In response to the Worldwide Espresso Organisation, Indonesia is the world’s fourth-largest producer of espresso. In 2020, the country produced around 12.1 million 60kg bags of coffee – a rise of 5.8% on the earlier yr.

The overwhelming majority of espresso grown in Indonesia is robusta. The USA Division of Agriculture (USDA) estimates that the country will produce some 9.3 million 60kg bags of robusta through the 2021/22 harvest season.

Regardless of the big volumes of robusta that Indonesia produces, most of it’s utilized in blends or in soluble espresso merchandise. The primary purpose for that is the notion that robusta is of decrease high quality than arabica – largely on account of minimal high quality management for robusta manufacturing.

However is there an opportunity this might change? To be taught extra, I spoke with a number of native espresso professionals. Learn on for his or her perception into Indonesian robusta.

An outline of robusta manufacturing in Indonesia

Robusta is a serious money crop for Indonesia. In reality, in keeping with Index Mundi, Indonesia is the world’s third-largest robusta producer after Brazil and Vietnam. So why does the nation develop a lot robusta?

Mia Lakhsmi Handayani is a R grader (also referred to as a Q robusta grader) in Indonesia.

“The nation’s huge areas of appropriate land for espresso manufacturing, in addition to its completely different microclimates, make it supreme for producing robusta espresso,” she says. 

She provides: “These situations additionally imply robusta flavours can vary from extra delicate, delicate coffees with notes of chocolate and fruit grown in Central Java, to extra intense flavours of vanilla and chocolate, like robusta grown in Sumatra.” 

The biggest robusta-producing areas in Indonesia are primarily present in southern Sumatra – an island situated west of Java. Sumatra’s excessive temperatures make it extra supreme for rising robusta than arabica.

Like in lots of producing nations, the majority of farmers in Indonesia are smallholders who grow coffee on around one or two hectares of land. As many smallholder farmers produce espresso on a subsistence stage, they typically retain little cash to reinvest into their farms, which understandably means high quality management can develop into a difficulty.

Why do we have to enhance robusta high quality?

Denny Hermawan can be a R grader in Indonesia. He explains a number of the points which robusta farmers face within the nation.

“Robusta manufacturing in Indonesia is plentiful, however high quality and yields have to be improved,” he says.

Along with an absence of widespread high quality management measures, there are additionally issues round differentiating between fine robusta and commodity-grade robusta. To be thought of high-quality robusta by the Fine Robusta Standards and Protocols, a 350g pattern of inexperienced espresso shouldn’t have any major defects and not more than 5 secondary defects.

With high quality management persevering with to be a difficulty in Indonesian robusta manufacturing, it may be troublesome firstly for smallholder farmers to establish the standard of their robusta, after which subsequently to enhance it in the event that they want to take action.

Moreover, if producers are already producing high-quality robusta however do not need the data or tools to confirm this, they might doubtlessly be lacking out on alternatives to scale their earnings.

Nevertheless, these should not the one points that Indonesian robusta manufacturing faces.

In response to the paper Effects of Climate Change on Global Coffee (Coffea arabica L) Production, world warming might have devastating results on the nation’s arabica-growing land. 

Within the examine, the researchers declare that as a result of as much as 37% of the nation’s land could develop into unsuitable for arabica manufacturing, Indonesian farmers could must “climb increased” to succeed in higher rising situations.

Nevertheless, it might additionally imply that Indonesian arabica farmers in the end could also be compelled to provide extra robusta, as it’s rather more climate-resilient than most arabica varieties. This might have detrimental results on their earnings – largely as a result of farmers obtain increased costs for arabica in comparison with robusta.

In flip, this implies an growing give attention to enhancing robusta yields and high quality is changing into increasingly important for the way forward for Indonesia’s espresso trade.

