Can Coffee Actually Be Grown in Florida? What the First University Field Study Found

Florida-grown arabica coffee is not a fantasy — it is now a documented, peer-reviewed reality. The first serious field trial showed average fresh cherry yields exceeding 3 kilograms per plant across four cultivars in South Florida's subtropical conditions. That headline number comes from a University of Florida study published in Crop Science in August 2026, the first formal agronomical assessment of Coffea arabica grown in the southern United States. The results are encouraging, uneven, and full of caveats — which is exactly what you'd expect from a genuinely novel experiment.

The study, titled "First assessment of agronomical performance of Coffea arabica in the southern US conditions," was conducted at the UF/IFAS Tropical Research and Education Center (TREC) in Homestead, roughly 30 miles south of Miami. Researchers germinated 48 arabica plants in 2022, transplanted them to TREC in May 2023, and collected their first meaningful yield and quality data from the 2025 harvest — the 2024 fruit set was too early for representative data.

How Did the Four Cultivars Actually Perform?

The table below summarises what the study found across the four arabica cultivars tested:

Cultivar	Key Trait	Peak Fresh Cherry Yield	Brix (Sugar)	Notes
Typica	Historic cup quality	Not individually reported	~10 Brix (avg.)	Typically modest yields; included for quality benchmarking
Fronton	Disease tolerance, yield	~5 kg per plant (several plants)	~10 Brix (avg.)	Among the more consistent performers
Limani	Disease tolerance	Not individually reported	~10 Brix (avg.)	Less common cultivar; data still thin
Obatã	Yield potential	>6 kg (one plant)	~10 Brix (avg.)	Highest single-plant yield recorded in the trial

The 10 Brix average for soluble sugars is the study's most glaring weak point. Arabica cherries grown in established tropical origins typically register 16 to 20 Brix — a range that correlates with the sweetness and complexity coffee buyers expect in specialty-grade cups. South Florida's warm nights, rocky alkaline soils, uneven rainfall, and the young age of the plants are all cited by the researchers as possible contributors to the shortfall.

Bean size and acidity levels, by contrast, were generally in line with arabica grown in conventional origins — a more encouraging finding suggesting the physical structure of the fruit is developing normally even if sugar accumulation is not.

What Exactly Did the Researchers Test, and Where?

The trial site is the UF/IFAS Tropical Research and Education Center in Homestead, Florida — a facility purpose-built for subtropical and tropical crop research. Homestead sits at the southern tip of the Florida peninsula, where winter temperatures are the mildest in the continental United States and the climate most closely approximates the subtropical band in which arabica can theoretically survive.

The cultivar selection was deliberate. Typica is one of the most historically significant arabica varieties in the world, prized for cup quality but not known for high yields. Fronton, Limani, and Obatã are less widely grown but were chosen specifically for traits like disease tolerance and yield potential — characteristics that matter enormously in a new growing environment where pest and disease pressures are poorly understood.

Researchers germinated 48 plants under controlled greenhouse conditions in Gainesville before transplanting them to TREC. That two-year nursery phase is standard practice for arabica, which is a slow-maturing crop. The 2025 harvest represented the trees' first full productive season, and the authors are careful to note that yield variation was high — a single season of data from young trees is not a reliable predictor of long-term performance.

An earlier phase of the broader UF/IFAS research program, reported by TCPalm in January 2024, had planted 150 coffee plants across three sites — Fort Pierce, Gainesville, and Homestead — to determine basic survival and adaptability before the more focused Homestead yield trial was designed. That earlier work established that arabica plants could survive Florida winters in the southern part of the state.

Why Is Florida Such a Difficult Environment for Coffee?

Coffee's ideal growing conditions occupy a narrow band: temperatures between roughly 64°F and 70°F (18°C–21°C), consistent rainfall, well-drained acidic soils, and protection from frost. Florida violates several of these requirements simultaneously.

South Florida's warm nights are a particular problem. Arabica accumulates sugars in its cherries most efficiently when nighttime temperatures drop — a diurnal temperature swing characteristic of high-altitude tropical growing regions like Ethiopia's Yirgacheffe zone or Colombia's Andes. South Florida's nights stay warm year-round, which the UF researchers identify as a likely reason the cherries averaged only 10 Brix.

