probably belongs in the home brew forum.... i'd most likely just not worry about it. or much better... get brewing and pitch the yeast!!

Its messy ay! I had the same prob with a 1469 starter I found giving it a good swirl to break up the foam as nessecary till it died down - worked ok

Like Bart says shame your brews not ready to be pitched into!

You can buy an anti foaming product to prevent such things but Im a bit anti that sort of thing...Bloody Anti Chemical Hippys!!

Yeah this is the last of my 1469 top-croppings, been having the same problem 3944 belgian wit, both "true" top croppers from memory. Does the amount of vortex affect the krausen production?

Wish I had the chance to brew during the week, but too much on.

I'll probably stay away from the anti-foam, just make a bit of a yeasty mess at work.

Use a bigger flask next time?

I try to keep mine less than half-filled and figure that all that krausen is made from heaps of lovely yeast waiting to get at freshly chilled wort.

Yeah mate, a lot of good yeast gone to waste, used some of the krausen to make another starter though. I didnt know if you can get bigger than 5 litres? It had settled right down by the time I got there in the morning.

I hadn't realised it was a 5L flask! Wow! I generally don't fill my flasks to capacity with starters so that they have room to expand.

Check out the recommended figures for using a stirplate. For my 50L batches with an OG of 1.048 all that should be needed is about 2L of starter.

I often use Mr Malty for making starters from fresh yeast, this starter was made from harvested top-croppings that were fairly old, so had no idea on viability/concentrations. First two wort additions showed only a litle krausen, then after the third it really took off (possible yeast infection???) only went to 4.75 litres (MrMalty says 5.37 at lowest slurry settings) for 40L of a 1.074 ale.
