Hello, i have been brewing porter for a while. Since last two batches, when i collect yeast from the bottom of my conical fermentro, i saw a brownish and thinner slurry (instead of a more white and dense one). Is that a sign of a possible contamination o what else? I have not changed any yeast strain (nottingham). Call me a paranoid but I recently had an infection of peddiococus on my plate chiller and i see bugs everywhere

thanks!

The color is probably coming from the wort.  Porter tends to make the slurry look browner than pale ale does.
