How the Coffee Market Works, From Grower to Roaster
Coffee is one of the most widely traded farm goods in the world, and almost none of it is grown where it is drunk. Between a hillside in Minas Gerais and the machine in a break room there are growers, exporters, importers, roasters and distributors, and each one hands the price to the next with a delay. This post follows the coffee along that chain and marks where the market stands at the end of September 2026, using the July 2026 report from the USDA and the futures price on 29 September 2026. It is a snapshot. Every figure names its source and its date, and the market will have moved by the time you read it.
Who Grows the World's Coffee
The USDA's Foreign Agricultural Service forecasts world production for the 2026/27 crop year, which runs from July 2026 to June 2027, at a record 189.7 million bags of 60 kilograms. That is up 10.8 million from 178.8 million the year before. Records in Brazil, Ethiopia, Uganda and Vietnam more than offset losses in India and Indonesia.
Brazil is far ahead of everyone else, and the next tier is smaller than most people expect. Vietnam is forecast at a record 32.5 million bags, up 800,000, on expanding area and higher yields. Colombia is forecast at 13.4 million, up 900,000 after a year of excessive rain. Ethiopia reaches a record 12.1 million, and Honduras 6.0 million, up 500,000. Indonesia moves the other way, down 1.0 million to 11.4 million, because heavy rain disrupted flowering in its lowlands.
Why One Hillside Matters
Brazil grows nearly 40 percent of the world's coffee and, depending on where it sits in its two-year cycle, 40 to 50 percent of the world's arabica. More than 70 percent of that arabica comes from a single state, Minas Gerais. Arabica alternates between heavy on-years and lighter off-years, and in normal conditions an on-year crop can rise by 5 to 10 million bags and then fall by a similar amount the year after. The terrain is uniform, so a frost, a hot spell or a drought does not hit one farm. It hits a large area at once. The USDA's reading is that these swings account for most of the year-to-year variation in world arabica supply, which is why weather in Minas Gerais is the first thing the market watches.
The recent record shows how hard the swings can be. In 2021/22 drought and heat cut Brazil's off-year output by 13.3 million bags, and the on-year that followed recovered only 3.4 million because of frost, heat and below-average rain. A later rebound lagged expectations because of excessive rain, and two consecutive years of decline from drought and heat came after that. For 2026/27 the USDA forecasts Brazil at a record 71.9 million bags, up 8.9 million. Arabica rebounds 9.5 million to 47.5 million after five years of weather-related underperformance, while robusta eases to 24.4 million. Timely rain during flowering in September and October gave near-record yields in Minas Gerais.
What Growers Do When Prices Are High
High prices are a signal, and growers respond to them, though never quickly. Vietnam is the clearest case in this year's report: recent high prices let growers spend more on fertilizer and other inputs, and yields rose. Ethiopia replaced more than half of its cultivated area with higher-yielding varieties over four years. Better care can lift a crop within a season. New trees cannot, because a coffee tree takes years to bear, so a decision to plant today shows up in the market long after the price that prompted it. That gap between the signal and the supply is the reason coffee prices swing as far as they do.
The Cushion Between the Crop and the Cup
Between a harvest and a cup sits inventory. World ending stocks, the coffee held over at the close of a crop year, fell 15.5 million bags between 2020/21 and 2024/25, as weather-hit Brazilian crops left the world short. Ethiopia, Mexico and Peru raised their arabica output to fill the gap, but the USDA notes that these gains did not fully compensate for Brazil's losses.
The same report has stocks rising for a second consecutive year, to 26.3 million bags in 2026/27, which is still below the long-term average. A rebuilt cushion is part of the reason a good harvest does not change what everyone pays overnight. The world first has to refill what it drew down.
From the Exchange to the Roaster
Arabica is priced on the ICE futures market and quoted in cents per pound, and robusta trades on its own contract. Those are benchmarks, not shelf prices. Green coffee, the raw seed before roasting, moves from the grower through exporters and importers to a roaster, priced as the exchange level plus or minus a premium for quality, origin and timing. Roasters usually buy months ahead and carry inventory, so a move on the exchange reaches a roaster's costs gradually, and reaches the end of the chain later still.
We are not a roaster. The coffee we deliver is roasted by New England Coffee in Malden, Massachusetts, or comes from the national brands we carry, which means we watch this chain from the roasting end rather than the growing end. We do not publish our own prices here. This page is about the market itself.
Where the Market Stands at the End of September 2026
On 29 September 2026 ICE arabica futures traded at 292.66 cents per pound, 21.93 percent lower than a year earlier, according to Trading Economics. The USDA's July report showed the same direction from a wider view: the International Coffee Organization's composite price index had dropped 25 percent over the previous 7 months as additional supplies became available.
Behind that is a forecast surplus. The USDA sees 2026/27 production at 189.7 million bags against consumption of 179.7 million, a difference of 10.0 million bags, with the largest consumption gains in the European Union and the United States. Not every agency agrees on the size of the Brazilian crop. Conab, Brazil's national crop agency, puts it at 67.6 million bags, against the USDA's 71.9 million, and the two use different methods.
What a Buyer Can Take From It
A forecast is not a price, and this post makes no prediction about either one. Three things hold up whichever way the market goes. First, supply is expected to be larger than consumption in 2026/27, and that pressure usually works through to buyers gradually rather than overnight, because stocks are still being rebuilt and roasters buy ahead. Second, the risk is concentrated: one region of Brazil sways the whole arabica market, and a frost or a drought there can reverse the picture within a season. Third, what a business pays lags the exchange in both directions, so a better question for any supplier is when its own costs were last reset than what futures did today.
The next USDA coffee report is due on 16 December 2026. Any figure on this page older than that report should be read as a snapshot, not as today's number.
