Storing green coffee in a humid city
Green coffee isn't frozen in time. Moisture and air slowly age it.
1. The traditional limit is 12% moisture. Research covered in Barista Hustle's processing course points to 11% as safer.
2. Water activity shows how tightly that water is held. In a long-term Cafe Imports study, coffees above about 0.61 lost quality faster, with woody notes.
3. Jute gives no barrier. In one storage trial, open jute bags rose to 13% moisture while sealed liners stayed around 11.5%.
4. Buy coffee that's properly dry, keep it sealed, cool and dry, and roast it in good time. No bag stops ageing; it only slows it.
