Origins and producers
Coffee's origin story points to Ethiopia, where legend credits a goat herder named Kaldi with discovering the energising berries. Today Brazil is the world's largest producer by a wide margin, with Vietnam second, and 'which country grows the most coffee' is the single most common coffee question.
Beans and drinks
The two main species are arabica, smoother and the majority of world production, and robusta, stronger and more caffeinated. Espresso-based drink questions ask what's in a cappuccino (espresso, steamed milk, milk foam) or what makes a latte different (more steamed milk, less foam).
Caffeine and fun facts
Espresso has more caffeine per millilitre, but a full mug of drip coffee usually contains more caffeine overall than a single shot, a nuance Bing has tested. International Coffee Day falls on October 1, and Finland is regularly cited as the country that drinks the most coffee per person.
Getting the answers
These are quick lookups: search the exact fact, 'largest coffee producer' or 'arabica vs robusta caffeine', and confirm. If the day's image shows a coffee region or drink, the caption names it and the question usually follows from there.
