Apong is a traditional fermented rice beverage produced primarily by the Adi people and other tribal communities of Arunachal Pradesh, northeast India. Two main variants: Nopo Apong (mild, 3 to 5% ABV, short fermentation) and Poro Apong (strong, 6 to 10% ABV, longer fermentation). Both use a traditional fermentation starter made from dried rice husks and the dried leaves or bark of Clerodendrum colebrookianum (locally known as ipoh) and related plants. Not formally GI-registered; regulated under the Arunachal Pradesh Excise Act.

What is Apong?

Apong is the rice beer of the Adi people of Arunachal Pradesh and of several related communities in the Siang, Dibang, and Lohit valleys of northeast India. It is the daily drink and ceremonial beverage of Adi culture, produced by virtually every household, served at every significant occasion, and deeply embedded in Adi cosmology and social practice.

The Adi people number approximately 140,000 and live primarily in East Siang, Upper Siang, and Lower Siang districts. Their forested valley territory is part of the Himalayan biodiversity hotspot, providing ideal conditions for rice cultivation and for the wild and cultivated plants used in Apong production.

Apong and Adi identity
In Adi society, the ability to produce good Apong is a mark of a capable and respected woman. The knowledge of fermentation starter preparation is transmitted through the female line and constitutes an important form of cultural property. Community ceremonies cannot be conducted without Apong. When development pressures and changing lifestyle patterns have affected traditional practices, the continuity of Apong production has served as one of the markers of Adi cultural resilience.

Nopo vs Poro Apong

Nopo Apong: produced from glutinous or semi-glutinous rice, fermented for 3 to 5 days with the ipoh starter. Milky-white or pale straw colour, lightly sweet and sour, 3 to 5% ABV. The everyday drink consumed at meals and carried to the fields during harvest.

Poro Apong: longer fermentation of 7 to 15 days, sometimes with multiple re-additions of starter. Deeper colour, more sour and complex, 6 to 10% ABV. Reserved for important ceremonies including weddings, the Ponung dance festival, and the Ali-Ai-Ligang agricultural festival.

The ipoh fermentation starter

The starter is a dried cake from cooked rice flour and the leaves, bark, or roots of Clerodendrum colebrookianum and related plants. Botanical mixtures vary by community. Research has documented antimicrobial compounds in the starter plants that suppress spoilage while permitting desired yeast and lactic acid bacteria fermentation. Primary microbial species: Rhizopus species (amylase), Saccharomyces cerevisiae, Candida species, lactic acid bacteria.

Regulatory Framework

The Arunachal Pradesh Excise Act includes provisions permitting tribal communities to produce traditional beverages for personal and community consumption without commercial distillery licences. Arunachal Pradesh is approximately 68% tribal by official classification, and the state’s excise framework reflects this demographic. Commercial sale of Apong requires excise licensing.

Research and Regulatory Authorities

Tamang et al. (2007 to 2020) documented the microbial communities in Apong starters: Rhizopus species, Aspergillus, Mucor (amylolytic moulds), Saccharomyces cerevisiae, Candida species (yeast), lactic acid bacteria. The Central Institute of Himalayan Culture Studies (CIHCS), Dahung, Arunachal Pradesh, has conducted ethnographic documentation of Adi fermented beverage traditions.
