India Coffee Harvest Season: A Roaster’s Buying Calendar
Most roasters who source Indian green coffee know that the harvest happens sometime in the winter. Fewer know the specific windows by region and variety, when fresh crop actually arrives in market, how long the freshness window lasts, or when to start conversations with their importer to secure the lots they want.
This post answers those questions with data rather than generalities. The goal is a practical buying calendar that a roaster can use to plan Indian sourcing across the year, understand when they are getting fresh crop versus near-past-crop, and know when to act.
The Basic Structure of India’s Harvest
India’s coffee harvest is driven by the monsoon cycle. The southwest monsoon, which brings the main rainfall from June to September, drives cherry development. The northeast monsoon, active from October to December in Tamil Nadu and parts of Karnataka, provides additional rainfall in those regions. Cherry maturation follows the dry, cool months after the monsoon retreats – which is why harvest runs from November through March.
Two species, two timelines:
Arabica harvest runs from November to January. Arabica cherries ripen faster than Robusta and are more delicate, requiring timely picking to avoid over-ripening on the tree. In most Karnataka and Tamil Nadu growing regions, the main Arabica picking period is December, with early and late lots bracketing that central window.
Robusta harvest runs from December to February, extending to March in some regions. Robusta cherries require more time to mature than Arabica. The extended harvest window also reflects the larger volume – mechanised harvesting or strip picking is sometimes used for lower-grade Robusta lots to manage the labour requirement across a longer season, while specialty Robusta producers continue selective hand-picking through February.
One important nuance: high-altitude estates harvest later than low-altitude estates within the same region. Cooler temperatures at 1,200 to 1,500 metres slow cherry development by two to four weeks compared to lower-altitude blocks. A roaster evaluating a high-altitude Somwarpet Arabica lot should expect it to be harvested in late December or early January, while a lower-altitude Coorg Robusta block may peak in November or December. This altitude effect on harvest timing is rarely documented on green coffee bags but is relevant to freshness dating.
Region by Region: Harvest Windows
- Arabica: November to January, peak December
- Robusta: December to February, peak January
- Notes: Somwarpet Taluk Arabica (higher elevation) peaks later, typically late December to January. Robusta in Madikeri, Virajpet, and Ponnampet taluks begins earlier.
Chikmagalur, Karnataka
- Arabica: November to January, peak December
- Robusta: December to February
- Notes: Higher-elevation Bababudangiri blocks peak later. Chikmagalur is almost entirely Arabica in the specialty segment.
- Robusta: December to March
- Notes: Wayanad’s harvest extends later than Karnataka’s due to its position in the northeast monsoon shadow. Adivasi smallholder lots are often processed as natural and take longer from harvest to dry mill readiness.
- Arabica: November to February
- Notes: High-altitude blocks at 1,500 to 1,800 metres harvest later – January to February. Lower blocks begin in November. The Nilgiris receives both monsoons, which means a longer growing season and a correspondingly extended harvest window.
- Arabica: November to February
- Notes: Harvest period at Thandikudi and surrounding areas runs November to February. Chandragiri and Selection 9 varieties have slightly different ripening rates on the same farm.
Araku Valley, Andhra Pradesh
- Arabica: November to January
- Notes: Tribal smallholder lots at higher elevations peak in December. The Araku harvest is well-documented and arrival timing is more predictable than some less-established origins.
From Harvest to Processing: The Timeline at Origin
Harvest is the beginning of a timeline that roasters need to understand to plan accurately.
Selective hand-picking – the method used on all specialty lots in India – extends the harvest over four to six weeks per estate as pickers return to the same trees multiple times as different cherries reach peak ripeness. A lot described as “December harvest” on a Coorg estate may represent cherry picked across a five-week window from late November to early January.
Processing duration varies by method:
- Washed: depulping, fermentation, and drying typically take 10 to 20 days in good conditions
- Honey: 8 to 12 days drying for yellow honey, 12 to 20 days for red or black honey
- Natural: 20 to 30 days sun-drying for whole cherry
Dry milling and grading – hulling, polishing, grading, and sorting at the dry mill – adds 1 to 3 weeks depending on the facility and volume.
Rest at origin – specialty lots are typically rested in hermetic bags or grain pro for 30 to 60 days post-processing before shipping. This rest period stabilises moisture and allows the green coffee to settle after the stress of processing. Lots shipped immediately after processing without a rest period are at higher risk of inconsistency in the cup.
Export documentation and loading – Coffee Board of India export registration, quality inspection, phytosanitary certification, and booking the container add 1 to 3 weeks before the ship departs.
The result: a cherry picked in December is realistically ready to ship in February at the earliest for washed lots, and March or April for natural or honey lots with rest periods.
Ocean Freight: From Cochin to Your Warehouse
The primary export port for Indian specialty coffee is Cochin (Kochi) in Kerala. Most Karnataka and Tamil Nadu lots transit to Cochin by road before loading. Some Karnataka lots also ship from Mangalore or Chennai, but Cochin handles the majority of specialty green coffee volume.
Transit times from Cochin to major importing markets:
- Canada (Toronto/Vancouver): 25 to 35 days via container ship, typically routing through one transhipment port (Singapore, Colombo, or Port Klang)
- UK/Northern Europe: 20 to 28 days direct or 25 to 35 days via transhipment
- East Coast USA: 20 to 30 days via Suez Canal routing
- Australia: 15 to 25 days
These are shipping time estimates only. Port congestion, container availability, and booking lead times add additional weeks. During peak export season – January to April – when Indian coffee volume is highest and competing with other Asian origins for container space, booking 2 to 3 weeks ahead of desired loading date is advisable.
