How to read a coffee bag

Understand origin, process, variety, roast date, and tasting notes before you choose a brew recipe.

Find the roast date first

A roast date tells you when the coffee was roasted. It is more useful than a best-before date, which is often a year away and says little about flavour. Use the roast date to decide whether the coffee needs a few more days to settle or should be brewed soon.

The label gives you a starting point; the first brew tells you what this bag actually does.

Origin is a clue, not a flavour guarantee

Country, region, and farm can suggest growing conditions and common flavour patterns. Processing, variety, roast, and the individual harvest matter too, so two coffees from the same country can taste very different.

Understand the process

Process is how the coffee fruit was removed from the seed, which is the bean. It often shapes the cup as much as origin does.

ProcessWhat happensOften tastes
WashedFruit removed before dryingClean, clear, bright
NaturalDried inside the whole fruitFruitier, heavier, sometimes winey
HoneyDried with some fruit left onBetween the two, often sweet

Variety and altitude

Variety describes the coffee plant, while altitude describes where it grew. Higher altitudes tend to produce denser beans that can taste brighter and may need a finer grind or hotter water. Neither predicts the cup alone, so use them as context for a first recipe.

Roast level needs context

Roast labels are not measured on one shared scale. One roaster’s “medium” may sit closer to another roaster’s light or dark. Look at the colour and taste of the first brew, then adjust water temperature and grind from there.

Dark roasts often extract readily and can taste bitter at a long ratio. Light roasts may need more heat, time, or a longer ratio to taste sweet.

Tasting notes are a map

Tasting notes describe a resemblance, not an ingredient list. “Stone fruit” does not mean fruit was added. Start by asking whether the coffee is sweet, bright, heavy, clean, or drying, then see which note fits.

Keep the roaster’s notes separate from your own. Your note should describe what you tasted with your water, gear, and recipe.

Turn the label into a useful record

Photograph the label, then check the extracted details before saving them. Roastbook keeps the bag beside every recipe and note so you do not have to decode it again.

Common questions

Frequently asked questions

What is the difference between washed and natural coffee?

Washed coffee has the fruit removed before drying and often tastes clean and bright. Natural coffee dries inside the whole fruit and often tastes fruitier and heavier.

Why does the roast date matter?

Coffee changes after roasting. Very fresh coffee can taste uneven while it releases gas, and older coffee slowly loses aroma. The roast date tells you where the bag is in that arc.

Do tasting notes mean flavourings were added?

No. Tasting notes describe flavours the coffee resembles. They are a map for what to look for, not an ingredient list.
