Everything you actually need to know about Kava.
Kava is a Pacific plant and traditional beverage with a history stretching back thousands of years. But kava is also an agricultural product, and no two cultivars, farms, harvests, or lots are exactly alike.
Kava, in short
Kava is Piper methysticum, a perennial shrub in the pepper family grown across the islands of the Pacific. The drink made from its roots is also called kava.
The roots are ground, kneaded in cool water, and strained through a cloth bag. What passes through is an opaque, earthy, peppery beverage, served in a coconut shell and traditionally drunk in one go. Across Polynesia, Micronesia and Melanesia it has been drunk for roughly three thousand years to open discussion, welcome guests, settle disputes and mark occasions of consequence.
Drinkers describe muscular relaxation and a sociable, settled calm with thinking largely intact — the difference from alcohol that people cite most often. Beyond that, the specifics matter enormously, and that is what the rest of this guide is for.
