How to Read a Coffee Bag: A 15-Year Roaster's Guide to the Label — Contour Coffee

How to Read a Coffee Bag: A 15-Year Roaster's Guide to the Label

Eric Bakken

A coffee bag is a small document. It says more than most people read. The front is designed to catch your eye — a name, a design, maybe a tasting note in a font that suggests the graphic designer was well-compensated. The back is where the information lives, and what’s there — or not there — tells you more about the coffee than the front ever will.

I’ve been roasting coffee for fifteen years and putting labels on bags for about that long. I’ve watched people in our Lakewood shop pick up a bag, glance at the name, maybe read the tasting notes, and head to the register. They are reading about 20 percent of what I put there. The other 80 percent is the part that actually matters.

Here’s how to read the whole bag, with a real example: our Colombia Excelso EP.

1. Roast Date — Non-Negotiable

The most important line on the bag is the date it was roasted. Not a “best by” date. Not a “use by” date. The roast date. Coffee is a fresh product. It peaks somewhere between three days and two weeks after roast — enough time for the beans to degas the CO2 trapped during roasting, not so much time that the volatile aromatic compounds that make the coffee interesting have oxidized into flatness.

If a bag has a “best by” date and no roast date, assume the coffee was roasted six to twelve months before that date. Coffee that old isn’t dangerous. It’s just sad. The blueberry in an Ethiopian natural fades, the chocolate in a Colombian flattens, and eventually everything tastes like the bag it came in. Specialty roasters print roast dates. Grocery store brands print “best by” dates. The difference is everything.

“If a bag has a ‘best by’ date and no roast date, the coffee was roasted six to twelve months before that. Coffee that old isn’t dangerous. It’s just sad.”

Every Contour Coffee bag has the roast date printed on the label. I roasted the beans in that bag, on a specific day, in a specific machine, in Lakewood, Colorado. You should know when.

2. Origin — The Where

A single-origin coffee names a specific place. The more specific the place, the more intentional the coffee. “Colombia” is a country — fine, it’s a start. “Colombia Huila” is a department — now we’re getting somewhere. “Colombia Huila, Pitalito, Finca El Porvenir” is a farm — someone chose this specific coffee from this specific producer, and they’re proud enough of that choice to name it.

A blend that simply says “South American Coffee” or “Breakfast Blend” with no origin information is telling you the origins are fungible. The roaster is buying whatever’s cheap and available and roasting it to a consistent flavor profile. That’s a legitimate business model. It’s also not the same thing as sourcing.

Our Colombia Excelso EP lists: Colombia, Huila, 1,300–1,650 meters. That’s specific enough to tell you three things. One: this is Colombian coffee, which means balanced acidity, chocolate, caramel, clean — it’s the reference standard for “coffee that tastes like good coffee.” Two: Huila is one of Colombia’s best growing regions, producing coffees with more fruit and brightness than the central regions. Three: 1,300 to 1,650 meters is high but not extreme — the altitude range that produces dense beans with developed sugars but without the aggressive acidity of ultra-high-elevation lots.

Blends should tell you what’s in them. Our French Espresso lists “South America & Indonesia.” That’s broad, but it’s honest — the components rotate with the seasons, and we’re telling you why. “100% Arabica” with no further detail is the coffee equivalent of a car dealership bragging that the vehicle has a steering wheel.

3. Varietal — The Genetics

This is where the label gets nerdy, and it’s worth paying attention. The varietal is the specific cultivar of the coffee plant — Bourbon, Typica, Caturra, Gesha, Castillo, SL-28. Different varietals taste different in the same way different apple varieties taste different. A Bourbon coffee tastes sweeter and rounder than a Typica from the same farm. A Gesha tastes like jasmine and stone fruit in ways that almost shouldn’t be possible from a bean.

Our Colombia Excelso lists Caturra and Castillo. Caturra is a dwarf mutation of Bourbon — sweet, clean, the backbone of quality Colombian coffee. Castillo is a modern hybrid developed by Colombia’s national coffee research center (Cenicafé), bred for leaf rust resistance. Purists sometimes turn their noses up at Castillo because it has some Robusta ancestry in its lineage, but well-grown Castillo, processed carefully, can produce excellent coffee. The presence of both on the label tells you this is a thoughtful blend of traditional quality and modern resilience.

If there’s no varietal listed, that’s not a dealbreaker — many blends don’t specify, and many Ethiopian coffees are labeled “Heirloom” because they’re a mix of subtypes that haven’t been sorted. But if a single-origin from Central or South America doesn’t list a varietal, I’d wonder why.

4. Process — The How

After picking, coffee cherries have to be processed to remove the fruit and dry the bean. The method matters enormously.

