About Catalyst

Catalyst roasts across a broad and deliberately expressive palette, ranging from vivid tropical fruit and floral lightness through to rich chocolate, dark honey, and caramelised depth. What holds the range together is a consistent emphasis on sweetness — whether that arrives as mango sorbet brightness, coconut ganache, or fudge-like warmth. They suit drinkers who want clearly defined, generous flavour rather than subtlety for its own sake, and the range offers something considered at both ends of the roast spectrum.
