What Is Indian Monsooned Coffee and How Is It Made?

If you’ve ever tried a cup of Indian coffee and found it unusually mild, earthy, and yellowish in color, you weren’t imagining things. There’s a specific reason Indian coffee—especially certain types—tastes and looks so different from other origins. It’s not just about terroir or variety. It’s about a centuries-old processing method that changes the beans’ very profile.

The key factor behind the distinctive character of many Indian specialty coffees is the monsooning process—a deliberate, 7-week exposure to high humidity that alters both color and flavor. This treatment is applied mostly to arabica beans from regions like Kerala’s Malabar Coast.

How I Got Curious About Indian Coffee

I’ll admit, I wasn’t always a fan of anything labeled “Indian coffee.” My mental image of India didn’t exactly include great coffee. But then a friend sent me a sample of Indian volcanic coffee—lightly roasted to first crack, with bright acidity and a clean profile—and it completely changed my view. That led me to dig into India’s coffee history, especially the famous monsooned variety that many coffee enthusiasts talk about but few truly understand.

India’s Coffee Industry Today

India has made big strides in both the volume and quality of its coffee production, especially since market liberalization in the 1990s. Before that, the state-run Coffee Board had a monopoly on exports and often mixed different beans together. After liberalization, individual varieties—both arabica and robusta—started being separated and marketed according to quality. Specialty coffee gained ground, supported by the Specialty Coffee Association of India (SCAI), which includes members with their own farms.

Karnataka is India’s top coffee-growing state, but the finest beans often come from Kerala’s Tellichery region and the Malabar Coast. More recently, coffee farming has spread to northeastern areas like Assam, historically known for tea, giving farmers new income sources.

What Is the Monsooning Process?

Monsooning is what gives certain Indian coffees their unique identity. Historically, coffee shipped from India to Europe by sailboat took months. During the voyage, beans were exposed to constant high humidity and sea winds. By the time they arrived, the green beans had turned a pale yellow and developed a mellow, earthy flavor. European consumers came to prefer this aged profile.

When steamships shortened travel time, the market still wanted that same flavor. So Indian producers recreated the conditions on land. Here’s how it works, step by step:

• Timing: The process runs annually from October to February, coinciding with the natural monsoon season.
• Environment: Coffee is spread out in special open-sided warehouses, in layers about 12–20 cm thick.
• Humidity Exposure: For the first 5 days, the beans are left to absorb moisture from the humid monsoon air. Workers rake the beans frequently to ensure even exposure.
• Bagging & Restacking: The beans are then loosely packed into bags and stacked. These stacks are broken down and rebagged weekly.
• Duration: The entire cycle lasts around 7 weeks. Throughout this time, the beans are repeatedly exposed to humid air, which causes physical and flavor changes.
• Sorting: At the end, beans that didn’t fully absorb the monsoon effect are removed by hand. The rest are sorted, bagged, and exported.

The finished monsooned beans are typically larger, paler, and have a muted acidity with heavy body and a distinct earthy, spicy character. They’re also less bitter than freshly processed beans.

Which Coffee Varieties Are Monsooned?

The monsooning process is applied almost exclusively to arabica beans, particularly those graded as Grade A—the highest in India. While arabica is the focus, some robusta beans from India also undergo monsooning and are valued for their smooth, low-acid profiles, especially in espresso blends. These robustas are especially favored by blenders making strong filter or espresso coffees.

Kerala’s Malabar region is the epicenter of monsooned coffee production, thanks to its coastal location and climate, which naturally support the process.

Frequently Asked Questions

What does “monsooned coffee” mean?

Monsooned coffee refers to coffee beans that have been deliberately exposed to humid monsoon winds for several weeks to mimic the effects of long sea voyages. This process originated when coffee shipped from India to Europe would naturally change in color and flavor due to humidity during the journey.

Why are monsooned coffee beans yellow?

The beans turn pale yellow because prolonged exposure to high humidity during the monsoon process breaks down chlorophyll and other compounds, altering the bean’s color from green to yellowish.

How long does the monsooning process take?

The full monsooning process takes approximately 7 weeks, during which beans are regularly raked and re-bagged to ensure even exposure to humid air.

Where is monsooned coffee produced in India?

Monsooned coffee is primarily produced in Kerala, especially in the Tellichery region and along the Malabar Coast, where the monsoon climate is ideal for the process.

What does monsooned coffee taste like?

Monsooned coffee has a mild acidity, heavy body, and flavors often described as earthy, spicy, and woody. It lacks the sharp brightness of fresh coffee and has a unique mellow profile.

Is monsooning done to all Indian coffee?

No, monsooning is mainly applied to high-grade arabica beans, particularly Grade A from Kerala’s Malabar region. Some robusta beans are also monsooned, but the process is not used for all Indian coffee.
