The coffee giant has developed six new varieties of Arabica beans that can better withstand some of the worsening effects of climate change – particularly, diseases such as coffee rust.

Starbucks announced today it is taking action in
the name of coffee lovers everywhere by creating six new, climate-resistant
coffee tree varietals — all of which produce Arabica, one of the two most
popular beans (along with Robusta), which are particularly vulnerable to
— and giving them away for free to farmers around the world. Developed over a
decade of research and testing by the Starbucks agronomy team, the company says
the new varietals are naturally resistant to diseases such as coffee leaf rust
and some impacts of climate change, while also delivering excellent taste and
The work is part of Starbucks' broader effort to deliver carbon-neutral green coffee by 2030.

The varietals were developed at Hacienda
Alsacia, Starbucks global research and
development facility and farm in Costa Rica, where the company’s agronomy
team’s primary focus is to better understand the challenges coffee farmers face
and promote sustainable models of farm management. Since 2005, Starbucks
agronomists have been advancing work on tree breeding to develop more productive
and more resilient coffee trees. To date, the team says it has researched,
developed and improved upon hundreds of hybrids and varietals.
“We put our efforts up against the development of climate-resistant trees,”
Starbucks’ EVP of global coffee, social impact and sustainability, told The Seattle Times.
“Very specifically, developing new tree varietals in a way that ensures that
they are more resistant to the impact of climate.”
According to World Coffee
climate change is the greatest long-term threat to the long-term sustainability
of coffee agriculture and to the preservation of the rich diversity of coffee
origins that exists today; impacts will vary by region. To develop the stronger
coffee strains — which are particularly resistant to coffee rust — the Starbucks
agronomy team planted and developed several varietals and hybrids and monitored
them for at least six generations, which takes about 12 years.
From the coffee trees or seedlings, the team sends leaf clippings for analysis
to a lab for early genetic clues about which trees are more resistant to common
diseases; then, they test to see how they process and absorb nutrients;
physically examine root systems and leaf structures; and taste early samples
from those producing coffee cherries. The team also evaluates the cup profile
(the coffee’s acidity, body and complexity) with Starbucks partners from
Colombia, Costa Rica, Seattle and Switzerland.
Once the team selects the varietals that are most naturally resistant to coffee
diseases and climate change, and have excellent taste and high productivity,
they are distributed through Starbucks’ seed program to suppliers and farmers;
to date, the company says more than three million seeds, including the six
varietals, have been distributed to coffee farmers in China, Costa Rica,
Guatemala, Honduras, Indonesia, Mexico, Nicaragua and
Peru — whether they sell to Starbucks or not.
Along with the potential rise of another climate-resistant bean called
Liberica being cultivated in
Starbucks’ new Arabica varieties could help safeguard the future of one of our
most beloved beverages.
