The Tanzania Coffee Research Institute (TaCRI) has introduced new coffee varieties for commercial production to boost the country's coffee production. The new varieties include high yielding, disease-resistant Robusta Coffee and 19 Arabica hybrids, as well as four compact, high-quality coffee bean varieties suitable for high density planting. These new varieties are drought tolerant and are designed for areas that had previously stopped growing coffee due to insufficient rainfall. TaCRI plans to release at least three more varieties in the near future. Tanzania ranks fourth in Africa in coffee production and is the continent's leading producer of Arabica coffee.
