This is my first all-grain batch and unfortunately it has developed some kind of growth. It didn't smell like death, actually smelled pretty good, and the samples I have been taking have all tasted good, so I went ahead and bottled it. Just curious what it could be and if I will be looking at a loss with this one.

White Film on Beer in Carboy
Don't worry - your beer is probably fine! Causes
Testing
If not, you just have rogue colonies of yeast on your beer. They may persist until you rack the beer, but should settle upon racking, and will not affect the smell, taste, or appearance of your final carbonated beer. If the beer does smell/taste sour, then unfortunately, your beer has become infected. You'll probably have to scrap the batch. Scrub all equipment thoroughly with cleaner, and sanitize carefully before brewing again. If you ferment in a plastic bucket, ensure there are no scratches in the plastic, as they may harbor bugs. If there are scratches, replace the vessel. |

If it smells good, and tastes good it may not be an infection. However, that looks like a little mold of some sort. Not the kind that will kill you or make you blind. Best advice is to drink the beer before the infection takes over. |

That doesn't look like cause for alarm to me. Give it another whiff if they start growing hairs or turn black/green. I don't think you're gonna take a loss. The beer has great color otherwise, btw. |

It looks like mold to me. I would throw it out, unfortunately. |
