In the context of the contemporary coffee culture becoming increasingly refined, whether chain brands or independent coffee shops on street corners, many have joined the ranks of roasting their own beans, emphasizing full control over green bean selection, roast profiles, and final flavor. This article will introduce you to ten highly representative in-house roasting brands from around the world, including China, Germany, New Zealand, Japan, South Korea, Spain, Italy, Norway, Sweden, and the United Kingdom. Each has its unique roasting style and bean selection philosophy. Whether you prefer light roast fruitiness or dark roast richness, you can find a brand worth exploring.

The first stop is a well-known in-house roasting coffee shop in Guangzhou, China. Since its establishment in 2013, it has become a highly representative long-standing in-house roasting brand in the area. The brand not only operates official flagship stores on Tmall and Taobao, offering over 50 varieties of freshly roasted beans with diverse flavors online, but also updates daily through its official account, providing detailed introductions to each coffee bean’s origin, processing method, brewing suggestions, and flavor profile. It serves as a reference guide for many coffee beginners and advanced enthusiasts. The shop adheres to a minimalist store style, serving only coffee and a piece of handmade biscuit, allowing customers to focus on savoring the diverse expressions of the beans themselves—from fresh floral notes and layered fruit acidity to caramel sweetness. The offerings include pour over single origins, espresso blends, and a range from light to medium-dark roasts, suitable for consumers wanting to try different styles.

Next, we head to Europe,The Barn in Berlin, Germany Founded in 2010, it upholds the core philosophy of “paying attention to every step, from procurement to brewing.” Led by founder Ralf Ruller, it is practiced across its four coffee shops and roastery. The brand insists on sourcing directly from farms certified by the Cup of Excellence, prioritizing sustainably grown coffee beans, and employs what is called “slow roasting”—a technique leaning toward light to medium roasts—that allows the beans to showcase their most original regional flavor characteristics. It is an unmissable choice for enthusiasts who pursue detail and origin-specific qualities.

Coming fromCoffee Supreme in Wellington, New Zealand, established in 1993, it is considered one of the pioneer specialty coffee brands in the Southern Hemisphere. The brand has not only won numerous awards for packaging and store design but is also renowned for offering a diverse and high-quality selection of coffees. Its supply chain spans major specialty and secondary coffee producing regions worldwide, and it actively engages in sustainability efforts—for example, introducing the rare F1 hybrid espresso variety, which offers both high yield potential and low environmental impact, reflecting the brand’s vision and commitment to the future of the coffee industry.

Also exquisitely small yet highly capable isSwitch Coffee from Tokyo, Japan. Though run by just one owner, Masahiro Onishi, and a single Probat roaster, the technology and expertise behind it should not be underestimated. Onishi studied roasting techniques under Toshiyuki Ishiwata of Australia’s Market Lane Coffee and honed his green bean procurement skills under Katsuhide Izaki of Honey Coffee—the latter being a Cup of Excellence judge. This low-profile coffee roaster, with its precise roast flavors and high-quality beans, has earned personal certification from celebrity chef René Redzepi. Even among Japan’s many renowned roasters, it maintains a uniquely distinctive style.

In180 Coffee in Seoul, South Korea , established in 2013, it quickly rose to become one of the country’s top roasting companies. Facing a market environment previously dominated by instant coffee, South Korea has seen rapid development in the specialty coffee sector in recent years, with the number of coffee shops tripling in just five years. 180 Coffee is not only one of the very few brands in the country to hold two coffee roasting titles, but its roasting standards have also gained recognition on the global stage, making it a name worth watching for Asian specialty coffee enthusiasts.

Next, we visitRight Side Coffee in Castelldefels, Spain, a roastery founded by Joaquin Parra, the champion of the Spanish Coffee Roasting Championship, and driven by the brand spirit of “creativity and passion.” His father is a green coffee importer, and Joaquin himself is a frequent participant in the World Coffee Roasting Championship. The brand’s hallmark is that each bag of coffee beans comes with a detailed farm information label, clearly recording the origin background, processing method, and historical story, enhancing consumers’ understanding of the beans’ sources. Although it does not have its own storefront, it has stable distribution channels across Spain, making it an excellent choice for finding coffee beans with a story.

In Forlì, Italy,Gardelli Specialty Coffees, founded by Rubens Gardelli, a legendary figure in the roasting world who has won multiple World and Italian Roasting Championships, adheres to light roasting to prioritize respecting the beans’ innate characteristics rather than letting the roasting style dominate the final outcome. The brand’s online store regularly updates its product offerings, which even include extremely rare Ethiopian Gesha Village coffees—and Gardelli is the only roaster in Europe able to provide this particular bean. For players seeking ultimate flavor, it is an uncommon and exceptional choice.

In the Nordic region,Solberg & Hansen in Oslo, Norway , founded in 1879, is the country’s oldest coffee roasting company, with a history of over 130 years. Led by Simo Christidi, who was ranked in the top five at the 2012 World Coffee Roasting Championship, its concept store at the Mathallen food market focuses on a pure coffee experience—without milk or sweeteners—allowing customers to focus on the essence of the coffee itself.

Also from the Nordic region,Drop Coffee in Stockholm, Sweden , established in 2009, initially started as a small coffee shop that did not roast its own beans, but later became a significant contributor to the third wave coffee movement in Europe. The team’s roaster, Joanna Alm, has won the title of Sweden’s Best Roaster multiple times, and the brand has performed outstandingly in international competitions, second only to Gardelli. Though its physical store is small, its website is designed to feel warm and personal, like a family photo album, conveying the brand’s charm of combining warmth with professionalism.

Finally, we arrive atSquare Mile Coffee Roasters in London, UK, co-founded by Anette Moldvaer and James Hoffmann, with the goal of making London an important city on the world coffee map. The brand strictly practices sustainable sourcing and is known for discovering specialty beans from potential-producing regions—for example, it has launched rare coffees from China and Myanmar, origins that are extremely uncommon in the global market. Its product line is updated regularly, and online purchasing is convenient, making it an ideal choice for enthusiasts seeking fresh and unique-flavored beans.
