About the co-ferment process

The newest frontier of processing: producers add something to the fermentation — fruit pulp, cultured yeasts, spices, or precise temperature programs — so that flavour develops into the seed rather than just around it. Done well (Amsterdam's DAK built a cult lineup on it) the results taste like candy and perfume: wildly expressive cups no terroir alone could produce. Done badly it's a costume. Purists argue it masks origin character; fans answer that it's honest, labelled, and delicious. The index takes no side — the tag simply tells you what you're getting.

How it works, step by step

  1. 1Pick ripe cherries
  2. 2Load tanks with cherries plus fruit, yeast or spice cultures
  3. 3Ferment sealed and temperature-controlled, hours to days
  4. 4Dry as a natural or wash clean, depending on the target
  5. 5Rest before hulling so the developed flavours settle
