Everything You Need to Know About Coffee Basics

You’ve probably wondered: What exactly is caffeine? How much is in my coffee versus tea? What’s a 'monsoon coffee' and why does it taste musty? Why do some beans cost more just for being round? And what even is a 'hard bean'? If you’ve ever stared at your coffee bag or menu and had these questions pop into your head, you’re not alone.

From the science of caffeine to unique coffee processes like monsoon aging and wet processing, this guide answers the most common coffee questions in straightforward detail—backed by actual numbers, production methods, and industry practices.

What Is Caffeine?

Caffeine is a naturally occurring methylxanthine compound found in over 100 plants, including the leaves, roots, and fruits of coffee, tea, and cacao species. It’s also added to energy drinks and cold/flu medications. Common dietary sources include coffee, cola nuts, and tea leaves. The caffeine content varies significantly by product: for example, 190 ml of tea contains around 50 mg of caffeine—that’s less than a third of the 75 mg typically found in the same amount of coffee.

The average person consumes approximately 3.98 mg of caffeine per kilogram of body weight per day. For a 60 kg adult, that equates to roughly 239 mg daily.

What Is Monsoon Coffee?

Also known as Monsooned Malabar, this is a unique coffee from southern India processed using a traditional, labor-intensive drying method. After harvest, the beans are stored in open warehouses and deliberately exposed to seasonal monsoon winds for 12 to 16 months. This exposure causes the beans to swell to nearly double their original size, turning a dull gold color, while reducing acidity and increasing body. The process results in a mellow, earthy cup with muted aroma but bold flavors reminiscent of roasted peanuts, caramel, and tobacco once brewed. Defective or under-expanded beans are removed during sorting, and only properly monsooned beans are exported.

What Is Shade-Grown or Bird-Friendly Coffee?

Shade-grown coffee develops under the canopy of taller native trees, which provide protection from direct sunlight. This traditional method is common in parts of Mexico, Central America, Colombia, Peru, Venezuela, India, Indonesia, and Africa. The overstory trees also serve as habitat for migratory birds, earning this coffee the nickname “bird-friendly coffee.” Shade-grown coffee often demonstrates better environmental resilience and, in Central America, produces some of the most sought-after flavor profiles. In contrast, sun-grown coffee is cultivated in open fields with little or no tree cover.

What Is Bourbon Coffee?

Bourbon is a natural mutation of the Arabica coffee plant, first discovered on Île Bourbon—now Réunion Island. It has since been widely cultivated and exported to Latin America and Africa. Some of the finest Latin American coffees are derived from Bourbon stock. This variety thrives at elevations between 1,000 and 2,000 meters, where cooler temperatures and longer maturation periods contribute to its balanced, often sweet cup profile.

What Is a Peaberry Coffee Bean?

Peaberry beans, also called caracolillo, are small, round, single-seed coffee beans that form inside the coffee cherry instead of the usual two flat beans. These beans occur when only one seed develops in the fruit, and they are often separated and sold as a distinct grade. Prized for their brightness, higher acidity, and intense aromatic qualities, peaberries are especially popular in the Japanese market and tend to command premium prices.

What Is Wet Processing?

Wet processing, or washed processing, is a method where coffee cherries are de-pulped while still moist. Most high-profile specialty coffees are processed this way to enhance clarity and acidity. In traditional wet processing, the outer skin is removed, and the sticky mucilage is broken down through enzymatic fermentation before being washed away. Modern methods may use mechanical mucilage removal instead. The beans are then dried with a protective parchment layer still attached, which is later removed before roasting. This method is favored for producing bright, high-acid profiles in premium coffees.

What Is the Difference Between Hard and Soft Beans?

Hard beans are grown at higher altitudes, where cooler temperatures slow cherry ripening, resulting in denser, less porous beans with more pronounced acidity and complex flavors. Soft beans are grown at lower altitudes with warmer conditions, leading to softer, more porous beans that typically have milder cup profiles. This distinction is commonly used in the grading systems of Central American coffees, where altitude directly affects bean density and flavor development.

What Is Chicory Coffee?

Chicory is a perennial plant native to Europe, introduced to North America in the 1700s. While its leaves can be eaten, its thick, bitter root is historically known as a coffee substitute. When roasted, chicory root develops a strong roasted flavor similar to coffee but without any caffeine. It became popular during times when coffee was scarce or expensive. Today, some coffee blends incorporate up to 30% chicory to reduce caffeine content while adding bold roasted notes.

Frequently Asked Questions

How much caffeine is in tea compared to coffee?

190 ml of tea contains about 50 mg of caffeine, which is roughly one-third the amount found in the same volume of coffee (around 75 mg).

What is monsoon coffee and how is it made?

Monsoon coffee, or Monsooned Malabar, is Indian coffee exposed to seasonal monsoon winds for 12–16 months in open warehouses. This process swells the beans, reduces acidity, and creates a distinctive earthy, musty flavor with notes of peanut, caramel, and tobacco.

What makes shade-grown coffee different?

Shade-grown coffee is cultivated under the canopy of taller trees, protecting it from direct sun. This method, common in Central America and parts of Asia and Africa, supports bird habitats and often produces more complex, resilient coffees. It is also known as bird-friendly coffee.

What is a peaberry and why is it special?

A peaberry is a rare, round single coffee bean that forms when only one seed develops inside the coffee cherry. These beans are often separated and sold separately, noted for their higher acidity, brighter flavor, and are especially prized in Japan.

What is wet processing in coffee?

Wet processing is a method where coffee cherries are de-pulped and fermented while still moist to remove the sticky mucilage. This process enhances acidity and clarity, and is used for most specialty-grade coffees. The beans are dried with a parchment layer that is removed before roasting.

What defines hard and soft beans in coffee?

Hard beans are grown at higher altitudes and are denser with more acidity and complex flavors. Soft beans come from lower altitudes, are less dense, and typically have milder flavor profiles. This classification is especially used in Central American coffee grading.

Is chicory coffee the same as regular coffee?

No, chicory coffee is made from roasted chicory root and contains no caffeine. It is used as a coffee substitute or blender to add roasted flavor and reduce caffeine content.
