Shelf Life
jposer Anyone know what kind of shelf life Kava has? Is there a preferred way to store it like inside of tupperware? Does refrigeration increase the shelf life?[:)]

I've seen various views on the shelf life of kava. Some say it has a shelf life of two years, others say it retains potency almost indefinitely after it has been dried. The only scientific-looking statement I've found regarding kava, shelf life, and storage is a quote appearing in a paper written by Vincent Lebot. The quote is: General guidelines for storage recommend packing in air-tight containers protected from light, heat, moisture, and insect infestation. One study found that the total kavalactone content of powdered kava stored in non-airtight, glass, screw-capped bottles at room temperature decreased by 55.0%, 33.1% and 26.2% respectively over 39, 36 and 22 months of storage. Dihydrokawain appeared to be the least stable kavalactone in kava, deteriorating by 93.9% after 39 months in storage, while methysticin was the most stable, deteriorating by 29.5% Because the kavalactones differed in their stability, the entire active constituent profile of powdered kava was altered in storage (Duve and Prasad 1983). I, on the other hand, want a study to find out what sort of person would leave perfectly good kava on their shelf for 22-39 months without drinking it? [:D]
