Aeration of Starter,...NOT Wort,...Jamil ?

[Jims]

So this example is for repitched yeast made into a starter.

If I were to make my starter from a white labs tube or wyeast pack would anything change. I would use my stirplate to aerate the starter pitch and then still aerate the batch? Or would aeration of the batch not be needed. Theres got to be some disolved 02 in the 2 liters of starter - is that enough to just pitch and then forget about?

There is A LOT of info on this topic already in the forum. Search for starter, and give yourself an hour

Any opinions on over oxygenating wort w/ O2, particularly when oxygenating at lager temps? I've got ethyl acetate popping up in my lagers and some ales recently, and one common thread seems to be oxygenating with pure O2 at lower temps.

UPDATE:

Hey, I just brewed up a batch of a Racer 5 clone using Eric's method of building up a starter step by step (100, +200, +400, +800ml) and NOT aerating the wort, and 5 hours after pitching there wasn't even a hint of a bubble and the 1500ml of starter I'd pitched had formed a nice layer of sediment on the bottom of the primary,...I was disappointed, but too tired Sunday night to deal with it, i.e. aerate it, and decided to check it in the morning.

When I went to check on it in the morning, it had blown the cap of the 3-piece airlock completely off! I figured I hadn't completely had the cap seated, but still, it was spewing frothy krausen non-stop. I quickly fashioned a blow off tube and left it to gurgle and sputter violently while I went to work.

Figuring it had probably spent all it's energy, I went into check on it after work and "DAMN!" It had filled the 1-liter bottle I'd fashioned as a blow off receptacle and was continuing to spew just as strongly as it had that morning,...I've NEVER had a brew be this violent! Yeah, it's a 1.080 beer so there's a lot there for it to work with, but I've brewed several higher gravity beers and never had this amount of blow off.

I used the proscribed Wyeast 1272 - American Ale II and I'd never used that before,...Maybe that has something to do with it,...but it definitely shocked me how violent it was.

Now Tuesday,...in the morning it had slowed to the point that it wasn't filling 1-liter bottles anymore and I could actually attach an airlock to it, but it was continuing to bubble once per second,...DAMN! Now Tuesday evening, it's slowed to bubble every 10 to 15 seconds and the yeast has returned to form a layer of sediment on the bottom. I'm planning on letting it sit in the primary for 10-14 days and then kegging it with the dry-hops as per the recipe,...should be drinkable after a couple of weeks after that I figure,...

In any case, I'm gonna try this again with another recipe,...Hop Rod Rye! and see what happens,...Just thought I'd let you know how it worked for me! Later!

Ryan,

Any news on how that Racer 5 clone is doing?

Ryan,

It's doin' GREAT! It over attenuated (1.006), but that was my bad as I was called out of town for a few days and couldn't crash it in time,...not that I would have checked the FG anyway . I also topped up the carboy a couple of quarts after the boil which accounts for the lower than normal OG-FG. I fermented @ 68F for 10-days and racked/dry-hopped in a secondary for another 8 days,...chilled it to 38F, racked it into a keg with some gelatin to clear it up, and am drinking it right now! It definitely doesn't have the body of the Racer 5, but it's nice and hoppy and the body doesn't really bother me. It's not 'Racer 5' but it's a great IPA. I'll brew this one again paying strict attention to OG and FG,...as well as the blow-off tube

Jamil said, Ignore us and go make beer. Everything will turn out fine.

I agree. Sometimes you just have to brew. Over analyzing things can make you crazy. And I mean crazy.

We all brew for many reasons, one of those reasons is NOT to make our head spin off in frustration.

Yep, beer brewing is not rocket science.............unless you want it to be.
