Coffee Is an Agricultural Product

Most people treat coffee like a pantry staple — something that exists on the shelf year-round, interchangeable from bag to bag. But coffee is a fruit. It grows on trees, ripens in seasons, gets picked, processed, dried, shipped, and roasted before it ever reaches your grinder. Each step takes time, and that time is tied to a calendar.

Understanding coffee seasonality is one of the most practical tools a home brewer can develop. It tells you when a given origin’s coffees are at their freshest and most vibrant, when to stock up, and when to look elsewhere. It also explains why your favourite Ethiopian roast might taste different depending on when you buy it — you may be tasting two different harvests.

Why Coffee Has Seasons

Coffee cherries ripen over months, not days, and they are typically harvested once or twice per year depending on the country and altitude. After harvest, the cherries are processed — washed, naturally dried, or honey-processed — and then the green (unroasted) coffee is dried further, milled, sorted, and bagged for export.

From that point, the green coffee travels. Ocean freight from Ethiopia or Kenya to a European or American port takes four to eight weeks. Then the importer receives it, cups it for quality, and releases it to roasters. The roaster orders a batch, roasts it, and offers it for sale. From harvest to your bag, the typical journey is three to six months for most origins.

This means that when a roaster advertises “fresh crop” coffee, they are referring to coffee from the most recent harvest — not coffee roasted yesterday. Fresh crop is the opposite of old crop, last year’s harvest that has been sitting in a warehouse losing brightness and complexity with every passing month.

Harvest Calendar by Major Origin

No origin is harvesting every month of the year, but the global spread of coffee-growing regions means that somewhere in the world, there is always a harvest underway. Here is when each major origin’s coffee is typically at its freshest on roasters’ shelves — accounting for processing and shipping time.

Ethiopia (October – January harvest; arriving at roasters roughly March – July)

Ethiopia is the birthplace of coffee, and its harvest — concentrated in the highlands of Yirgacheffe, Sidama, Guji, and Gedeo — runs from October through January. Processing adds a few weeks, shipping adds another four to six. The freshest Ethiopian lots typically land with importers and roasters between March and July.

This is when to seek out Ethiopian coffees. You will find natural-process lots with the most vivid blueberry and jasmine notes, and washed lots with their characteristic clean lemon, bergamot, and floral brightness. Ethiopian coffee purchased between August and February may be old crop — it will not be bad, but the high tones will have mellowed.

Colombia (main crop October – December; fly crop April – June)

Colombia is unusual among coffee origins because its diverse topography — two major mountain ranges with opposing weather patterns — produces two distinct harvest windows per year. The main crop runs from October through December; the smaller fly crop (mitaca) runs from April through June. Both are of high quality.

Freshest Colombian coffees arrive on shelves roughly January through April (main crop) and July through September (fly crop). Colombians from regions like Huila, Nariño, and Antioquia offer red fruit sweetness, caramel body, and bright acidity at peak. This staggered calendar means fresh Colombian coffee is available more often than most origins — a useful anchor when other origins are in their old-crop gap.

Kenya (main crop October – December; fly crop June – July)

Kenya produces some of the most coveted specialty coffee in the world, and its auction system means exceptional lots are highly sought by roasters globally. The main crop harvest runs October through December; a smaller fly crop follows in June and July.

Fresh Kenyan coffees hit roaster shelves roughly January through April (main crop) and August through September (fly crop). This is when the characteristic blackcurrant, tomato, and bright citric acidity are most vivid. Kenyan coffee that has lingered past its window loses precisely those high-frequency flavors first — the cup goes flat and the famous brightness dulls.

Guatemala (December – March harvest; arriving at roasters roughly April – July)

Guatemala’s harvest runs December through March, concentrated in regions like Huehuetenango, Antigua, and Acatenango at high altitude. Fresh Guatemalan lots arrive with roasters roughly April through July.

At peak, Guatemalan coffees offer milk chocolate, brown sugar, stone fruit, and a full body that suits both filter and espresso applications. This is one of the more forgiving origins for freshness — the flavor profile tends toward sweetness and body rather than delicate florals, so it holds up slightly longer than more aromatic origins like Ethiopia or Kenya.

Brazil (May – September harvest; arriving at roasters roughly September – January)

Brazil is the world’s largest coffee producer, and its harvest runs May through September — the opposite end of the year from East African origins. This is not coincidental: Brazil sits below the equator, where seasons are inverted relative to the Northern Hemisphere.

