Soda starter made from grapes near a road... Safe?

[u/Internal-Homework-39]

Sorry for the background mess, I just want to make sure that this might be safe to consume.

I collected some grapes out of a suburban road, seemed like a road that is not super used but definitely sees some activity probably on the daily.

I used those grapes to make an experimental soda starter and it bubbled like crazy, so I decided to try and make some soda out of it and it actually tastes really good and the fizz is super nice...but the fact it comes from the side of a road makes me a bit unsure if I can down this bottle.

Thoughts?

It's just the starter.

So the soda itself should be fine?

Yeah especially if you keep adding new food for the starter over time
