INTRODUCTION
TissenBioFarm has tested coffee produced from cultured plant cells. The work matters because it applies cultivated-food methods to a crop facing documented climate and land pressures.
The South Korean cellular agriculture developer handled callus formation, liquid cell culture, harvesting, roasting and extraction with its own system, according to Green Queen. The publication describes the event as South Korea’s first use and tasting of this particular process. That account rests on company claims rather than independent technical data. TissenBioFarm worked with Café Nogales, a Colombian speciality coffee farm, after the organisations signed a memorandum covering research and commercialisation, Green Queen reports. The company says roasting produced intermittent coffee aromas. It is now adjusting culture and roasting conditions while increasing liquid-culture scale, according to the same report. Those steps place the project well before a demonstrated commercial launch. A systematic review published in Plants provides the wider case for looking beyond farmed beans. Its authors found broad evidence of harm to coffee production from climate change. They also found major gaps in methods, regional coverage and analysis. Cell culture may avoid some farm exposure, but neither source proves that TissenBioFarm can match coffee’s flavour, cost or environmental record at scale.
CORE FINDING
TissenBioFarm’s main result is a completed tasting after an internally managed production sequence, according to Green Queen. The company induced coffee callus, grew the resulting cells in liquid, collected the biomass, roasted it and made an extract. Callus is plant tissue formed from cells that have lost their specialised role. Producers can multiply that tissue under controlled conditions rather than cultivate whole coffee plants in fields. TissenBioFarm says the roasted material released aroma at intervals, which it presents as evidence that cultured coffee cells can produce recognisable sensory compounds. Green Queen provides no tasting panel, flavour scores, chemical analysis or comparison with conventional coffee. The report also gives no serving format, batch size, cultivation time or yield. The core finding is therefore narrow. The company has carried cultured coffee material through to a drinkable extract and organised a tasting. It has not shown that consumers would identify the result as coffee or choose it over beans. Nor has it established repeatability. Those omissions do not erase the technical step. They define it.
PROCESS
The route starts with plant cells rather than animal cells, although TissenBioFarm is drawing on tools developed for cultivated meat. Green Queen says the company combines edible biomaterials with biofabrication. Its stated capabilities include edible bioink, food-grade culture materials, lower-cost cell cultivation and a production platform designed to control structure. The company claims its biofabrication system can support very rapid mass production. No independent throughput figures accompany that claim. The underlying technology originated in artificial-organ work at Pohang University of Science and Technology before transfer into cultivated-meat development, according to Green Queen. TissenBioFarm then used it to pursue proteins with controlled texture and marbling. Coffee requires a different outcome. Texture is less central once the cultured cells become roasted material and an extract. Aroma, taste and the chemical effects of roasting take priority. The company says it is refining both culture conditions and roasting. That suggests the tasting tested process feasibility rather than a finished recipe. Green Queen reports that TissenBioFarm is also enlarging its liquid culture operation. The source gives no vessel capacity or target output.
PARTNERSHIP
Café Nogales brings a direct link to conventional coffee production. Green Queen says the Colombian farm and TissenBioFarm signed their memorandum in February before the tasting report. The agreement covers joint research and eventual commercialisation. The source does not disclose ownership of resulting strains, production rights, funding or geographic terms. It also gives no account from Café Nogales about why the farm joined the project. The partnership may provide plant material and coffee expertise, but the stated division of work remains unclear. That matters because cultured products depend on the choice and stability of starting cells. Conventional coffee also varies by species, variety, origin, processing and roast. Neither source identifies which coffee plant supplied the cells used in TissenBioFarm’s tasting. The report offers no evidence that cell culture preserves traits associated with a particular farm or harvest. Café Nogales may help frame the product as coffee rather than a generic roasted cell extract. Yet provenance carries little weight without data linking cultured biomass to the sensory features of its source plant. The memorandum signals intent. It does not settle that question.
