At Sea Spring Seeds we have the heat level tested of most (except the very mildest) chilli varieties we sell. We do this so we can provide accurate information about our chilli varieties, helping our customers decide which to buy.


Ripe chillies are harvested in August or September. We want our measurements to represent a true crop average, so we pick fruit from every plant in the crop. The whole, undamaged fruit are then dried down in a desiccator, and sent to Warwick University where all the fruit are ground into a powder and tested using the HPLC process.

Please note, these results are an indication only. Although the variety has an over-riding influence on the heat level of a chilli, individual plants and even individual fruit vary enormously. In addition, the growing environment and stage of ripeness also have significant influences on the heat level of a chilli.