LCL (Less than Container Load) shipments, which are common for specialty buyers purchasing less than a full container, consolidate with other cargo and typically add 1 to 2 weeks to transit time due to consolidation logistics.
The Fresh Crop Arrival Window
Putting harvest, processing, rest, and shipping together, the realistic arrival window for fresh crop Indian coffee in major consuming markets is:
Washed Arabica (Coorg, Chikmagalur, Nilgiris, Palani Hills)
- Harvest: November to January
- Ready to ship from origin: February to March
- Arrival in Canada/Europe: March to May
- Peak freshness window: March to September of the harvest year
Honey and Natural Arabica
- Harvest: November to January
- Ready to ship from origin: March to April
- Arrival in Canada/Europe: April to June
- Peak freshness window: April to October of the harvest year
Robusta (Coorg, Wayanad)
- Harvest: December to February
- Ready to ship from origin: March to May
- Arrival in Canada/Europe: April to June
- Peak freshness window: April to November of the harvest year
These windows have direct implications for menu planning. A roaster who wants fresh crop Indian Arabica on their menu in January is sourcing near-past-crop from the previous year’s harvest. The freshest Indian green coffee in any given year arrives in market between March and June.
When to Book: The Allocation Calendar
The most important date in the Indian coffee buying calendar is November. This is when:
- Harvest is about to begin or has just started on early-picking estates
- Pre-harvest samples from the current season are beginning to circulate
- Producer conversations about volume and pricing for the season are happening
Roasters who make sourcing decisions in November – based on pre-harvest samples from the same farm and variety combination in a previous year – secure the best lots before they sell. Waiting until March or April, when fresh-milled samples are available, means competing with other buyers for what remains.
The practical booking calendar for roasters sourcing Indian green coffee:
- September to October: Contact your importer or sourcing partner. Discuss which lots, farms, or regions you want to prioritise for the coming season. Confirm your volume requirements.
- November to December: Review pre-harvest samples if available. Place allocation commitments for the lots you want. This is especially critical for small-volume specialty lots – micro-lots from individual farms sell out before they ship.
- January to February: Confirm your order once the harvest is underway and processing has begun. Pre-shipment samples should be available from washed lots. Request samples before confirming payment.
- March to May: Fresh crop arrives in market. Evaluate arrival samples. Begin roasting with the season’s new crop.
- June to September: The freshness window for Arabica from the current season. Robusta holds slightly longer due to its denser bean structure.
- October to November: Near end of freshness window for Arabica. Begin sourcing conversations for the next season.
Freshness, Past-Crop, and What to Look For
Green coffee does not last forever. The freshness window for Indian specialty coffee is:
- Arabica: Peak flavour within 6 to 9 months of arrival. After 12 months from harvest, acidity begins to fade, brightness diminishes, and the cup starts to read woody or papery.
- Robusta: Holds slightly better due to its lower lipid content. Peak within 9 to 12 months of arrival. After 15 months from harvest, quality degradation becomes noticeable even in well-stored lots.
The tell-tale sign of past-crop Indian green coffee is a bluish-green bean colour turning brown. Fresh Arabica from India should appear bluish-green with good moisture content of 10.5 to 12 percent. Beans that have turned brown, regardless of the stated harvest date, are past their peak.
Water activity reading is the most accurate freshness indicator for lots where documentation is available. A water activity above 0.65 warrants caution. Below 0.60 suggests over-drying.
When evaluating green coffee against a harvest date claim, count from the harvest date rather than the arrival date. A lot that arrived in May from a January harvest has already been green for four months before it reached your warehouse. The freshness clock started in January, not May.
How Indian Harvest Timing Fits Your Annual Sourcing Calendar
For roasters managing a multi-origin programme, Indian coffee arrives in a window that fills a gap in the annual sourcing calendar. The main arrival period – March to June – follows the peak East African and Central American arrivals of January to April and precedes the Brazil and Indonesian arrivals of May to September.
This means Indian coffee can serve as a seasonal bridge in a roaster’s offering – arriving fresh when Ethiopian and Kenyan main-crop lots are becoming past-crop and before South American new crop fully arrives.
For roasters in Canada or Australia where Indian origin is still relatively uncommon, fresh crop Indian Arabica arriving in April to May offers a genuine point of differentiation – both in cup character and in origin story – at a time when the specialty market is transitioning between seasons.
Practical Checklist for Sourcing Indian Coffee Fresh Crop
When confirming a purchase of Indian green coffee, request the following documentation:
- Harvest date (month and year of cherry picking, not processing date)
- Processing completion date (when the lot finished drying and milling)
- Shipping date (date of loading at Cochin or other port)
- Moisture content at time of export (should be 10.5 to 12 percent)
- Water activity reading if available
- Bag type (hermetic bags or grain pro retain freshness significantly better than standard jute or sisal)
- Storage conditions at origin and in the importing warehouse
These data points tell you where the lot sits in its freshness timeline and whether the handling has been appropriate. A sourcing partner who cannot provide harvest date and moisture content is not managing the supply chain at a level that supports specialty quality claims.
