How much foam from Yeast?

Recommended Posts

I have 2 batches of beer fermenting now. In a Mr Beer 2 Gal Keg fermenter. 1st is American light, 2nd is Czech Pilsner.

The American light had sooo much foam it came out of the lid(despite the lid being very tight).

The Czech Pilsner has barely any foam.

 

Is something wrong with either brew, or is this normal?

 

Thank you

I used the same distilled water for both brews, and did the brewing exactly the same way. No temperature changes.

Maybe something was wrong with one of the yeast packets?

I have the same "big foam" from a Czech Pilsner (6th day).  I haven't had the issue before so will wait and see.

The lid has vents in it designed to let out the pressure.  Making it "tight" has no impact on these vents.  

 

You should NOT be using distilled water.  See your other post asking about water.  Distilled water did not impact the krausen, but can impact the taste.

Every batch is different. Some will have lots of foam and some will have very little. Yeast are living things just like people. We are all different.

Distilled water is the last water you should be using. It has no minerals. Yeast need minerals.
