Bà Ba is a Vietnamese producer of traditional fermented products based in Long Điền in Bà Rịa–Vũng Tàu Province. The brand was established 1976 and has more than five decades of experience in processing marine ingredients. Its development is closely connected to the fishing tradition of the Vũng Tàu coastal area and the local availability of small marine shrimp. Production was initially based on a simple family method of salting and naturally fermenting fresh shrimp. Over time the small production facility expanded its range and introduced several package sizes intended for households and food-service businesses. The brand’s best-known product is Mắm Ruốc Bà Ba which is a fermented paste made from small marine shrimp. Its basic ingredients are fresh shrimp and salt while certain prepared varieties may also contain sugar and a flavor enhancer. Fermentation creates a thick texture, a pronounced marine aroma, and an intense salty-sweet flavor rich in umami.
