Hi All,
Question about this starter - is something wrong with it? I used ~1200ml of water with 104g of DME and ended up having just about exactly 1000ml of fluid after boil and adding some of my washed yeast.

The yeast is WPL400. Is this a known issue with this yeast that it's that happy it explodes at about 24 hours or is there something wrong in here?

This is my 4th starter so far and nothing like this happened before. Did I do something wrong?

That is normal. All of your starters should look like that.

How'd I know from just reading the post title that this thread had to do with wlp400? The yeast is notorious for its need of head space but its one of my favorites. I don't do more then 800-900ml without fermcap.

Ah, thanks guys! The first one of this strain did have a bit of a head but it wasn't this big. My other starters were nothing like this though. It's a 2000ml flask so I thought I'd have had more than enough room for it; i'm glad i used a stopper and airlock on this one cause the foil would have blown off!

I never make a starter without fermcap. Hell just the pain it saves with no boil overs on the stove is worth it, but it keeps the krausen down on the ferment as well.

Not necessarily. I have made 14 starters and only one did that. Using a stirplate often keeps the foam down. Of the 14 about 9 has little or no foam.

You'll find plenty of info on it. Anti foaming agent. Some use it in the main boil as well, but I only use it in starters. Nothing worse than a volcano of wort pouring out of the top of an Erlenmeyer all over the stove top.

hmm ok. I don't have a stirplate and don't use fermcap. Mine are always almost blowing through the airlock/blowoff.

I currently don't use fermcap and I don't have a stir plate. I do oxygenate with pure O2 and use canned starter wort. Wlp400 is the only yeast starter I've had overflow. That Yeast has a crazy personality one minute it will throw a huge head then the next sitting there doing nothing. It is also SLLOOOWWW! but well worth the wait. It makes a mighty fine beer. This is just a theory but I have observed that wlp400 dosent seem to like head pressure while it ferments. I have now been just using the blow off tube believing that its easier for the O2 to excape, though it may not considering I'm not the expert on the subject.
