What is Monsoon Malabar? The History behind the Most Iconic coffee

September 21, 2026

What happens when coffee meets the Indian monsoon?

The answer is Monsoon Malabar coffee — one of India's most distinctive and unusual coffees. Unlike conventional coffee processing, Monsoon Malabar is deliberately exposed to the humid monsoon winds of India's western coast. This unique process changes the appearance, character and flavour of the beans, creating a coffee known for its mellow, full-bodied and distinctive profile.

But Monsoon Malabar isn't simply coffee from the Malabar region. It is coffee transformed by the monsoon.

What is Monsoon Malabar Coffee?

Monsoon Malabar is a specialty coffee from India that undergoes a unique post-harvest process called monsooning.

During the southwest monsoon, selected coffee is exposed to the moisture-laden winds along India's western coast. The beans absorb moisture from the humid atmosphere, swell considerably and gradually change from their usual green colour to a pale yellow or straw-like appearance.

The process also changes the coffee's sensory character. Monsooned coffees are traditionally known for a mellow, heavy-bodied cup with lower perceived acidity and distinctive earthy, woody and spicy characteristics. The Coffee Board of India recognises Monsooned Malabar as one of India's specialty coffees.

In other words, the monsoon isn't just the setting for this coffee — it is part of the process that creates it.

The History of Monsoon Malabar

The story of Monsoon Malabar goes back to the days when coffee from India was transported to Europe by sea.

Coffee beans travelling on sailing ships would spend weeks or months exposed to the humid conditions of the Indian Ocean. The moisture and monsoon winds affected the beans during the journey, causing them to swell, change colour and develop a distinctly mellow character.

When the coffee eventually reached Europe, the beans were noticeably different from coffees transported under drier conditions. Yet the unusual flavour became appreciated by coffee drinkers.

Over time, what began as an unintended consequence of long sea voyages was recreated deliberately on India's west coast.

Today, the process is known as monsooning, and Monsooned Malabar has become one of India's best-known specialty coffees. The Coffee Board of India describes the traditional story as an early accidental discovery that is now intentionally recreated through controlled exposure to monsoon conditions.

It's a rare example of a coffee tradition born from the journey itself.

How Is Monsoon Malabar Coffee Processed?

The defining characteristic of Monsoon Malabar is the monsooning process.

The process takes place during India's southwest monsoon, generally from June to September, when the western coast experiences intense humidity and moisture-laden winds. According to the Coffee Board of India, coffee selected for monsooning is spread in thick layers in airy warehouses and regularly raked.

The coffee is then loosely packed into gunny bags and stacked with enough space between the bags for the humid monsoon air to circulate.

As the beans are exposed to this atmosphere, they gradually absorb moisture. They swell, their colour becomes paler and their physical and sensory characteristics change.

But this isn't simply a case of leaving coffee outside during the rain.

The beans are regularly moved, bulked and repacked to encourage uniform monsooning and reduce the risk of mould or uneven development. The Coffee Board states that the process can take around 12 to 16 weeks, depending on the process and conditions.

Once monsooning is complete, the coffee is polished, graded and prepared for roasting.

The result is a coffee bean that looks remarkably different from conventional green coffee — larger, swollen and pale — and produces a cup with its own unmistakable personality.

Why Is Monsoon Malabar Coffee So Unique?

Most coffees are carefully protected from excessive moisture after processing.

Monsoon Malabar does almost the opposite.

Here, humidity is deliberately introduced as part of the processing method.

That makes Monsoon Malabar a fascinating example of how climate, geography and processing can completely transform coffee.

It is also why two coffees made from similar varieties can taste dramatically different after processing.

The result is a coffee that tends to be mellow and heavy-bodied, with comparatively subdued acidity and distinctive earthy and spicy notes. The Coffee Board notes that monsooning reduces acidity and creates the characteristic mellow profile associated with the coffee.

From an accidental discovery during long sea voyages to a carefully recreated specialty-coffee process, Monsoon Malabar has become a uniquely Indian expression of coffee.
