Coffee is one of the most consumed psychoactive beverages on the planet. It’s a cornerstone of culinary identities the world over. Nearly every country, region, and culture has its own unique way of preparing and consuming coffee. But there’s nothing simple about a cup of coffee. Those beans in your kitchen are the sum total of a complex series interactions between international corporations, roasters, shippers, marketers, wholesalers, and even the growers who put the seeds in the ground. It’s complicated. It’s a mess.
Below are some of the most common coffee myths and misconceptions to help you become a more informed consumer of this deliciously bitter elixir.
Coffee isn’t a bean. It’s a seed! Technically, it’s the endosperm (pit) of a special kind of berry typically from the Coffea Arabica plant. Initially, it’s wrapped in a thin red fruit that’s peeled off during the cleaning process. Then it’s a light silvery green color until it’s shipped and roasted—eventually reaching your kitchen counter.
Unfortunately, that doesn’t mean you can plant your coffee beans and grow your own coffee trees. The beans we grind up and brew are not plantable anymore due to the roasting. Even if they were, it can take years before a coffee plant is mature enough to produce the berries that contain the coffee bean. Not to mention, coffea arabica (the most popular cultivar of coffee) only grows and thrives in a few places in the world. It’s a demanding little plant with very particular climate needs—which brings us to our next point.
Coffee beans don’t grow in Europe. They grow in Central and South America, East and West Africa, the Arabian Peninsula, Asia, and Hawaii. So if you’re buying expensive imported coffee from Italy, France, or anywhere that’s not one of these regions, you’re likely getting pretty bad coffee (unless you live in Italy or France, that is). That’s because the best tasting coffee is always roasted shortly before it’s consumed.
If your coffee beans say they’re from Ethiopia, it means that’s where the beans were grown, not that’s where they were roasted. But if your coffee beans say they’re from somewhere in Europe—since we know beans don’t grow there—it likely means the coffee was roasted there and that’s bad (again, unless you’re in Europe). Roasting brings out the flavors in coffee, but those flavor compounds start to break down shortly after they’re roasted. Coffee roasted outside your locale has likely been sat in a shipping container or cargo plane for god-knows-how-long. So when it arrives, all those flavors that make the coffee so tasty when you’re sitting in a Parisian cafe have greatly degraded.
That’s why my advice is to always buy locally roasted coffee beans and grind them at home (with a burr grinder).
We often hear that darker coffee is “stronger” or contains more caffeine, and that’s not strictly true. When green coffee goes into a roaster, it’s literally just toasted to different levels of doneness—just like your morning toast.
Blonde roasts are among the lightest roasted beans, and because they don’t spend as much time cooking they actually contain more intact caffeine compounds than medium or dark roasted beans. Heat accelerates chemical interactions which means it also breaks down caffeine compounds. So it stands to reason that the longer a coffee bean is roasted, the less caffeine it’s going to contain when it’s ground up and brewed.
