There are numerous factors to consider when developing climate-resilient coffee crops, including the ability to tolerate altered climatic conditions, meet agronomic and value chain criteria, and satisfy consumer preferences for flavour (aroma and taste). We evaluated the sensory characteristics and key environmental requirements for the enigmatic narrow-leaved coffee (Coffea stenophylla), a wild species from Upper West Africa. We confirm historical reports of a superior flavour and uniquely, and remarkably, reveal a sensory profile analogous to high-quality Arabica coffee. We demonstrate that this species grows and crops under the same range of key climatic conditions as (sensorially inferior) robusta and Liberica coffee and at a mean annual temperature 6.2-6.8 °C higher than Arabica coffee, even under equivalent rainfall conditions. This species substantially broadens the climate envelope for high-quality coffee and could provide an important resource for the development of climate-resilient coffee crop plants.
在培育具有气候适应能力的咖啡作物时，需要考虑众多因素，包括耐受气候变化的能力、符合农艺和价值链标准，以及满足消费者对风味（香气和味道）的偏好。我们评估了神秘的狭叶咖啡（Coffea stenophylla）的感官特征和关键环境要求，狭叶咖啡是一种来自西非上区的野生品种。我们证实了历史上有关其口感更优的报告，并首次独特而显著地揭示了与高品质阿拉比卡咖啡相似的感官特征。我们证明，该物种在与（口感较差的）罗布斯塔和利比里卡咖啡相同的关键气候条件范围内生长和种植，其年均温度比阿拉比卡咖啡高 6.2-6.8°C，即使在同等降雨量条件下也是如此。该物种大大拓宽了高品质咖啡的气候适应范围，可能为培育具有气候适应能力的咖啡作物提供重要资源。
