Stenophylla was found to have a complex flavour profile, with natural sweetness, medium-high acidity, fruitiness and good “body” — the way it feels in the mouth

In dense tropical forests in Sierra Leone, scientists have rediscovered a coffee species not seen in the wild in decades — a plant they say may help secure the future of this valuable commodity that has been imperiled by climate change.

The researchers said on Monday that the species, called Coffea stenophylla, possesses greater tolerance for higher temperatures than the Arabica coffee that makes up 56% of global production and the robusta coffee that makes up 43%. The stenophylla coffee, they added, was demonstrated to have a superior flavour, similar to Arabica.

Botanist Aaron Davis, who led the study published in the journal  Nature Plants, said stenophylla was farmed in parts of West Africa and exported to Europe until the early 20th century before being abandoned as a crop after robusta’s introduction.

Many farmers throughout the world’s coffee-growing belt already are experiencing climate change’s negative effects, an acute concern for the multibillion dollar industry.

Arabica’s flavour is rated as superior and brings higher prices than robusta, which is mainly used for instant coffee and coffee blends. But Arabica has limited resilience to climate change and research has shown its global production could fall by at least 50% by mid-century.

Stenophylla grows at a mean annual temperature of 24.9℃ — 1.9℃ higher than robusta coffee and up to 6.8°C higher than Arabica coffee, the researchers said.

The stenophylla rediscovery, Davis said, may help in the “future-proofing” of a coffee industry that supports the economy of several tropical countries and provides livelihoods for more than 100 million farmers. While 124 coffee species are known, Arabica and robusta comprise 99% of consumption.

“The idea is that stenophylla could be used, with minimum domestication, as a high-value coffee for farmers in warmer climates,” said Davis, head of coffee research at Britain’s Royal Botanic Gardens, Kew.

“For the longer term, stenophylla provides us with an important resource for breeding a new generation of climate-resilient coffee crop plants, given that it possesses a great flavour and heat tolerance. If the historic reports of resistance to coffee leaf rust and drought tolerance are found to be correct, this would represent further useful assets for coffee plant breeding,” Davis added.

Leaf rust is a fungal disease that has devastated coffee crops in Central and South America.

The study included flavour assessments involving 18 coffee-tasting experts. Stenophylla was found to have a complex flavour profile, with natural sweetness, medium-high acidity, fruitiness and good “body” — the way it feels in the mouth.

In December 2018, Davis and study co-authors Jeremy Haggar of the University of Greenwich and coffee development specialist Daniel Sarmu searched for stenophylla in the wild. They initially spotted a single plant in central Sierra Leone. About 140 km away in southeastern Sierra Leone, they found a healthy wild stenophylla population.

“Both locations were thick tropical forest, but stenophylla tends to occur on drier, more open areas: ridges, slopes and rocky areas,” Davis said.

Stenophylla had not been seen in the wild in Sierra Leone since 1954 and anywhere since the 1980s in Ivory Coast, Davis said. A few examples were held in coffee research collections.

Davis said stenophylla is threatened with extinction amid large-scale deforestation in the three countries where it has been known to grow in the wild: Sierra Leone, Guinea and Ivory Coast.

Unlike the red and occasionally yellow fruit of Arabica and robusta plants, stenophylla’s fruit are intense black. The coffee beans are inside the fruit.

“I think we’re hugely optimistic for the future that stenophylla can bring,” said Jeremy Torz, co-founder of the specialty coffee business Union Hand-Roasted Coffee in East London where part of the taste-testing was held.

• Emirati Coffee reported a 3,135 percent increase in online sales in 2020, fueled by strong market demand for its specialty coffee produce

Jeddah : 

Emirati Coffee, the UAE’s first specialty coffee roastery, is expanding into the Kingdom with the opening of its first Saudi branch in July 2021. The chain, which currently has 160 locations worldwide, will open in Alkhobar under the brand name Knowhere.

The company is preparing to open an outlet in Riyadh in 2022.

Mohamed Ali Al-Madfai, CEO of Emirati Coffee, told Arab News that the Riyadh outlet would be called the Emirati Coffee Roastery.

Al-Madfai said he believed there was great potential for growth in the Saudi market and that he is aiming to capitalize on the brand’s popularity among Saudi travelers, “especially those that came to love that brand when visiting Dubai pre-pandemic,” he said. Emirati Coffee reported a 3,135 percent increase in online sales in 2020, fueled by strong market demand for its specialty coffee produce.

The busiest period was during the first two months of the pandemic, when the UAE launched a national sterilization campaign to contain the virus. “Coffee was already the number one e-commerce grocery product before 2020, but the pandemic boosted the growth due to greater consumption at home.

Coffee buyers cut back on trips to the supermarket and coffee drinkers can’t go to the cafés,” Al-Madfai said.

He added: “Consumers resorted to online purchases and with the availability of our own delivery fleet, they were able to get their hands on their cup of coffee.”

New York :

 Coffee pulp, a waste product of coffee production, could be used to speed up tropical forest recovery on post agricultural land, suggests a new study.

In the study published in the journal ‘Ecological Solutions and Evidence’, the team spread 30 dump truck loads of coffee pulp on a 35-40m area of degraded land and marked out a similar sized area without coffee pulp as a control.

“The results were dramatic”, said lead researcher Rebecca Cole from the University of Hawai’i in the US.

“The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses,” Cole added.

After only two years, the coffee pulp treated area had 80 per cent canopy cover compared to 20 per cent in the control area. The canopy in the coffee pulp area was also four times taller than that of the control area.

The addition of the half metre thick layer of coffee pulp eliminated the invasive pasture grasses which dominated the land.

These grasses are often a barrier to forest succession and their removal allowed native and pioneer tree species, that arrived as seeds through wind and animal dispersal, to recolonise the area quickly.

The researchers also found that after two years, nutrients, including carbon, nitrogen and phosphorous, were significantly elevated in the coffee pulp treated area compared to the control.

For the study, the researchers analysed soil samples for nutrients immediately prior to the application of the coffee pulp and again two years later.

They also recorded the species present, the size of woody stems, percentage of forest ground cover and used drones to record canopy cover.
