On my latest starter I have had a problem with excessive krausen overflowing the flask. I had not experienced this previously. The only difference between my previous starters and this one is that I ran out of Briess pilsen dme and opened a bag of Muntons extra light. Has anyone else found that they get more or less krausen when switching brands of DME?

Set and forget or with a stir plate? I've never had a noticeable krausen on any of my stir plate starters.

I had to take it off the stir plate due to the amount of krausen.

So, same yeast?
It is a new yeast for me as well, WLP 833. I have used other lager yeasts, as well as many ale yeasts, in the past and have not had this problem.

These two statements don't jive.


I would say biggest differences in behavior would be due to yeast strain, temp, and viability of packaged yeast. I would think most light DMEs are going to behave extremely similarly, everything else equal.

Guess I will know for sure in a few weeks as I plan to use WLP001 for that brew. If I see the same behavior it will likely be the DME, if not, then the yeast.

I always get Krausen when I make starters with belgian yeast. Stir plates make it worse. I would say it is more yeast dependent.

Varies with yeast strain and crucially temperature.

I finally got around to making a starter again last night, and I can now say that it seems my original hypothesis was correct. This time I made a starter with WLP001, a yeast I have made starters with many times in the past. Again, it had a huge krausen that overflowed my flask. I have never had this problem in the past with other brands of light DME and across many different yeast strains.

I guess I will invest in some fermcap.

I used muntons, don't
remember what yeast that was though
Interesting, the new DME I have that is giving me problems is Munton's as well.

I went through a 3 lb bag of a different brand (LD Carlson, I think), which is many starters, without ever having an overflow. Now, the first two starters with the Munton's DME I have had this problem.

Like I said, I think I will invest in some fermcap to solve this problem, but I do wonder if I could solve it as well by just avoiding Munton's DME.

Muntons is pretty good extract though which is why I go for it. fermcap seems like a good solution.
