Pero was invented in Germany in the early 1800s, when it became financially infeasible to buy coffee beans.
It's still being produced to this day and is popular with kids and people avoiding caffeine. It wouldn't fool you into believing that you are actually drinking coffee, but it's surprisingly close. If you like coffee flavored beverages, you'll probably like Pero.
It is! My grandparents were obsessed with Pero for years. I thought it was disgusting as a kid. I'd probably love it now.
