Your guide to Thermal shock

  • What is thermal shock coffee processing?

    Thermal shock is a specialised coffee processing method that involves carefully controlled hot and cold washes to develop distinctive flavour profiles. While it’s not a fermentation method itself, thermal shock can be applied at different stages of processing according to a precise, pre-tested protocol.

    The process starts with a hot wash, which opens the pores in the coffee’s parchment and silverskin, allowing deeper penetration of flavour compounds. A rapid cold wash follows, cleansing the parchment and instantly cooling the beans. From there, the coffee is dried using a specialised mechanical system that gently removes moisture through dehydration and low-temperature carbon dioxide or nitrogen. This controlled drying phase ensures the beans aren’t exposed to excess heat or oxygen, preserving and enhancing their flavour potential.

  • How does thermal shock enhance the flavour profile of coffee?

    Once rested and roasted, thermal shock-processed coffee reveals a strikingly refined and complex taste profile. This method doesn’t just amplify flavours—it enhances their clarity and depth, often creating a cup that’s both bold and intricately layered. The process is particularly known for boosting sweetness and elevating the overall complexity of the coffee, making it a sought-after approach for those chasing exceptional and distinctive profiles.
