Looks like beer to me! I get bubbles like this after fermentation once in a while and it's fine. No worries, especially if it tastes alright. And if it doesn't taste alright, just leave it in bottles for another month and try it again.
You can't be a real country unless you have a beer and an airline. It helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer. -Frank Zappa
