Soaring coffee prices

February 20, 2025 By EarthWise Leave a Comment

Coffee prices are soaring again

Wholesale coffee prices hit record highs in the midst of the Trump administration’s deportation and tariff dispute with Colombia.  But coffee prices have already been trading near 50-year highs for a while as a result of shortages related to extreme weather and increased global demand.

In recent years, repeated droughts and flooding have put pressure on the global supply of coffee.  These climate swings have caused prices to soar, much as they have for other staples like cocoa, olive oil, and orange juice.  All the while, the global demand for coffee has kept rising.

Coffee is one of the world’s most consumed beverages, but it can be grown only under very specific conditions, namely in misty, humid, and tropical climates, and in rich soil free of disease.   The United States imports nearly all of its coffee – there is only a small amount grown in Hawaii.  Otherwise, the US is the world’s largest coffee importer.  With a limited number of sources for the beans, global coffee prices are very susceptible to the effects of extreme weather.

More than half of the world’s coffee production comes from arabica beans, and Brazil is the largest exporter.  A severe drought there this summer devastated the harvest that typically runs from May to September.   In Vietnam, a severe drought followed by heavy rains harmed the world’s largest source of robusta, the second most popular coffee variety.

People tend to think of coffee as a commodity and not so much as an agricultural product, subject to the vagaries of weather and having prices that fluctuate accordingly.  The bottom line is that drinking coffee is likely to become a bigger strain on one’s own bottom line.

Climate-smart coffee

Growing climate-smart coffee

Do you crave that morning cup of coffee?  You’re not alone, and not by a long shot.  In fact, more than 2.2 billion cups of coffee are consumed globally every day. 

The existing coffee market is dominated by two species: Coffea arabica and Coffea canephora (the latter commonly called robusta).  Historically, coffee drinkers have preferred Arabica beans for their specific flavor and aroma. 

But climate change is threatening many crops around the world, and maybe none more so than coffee.  In fact, an alarming 50% of suitable coffee-growing land is projected to be lost by 2050.  As a result, scientists see two alternatives to supplement Arabica: either adapt coffee farming practices to new environments, or focus on coffee species that are more resilient.

According to a new study led by researchers from the University of Florida, Robusta coffee might be a good candidate to augment Arabica.   The researchers evaluated Robusta and Arabica for multiple traits in three high-altitude locations in Brazil over five years.

The study, which was recently published in the journal Crop Science, found that Robusta is highly adaptable and grows in high-altitude regions, which means it combines good production and flavor scores.  According to the researchers, Robusta can combine the following three elements for coffee cultivars: Sustainability (produce more with fewer inputs), quality (good flavor to meet consumer demand), and plasticity (capacity to adapt to new production systems).

Following these favorable findings with Robusta in Brazil, the scientists will test whether the species can grow in Florida.

How to save coffee from climate change

The global coffee market is valued at over $450 billion a year and supports the economies of several tropical countries.  About 100 million farmers depend upon coffee for their livelihoods. 

Coffee bushes grow best in a narrow range of temperatures.  The existing coffee market is dominated by two species Coffea arabica and Coffea canephora, the latter commonly called robusta.  Arabica, the most preferred coffee, thrives in average temperatures between 64 and 72 degrees Fahrenheit.  Robusta does not flourish above 75 degrees.  Therefore, the warming climate is making growing coffee increasingly difficult.

There are actually well over 100 species of coffee.  Many of them grow in warmer places than those preferred by robusta and arabica, but are considered to have poorer flavors, smaller beans, and lower yields.

Researchers at the Royal Botanic Gardens in Britain came across a paper written in 1834 about a species of coffee from the lowland hills of Sierra Leone called Coffea stenophylla.  According to the paper, stenophylla supposedly has a flavor superior to arabica’s. 

It turns out that stenophylla still grows in parts of Africa with temperature ranges between 75 and 80 degrees.  It was actually farmed until the 1920s but was abandoned because robusta was found to have higher yields.

Extensive taste testing verified the positive attributes of stenophylla.  Whether it should be cultivated directly tolerating potential yield issues or crossbred with existing commercial coffees remains to be determined.  But the prospects for finding more heat tolerant coffees should be encouraging news for coffee addicts.

Is Coffee Endangered?

There are many worries related to climate change, notably the increasing occurrence of extreme weather events, melting polar ice, rising seas, and so forth.  But perhaps one of the most ominous warnings comes from a new report issued by the Climate Institute about the future of coffee.
