Monsooned Malabar is one of the few coffees defined entirely by post-harvest treatment, and it exists because of a shipping accident of history.
The origin
Green coffee shipped from India to Europe in wooden sailing ships spent months in humid holds, arriving swollen, pale and mellow. When steamships and modern packaging removed that exposure, European buyers complained — they had come to prefer the aged character.
So Indian producers began reproducing it deliberately.
The process
After normal processing, green beans are spread in open-sided warehouses on the Malabar coast during the south-west monsoon, from June to September, exposed to humid winds for twelve to sixteen weeks.
They are raked, turned and repacked repeatedly. The beans absorb moisture, swell to nearly double, and fade from green to pale gold.
The result
Almost no acidity at all, very heavy body, and an earthy, musty, spiced character with notes of tobacco and nuts.
It is genuinely unusual and genuinely divisive. Specialty buyers often dislike it; it has a devoted following in espresso blending, where its body and lack of acidity are useful.
Brewing it
Espresso, or a heavy immersion brew. Medium-dark roast. A pour-over wastes it — there is no acidity for a clean brewer to reveal.
