So, i made a 1L starter from some 3 month old porter slurry. Starter fermented well and was done in about 48 hours on a stir plate.

After 10 hours in the fridge i can see two layers. The starter beer tasted fine for what it is.

Could that top layer be DME protein?

But i'm afraid it got unnoticed.

Forgive me the double post.

Edit: after 3 days it looks exactly the same. Top layer is not compacting that much.