CLIMATE CASE
Green Queen presents climate exposure as the main reason to develop coffee away from farms. A separate systematic review in Plants supports the broad concern but gives a more qualified account. The review concludes that climate change is likely to reduce average global yields and diminish suitable coffee land by 2050, drawing on assessments that include the Intergovernmental Panel on Climate Change. It also identifies drought, salinity, biodiversity loss, changing seed access, soil pressure and greater exposure to biological and non-biological stress. Farm vulnerability depends on land size, income, labour, processing infrastructure, market access, bargaining power and access to technical or financial help, according to the review. These factors make climate damage more than a question of temperature. Coffee farms can also provide soil fertility, carbon storage, biodiversity and pest regulation when managed sustainably, the review notes. A cell-culture system could reduce direct dependence on suitable farmland. Neither source measures what would be lost if production shifted away from farms. The climate argument supports research into alternatives. It does not by itself establish that cultured production offers the better environmental outcome.
EVIDENCE BASE
The Plants review examined 148 records on climate change, climate variability and coffee production. Its screening covered research from America, Africa and Asia. Original research made up 74.3% of the selected material, while reviews accounted for 14.9%, according to the paper. Book chapters represented 4.1%. Conference papers and reports supplied another 4.1%, while theses accounted for 0.7%. The literature expanded sharply over time. The review found one relevant article from 1980, compared with 14 from 2019 and 25 from 2020. That rise shows increased research attention, not greater certainty. The authors found that studies often examine individual services or risks rather than the links among yields, ecosystems and livelihoods. They recommend more work on those relationships. This limitation matters to TissenBioFarm’s case. A cultured alternative could change land use, water demand, employment, trade and energy consumption at once. Evidence about declining farm suitability cannot answer whether that replacement system improves the whole balance. Green Queen supplies no lifecycle assessment for the company’s process. The systematic review does not assess cell-cultured coffee.
SPECIES
Commercial coffee rests mainly on two species. Coffea arabica supplies about 60% of traded coffee, while Coffea canephora provides about 40%, according to the Plants review. Research coverage does not match that split. The review counted 75 documents focused on arabica and nine on canephora. Another 34 considered both species, while 30 did not define the species studied. Arabica receives more attention partly because it is widespread across coffee-producing countries and more sensitive to climatic conditions, the review says. Canephora can tolerate higher temperatures somewhat better but reacts badly to cold and may also suffer from greater temperature swings within a season. Large-scale research on its flowering and growth remains limited. TissenBioFarm has not disclosed which species underpins its cultured material, according to the supplied Green Queen report. That gap affects both product identity and climate reasoning. A system based on arabica cells could aim at a large, quality-focused market. A canephora line might present different cultivation behaviour and flavour goals. Without the species, cell line or target drink profile, the tasting cannot show which part of the conventional market the company intends to address.
GEOGRAPHY
The climate evidence also carries a regional imbalance. Of the records included by the Plants review, 90 concerned the Americas, 39 covered Africa and 19 addressed Asia. Brazil led individual countries with 51 records, followed by Colombia with 12. Ethiopia accounted for 17 articles. Kenya and Tanzania had 10 each. Vietnam and Indonesia supplied eight papers apiece. That distribution gives the Café Nogales relationship some relevance because Colombia sits within the better-studied part of the evidence base. It offers less direct support for conclusions about a process being developed in South Korea. The review notes that Asia produced 31.9% of global coffee, yet research from the continent remained limited. Global output exceeded 10 million tonnes across more than 11 million hectares, according to the statistics cited in the paper. The Americas supplied more than 55.5% of production. More than 70 countries grew commercially valuable coffee. A production method detached from climate-suitable regions could alter that geography. The supplied sources provide no evidence about where TissenBioFarm would locate commercial cultivation, where inputs would come from or whether production would remain close to consumers.
METHODS
Forecasts about coffee’s future depend heavily on modelling choices. The Plants review found at least 60 studies using quantitative methods, compared with 13 using qualitative approaches. Seven combined both. Quantitative work included ecological niche models, statistical analysis, economic models and agricultural zoning. Many studies used Maximum Entropy modelling to estimate where coffee could grow under current and future conditions. That method draws predictions from known observations of a species, even when absence data are incomplete. Other studies linked climate and economic variables or combined crop growth, soil, climate and mapping data. Only about three or four papers used process-based models, according to the review. Those models can represent interactions among plants, soil, management and local climate more directly. Qualitative studies used interviews, household surveys, focus groups and document analysis. They added farmers’ experience of weather, pests and adaptation. TissenBioFarm’s project addresses one physical exposure by moving cells into controlled culture. It does not address the social findings in that literature. A commercial shift could protect beverage supply while reducing demand for farm output. Neither source examines that trade-off.
