I have a question ?

Hi, I have a question about a bottle of your product i bought today. It was delicious  as usual, but when I reached the bottom, I found a few small dark pellets I wasn't expcting. I wasn't quite sure what to do with them.

I know coke zero is calorie-free; is it possiblee these are little calorie nuggets that slipped through tha extraction process? If so, I was thinking I might save them for breakfast. That would be a huge time saver in the mornings. Let me know!
