Shiny swirls on surface of my beer

[Gunshowgreg]

Hey guys I'm not sure if the picture is gonna be of any use cause you can barley see what I'm talking about in my picture. But basically in my bottling bucket I noticed some shiny swirls on the surface of my oatmeal stout. I poured in my priming sugar which I used a corn sugar mix with water and siphoned the beer from carboy to bottling bucket. Not sure if its normal or not. I tasted the beer and it taste fine. Just not sure if this will evolve into s problem latter.

Here is the recipe

Do you use StarSan?

Oil in your ingredients, especially the orange zest.

It's nothing to worry about, whatever it is.

Ginger root too possibly? I'm not sure if I've seen this before but I definitely noticed it today. But if you think it's good. I'll roll with it not much I can do now.

Thanks.

you can get a slight oil film from starsan, and that coupled with the oils that RPh points out, it's easy to see your situation

Sweet that's good to hear. I honestly was worried it was residual oil from my pot that I used for heating my priming sugar. But unrealized it probably would look like that if it was.

Oats also contain oils that will show on the surface like that.