IMPACTS
Most research reviewed in Plants points towards lower coffee output under climate change. Among 42 papers assessing direct effects on yield or production, 35 reported harm. Four found mixed outcomes, while three found gains. Some studies suggested that higher atmospheric carbon dioxide could partly offset heat and drought through a fertilisation effect. The review warns that results vary by place, species and modelling method. Evidence on suitable land follows a similar pattern. Of 54 papers addressing suitability, 33 projected less suitable area or weaker conditions within current production zones. Some studies expected new areas to become viable, including land at higher elevations. Such shifts create their own risks. Potential new zones include forests, protected land and areas already used for other crops, according to the review. Moving cultivation uphill could therefore transfer pressure rather than remove it. Cell culture offers a different route because production need not follow the crop into cooler landscapes. Yet the supplied material contains no comparison between a bioreactor site and farm adaptation. TissenBioFarm has not published energy use, water use, nutrient demand, waste output or land requirements in the Green Queen account.
MODEL LIMITS
The Plants review identifies wide differences in the resolution of climate studies. The models it examined ranged from about one square kilometre to grids spanning roughly 50 to 60 square kilometres. Coarser grids can miss hills, valleys and local shade patterns that shape coffee-growing conditions. Biological responses from pests and diseases may require daily or hourly weather information, the review says. Broad monthly or regional averages cannot capture those mechanisms well. Researchers also gave limited attention to uncertainty arising from climate scenarios, interpolation, model parameters, economic conditions and plant-environment interactions. Some used several models together to reduce dependence on any single result. The review cautions that combining models can still preserve errors from their components. These limits temper claims that a fixed share of coffee land will disappear on a set date. Green Queen cites severe climate pressure and reports that TissenBioFarm wants to bring a plant-cell alternative to market promptly. The academic evidence supports exposure, not a precise commercial deadline. The company’s timetable is undisclosed. So are its regulatory route and the tests that authorities might require before sale.
MARKET POSITIONING
TissenBioFarm is not alone in applying plant cell technology to coffee. Green Queen names Pluri, California Cultured and Coffeesai as other companies working on cell-derived production. Amatera takes a different approach. Green Queen says it uses artificial intelligence and plant cell biology to breed coffee varieties intended to cope better with climate stress. Another group avoids coffee beans while retaining the idea of a brewed alternative. Green Queen places Prefer, Koppie, Voyage Foods, Compound Foods, Atomo, Northern Wonder and Wake in that category. Those businesses use other plant ingredients and, in some cases, fermentation. The approaches answer different problems. Cell culture seeks to retain biological material from coffee while changing how it is grown. Breeding keeps farms and whole plants but tries to improve resilience. Bean-free formulations replace the crop more fully. The supplied sources provide no comparable figures for cost, taste, scale or environmental effects across these options. TissenBioFarm’s experience with cultivated meat may help it handle food-grade cells and structured biomaterials. Coffee competitors may have more specialised knowledge of aroma chemistry and roasting. Green Queen offers no evidence that one route leads on commercial readiness.
UNRESOLVED QUESTIONS
Regulation remains absent from the supplied account. Green Queen does not say whether TissenBioFarm has opened talks with South Korean authorities or classified the product for approval. The report provides no safety assessment, compositional analysis or details of culture media. It does not state whether the cells undergo genetic modification. It also leaves caffeine content unreported. These are material gaps for a drink intended for sale. Production economics are equally unclear. TissenBioFarm describes an ultra-low-cost approach to cell culture, according to Green Queen, but discloses no cost per unit of biomass or cup. The company has not reported productivity, contamination rates or the number of times its coffee cells can divide without changing. Sensory evidence consists of the company’s observation about aroma during roasting. No independent panel, consumer trial or conventional control appears in the source. The counter-argument is straightforward. Conventional coffee already has established farms, processing systems, trading networks and consumer habits. Adaptation, breeding and better farm management may prove cheaper than cultured production. The sources do not permit that argument to be dismissed. They show climatic risk and an early technical experiment, not a settled choice between them.
CONCLUSION
TissenBioFarm has shown that its plant-cell process can reach roasting and extraction, but the evidence stops before product validation. The project will matter commercially only when independent data cover flavour, safety, cost, scale and resource use.
