How Is Indian Coffee Processed and What Does It Taste Like?

Ever wondered why some specialty coffees taste unusually mellow, with a muted acidity and a distinct yellowish hue? For coffee lovers exploring unique profiles, Indian coffee — especially those processed through 'monsooning' — offers a fascinating study in how environment and tradition can reshape a green bean beyond recognition.

The key to Indian coffee’s distinctive flavor and appearance lies in the traditional monsooning process, which takes roughly seven weeks. During this time, beans are exposed to high humidity, changing both their color from green to pale yellow and their flavor profile.

What Is Indian Coffee and Where Is It Grown?

Indian coffee is primarily grown in three southern regions: Karnataka, Kerala, and Tamil Nadu. Within these states, the key producing areas include:

• Karnataka (especially the Malabar region)
• Kerala (notably Tellichery and Malabar)
• Tamil Nadu (notably the Nilgiris region)

These high-altitude areas provide ideal conditions for cultivating both Arabica and some Robusta varieties. Indian coffee is officially classified under plantation grades: A, B, C, and T, with A being the highest quality.

Why Does Indian Coffee Undergo Monsooning?

The monsooning process was originally a happy accident. In the past, coffee shipped by sailboat from India to Europe would take several months. During the voyage, beans were exposed to constant high humidity and sea winds, causing them to swell, change color from green to yellow, and develop a muted, earthy flavor. European consumers grew to prefer this altered taste.

When steamships reduced travel time, the market still demanded the same flavor. To replicate the aged effect, producers developed the controlled monsooning method used today.

How Is the Monsooning Process Done — Step by Step?

The monsooning process takes place during India’s southwest monsoon season, typically from June to September, with finishing touches often continuing until February. Here’s how it works:

• Spread the beans: Green coffee beans are spread out in layers 12–20 cm thick in open-sided warehouses.
• Expose to humidity: They are left for five days and regularly raked to ensure even exposure to moist monsoon air.
• Bag and restack: After raking, beans are loosely bagged and piled up. These bags are re-stacked and re-bagged weekly.
• Repeat for 7 weeks: This cycle continues for around seven weeks, allowing the beans to absorb moisture and change both in color and flavor.
• Final sorting: At the end, beans are hand-sorted to remove any that didn’t fully undergo the monsooning effect.
• Export: The resulting beans, now pale yellow and with a unique taste, are prepared for export.

This labor-intensive process results in beans with a larger size, lower acidity, and a distinctive, musty, slightly spicy flavor — often compared to aged wood or paper.

What Does Monsooned Indian Coffee Taste Like?

Monsooned Malabar coffee — especially the AA grade — is known for a very low acidity, heavy body, and flavors that include:

• spices
• woodiness
• paper-like or tobacco-like undertones
• a hint of sweetness
• very little brightness or fruity notes

These qualities make it a popular blender in espresso, especially in Europe and Scandinavia, where it adds body without overpowering other components.

Besides Monsooned Malabar AA, there is also Monsooned Basanically coffee, another regional variation. India also produces some peaberry coffees, though these are less common and not part of the monsooning process.

What Are the Challenges Facing Indian Coffee Production?

Today, Indian coffee faces structural issues:

• Heavy bureaucracy and high taxes
• Limited investment in specialty markets
• Dominance of the India Coffee Board, which controls auctions and often mixes beans from different regions and estates
• This blending erases the unique characteristics of high-quality lots, discouraging producers from focusing on specialty distinctions

In response, the government initiated reforms in 1992, including seed distribution in premium regions. This led to the development of notable lots like Valley Nuggets, which show promise for India’s entry into the specialty coffee market.

Frequently Asked Questions

What is monsooning in coffee?

Monsooning is a traditional post-harvest process where green coffee beans are exposed to humid monsoon winds for about seven weeks. This changes their color from green to yellowish and reduces acidity while adding earthy, spicy, and woody flavors. It originated when coffee shipped by sail to Europe naturally aged during the voyage.

Where is Indian coffee grown?

Indian coffee is grown mainly in the southern states of Karnataka, Kerala, and Tamil Nadu. Key regions include Karnataka’s Malabar area, Kerala’s Tellichery and Malabar, and Tamil Nadu’s Nilgiris mountains. These regions offer high altitudes and suitable climates for Arabica cultivation.

What does Monsooned Malabar coffee taste like?

Monsooned Malabar coffee has very low acidity, a heavy body, and flavors of spice, wood, paper, and subtle sweetness. It lacks bright fruity notes and is known for a smooth, mellow, and sometimes musty profile.

What are the coffee grades in India?

Indian coffee is graded into categories: A, B, C, and T. Grade A represents the highest quality beans, used for specialty and export markets. Lower grades may be used for blends or domestic consumption.

How long does the monsooning process take?

The full monsooning process takes approximately seven weeks. It occurs during the southwest monsoon season, with beans being turned and re-bagged weekly to ensure consistent exposure to humid air.

What is special about Indian coffee production?

Indian coffee is unique for its traditional monsooning process, which creates a low-acid, full-bodied cup with earthy and spicy notes. It is also grown in shaded, high-altitude plantations and includes rare processing methods not widely used elsewhere.
