they yeast and it flocculating characteristics. I've had some completely be done and dropped within 48 hours. Other have taken a week.

Next time. Put your starter in the fridge the night before brew day, the yeast will drop to the bottom. Next morning pour off the top liquid but leave enough liquid to mix into the yeast so it can pour easily. Let come to room temp before pitching.

No it won't.

I have done this. No problem. Just make sure you follow sanitary measures along the way.


Another option is pitch the cooled starter, all of it, into your wort. That works very well too!

Good advice, will definitely speed up flocculation, but I've had some take several days even after dropping temps to 40F.

Great point! A few days would be better!

My starter is 1800ml, i feel like thats a lot of crappy starter beer to toss into my fresh wort, but maybe not? I have 5 gallons of robust porter ready to ferment... Im going to pitch asap

That's a pretty average sized starter and only about 10% of your total volume. Plus a robust porter should have plenty of flavor to hide any minor off flavors contributed by the starter. Much of the starter's off flavors will get cleaned up in the main fermentation anyway if you give it enough time.

I think many people that have tried the decant and pitch method didn't know how long it would take. I know the first time I tried I was surprised and frustrated with how long it took. I don't think I've seen much written advice warning how long it might take. Live and learn.

The common case for decanting would be a 4-5 liter starter into a 1.040 Pilsner. Many folks seem to swear by the "just pitch the whole thing at high Krausen" method, but I doubt they are making 4-5 liter starters.

I would pitch the no starter pack or unfinished starter over waiting 24 hours. I may just be paranoid, but I just made a starter with the bottoms of a couple beers and stepped it once both with 15 minute boils. The starter never took and mold started growing after 3 days. So the point is that even when being really careful, wild stuff can still get in and only your yeast will prevent mold and other crap from taking over.
