Is this an infection?

[darkrabbit]

Hi, trying to figure out if this white stuff on top of my fruit (blueberry) is an infection or just pellicle? It's not all over the place just in spots. Fruit wasn't 'sanitized' but it was frozen fruit. Just wanted to see what the consensus is...

Thanks

Is this a sour beer with living bacteria and/or wild yeast? Most would consider a pellicle a type of infection. I can't really tell from the photo.

Sorry, yes it's a sour, kettle sour. I thought a pellicle forming was normal....

The white patches on the fruit are a pellicle (as long as they aren't hairy or fuzzy).

Unpasteurized fruit is covered with wild microbes.
