What is this stuff in my glass?

[cardfan]

Brewed a single hop ipa and moved it to the keg to carbonate on Monday. I have this stuff (looks like black flecks) floating in my glass. I can't tell what it is and when I try to get it out of the glass it's like it disappears. Beer tastes fine but it's bugging me. Any ideas?

Hop material, yeast, or the cancer.....

Looks like dry hop particles. Careful, you get enough in one bottle and it will gush. Cold crashing can help with those, or putting a hop sack on your racking cane.

Looks like yeast or hop particles.
