Beer in Niger is a small business in a country where 99.3 per cent of the people were counted as Muslims in the census of 2012. The state is secular and drink is sold, but the World Health Organization puts the consumption of an adult at 0.09 litres of pure alcohol a year in 2019 (a three-year average, drink that is not recorded included). The territory came under French rule in 1900, when the Zinder Military Territory was formed on 23 July; the civilian Colony of Niger followed on 13 October 1922, an autonomous republic within the French Community on 18 December 1958 and independence on 3 August 1960. No brewery from the colonial years has been found.

The country's one brewery stood in the industrial zone of Niamey, on the Route de Kollo, and went into service in 1967 as the Société des Brasseries et Boissons Gazeuses du Niger, Braniger. Nigerien reports say it began as a state enterprise and passed to the French Castel group in the 2000s, after privatisation; a French business directory of 1978 already shows the group Brasseries et Glacières Internationales (BGI) holding 82.66 per cent of a Braniger and 99.83 per cent of a Brasseries du Niger. Castel itself reached the BGI group in January 1990, when it bought 90 per cent of it from the Compagnie du Midi. Braniger brewed Bière Niger, a pale lager of 4.5 per cent, and the most popular local beer, Conjo, also written Conjoncture; it also bottled Coca-Cola, made soft drinks and bottled water and imported wine. Jeune Afrique says it led the market for some thirty years.

By the 2010s it was losing money. The minister of industry dated the accumulated losses from 2014 and blamed competition and fraudulent imports from the neighbouring countries; Jeune Afrique adds the ban on alcohol advertising and taxes thought too high, and the competition of private local units. At a meeting in Paris on 14 May 2019 the board decided to wind the company up, and on 20 May the manager, Xavier de Boisset, wrote to the customers that sales had also fallen since the start of the year. The government said it was ready to study any proposal that could save the plant. On 10 June 2019 an extraordinary general meeting in Niamey dissolved Braniger; de Boisset was named liquidator and the trade register was changed on 12 June. By 19 June production had already stopped. The works employed about 120 people and 200 subcontractors (Jeune Afrique); the minister counted 79 direct and 300 indirect jobs lost. Stock was to be sold off and the return of the deposit bottles went on until the end of December 2019. A national investor was said to want part of the works, without brewing or selling alcohol.

No later brewery has been found. BeerAdvocate and the Brookston Beer Bulletin (2012) list Braniger as Niger's only brewery, and OpenStreetMap still marks the plant by its name. Nothing found says what became of the works or of the Conjo name. Bière Niger is still rated on Untappd in 2025 and 2026, but by drinkers in Europe who call it a rarity, and none of the check-ins says that it is brewed again.
