How we roast coffee
Throughout its short history, JAVA Coffee Roasters has never roasted robusta beans and never will. In our roastery, we use only the finest varieties of arabica beans — this is one of the principles we adhere to when roasting coffee. We approach every process with passion and dedication, ensuring the beans reward us with exceptional flavor and aroma.
How and on What Equipment Does JAVA Coffee Roasters Roast Coffee?
Roasting coffee is not just an art; it is, above all, a science. Modern roasting requires cutting-edge construction and technological solutions in the roastery, as well as extensive knowledge and dedication from roasters. This enables us to bring out the full flavor and aroma of every single coffee bean. A kilogram of microlot coffee (high-quality coffee harvested from a small farm area) can cost up to $100 USD, so we must ensure that our knowledge and equipment are sufficient to unleash the potential within the beans.
Every mistake in processing the beans is a missed opportunity to delight, leading to unsatisfactory taste and a dissatisfied customer whose expectations were not met. Despite being in operation for 22 years, JAVA Coffee Roasters' craftsmanship is not defined by history but by every batch of coffee roasted. That’s why we stay up to date with the latest “know-how” in coffee roasting and continuously modernize our roastery.
JAVA Coffee Roasters specializes in light and medium coffee roasting within the Specialty and Fine Coffee markets. The difference between these roast levels comes down to seconds, making control and precision paramount.
In 2013, we introduced the Loring Kestrel S35 roaster to our facility, followed by the Diedrich CR-25 in 2018. Both machines were imported from the United States and crafted by the best specialists in the industry.

The Loring is a roaster perfectly suited for urban environments, as it is an energy-efficient machine that reduces carbon dioxide emissions during roasting by up to 80%. The Loring is made entirely of steel and comes equipped with integrated electronics. We service the machine annually to maintain it in top condition, in line with technological advances. The precision of the Loring’s electronics allows us to maintain full control over every roast.
The Diedrich CR-25 is a popular choice for specialty roasters. Its drum is constructed from heat-conductive materials (steel-copper-steel), enabling us to precisely control every roast and avoid defects that might arise during the process.
For roasting coffee on both the Loring and Diedrich machines, we use Cropster software. Currently, Cropster is the industry standard, as it allows full control of the coffee from the moment it is contracted to when it reaches our customers’ cups. With Cropster, we can save all the profiles we create, enabling comparisons and analyses with the latest harvests. This approach allows us to classify and control the beans we roast. Thanks to Cropster, every roast has the potential to hit the mark — and it does!
Providing our customers with the best coffee is our priority. In a single month, we may sample 50 or more (who’s counting...) types of beans to achieve this goal. We roast the samples we receive from our suppliers on the IKAWA roaster. This is a labor-intensive task, as hunting for quality green beans and selecting the optimal roast profile to bring out the best in the coffee is a long and demanding process.
How Do We Source Our Coffee?
The coffee we choose for our offerings is a high-quality, carefully selected raw product subjected to rigorous quality testing.
The plantations we source our beans from belong to the best farmers who put great effort into ensuring their beans retain their natural flavor and character after processing. We work with producers who operate sustainably and employ eco-friendly production methods. Our offerings include beans from all over the world — not only from well-known coffee regions like Brazil and Colombia but also from Ethiopia, Kenya, Guatemala, and more exclusive origins like China, Honduras, Myanmar, Papua New Guinea, and beyond.
An essential part of our work is ensuring the quality of the roasted beans.
Every batch we roast is coded and tested through cupping, allowing us to objectively determine whether the coffee is defect-free and ready for sale.
