Climate Change and Coffee Production: How We Keep Quality Stable

Climate Change and Coffee Production: How We Keep Quality, Supply, and Value Stable

Estimated read time: 7 minutes - Last updated 24/02/2026

Climate change is already changing how coffee tastes, how much it costs, and how reliable the supply is. For you, that means two real risks: your favourite coffees becoming less consistent, and prices moving faster than expected. The answer is not “drink less coffee.” The answer is to buy from roasters who can show clear adaptation strategy at origin and disciplined sourcing at the roast level. If you want the full framework first, start with our sustainable coffee guide, then use this page for the climate-specific side. For the wider non-climate footprint view, pair this with our environmental impact guide.

Quick answer: Climate pressure is now a quality and supply-chain issue. We focus on high-altitude resilience, better farm-level adaptation, and transparent buying to keep your cup quality stable.

1) The quality gap: why hotter seasons can make coffee taste flatter

One of the biggest misconceptions is that climate change is only a yield problem. It is also a cup quality problem. As minimum temperatures rise, cherry development speeds up, and faster maturation can reduce quality potential. A major Tanzanian dataset showed night-time temperature as the strongest climate variable linked to Arabica yield decline, with a projected loss of 137 ± 16.87 kg/ha per 1°C increase in minimum temperature.

Recent modelling in Mbinga, Tanzania, reinforces the quality risk: projected warming pushes annual mean temperatures beyond the ~23°C quality envelope for Arabica across elevation zones in the coming decades.

In plain English, this means that the higher heat can compress maturation, and compressed maturation usually means less complexity in the cup. This is why we pay close attention to altitude and climate exposure in our buying decisions. Our African Moon sits at 1400-1800 m.a.s.l., and that cooler night profile is part of how those dark chocolate and cherry notes hold together in the cup.

2) The 2050 map: supply pressure is structural, not short-term

One of the most cited global studies in coffee climate science projects around a 50% reduction in climatically suitable area for coffee across scenarios by mid-century, with the heaviest impacts at lower altitudes and lower latitudes.

That is the core supply-security issue. Suitability is shifting upslope in many regions, but mountain land is finite. Over time, origins that were once stable can become more volatile in both quality and availability. For coffee buyers like our sourcing partners, this means treating origin diversity as risk management, not novelty.

At the roastery level, we treat this as portfolio planning. We do not rely on one country profile all year. We balance cups across origins and elevations so one bad weather cycle does not break consistency for customers. That includes keeping proven lower-acidity anchors like Brazilian Eagle alongside higher-altitude East African profiles.

3) From doom to strategy: what climate-resilient sourcing actually looks like

The industry is not standing still. The practical shift is from “climate concern” to climate engineering at the farm and variety level.

Resilient farm systems

Shade and agroforestry are not marketing buzzwords when they're done correctly. A 2024 meta-analysis found higher biodiversity in coffee farms with higher shade levels, while also warning that outcomes vary by region and design. Another global meta-analysis found stronger soil carbon outcomes in diversified coffee agroforestry systems.

For you as the consumer, the practical takeaway is that coffees from resilient farm systems are more likely to stay consistent over time because the farm itself is less fragile.

Resilient genetics (hybrids and future lines)

Varietal strategy now matters more than ever. Programs around lines like Marsellesa and Starmaya are designed around disease pressure and climate adaptation (World Coffee Research). We also keep an eye on frontier research such as Coffea stenophylla, which has shown Arabica-like sensory potential at significantly higher mean annual temperatures in early studies (Davis et al., Nature Plants).

We are not saying every new variety is automatically better. We are saying the future of quality coffee depends on genetic diversity, not a narrow dependence on legacy lines under rising climate stress.

4) The economic reality: why “cheap coffee” is often the highest long-term risk

If growers cannot earn enough to maintain farms, climate adaptation does not happen. The major rust-crisis analysis for Central America and Colombia found that severe epidemics repeatedly coincided with low profitability periods, where underinvestment made farms more vulnerable. The 2012 roya shock is still the clearest warning of what happens when climate stress and weak farm economics collide.

This is why we challenge the “lowest-price wins” mindset. The cheapest bag today can mean less farm reinvestment, weaker disease control, and lower future quality. That is not a sustainable value chain for anyone.

At the market level, weather shocks are already feeding through to price. FAO reported world coffee prices up 38.8% in 2024, driven largely by weather-related disruptions in key producing countries.

When people talk about the “C-market,” this is the benchmark they mean: ICE’s Coffee “C” contract, the global pricing reference for Arabica. If weather hits major producers, benchmark pricing can move quickly, and those moves eventually show up on retail shelves.

5) Sustainability is operational compliance now (EUDR and traceability)

This is not theoretical anymore. Forest-risk compliance is becoming an operational baseline. The European Commission’s implementation page sets EUDR application to 30 December 2026 for large and medium operators, and 30 June 2027 for micro and small operators.

Even outside the EU, this shifts expectations. Better geolocation, better due diligence records, and cleaner chain-of-custody data become normal practice across supply chains. Forest protection is also part of local climate stability in coffee landscapes, so this is both compliance and climate risk control.

Brewing tip: Keep your recipe stable before changing the dose. For cafetière, start at 1:15 (for example, 20g coffee to 300g water), adjust the grind one step at a time, and brew only what you will drink. Better consistency at home means less waste per cup.

Pressure point What it means for you Our response
Heat and faster maturation Potentially flatter flavour and less consistency Prioritise altitude and resilient origins (for example, African Moon)
Weather-driven supply shocks Unexpected price movement and stock gaps Diversified origin portfolio and forward planning, where possible
Disease pressure (including roya) Higher farm costs and quality volatility Preference for producers investing in agronomy, renovation, and resilient varietals
Compliance and traceability demands Harder to trust vague sourcing claims Lot-level sourcing detail and transparent product information

Buyer checklist: how to support climate resilience without overcomplicating it

  • Choose roasters that publish farm, region, altitude, and process details.
  • Support coffees from resilient high-altitude areas when available.
  • Be open to newer resilient varietals and changing origin rotations.
  • Expect periodic price adjustments as part of keeping farms viable.
  • Buy smaller, fresher quantities and brew consistently to reduce waste.

FAQ

Should I drink less coffee because of climate change?

No. The better move is to buy coffee that supports resilient production systems and transparent sourcing. Demand for responsibly sourced speciality coffee helps finance adaptation where it matters most.

Why are high-altitude coffees often part of a climate strategy?

Higher elevations usually provide cooler conditions that can protect maturation speed and cup complexity. It is not a guarantee, but it is an important risk-control lever as lowland pressure increases.

Does this mean all coffee prices will keep rising?

Not in a straight line, but volatility is likely to stay. Weather shocks, disease pressure, and compliance costs can all affect pricing. The key is buying from roasters who explain those shifts clearly rather than hiding them.

What is the most practical action I can take this month?

Pick one transparent roaster, buy a realistic bag size, and keep your brew method stable. You will waste less coffee and get better consistency from each bag.

Climate change is not just a sustainability headline. It is a quality, availability, and pricing reality already shaping your cup. Our job as a roastery is to adapt early, source responsibly, and keep your coffee reliable as conditions change.
