Coffee lovers often think about roast level, flavor, or brewing methods. But few people stop to consider the long journey coffee takes before it reaches their cup.
From tropical farms to roasting facilities and eventually into homes, coffee goes through several stages before it becomes the beverage millions enjoy every day.
Understanding how coffee is produced can give you a deeper appreciation for the effort and craftsmanship behind every cup.
Where Coffee Comes From
Coffee beans come from the fruit of the coffee plant, commonly called a coffee cherry. The coffee bean itself is actually the seed found inside this fruit.
Coffee plants grow best in tropical climates at higher elevations, where consistent rainfall and moderate temperatures create ideal growing conditions.
Some of the world’s largest coffee-producing countries include:
-
Brazil
-
Colombia
-
Vietnam
-
Honduras
-
Guatemala
-
Ethiopia
Coffee farms are often located in mountainous regions, where cooler temperatures slow the growth of the plant and allow the beans to develop richer flavors.
Harvesting Coffee Cherries
Coffee cherries do not ripen all at the same time, which makes harvesting more labor intensive than many other crops.
In mountainous regions, coffee cherries are usually picked by hand. Workers select only the ripest cherries to ensure better quality.
In flatter regions, harvesting machines may be used to collect the fruit more quickly.
After harvesting, the cherries must be processed quickly to prevent spoilage.
Two Main Methods of Processing Coffee Beans
Once the cherries are harvested, the outer fruit must be removed to access the beans inside.
There are two primary methods used to process coffee beans.
Dry Processing
Dry processing is the oldest method of preparing coffee beans.
In this process, coffee cherries are spread out under the sun and allowed to dry for several weeks. During this time, the fruit shrinks and hardens around the bean.
Once fully dried, the outer layers are removed to reveal the green coffee beans.
Dry processing is common in regions where water is scarce.
Wet Processing
Wet processing uses water to remove the fruit from the beans.
In this method:
-
The outer skin and pulp are removed
-
The beans are placed in fermentation tanks
-
Natural enzymes break down the remaining mucilage layer
-
The beans are washed and dried
Wet processing generally produces cleaner, brighter flavor profiles.
Preparing Coffee Beans for Export
After processing and drying, the beans are known as green coffee beans. At this stage they have not yet been roasted.
The beans are sorted based on:
-
size
-
weight
-
quality
They are then packaged and shipped to roasting facilities around the world.
Coffee exporting countries collectively ship millions of tons of coffee beans each year, supplying cafes, roasters, and retailers globally.
How Coffee Beans Are Transported
Traditionally, coffee beans were transported in jute or sisal sacks made from natural plant fibers.
Today, some exporters also use large plastic containers called super sacks, which can reduce shipping costs and protect the beans during transport.
Once the beans arrive at their destination, they are roasted to develop the flavors we associate with coffee.
From Roasting to Brewing
The final step in the journey is brewing. After months of growing, harvesting, processing, drying, sorting, shipping, and roasting, the coffee reaches a percolator, pour-over, or French press.
For outdoor brewers, a campfire percolator is one of the most direct ways to experience the full character of a well-sourced bean. The repeated cycling of hot water through coarse grounds extracts the oils and compounds developed through every stage of the production process — nothing filtered out, nothing diluted.
COLETTI percolators are made from 18/8 stainless steel and designed to handle direct flame, letting the bean speak for itself.
Choosing the best camping coffee percolator improves brewing consistency outdoors.
Appreciating the Journey Behind Every Cup
COLETTI sources coffee beans roasted by City Market Coffee Roasters in Kansas City. Understanding where beans come from and how they are processed helps explain why freshly roasted, coarse-ground beans produce a noticeably better cup than pre-ground coffee sitting in a bag.
Learning how to make percolator coffee properly can dramatically improve flavor and extraction.
Frequently Asked Questions
Where do coffee beans come from?
Coffee beans come from the seeds of the coffee cherry, a small fruit that grows on coffee plants in tropical regions. The primary growing belt runs between the Tropics of Cancer and Capricorn and includes countries such as Brazil, Colombia, Ethiopia, Vietnam, Honduras, and Guatemala. Altitude, rainfall, and soil composition in each region produce distinct flavor characteristics in the bean.
What are the main coffee processing methods?
The two main methods are dry processing and wet processing. In dry processing, harvested cherries are spread in the sun to dry for several weeks before the outer layers are removed. In wet processing, cherries are pulped immediately and the beans fermented in water tanks before drying. Dry processing tends to produce fruitier, heavier-bodied coffee. Wet processing produces cleaner, brighter flavor profiles.
What are green coffee beans?
Green coffee beans are raw, unroasted beans that have been removed from the coffee cherry and dried but not yet roasted. They are shelf-stable for months and are the form in which coffee is exported globally. Roasting transforms green beans through heat to develop the aroma, color, and flavor compounds that define the coffee in your cup. Lighter roasts retain more of the bean's original characteristics while darker roasts develop heavier, more bitter compounds.
Why is coffee grown at high altitude?
Higher elevations produce cooler temperatures that slow the growth of the coffee cherry. This longer development time allows the bean to accumulate more sugars and organic acids, which translate into more complex, nuanced flavor after roasting. Most specialty-grade coffee is grown above 1,200 meters. Beans grown at lower altitudes in warmer climates grow faster, producing a less complex flavor profile that typically suits commercial blends.
What is the difference between Arabica and Robusta coffee?
Arabica and Robusta are the two most commercially grown coffee species. Arabica accounts for roughly 60 percent of global production and is prized for its complex flavor, lower caffeine content, and smooth finish. It grows at higher altitudes and is more labor-intensive to produce. Robusta grows at lower altitudes, contains nearly twice the caffeine, and produces a stronger, more bitter cup. Most quality camping and percolator coffee uses Arabica or Arabica-dominant blends.
How does roast level affect camping coffee?
Roast level directly affects how coffee performs in a percolator. Medium to dark roasts produce the boldest, most full-bodied cup in a percolator because the roasting process develops bitter compounds that stand up to the repeated hot water cycling. Light roasts can taste thin or sour in a percolator because their delicate floral and fruit notes extract quickly and disappear during extended brew times. For campfire brewing, medium dark is the most reliable starting point.
