Raised on yeast-fermented feed — a rare Shinshu brand pork of fine-fibered, juicy meat.
Kurenai Suiton is a Japanese brand pork (meigara-buta) from Nakano City, Nagano Prefecture, managed by Shinshu e-Loop Business Cooperative. Breed / crossbreeding: Two-breed cross (hybrid): Landrace × Large White.
Kurenai Suiton, nurtured in the rich nature surrounded by Shinshu mountains, is a brand pork produced by Shinshu e-Loop Business Cooperative, based in Kawanakajima-machi, Nagano City, Nagano Prefecture. Characterized by a beautiful crimson color with vivid red meat — with the character ‘Ko’ (crimson) adorning its name.
The secret of the deliciousness lies in the proprietary feed. By giving a yeast fermentation feed combining yeast, lactic acid bacteria, minerals, and food manufacturing by-products, the gut environment of the pigs is regulated and digestive absorption is elevated. Food manufacturing by-products (wheat flour, dried soba noodles, cookies, etc.) are carefully nutritionally calculated and formulated in good balance — the pigs grow healthily without getting sick. Safe, reliable pork with the use of antibiotics and medications suppressed to a minimum.
The Kurenai Suiton raised in this way is rich in unsaturated fatty acids — with a non-cloying fat and clean, refreshing finish as defining characteristics. The muscle fibers are fine — a softness that seems to crumble from the moment it enters the mouth and juiciness can be felt. With virtually no scum or off-odor, the umami can be savored to the fullest even in simple preparations like salt-grilling and shabu-shabu.
Only pigs meeting the standard of 180 days of age and 110–115 kg body weight are strictly selected for shipment. The Landrace × Large White hybrid cross has outstanding lean and fat balance — approximately 3,000 head are stably produced annually. A designated retailer system ensures reliable distribution quality — a brand pork rooted in the region as one supporting Shinshu’s rich food culture, with sustainable pig farming utilizing food cycle resources continuing.
