Metode penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan tiga taraf perlakuan (ekstrak bayam merah : ekstrak jahe : gula aren) yaitu (70% : 15% : 15%), (80% : 10%10%) dan (85% : 7,5% : 7,5%). Analisis produk yang dilakukan meliputi uji organoleptik (uji hedonik), nilai pH, total padatan terlarut (TPT) untuk menentukan produk terpilih. Analisis terhadap produk minuman ekstrak bayam merah terpilih yaitu uji zat besi dan antioksidan. Analisis data yang digunakan yaitu ANOVA dan uji lanjut Duncan. Minuman ekstrak bayam merah terpilih adalah (ekstrak bayam merah 70%, ekstrak jahe 15% dan gula aren 15%), yang memiliki nilai pH 7,2, total padatan terlarut 15,5 °Brix, dan zat besi 0,39 mg/100 g dan antioksidan dengan nilai 7,58 mg/mL (7580 ppm).