The soils around Homestead are rocky and alkaline — the opposite of the slightly acidic, well-drained volcanic or loamy soils that arabica prefers. Nutrient management in these conditions is more complex and expensive. Rainfall is uneven, with a pronounced wet season followed by a dry winter that doesn't map neatly onto the moisture patterns arabica evolved with.

Then there is freeze risk. Even short periods in colder conditions can be lethal to the plants, according to NOAA data cited in the earlier TCPalm coverage. Homestead is the safest location in Florida for this reason — freeze events are rare but not impossible — which is why the TREC site was chosen over Fort Pierce or Gainesville for the yield trial.

Corresponding author Felipe Ferrão, a UF/IFAS research assistant who has been central to the broader Florida coffee research program, framed the challenge plainly in 2024: "The main challenge is the temperature and the weather — the freeze events we have here."

What Did the Study Say About Economics?

The Crop Science paper includes a preliminary economic modeling section — unusual for an agronomical field trial — signaling that the research team is thinking beyond pure plant science. The authors do not claim commercial viability or scalability at this stage. The most promising near-term paths to commercialization they identify are farm-to-table and agrotourism models.

This framing is consistent with how specialty coffee has developed in other non-traditional US growing regions. California's Kona-adjacent coffee industry — primarily on the Big Island of Hawaii, which is technically a US state but climatically very different from the mainland — has demonstrated that premium pricing, direct-to-consumer sales, and experiential tourism can make small-scale coffee farming economically viable even when yields and volumes are modest by global standards.

Ferrão made a similar observation in the 2024 TCPalm interview, noting that Florida has "the potential for specialized small-scale growers investing in agrotourism and small-batch roasts, like in California." The economics of specialty coffee have shifted dramatically over the past two decades: large plantations now account for a shrinking share of global production, with small farms producing about 80% of the world's coffee, and roughly 94.5% of coffee farms globally being smaller than 12 acres.

A Florida coffee industry, if it develops, would almost certainly fit that small-farm, high-margin model rather than competing on volume with Brazil or Vietnam.

Who Is Funding This Research, and Does It Matter?

The study's funding statement lists Severin Hacker, the co-founder of Duolingo, who is also the founder of Above Ground Coffee, a coffee venture with an apparent interest in domestic US coffee production. The authors, including Ferrão, declared no conflicts of interest.

The funding disclosure is worth noting because it connects academic research to private commercial interest in a way that is increasingly common in specialty agriculture. Hacker's involvement does not invalidate the research — the study was peer-reviewed and published in Crop Science, a rigorous academic journal — but it does suggest there is private capital watching this space closely.

Above Ground Coffee's interest in Florida-grown coffee aligns with a broader trend of entrepreneurs and investors exploring domestic US coffee production as both a sustainability play and a premium differentiation strategy. Whether that interest translates into commercial plantings in the next five to ten years will depend heavily on what subsequent seasons of data from the TREC trial reveal.

How Does This Fit Into the Bigger Picture of Climate and Coffee?

The Florida study is not happening in isolation. It is part of a global rethinking of where arabica can and cannot be grown as climate change reshapes the traditional coffee belt.

A major 2022 study projected that the world's highest-suitability coffee-growing areas could decline by more than 50% by 2050, echoing earlier research warning of broad losses in coffee-growing suitability by midcentury. A 2025 Costa Rica study showed that low-elevation arabica hybrids grown under shade showed promise in the Caribbean lowlands. A 2024 Brazilian study explored using high-elevation robusta as an arabica replacement in existing coffee lands.

The Florida research fits into this pattern as a geographic expansion experiment rather than a climate adaptation experiment — asking whether arabica can colonise new territory in the northern hemisphere rather than whether it can survive in its existing territory as conditions worsen. Both questions matter, and they are increasingly intertwined.

