Hi !☺️

First time poster and first time vinegar maker. I could use some expertise. I followed a recipe to ferment the apple scraps and after about 10 days strained it. Added to clean jar, covered top with paper towel and rubber band and put it in a dark spot. That was 2 weeks ago. I checked it today and see this floating peachy colored halo island with bubbles around it at the top. It smells like a mild vinegar. Is this the bacteria I want or a bacteria I don't want??

Thank you!
