Experimental

Named fermentation experiments that aren't anaerobic, carbonic, co-fermented, inoculated, thermal shock or lactic.

Producers keep inventing fermentation methods, and most combine a few familiar steps. We list the common ones as their own techniques, so a coffee can be, say, washed, anaerobic and thermal-shocked. This page collects the rest: double fermentations, ferments with mosto saved from an earlier batch, very cold fermentations (cryomaceration), rehydrated "hydro" honeys, and methods a producer simply calls extended or gives a house name.

Expect anything from subtly sweeter versions of a washed coffee to intense, fruity, boozy cups. Because the label says little on its own, the roaster's notes on the bag are the best guide to what was actually done.

On the bag

Double fermentation
Two fermentation stages, often one in the whole cherry and a second after pulping.
Mosto
Liquid from an earlier fermentation added to a new batch as a starter, like sourdough.
Cryomaceration
Fermenting at very low temperatures, close to refrigerator-cold, often for days, to slow the microbes down.
Extended fermentation
Fermenting for longer than usual, often several days, to push fruit and sweetness.