Challenges in Indonesian robusta manufacturing

Alongside the growing menace of local weather change, Indonesia’s robusta farmers face a spread of different difficulties

In response to the Indonesian Ministry of Agriculture, most espresso farms within the nation yield about 817kg of cherry per ha. Nevertheless, robusta vegetation are able to yielding as a lot as 1,300kg per ha – indicating a productiveness hole. In essence, because of this extra funding could possibly be wanted to make robusta vegetation extra productive.

“Most farmers solely personal small plots of land for robusta manufacturing, [and with such low prices for robusta], they’re struggling economically,” Mia explains. “Their financial state of affairs is made worse by the truth that the robusta vegetation have to be pruned and fertilised, which prices cash.”

On account of ongoing preconceptions about robusta as being of decrease high quality than arabica, many farmers in Indonesia make investments much less in processing and post-harvest for his or her robusta vegetation.

“Some producers don’t see the total potential of robusta as a result of they obtain much less cash for it than arabica, in order that they focus extra on amount over high quality,” Denny says. 

Riswan Fitriyandi is a robusta farmer in Indonesia. He agrees {that a} lack of high quality management throughout robusta manufacturing is an issue in Indonesia.

“There’s a lack of sustaining high quality management,” he tells me. “Throughout harvest, pickers will take away all the cherries, no matter whether or not they’re ripe or not, which may have an effect on the harvest the next yr.

“It’s not straightforward to vary these practices as they’ve develop into considerably regular in Indonesian robusta manufacturing,” he provides.

Finally, the difficulty circles again to data and useful resource availability so far as the proper manufacturing and processing strategies for robusta are involved. Moreover, with farmers accustomed to decrease costs, in addition to worldwide perceptions of robusta being decrease in high quality, market progress definitely seems to be like a problem at current.

Enhancing high quality management requirements

So, how can the standard of Indonesian robusta be improved?

Denny believes that it begins with growing farmers’ entry to training, together with assets for processing espresso. That is particularly necessary because it’s estimated that post-harvest can be responsible for up to 60% of overall coffee quality.

“It permits farmers to type higher-quality robusta beans from commercial-grade beans,” he says. “I develop about 200 robusta vegetation and attempt to share my data and knowledge on find out how to conduct correct processing strategies with different farmers. 

“My strategies is probably not relevant to all farms in Indonesia, however they at the very least present normal steerage on find out how to enhance robusta high quality,” he provides.

Mia agrees, saying that extra folks in Indonesia have to be made conscious of the existence of high-quality robusta. 

“When extra individuals are conscious of specialty-grade arabica, the marketplace for it grows, which implies connections to farmers are a lot simpler to return by,” she tells me. “That’s why I grew to become a R grader within the hope that it’s going to enhance consciousness and demand of high-quality robusta, and in the end enhance the standard of robusta in Indonesia.”

She tells me how high-quality robusta can generally have related flavour profiles to arabica. 

“I first tried a high-quality robusta in 2005,” she says. “It had a citrus-like acidity and a very good physique – it will have been scrumptious as a single origin espresso.”

Provided that the C worth for arabica has been steadily growing for over the previous yr, roasters’ shrinking profit margins could imply they give the impression of being to extra reasonably priced sourcing choices to proceed to fulfill calls for for fascinating cup profiles.

“The potential for robusta is certainly there; we simply need to discover a manner to make use of our expertise and data to deliver the very best out of it,” Denny says. “By rising higher-quality high-quality robusta, we will create a extra viable marketplace for Indonesian farmers.”

Riswan agrees, saying: “The outcomes of the first-ever Cup of Excellence Indonesia had been promising final yr, and I consider robusta also can shine in the identical manner [given the right time and investment].”

There’s little doubt that making use of stricter high quality management requirements throughout the Indonesian provide chain will end in higher-quality robusta. However to keep up these enhancements, these requirements have to be scalable and accessible.

A big a part of this revolves round growing entry to farmer training – which implies supporting producers to be taught extra about robusta manufacturing and the way high quality management could be improved. If we accomplish that, then Indonesia might enhance its status inside the area of interest of high-quality robusta espresso.
