What Is Coffee?
Coffee is a brewed drink made from roasted coffee seeds. Those seeds are usually called “coffee beans,” but they actually begin inside coffee cherries that grow on coffee trees. After the cherries are harvested, the seeds are processed, dried, exported, roasted, ground, and brewed.
That means coffee is both simple and incredibly complex. At its simplest, it is roasted seeds brewed with water. At its deepest, it is agriculture, chemistry, climate, roasting science, brewing technique, and personal taste all in one cup.
The Coffee Plant
Coffee grows on trees or shrubs in tropical regions around the world. The fruit is called a coffee cherry. Inside most cherries are two seeds. Those seeds are what eventually become roasted coffee beans.
Coffee plants are affected by altitude, soil, rainfall, temperature, shade, variety, disease pressure, and farm management. These growing conditions help explain why coffees from different origins taste so different.

How Coffee Is Grown
Great coffee begins on the farm. Before roasting and brewing ever happen, farmers must manage plants, soil, climate, pests, disease, harvest timing, and processing.
Altitude
Higher elevation often means cooler temperatures and slower cherry development. That slower growth can contribute to denser beans, brighter acidity, and more complex flavor.
Shade
Shade grown coffee is grown under tree cover. Shade can support biodiversity, soil health, slower ripening, and more resilient farms.
Disease Pressure
Coffee farms face risks like coffee leaf rust, which can reduce harvests, increase costs, and affect long-term farm decisions.
How Coffee Is Harvested
Coffee is harvested by picking ripe coffee cherries from the tree. The ripeness of the cherry has a major impact on sweetness, acidity, consistency, and defects.
In higher-quality coffee, cherries are often selectively picked by hand. That means pickers choose ripe cherries and leave unripe cherries on the tree to mature. This takes more labor and time, but it can produce cleaner, sweeter coffee.
Strip picking and mechanical harvesting can be faster, but they may mix ripe, unripe, and overripe cherries together. Sorting becomes especially important when cherries are harvested this way.

How Coffee Is Processed
Processing is the step that turns coffee cherries into dry green coffee ready for export and roasting. Processing can dramatically change flavor.
| Processing Method | How It Works | Common Flavor Impact |
|---|---|---|
| Washed Process | Fruit is removed before drying. | Clean, bright, crisp, clear, balanced. |
| Natural Process | Coffee dries inside the whole fruit. | Fruity, sweet, heavier body, sometimes wine-like. |
| Honey Process | Some fruit mucilage remains during drying. | Sweet, syrupy, balanced between washed and natural. |

Arabica, Robusta, and Coffee Varieties
Arabica Coffee
Arabica is the species most commonly associated with specialty coffee. It is often prized for sweetness, acidity, aroma, and complexity.
French Settlement Roasting Co focuses on organic, specialty-grade Arabica coffee.
Robusta Coffee
Robusta tends to have more caffeine, heavier bitterness, and a stronger, more earthy flavor. It is often used in commercial blends and some espresso blends.
Robusta is not automatically bad, but it is different from the Arabica coffees many specialty coffee drinkers prefer.
Coffee Varieties
Within Arabica, there are many varieties. Varieties can affect flavor, yield, disease resistance, plant structure, and farm resilience. This is especially important when farmers face challenges like coffee leaf rust.
Coffee Origins
Coffee origin matters because geography changes flavor. Soil, altitude, rainfall, temperature, variety, processing, and farm practices all shape the cup.
Colombia
Often balanced, sweet, chocolatey, nutty, and approachable with pleasant acidity.
Ethiopia
Known for floral, fruity, bright, tea-like, and expressive flavor profiles.
Honduras
Often smooth and sweet with chocolate, caramel, brown sugar, citrus, or apple-like notes.
Peru
Frequently smooth, clean, chocolatey, floral, creamy, and bright with citrus acidity.
Single Origin Coffee
Single origin coffee comes from one identifiable place, such as a country, region, farm, estate, or producer group.
Estate & Micro-Lot Coffee
Estate and micro-lot coffees offer more specific traceability and can highlight farm-level or lot-level differences.

Coffee Roasting
Roasting transforms green coffee into the aromatic brown beans we grind and brew. Heat changes the coffee’s color, aroma, sweetness, acidity, body, bitterness, and flavor.
Light roasts tend to preserve more origin character and acidity. Medium roasts often balance sweetness, body, and flavor clarity. Darker roasts emphasize roast character, deeper body, and lower perceived acidity, but can become bitter if pushed too far.
Bean density also matters. Dense coffees may respond differently to heat than softer coffees. This is one reason skilled roasting is more than simply choosing light, medium, or dark.

Coffee Flavor
Coffee can taste chocolatey, fruity, nutty, floral, smoky, earthy, bright, smooth, bitter, sweet, or complex. Flavor comes from farming, processing, roasting, freshness, and brewing.
Bitterness
Bitterness can come from roast level, over extraction, stale coffee, wrong grind size, or brewing too hot.
Smoothness
Smooth coffee usually has balanced extraction, good sweetness, lower harshness, fresh roasting, and the right coffee for your taste.
Acidity
Acidity in coffee is not the same as sourness. Good acidity can taste bright, citrusy, fruity, crisp, or lively.
Flavor Wheel
The coffee flavor wheel helps explain tasting notes like chocolate, caramel, berry, citrus, floral, nutty, and spice.
Caffeine
Caffeine depends on coffee species, dose, brew method, serving size, and extraction.
Cupping
Cupping is the professional tasting method used to evaluate coffee aroma, sweetness, acidity, body, balance, and defects.
Coffee Brewing
Brewing is where all the work from the farm, mill, roaster, and grinder turns into a cup of coffee. Small changes in grind size, ratio, water temperature, and brew time can dramatically change flavor.
Grind Size
Fine coffee extracts faster. Coarse coffee extracts slower. Matching grind size to your brew method is one of the easiest ways to improve coffee.
Coffee Bloom
Bloom is the bubbling that happens when hot water first touches fresh coffee grounds. It helps release gas and improve even extraction.
Extraction
Extraction is water pulling flavor from coffee. Under extraction tastes sour or weak. Over extraction tastes bitter or harsh.
Water Temperature
Most hot coffee brews best around 195°F to 205°F. Hotter extracts faster. Cooler extracts slower.
Ratio
Coffee-to-water ratio controls strength and balance. Measuring helps you repeat a great cup.
Troubleshooting
If coffee tastes sour, extract more. If it tastes bitter, extract less. If it tastes weak, check your ratio first.

Freshness, Grinding, and Storage
Coffee freshness matters because roasted coffee slowly loses aroma, sweetness, bloom, and liveliness. Whole bean coffee stays fresher longer than ground coffee because less surface area is exposed to oxygen.
Grinding coffee right before brewing gives you more aroma and better control over extraction. Pre-ground coffee is convenient, but it loses freshness faster.
Store coffee sealed tightly, away from heat, light, air, and moisture. Buy amounts you can use while fresh instead of letting coffee sit for months.
