How do they get the flavor in Hint Water?

I've always been curious about how Hint Water manages to infuse such a delicate and refreshing flavor into their water without adding any artificial sweeteners or flavors. I've tried various brands of flavored water in the past, but many of them leave a lingering aftertaste that just doesn't sit right with me. So, how exactly do they accomplish this feat with Hint Water? Is it a secret blend of natural extracts? Or do they use some sort of innovative technology to infuse the flavor? I'm eager to learn more about the process behind this beloved beverage.
