Born from Suntory's century-long dedication to beverage craftsmanship, this concentrate was created for the modern coffee lover who values both flavor and wellness. In Japan's fast-paced lifestyle, the demand for a premium, instant coffee without the sugar crash led our R&D team to develop a proprietary extraction method. We selected only high-grade Arabica beans and applied a patented low-heat technique to lock in the deep, smooth notes typically lost in sugar-free products. Every batch is produced in our GMP-certified Japanese facilities, adhering to the strict FOSHU (Food for Specified Health Uses) standards for quality assurance. This commitment has made it a top-ranked, trusted choice in the ready-to-drink coffee category for discerning Japanese consumers.

Suntory Boss Cafe Base Sugar-Free Coffee Concentrate - 340ml is formulated with a carefully selected blend of ingredients designed to deliver a rich coffee experience without added sugars. The primary ingredient is coffee extract, which provides the robust flavor and aroma characteristic of high-quality coffee, sourced to ensure a consistent and satisfying taste profile. Water is included as a solvent to create the concentrated liquid form, allowing for easy dilution and customization according to personal preference. To achieve its sugar-free designation, the product utilizes artificial sweeteners such as acesulfame potassium and sucralose, which mimic the sweetness of sugar without contributing calories or affecting blood sugar levels, making it suitable for those managing dietary restrictions or weight goals. Additionally, it contains acidity regulators like sodium citrate and potassium phosphate, which help stabilize the pH balance, enhancing flavor consistency and shelf life by preventing spoilage. Preservatives such as potassium sorbate may be included to maintain freshness and prevent microbial growth, ensuring the product remains safe for consumption over time. This combination of ingredients offers users a convenient, low-calorie coffee option that retains the depth of traditional coffee while supporting health-conscious lifestyles through reduced sugar intake and extended usability.
