Oral history says the Haya people of northwest Tanzania brought coffee from Abyssinia in the 16th century. Their coffee, called amwani, was a robusta.
They did not brew it. They boiled unripe cherries with herbs and smoked them for several days, and the result was chewed. Coffee was used in greetings, tributes to royalty and religious rituals, and growing it needed royal authorisation.
In the late 19th century German colonial laws spread coffee planting across the region. The Haya lost the wealth their coffee monopoly had given them.

- Oral history holds that the Haya brought coffee from Abyssinia in the 16th century.1
- Haya coffee, called amwani, was a robusta.1
- Growing coffee in Haya society required royal authorisation.1
- German colonial laws in the late 19th century spread coffee planting and drew the Haya into the cash economy.1

The amwani story rests on a coffee trader's page (Sucafina, 2020) citing oral history. Search snippets also mention variants (ripe cherries, cherries mixed with fat), which were not used. A scholarly source on Haya coffee could not be opened. The 'fading' status is an inference; no source states current practice.
