THE SHORT ANSWER
Arabica and robusta describe plants. Washed and natural describe processing. Light and dark describe roasting. Espresso describes brewing. Latte describes a drink. A single coffee can belong to all five conversations at once.
1. Start with the plant
Arabica (Coffea arabica) and robusta (Coffea canephora) are the two commercially dominant coffee species. Neither name alone tells you whether a particular bag will taste good. Variety, farming, processing, roasting, and brewing all matter.
| Label | What it tells you | What it doesn’t promise |
|---|---|---|
| Arabica | A coffee species with many cultivated varieties. | Automatic quality, sweetness, or a particular flavor. |
| Robusta | The common name for Coffea canephora; often used in blends and also sold on its own. | That it is merely a cheap substitute. Quality varies. |
| Variety | A more specific plant identity, such as Bourbon or Caturra. | A flavor that ignores where and how it was grown. |
2. Find the place on the bag
“Single origin” points to one stated source, but the source can be a country, region, cooperative, estate, or lot. Read the details rather than assuming every single-origin bag comes from one farm. A blend combines coffees toward a desired cup profile. Blends can be every bit as thoughtful as a single origin.
Origin is a beginning, not a tasting guarantee. Two coffees grown in the same country can be strikingly different. Our coffee atlas puts a little context behind the place names.
3. Follow the fruit after harvest
Fruit is removed before the final drying stage; fermentation and washing are often involved.
The coffee dries inside the whole cherry before the dried fruit layers are removed.
Some sticky mucilage remains while the depulped coffee dries. It does not mean honey was added.
Parchment is removed while the bean still holds more moisture than in conventional dry hulling. It is a processing term, not a brewing method.
Processing affects the cup, but “natural” does not guarantee fruitiness and “washed” does not guarantee mildness. Treat tasting notes as an invitation to notice, not a checklist you must pass.
4. Pick the roast by taste
Lighter roasts commonly emphasize a coffee’s brightness and origin character. Medium roasts often balance that with more roast-developed sweetness. Darker roasts tend toward deeper, roast-led flavors. Naming is not standardized across all roasters, so one shop’s “medium” may look darker than another’s.
“Espresso roast” means the roaster designed it with espresso in mind; it is not a separate species or a fixed darkness. A darker color also isn’t a reliable caffeine meter.

5. Know your cup
| Drink | Built from | Start here |
|---|---|---|
| Espresso | Finely ground coffee, hot water, machine pressure. | Espresso guide |
| Americano | Espresso plus hot water. | Make an Americano |
| Latte | Espresso, generous milk, a little foam. | Make a latte |
| Cappuccino | Espresso and textured milk, usually smaller and foamier than a latte. | Make a cappuccino |
| Flat white | Espresso with fine microfoam; café sizes vary. | Make a flat white |
| Cortado | Espresso softened with a smaller amount of warm milk. | Make a cortado |
| Cold brew | Coffee extracted in cool water over hours. | Cold brew guide |
| Iced coffee | An iced serving style, commonly hot-brewed coffee cooled over ice. | Compare the two |
A better way to choose a bag
Start with what you enjoy: fruit and brightness, chocolate and balance, or a deeper roast. Then choose a grind that suits your equipment. Buy an amount you can use while it tastes lively. You don’t need to memorize a glossary before breakfast.
Flavored coffee has flavorings added; a tasting note such as “chocolate” can describe a coffee’s natural sensory impression without chocolate being an ingredient. Check the actual ingredient information if that distinction matters to you.
