Seed to Cup: A Station-by-Station Guide to What Happens on a Colombian Coffee Farm Tour

The first time you hold a ripe coffee cherry, it's a surprise. It's a small, glossy red fruit, sweet if you bite the skin, with two pale seeds inside wrapped in a slick coating. Those seeds become the beans in your morning cup, but only after a chain of careful steps, most of them done by hand and many of them done on the farm you're visiting. A coffee farm tour walks you down that chain. Knowing what each station is for turns a pleasant walk into something you'll remember every time you brew. This guide follows the order most Colombian tours use and points out what to notice and what to ask at each stop.

Station 1: the nursery and the coffee trees

Many tours start where coffee itself starts: with seedlings. According to the National Coffee Association's coffee education site, young coffee plants are raised in shaded nurseries, watered often and protected from harsh sun until they're strong enough to go into the field. They're often planted out during the wet season, so the soil stays moist while roots take hold.

Then comes the wait. The same source notes that a new tree typically takes three to four years to bear fruit, depending on the variety. Your guide may point out trees of different ages on the same slope, and possibly different varieties. If you're curious about the names you hear, such as Castillo, Caturra or Bourbon, our guide to Colombian coffee varieties explains them.

Look at the slope, too. Colombian coffee often grows on steep mountainsides. UNESCO's description of the Coffee Cultural Landscape highlights farms on slopes steeper than 25%, which helps explain why so much of the work is still done by hand.

Station 2: picking the cherries

This is the station everyone wants to photograph. Coffee cherries ripen from green to yellow to deep red or purplish, and they don't all ripen at once, even on the same branch.

That's why picking method matters. The NCA describes two main approaches:

On steep Colombian farms, picking is done by hand. If you visit during harvest, you may get a basket tied at your waist and the chance to try it yourself. You'll quickly appreciate how skilled the pickers are: moving fast, choosing only the right colour, and keeping their footing on a slope. Not sure if you'll catch the harvest? Check our regional harvest calendar.

Station 3: depulping

Freshly picked cherries can't sit around. Cenicafé, the research arm of Colombia's coffee growers' federation, advises starting depulping right after harvest, and warns that delays of more than about six hours can hurt cup quality.

The depulper (despulpadora) squeezes the seeds out of the skin and fruit. Cenicafé recommends doing this without water, because the natural slippery mucilage on ripe cherries lets the pulp separate with pressure alone. Saving water this way is good for streams below the farm.

What you'll see: a hopper full of red cherries, a machine (sometimes hand-cranked on small farms) and two streams coming out. One is pulp, which many farms compost and return to the soil. The other is pale, slippery seeds still coated in mucilage and a papery shell called parchment.

Station 4: fermentation and washing

After depulping, the beans in Colombia's traditional washed process go into tanks to ferment. This isn't the same as fermenting a drink. The goal is to break down the sticky mucilage so it can be washed off cleanly.

Cenicafé puts typical fermentation at 12 to 18 hours, depending on temperature. Colder, higher farms need longer, while larger batches can go faster. Push it too far and the coffee can pick up vinegary or rancid off-flavours, so timing is a craft.

Ask your guide how they know it's done. Cenicafé describes two classic field tests:

• The rub test: rub a handful of beans together. When they're ready, they feel rough instead of slimy and make a gravelly sound.
• The stick test: push a stick into the mass and pull it out. If the hole holds its shape, the fermentation is complete.

Then comes washing with clean water to strip away the loosened mucilage. Farms may use tanks or channels, and Cenicafé's guidance focuses on doing it with as little water as possible. If you're lucky, your guide will let you put your hands in the tank. It's oddly satisfying.

Station 5: drying

Wet parchment coffee has to dry slowly and evenly. Cenicafé's commercial standard for dried parchment coffee (café pergamino seco) is 10 to 12% moisture. Too wet and it can mould in storage; too dry and quality suffers.

Most small Colombian farms dry with the sun. Cenicafé's drying guide describes several common setups you may see:

Sun drying takes about 7 to 15 days, depending on temperature and rain, according to Cenicafé. The same guide recommends spreading the coffee about 3.5 cm deep and turning it at least four times a day. If you see someone raking a drying bed, that's what they're doing. Some larger operations also use mechanical dryers.

Once dry, the coffee is still in its parchment shell. Removing that layer (hulling), then sorting and grading, usually happens at a mill before export, not on the farm. Our guide to what happens after the tour ends follows the beans from there.

Station 6: roasting

Many farm tours include a roasting demonstration, even though most Colombian coffee is exported green and roasted in the country where it's sold. On the farm, roasting might happen in a small drum roaster, or even in a pan over a fire, to show you how it works.

The NCA's coffee education site explains that beans are kept moving during roasting so they don't burn, and that they begin to turn brown at an internal temperature of around 400°F (about 204°C). That's when the aromatic oils develop. You'll hear the beans crack, smell the change from grassy to toasty, and see the colour deepen. The beans are then cooled quickly to stop the roast.

Station 7: cupping and tasting

The last stop is the reward. Many tours end with a simplified version of cupping, the way professionals assess coffee. Royal Coffee's published cupping protocol, based on Specialty Coffee Association standards, outlines the steps you'll likely follow:

1. Smell the dry groundsFreshly ground coffee in a cup. Breathe in before any water touches it.
2. Add hot water and waitProfessionals use water around 200°F (about 93°C) and let it steep for about four minutes while a crust of grounds forms on top.
3. Break the crustPush the floating grounds aside with a spoon and lean in. This is the strongest burst of aroma you'll get.
4. Skim and slurpClear the foam, then slurp from a spoon. The loud slurp sprays coffee across your palate so you taste more.
5. Taste again as it coolsFlavours shift as the temperature drops. Notice sweetness, acidity and body.

Professional cuppers score coffee on a 100-point scale, and coffee scoring 80 or above is generally considered specialty. You won't be scoring anything, but you'll leave knowing how to taste coffee more carefully. Our guide on what a cupping session really is goes deeper.
