How should I store the 50 g pouch to keep the tea fresh, and how long does it stay good?

Fermented fireweed is more stable than green tea or unfermented herbals because oxidation has already occurred, but it still degrades with exposure to air, light, heat, and moisture. The 50 g pouch is a moderate quantity — most households will finish it in 4–8 weeks with daily use — so proper storage preserves the honey-woody aroma and prevents the leaves from absorbing foreign odors. Transfer the tea to an airtight tin or ceramic jar with a tight-fitting lid if the original pouch lacks a reliable reseal. Glass jars work only if kept in a dark cupboard; light accelerates chlorophyll breakdown and fades the amber liquor color.

Ideal conditions: 15–20 °C, relative humidity below 60 %, away from the stove, dishwasher, or sunny windowsill. Do not store near coffee, spices, scented candles, or cleaning products — fermented leaves are porous and will absorb aromatics within days. The refrigerator is unnecessary and risky: condensation forms when you open a cold jar into warm kitchen air, introducing moisture that can trigger mold. If your kitchen is very humid (above 70 %), add a food-grade silica gel packet to the jar (not loose in the tea).

Shelf life: the producer typically dates this type of product 18–24 months from production. The tea remains safe indefinitely if kept bone-dry, but the volatile aromatics — the honey, woody, dried-fruit notes — fade gradually after 12–18 months. You will notice the dry leaf scent weakening first; the brewed liquor becomes flatter, less sweet, and the amber color pales. If you detect any musty, hay-like, or sour smell, or see clumping or surface fuzz, discard the batch. For reference, 50 g yields roughly 20–25 cups at 2–2.5 g per cup, so a single-person household drinking one cup daily will turnover the pack well within the peak window.
