鹿児島黒酢 (Kagoshima Kurozu)

Fukuyama Kurozu is one of Japan's MAFF-registered GI products; outdoor clay-pot fermentation method has 200+ year heritage; recognised under EU-Japan EPA.
Acetic acid 4-6%; total amino acid 200-400 mg/100ml (3-5x industrial rice vinegar); polyphenol elevated by long aging.
Premium drinking-vinegar retail, Kurozu-positioning supplements, traditional-craft hospitality export.
Brown-pot fermented unpolished-rice vinegar produced exclusively in Fukuyama, Kagoshima. The 200+ year-old kame-tsubo (clay-pot) outdoor fermentation method — sun-warmed, naturally aerobic, multi-year aging — yields amber-brown vinegar with significantly higher amino-acid content than industrial rice vinegar. The 'Fukuyama Kurozu' label is GI-protected with rigorous geographic and method definitions. Sakamoto Brewing (1812) and Fukuyama Black Vinegar Cooperative producers anchor the supply. Used in premium beverage, traditional Chinese-medicine-adjacent supplements (FFC notifications exist), and increasingly cosmetic AHA-positioning skincare.
