The short answer
Kava is a drink made from the root of Piper methysticum, a plant in the pepper family grown across the South Pacific. It's traditionally ground, mixed with water and shared in the evening. Today you can drink it at kava bars or from a can, like Botanical Brewing's Orange Dream.

Where kava comes from

Kava grows in Fiji, Vanuatu, Tonga, Samoa, Hawaii and across the Pacific islands. For centuries it's been prepared from the root and shared at ceremonies, gatherings and the end of the day. In Fiji it's often called yaqona or simply "grog," and it's served in a coconut-shell cup with a clap and a "bula." Read more about kava culture and tradition.

What it tastes like

Traditional kava is earthy, peppery and a little bitter, and it numbs your lips slightly. That's normal. Modern canned kava, like Orange Dream or Tutti Frutti, adds fruit and bubbles so it tastes like a craft soda with an earthy finish.

Why people drink it

People drink kava to unwind and to be social, the same moments people use alcohol for, without the alcohol. Kava bars have spread across Florida and beyond, and canned kava now makes it easy to drink at home.

How to try it

What to know first

Kava isn't for everyone. Don't drink it with alcohol. Skip it if you're pregnant or breastfeeding, have liver problems, or take medication that affects the liver or makes you drowsy, and check with your doctor if you're unsure. Start with one serving and see how you feel.

Who should skip kava

  • Kava drinks are for adults 21+. Skip them if you're under 21.
  • Skip kava if you're pregnant or breastfeeding.
  • Skip kava if you have a liver condition or drink heavily. Kava has been linked to rare cases of serious liver injury.
  • Skip it if you take antidepressants (including SSRIs), sedatives, sleep aids or medications that affect the liver, unless your doctor says it's OK.
  • Rules on kava vary by place. Check your local rules before you buy.
  • One can or shell is one serving. Don't mix kava with alcohol, and don't drive after drinking it.

These are general cautions, not medical advice. If you're unsure, talk to your doctor or pharmacist.
