Alchemist The Heeren

About Alchemist The Heeren

Alchemist is a Singapore specialty coffee roaster celebrating 10 years of business, built around a simple belief that quality coffee is made with clarity and consistency. The company started as a small coffee bar at International Plaza, built by baristas, and has grown into a brand with multiple store locations, including an Arab Street pop-up, while now offering international shipping to selected countries.

Alchemist's range includes single-origin coffees from Uganda, Colombia, Bolivia, El Salvador, Ecuador and Honduras, alongside its three Signature Blends - Dark Matter (bold, velvety, with roasted nuts and chocolate), Lumos (bright and juicy, with fruit and floral notes), and Equilibrium (balanced and smooth, with dried stonefruit and hazelnut notes). These are available as whole beans, drip bags, capsules, and soluble formats for those without brewing equipment. For its 10th anniversary, Alchemist released a limited-quantity Coffee Set handpicked by its Director of Coffee, featuring three coffees that trace how the brand's understanding of coffee has evolved over the decade.

Beyond retail, Alchemist runs hands-on workshops - a Barista Brewing Workshop covering tasting, calibration and brewing fundamentals, and a 10th Anniversary Coffee Showcase built around its anniversary coffee selection - both led by senior members of the Alchemist team and capped at small group sizes. The anniversary is also marked with a 10-chapter brand story and a limited-edition Miniature Keychain Series, with the full collectible set available exclusively at the Arab Street pop-up store.
