Liberica Purple Honey · Central Java, Indonesia

Purple Grape Candy · Soda · Ferment

This coffee is probably the wildest expression in the release.

Produced by JB Coffee in Temanggung, Central Java, this Liberica lot undergoes an extended inoculated fermentation before pulping, followed by a carefully controlled honey drying process designed to retain sweetness and texture while preserving clarity.

JB Coffee, led by Reza Nurullah, approaches fermentation with precision and restraint rather than simply chasing intensity. Coffee is grown within diverse agroforestry systems alongside spices, fruit trees, and native shade species.

The result is unmistakably Liberica: loud aromatics, syrupy texture, unusual fruit character, and a profile that feels somewhere between coffee, purple soda, and tropical fruit candy.

It’s intentionally unconventional and one of the coffees we were most excited to share at Cardiff Coffee Festival.
