Source details
Brewed coffee and tea are not significant dietary purine sources. The USDA & ODS-NIH Database for the Purine Content of Foods (Release 2.0, March 2025) catalogs 462 foods and 15 alcoholic beverages but lists no brewed coffee or black tea; its only brewed tea (green tea beverage) is 1.67 mg/100 mL. The methylxanthines in coffee/tea (caffeine, theobromine) are NOT the uricogenic purine bases (adenine, guanine, hypoxanthine, xanthine) that the database measures. Coffee intake is associated with LOWER serum urate and reduced gout risk (Choi HK, Curhan G. Arthritis Rheum. 2007;57(5):816-821; Choi HK, Willett W, Curhan G. Arthritis Rheum. 2007;56(6):2049-2055). Total purine therefore set to 0 mg/100 g (negligible).

Values are per 100g unless a note says otherwise, rounded to three significant figures; per-serving figures are calculated from the unrounded measurement, so recomputing from the rounded number can differ by a milligram or so. A single determination is normal in food composition tables, not a defect. Last reviewed July 18, 2026.