Fresh Brazilian coffees arrive on roaster shelves roughly September through January. At peak, expect nutty, chocolatey, low-acid profiles with a creamy body — the classic character of natural-process Brazilians from Minas Gerais, Sul de Minas, or Cerrado Mineiro. Brazilian coffee is a staple in espresso blends precisely because its profile is robust and its freshness window is broad.

Costa Rica (November – March harvest; arriving at roasters roughly April – August)

Costa Rica’s main harvest runs November through March, with some micro-lots from higher altitudes extending into April. Fresh Costa Rican coffees typically reach roasters April through August.

Costa Rican specialty lots — particularly from regions like Tarrazú, Naranjo, and the West Valley — offer bright citrus acidity, clean sweetness, and a light-to-medium body. The honey and natural process coffees from Costa Rica’s innovative micro-mills often show tropical fruit character at their freshest.

Indonesia (year-round, with regional peaks)

Indonesia is the exception to most seasonality rules. Because it straddles the equator with diverse growing islands — Sumatra, Sulawesi, Flores, Java, Bali — there is no single harvest window. Different islands harvest at different times throughout the year.

Sumatran coffees, often wet-hulled (a process called giling basah), are available year-round and change character more slowly than washed lots. Sulawesi and Flores coffees peak at different months. The practical upside: Indonesian coffees are among the most reliably available regardless of what else is in season. Their earthy, full-bodied, low-acid character suits drinkers who want consistency rather than the fleeting brightness of peak East African lots.

Old Crop vs. New Crop: What Changes in the Cup

Green coffee does not spoil in the way that fresh produce does, but it does age. Over twelve to eighteen months in storage, green coffee loses moisture, undergoes subtle chemical changes, and gradually becomes what the trade calls “old crop” or “past crop.”

The changes are cumulative and one-directional:

• Bright, volatile aromatics fade first. The top notes — florals, citrus, berry — are the most fragile. An Ethiopian that once smelled like jasmine may smell like dried herbs a year later.
• Acidity rounds and diminishes. The crisp brightness characteristic of Kenyan or Colombian washed coffees softens to something flatter.
• Body becomes heavier and woodier. Old crop coffees often taste heavier but less complex — the balance tips toward dull sweetness and woody notes.
• The roasted character becomes more dominant. With less going on from the green coffee, what you taste is primarily the roast.

None of this is catastrophic for commodity coffee, which is blended and roasted dark enough that origin character matters less. But for specialty coffee — where you are paying for the flavors grown into the bean — old crop is a meaningful downgrade.

How to Track Fresh Crop Arrivals

The best way to know when fresh lots are landing is to pay attention to the people who handle them.

Follow specialty roasters you trust. Good roasters announce new crop arrivals, often with notes on when the coffee was harvested, processed, and received. Instagram, newsletters, and product pages are the primary channels.

Read importer updates. Importers like Falcon Specialty, Mercanta, Nordic Approach, and Collaborative Coffee Source publish regular updates on what is new in their warehouses. These posts reflect what roasters will be buying in the coming weeks.

Note the harvest year on the bag. Some roasters print the harvest year (e.g., “2025 harvest”) alongside the roast date. When the harvest year on a bag flips to the current year, that is fresh crop.

Ask your roaster directly. A good specialty roaster will tell you whether a given lot is fresh crop or old crop — and many will volunteer this information in their tasting notes.

A Practical Seasonal Guide

• January – March: Excellent time for Kenyan and Colombian (main crop). Ethiopian fresh crop beginning to arrive. Brazil wrapping up old crop; new crop not yet landed.
• April – June: Ethiopian fresh crop peak. Costa Rican fresh crop arriving. Colombian fly crop beginning. Good window for East Africa generally.
• July – September: Colombian fly crop peak. Kenyan fly crop. Brazilian fresh crop beginning to arrive. Ethiopian starting to age — transition to Colombian or Costa Rican.
• October – December: Brazilian fresh crop at its freshest. Colombian main crop beginning. Ethiopian and Kenyan harvests underway — lots from this year not yet available, so buy accordingly.

The goal is not to obsess over windows to the point of anxiety. Even well-stored old crop coffee is worth drinking. But if you are buying single-origin specialty coffee and want the flavors the grower, processor, and roaster worked to preserve — buy in season.
