Although it is the worldโ€™s second-largest coffee producer, Vietnam has never had a reputation for producing high-quality Arabica. Robusta accounts for the majority of beans grown in the country, meaning that the likeliest place youโ€™ve experienced Vietnamese coffee is in espresso blendsโ€”where it’s added for crema-improving qualitiesโ€”or as instant, freeze-dried powder.

This year, three domestic producers are hoping to change that. Tran Nhat Quang fromย La Viet Coffee, Nguyen Dung fromย The Workshop, and Nguyen Canh Hung fromย Bosgaurus Coffee share a mutual vision of bringing Vietnamese Arabicaโ€™s overall quality up to specialty standards. By innovating growing and processing practices in Vietnam’s central highlands, they hope to develop a high-quality coffee production model that can scale.ย

The three chose to hone in on a single varietal for improvementโ€”Catimor. Catimor, often typecast by the specialty coffee industry for its characteristics inherited from Robusta, is nonetheless widely planted in Vietnam due to its high yield and leaf rust resistance. Its quality improvement could, as a result, have a major impact on the countryโ€™s overall coffee quality, and affect a greater number of producers than that of any other varietal.ย 

The First Brick In The Wall

Broad changes to industry take time and effort. This year, the three producers focused on improving the cup quality from a single farmโ€”owned and operated by Pham Manh Hung. They helped Pham implement harvesting and processing best practices across his five-hectare land area (about the size of seven soccer fields), which has a production capacity of 10 tons of Catimor per year.

Phamโ€™s farm is located at 1,450 meters above sea level, in the Lam Dong regionโ€™s Cau Dat areaโ€”Lam Dong is where the majority of Arabica is cultivated in Vietnam, with varietals overwhelmingly constituted of Red and Yellow Catimor. Prior to this year, Pham had been planting commodity-grade coffee for 10 years. He decided to collaborate with La Viet, The Workshop, and Bosgaurus to raise his coffee quality to specialty standards.ย 

They began with the harvest.

Because strip harvesting is the norm in Vietnam, it is vital to provide producers with skills in selective picking. Wages for harvesting are typically paid by weight of picked cherryโ€”to increase quality, that metric has to be shifted to cherry quality.

โ€œOld habits die hard,โ€ Bosgaurus Coffee owner Nguyen Canh Hung says of the implementation of quality-focused picking on Pham’s farm. โ€œAlthough we paid pickers higher wages than the market standard, close monitoring and incentives to reward pickers were needed to improve quality. We gradually increased the percentage of ripe cherries picked, achieving 99% by the end of the harvest.โ€

Trust The Processing

Bosgaurus Coffee

For the owners of Bosgaurus, La Viet, and The Workshop, acquiring ripe cherries was just the first step in a longer journey to scale specialty grade coffee in Vietnam. The next step was applying innovative processing methods. Generally, processing is overlooked by the countryโ€™s coffee industry, and in fact is regarded as a potential risk to quality rather than a tool with which to improve it. The industryโ€™s assumption as a whole is that the longer a coffee’s processing time, the higher the risk of beans being subject to unexpected weather changes. Bosgaurusโ€™ Nguyen believes that changing this mindset is crucial, and that processing could become a positive agent of increasing quality if he can reduce its variability.

The three producers started by experimenting with a processing method borrowed from wine production called yeast fermentation. They bought yeasts fromย Fermentisโ€”a company specializing in producing yeasts for beer and wine processing. Yeasts were hydrated and injected into fermentation tanks along with coffee seeds for different durations, between 22 and 72 hours. Every two hours during the fermentation process, data on moisture content, humidity, temperature, water quality, pH, and degrees Brix were measured and recorded.

After, washed beans were dried on raised beds for 20 days. Typically, Vietnamese Catimor tends to have a sharp acidity, with a woody and nutty flavor. Coffee from one recent batch of 72-hour yeast-processed Catimor prepared with a Hario V60, however, dazzled with a bright and fruity acidity more akin to Kenyan coffeesโ€”the mouthfeel was juicy and the aftertaste sweet. And although this particular brew had some of the varietal’s signature woody flavor, once cooled, the cupโ€™s overall complexity was remarkable.

โ€œFor now, the exact effect of yeasts on coffee flavor remains to be seen,โ€ Bosgaurusโ€™ Nguyen says. โ€œAs this is a novel approach to coffee processing, we cannot say for sure which yeast strain will contribute which flavor to the coffee.โ€

He went on to explain that through a relationship with Lucia Solis, a prominent coffee fermentation designer currently experimenting with yeast fermentation processing in countries across South America, he was developing specific processing techniques to bring sweetness to Catimorโ€™s flavor profile. Theyโ€™re also finding that longer fermentation times appear to lend more complexity and higher cupping scores to coffees.

The quality specialists in Vietnam are also experimenting with a method of juice fermentation, which entails flushing fermentation tanks with water, yeast, and fresh, concentrated pineapple juice for a period of 36 hours. The juice provides nutrition for the yeasts, accelerating their microbial activity to add fruitier flavors to coffee. The end result of one juice fermentation trial was a sample aptly named โ€œPineapple,โ€ whose cups had an aroma of tropical fruit, a citrus-like acidity, a hint of orange sweetness, tea-like body, and a chocolatey finish.

Along with the batches of yeast and juice-fermented coffees, a sample of anaerobic, naturally fermented Catimor was recently served at Bosgaurus in limited quantity. Nguyen says the goal for developing this particular method is to promote cup consistency.

Looking Forward

Measuring the experiments on Phamโ€™s farm in terms of their impact on cupping scores is already taking place.

โ€œWe sent samples toย Johan & Nystrรถmย in Sweden,ย Tobyโ€™s Estateย in Australia, and partners in Germany and Japan for blind cuppings,โ€ Nguyen says. โ€œIn the United States, with the help ofย Modbar‘s Will Frith, our coffee was cupped atย Sustainable Harvest.”

The results of these blind cuppings were striking. All samples received cupping scores between 82 and 84. As details about each coffee were revealed, those who had taken part in the exercise were surprised.ย ย 

โ€œThe change we achieved this year was promising,โ€ Nguyen says. โ€œWe owe this success to the hard work of farmers and baristas from La Viet, The Workshop, and Bosgaurus. Next year, we want to keep up the good work and establish a stable production model, before replicating it on other farms in the region.โ€

For now, new facilities, equipment, and plans are already being prepared for Phamโ€™s next crop.
