Caro is a brand of caffeine-free roasted grain beverages. Some consider it a coffee substitute. It is manufactured by Nestlé and was first introduced in West Germany in 1954. It is available throughout Europe as well as other markets including New Zealand and Australia. It is imported to the United States under the name Pero. The name “Caro” sounds like the French word “Carreau”, which translates to “diamonds” in playing cards, as seen in the Caro logo (which is also used on Pero).