Washed (or wet-processed): The cherry skin and fruit are removed before drying. The bean ferments in water tanks for 12 to 36 hours, then is washed clean and dried. The result: clean, bright, transparent — you taste the bean, not the fruit. Our Colombia Excelso is fully washed, which is why it tastes like chocolate and citrus instead of fermented blueberry.

Natural (or dry-processed): The whole cherry is dried with the fruit still on the bean, for weeks, on raised beds or patios. The fruit sugars ferment and concentrate. The result: fruity, funky, wild — blueberry, strawberry, wine-like complexity. Our Ethiopia Guji Kercha is a natural, and you can taste the difference immediately.

Honey: Somewhere in between — the skin is removed but some or all of the mucilage (the sticky fruit layer) is left on during drying. Costa Rican honey-processed coffees often have a syrupy body and stone-fruit sweetness that washed coffees don’t.

Wet-hulled (Giling Basah): The Indonesian method. The coffee is pulped, fermented briefly, washed, and then hulled while still damp, at about 35 percent moisture. The result: earthy, herbaceous, heavy body. Our Sumatra Mandheling is wet-hulled, and it tastes like a forest floor in the best possible way.

If a bag doesn’t list the process, the roaster either doesn’t know or doesn’t think you care. Either is a problem.

5. Altitude — The Elevation

Altitude is shorthand for density and sugar development. Coffee grown at higher altitudes matures more slowly — cooler temperatures, less oxygen — which gives the cherry more time to develop sugars and complex acids. High-grown beans are physically denser, which means they roast differently and extract differently.

Under 1,000 meters: soft, mild, lower acidity. Most Brazilian coffee grows here. 1,000 to 1,500 meters: balanced, sweet, cleaner. Much of Colombia and Central America. 1,500 to 2,000 meters: dense, bright, complex. The sweet spot for East Africa and the best Central American lots. Over 2,000 meters: rare, intensely bright, sometimes aggressively acidic. Ethiopian and Kenyan lots that need careful roasting.

Our Colombia Excelso sits at 1,300 to 1,650 meters — right in the sweet spot where sugars and acids develop together into the balanced, chocolatey, citrus-bright profile that makes Colombian coffee the benchmark.

6. Tasting Notes — The Signal in the Noise

Good tasting notes are specific. “Blueberry, dark chocolate, jasmine” tells you what to expect. “Smooth and rich” tells you nothing — every roaster on earth describes their coffee as smooth and rich. Smooth and rich are the coffee-label equivalent of “charming personality” in a dating profile.

Specificity signals confidence. If I write “Meyer lemon, black tea, nectarine, honeysuckle” on a bag of Burundi Tangara, I’m making a claim you can test. Brew it, taste it, tell me whether I’m right. Vague notes are a hedge. They let the roaster buy anything and describe it the same way.

Also note whether the notes are origin notes or roast notes. “Blueberry” (Ethiopia Guji Kercha) is origin. “Dark chocolate and caramel” (French Espresso) is roast. “Chocolate and citrus” (Colombia Excelso) is both — the balance that good medium-roast washed Colombians are built for. None of these is better. They just tell different stories.

7. Red Flags

Here’s what makes me put a bag back on the shelf:

  • No roast date. Hard stop. I don’t care how pretty the label is.
  • “Best by” alone, no roast date. See above.
  • Vague tasting notes with no origin details. “Smooth, balanced, rich” and the origin just says “South America.” They’re hiding something, and the thing they’re hiding is probably that the green coffee is cheap.
  • “100% Arabica” as the main selling point. This is table stakes. It’s like a restaurant advertising that their food is made from ingredients.
  • Roast level described as a color rather than a degree. “Medium” is fine. “City+” or “Full City” tell you the roaster thinks about roast in a specific way. “Brown” tells you they think you’re an idiot.

“Good tasting notes are specific. ‘Smooth and rich’ is the coffee-label equivalent of ‘charming personality’ in a dating profile.”

Walk Through a Contour Coffee Bag

Let’s look at our Colombia Excelso EP label end to end. Roast date: printed on the bag, specific day. Origin: Colombia, Huila. Varietals: Caturra and Castillo. Process: fully washed. Altitude: 1,300 to 1,650 meters. Tasting notes: chocolate, caramel, citrus, balanced. Roast level: medium.

Every piece of information on that label is there because it tells you something useful about what’s in the bag. The chocolate and caramel come from the medium roast development. The citrus comes from the Huila altitude and the washed process. The balance comes from the Caturra genetics and the Colombian terroir. Nothing on the label is decoration. It’s all documentation.

A coffee bag isn’t packaging. It’s a report. Read the whole thing, and you’ll know more about what you’re buying than most people ever do. More importantly, you’ll know when a roaster is actually telling you something — and when they’re hoping you won’t ask.
