How should kava be stored?

Unopened, keep it in a cool dry cupboard. Once opened, refrigerate it. Kava keeps well — what wears it down is sustained exposure to heat, light and air over weeks and months, and all three are straightforward to avoid.

• Kavayn Spirits, unopened — cool, dry, out of direct sunlight
• Kavayn Spirits, opened — cool, dry, out of direct sunlight, or refrigerated
• Kavayn Snap Packs — room temperature; single-serve, so nothing to store once used
• Root powder — airtight, cool, dark, dry
• Prepared kava (root in water) — refrigerate, drink within a day or two

Refrigeration after opening does two jobs. It protects the product across its 12-month opened shelf life, and it keeps it at the temperature you want to drink it at anyway — kava is much better cold.

Sunlight is the one to avoid. A bottle left on a sunny windowsill will lose potency faster than one in a cabinet, because kavalactones break down under sustained heat and light. A dark cupboard before opening and the fridge after covers it entirely.

To be clear about timescale: this is about months, not minutes. Warming a drink doesn't meaningfully affect it. Storage is where heat actually matters.

Moisture matters most for powder. Kava root powder draws in humidity, which causes clumping and eventually spoilage. If you keep loose root, an airtight container matters more than a cool one.

Don't freeze it. There is no benefit, and freezing prepared kava affects the texture when it thaws.

Snap Packs need nothing special. Sealed, single-serve and stable at room temperature, which is most of why they travel well.
