How the Indian Coffee Harvest Calendar Varies by Region

India harvests coffee once a year, in the dry months after the monsoon, roughly November to February. Arabica is picked first, from about November to January. Robusta follows from December to February, and some Robusta lots run into March, according to USDA's India coffee reporting.

The common assumption is that each of the regions that make up India's coffee map keeps its own season, and that higher, cooler estates pick months after lower ones. In practice almost every Indian region picks inside the same winter window, and the gap between them is a few weeks. Species moves the dates more than altitude does. Robusta flowers first and is picked last.

When Indian coffee is harvested, region by region

Araku, Koraput, the Nilgiris, the Palani Hills and the Northeast cluster at November to January. All of them grow mostly Arabica. In Araku's G.K. Veedhi mandal, growers describe the Arabica harvest as finishing in December and January, with drying and sorting following straight after.

Karnataka's districts run longer, November to February, because they grow both species in quantity. Chikmagalur is India's largest specialty origin by ICB listings, and Coorg carries more Robusta by planted area than its specialty shelf suggests. A Karnataka "harvest season" is really two overlapping ones.

Wayanad and Baba Budangiri start later, around December, for different reasons. Wayanad is about 95% Robusta. Baba Budangiri's Arabica grows high on a single ridge, where cooler temperatures slow ripening.

Why the window shifts by region

The harvest date is fixed seven to eleven months earlier, when the first pre-monsoon rains trigger flowering. The Coffee Board's crop insurance rules define the blossom window as 20 February to 5 April for Robusta and 1 March to 30 April for Arabica. A normal blossom needs about 20 mm of rain in seven days for Robusta and 25 mm for Arabica, per the Board's scheme documents. "Backing showers" of around 12 mm, falling between the 18th and 40th day after the blossom, are needed to set fruit. When the bloom comes in one burst, the cherries ripen together and picking is tight. A scattered bloom spreads ripening out and adds picking rounds. So the weather between February and April is the first indication of how next winter's picking will go.

Temperature then adjusts the pace. Cooler sites ripen more slowly, and in the hills, cooler mostly means higher (the mechanism is covered in how altitude affects Indian coffee). The effect can be large where the temperature range is wide. One Brazilian study found an Arabica cultivar needed 205–226 days from flowering to maturity at warm sites and 375–396 days at cool ones. Most Indian growing land sits between about 600 and 1,500 m, a much narrower band, so the regional offsets here are weeks. Baba Budangiri's later start is the clearest altitude effect in the table.

Rain during picking is the third factor. The northeast monsoon usually tails off by December, but unseasonal rain during picking knocks ripe cherry to the ground and stalls drying. Karnataka growers once lost more than a third of a ready crop to untimely rain, and Cyclone Michuang hit Koraput during peak harvest in December 2023. Wayanad's longer wet season leaves a narrow drying window, which is why washed processing dominates there.

The Coffee Board's crop forecasts follow the same cycle: a post-blossom estimate in May–June, a post-monsoon estimate in October–November, and a final estimate in March–April, as USDA's reporting describes.

Arabica vs Robusta timing within the same region

Robusta's blossom window opens about a week before Arabica's, yet Robusta is picked a month or more later. The reason is maturation time. Arabica cherries typically take seven to nine months from flower to ripe fruit, Robusta nine to eleven (CIRAD gives 6–8 and 8–12 months).

This plays out inside single districts. In Coorg, Arabica typically comes off between November and January, while Robusta runs December to February and sometimes into March. In Kerala, research in the IMD's MAUSAM journal puts Arabica picking at December–January and Robusta at January–February. Robusta-heavy origins such as Wayanad and much of Coorg finish picking later in the season than the Arabica hills of the Eastern Ghats and the Nilgiris. It is also why Wayanad, mostly Robusta, sits later in the table than Araku, which is Arabica.

What happens between harvest and a bag reaching a shelf

A bag rarely reaches a shelf in the month its coffee was picked. Several steps sit in between, each covered in more detail in what estates do between cherry and parchment.

Green coffee holds for months, so Indian roasters roast from the last crop all year round rather than in a single post-harvest burst. Export calendars put shipping at March to May after a December–February harvest; domestic roasters generally see new-crop green from around February or March as lots are milled. Some coffee is held on purpose: one Palani Hills listing on ICB states its beans rest about seven to eight months after harvest before roasting. Roast date governs how fresh the cup tastes (roast dates and freshness covers that side). Harvest timing governs which green coffee the roaster has to work with.

Reading harvest timing on ICB

Of 1,590 active coffees listed on ICB as of 14 October 2026, 140 mention the word "harvest" anywhere in their product copy. About 20 state a dated harvest or crop year. Ninety mention hand-picking or selective picking, and none mention strip picking. That is roughly one listing in eighty with a harvest date, which makes harvest timing one of the facts Indian roasters print least often. Picking method shows up in copy only when it is a selling point, so the zero for strip picking says nothing about how much of the catalog was actually strip-picked.

Where a date appears, Indian roasters mostly write it as a split year: "Harvest Year 2024-25" or "Harvest 2025–26". The Indian coffee year runs from October to September, so a crop picked between November 2024 and February 2025 is the 2024-25 crop. Some active listings in October 2026 still state a 2024-25 harvest year; whether that reflects older green coffee or product copy that was never updated, the listing alone cannot show.

New listings reach ICB in every month of the year, not in a wave after the harvest. They follow roaster releases and onboarding more than the picking calendar. The region table above tells you roughly when a coffee was picked. The crop-year line on the bag, where a roaster prints one, tells you which harvest it came from.

For most Indian coffee, then, the picking window is November to February, a few weeks earlier for Arabica and a few weeks later for Robusta. Where a roaster prints a crop year on the bag, that line places the lot in this calendar.