Ferrão put the stakes plainly in 2024: "We are talking about a crop that is consumed by over 2 billion people a day," with the United States being the world's largest consumer. The pressure to find new growing regions, develop more resilient cultivars, and improve production efficiency on small farms is not academic — it is existential for the global coffee supply chain.

What Are the Realistic Next Steps for Florida Coffee?

The Crop Science study is explicit that it does not propose immediate commercial viability. What it establishes is a baseline: arabica can survive and produce fruit in South Florida under managed conditions, yields in the first productive season are in a range that warrants further study, and the primary quality limitation — low sugar development — has identifiable potential causes that future management interventions could address.

The researchers' own stated hypothesis is that "coffee can be successfully cultivated under subtropical conditions of South Florida, provided that the appropriate management practices are implemented." That conditional clause is doing a lot of work. The management practices needed — soil amendment to address alkalinity, irrigation scheduling to compensate for uneven rainfall, nutrient programs calibrated to rocky limestone soils, and shade structures to moderate nighttime temperatures — represent real costs that have not yet been fully modelled.

More seasons of data are essential. Coffee trees are perennial, and their yield and quality typically improve as they mature. The 2025 harvest data comes from trees in their first productive year; industry experience in established origins suggests that arabica trees reach peak productivity between years five and ten. The TREC trial will need to run for at least another three to five years before the yield and quality picture becomes clear enough to support serious economic modelling.

Cultivar selection will also evolve. The four varieties tested — Typica, Fronton, Limani, and Obatã — were chosen based on available knowledge about disease tolerance and yield potential, but they were not specifically bred or selected for Florida's particular combination of warm nights, alkaline soils, and freeze risk. Future trials may incorporate cultivars developed through the broader UF/IFAS coffee genetics program, which has been working on disease-resistant arabica varieties using genomic tools.

What Does This Mean for Coffee Drinkers and the Specialty Market?

For specialty coffee buyers and enthusiasts, the Florida study is a data point rather than a market signal. Florida-grown coffee is not going to appear on retail shelves at scale in the next few years. What is more likely in the near term is small-batch, farm-direct coffee sold at a significant premium — similar to the model that has made Hawaiian Kona coffee a recognisable (if expensive) category.

The 10 Brix sugar reading is the number that matters most for cup quality. Specialty coffee is defined in the industry as coffee scoring 80 points or above on the Specialty Coffee Association's 100-point scale, and sugar development in the cherry is one of the key drivers of the sweetness, fruit character, and complexity that push scores above that threshold. Until Florida-grown arabica can consistently produce cherries in the 16–20 Brix range, it will struggle to compete on quality with established specialty origins.

That said, provenance has its own value in the specialty market. "Grown in the continental United States" is a story that resonates with consumers who prioritise domestic sourcing, and the agrotourism angle — visiting a working coffee farm in South Florida — has genuine appeal in a state that already draws tens of millions of tourists annually.

What Are the Key Takeaways From the Study?

The UF/IFAS Crop Science study is the first peer-reviewed agronomical field assessment of arabica coffee grown in the continental United States under subtropical conditions. Four findings stand out.

Arabica coffee can survive and produce fruit in South Florida. This was not a given before the trial, and establishing it is a genuine scientific contribution.

First-season yields — averaging over 3 kg of fresh cherry per plant, with individual plants reaching 5–6 kg — are in a range that justifies continued research. They are not, by themselves, evidence of commercial viability.

Sugar development is the primary quality gap. At 10 Brix against a benchmark of 16–20 Brix, the cherries are producing significantly less soluble sugar than arabica grown in established origins. The causes are likely multiple and partially addressable through management.

The most realistic near-term commercialisation path is farm-to-table and agrotourism, not commodity or even specialty export production. Florida coffee, if it develops, will be a premium niche product sold on provenance and experience rather than volume.

The broader significance of the study lies in what it represents for the global coffee industry: a serious, funded, peer-reviewed attempt to expand arabica's geographic range in the face of climate-driven contraction of traditional growing regions. Whether Florida becomes a meaningful coffee origin in the next decade remains uncertain. That researchers are now asking the question rigorously — and getting publishable answers — is itself a development worth watching.
