// Definition
The duration that hash maintains its optimal quality before terpene degradation causes 'white-out' (oxidation and drying of the surface). Dry sift has a shorter shelf life than water hash once exposed to air, and pressing hash accelerates terpene loss compared to keeping it in granular form.
// From the Episode
In Ep 023, an extended discussion about hash preservation. Bubbleman notes dry sift greases up immediately upon opening vacuum-sealed containers, while water hash gets 5-7 days. Matt the Great Gardener explains that Barb hash, no matter how dry, cakes within a 5-day window after pressing. Competition entries that white out before judging are 'not even contenders.' Vacuum sealing stops the process; freezer storage preserves for over a year.
