Ancient Wake Up Call

Caffeine has been an essential part of life in the Americas – for even longer than you’d think. A recent study found residue of a coffee or chocolate-like substance (but different from both), in 900-year-old mug-like containers. The cups are thought to be from Cahokia, a large metropolis around 1050 CE that would have been located around St Louis, Missouri. That morning cup of coffee might be a time-honored tradition.
