Kava has been served as a drink for a very long time. Long before functional beverages filled refrigerator shelves, Pacific Island communities were preparing kava for social, ceremonial, and cultural occasions.
So, what is a kava drink?
Traditionally, it’s a beverage prepared from the underground parts of Piper methysticum, a plant native to the South Pacific. Today, the term can also describe modern ready-to-drink beverages and other products formulated with kava or kava-derived ingredients. NCCIH
That means the tropical can you spot in a cooler and a traditionally prepared bowl of kava may share an ingredient, but they shouldn’t be treated as the same experience.
Here’s where kava comes from, what makes it interesting, what researchers actually know, and why it’s showing up in a new generation of functional drinks.
What Is a Kava Drink?
To understand a kava drink, it helps to start with the plant.
Kava’s botanical name is Piper methysticum. It belongs to the pepper family and is native to the South Pacific. Pacific Island communities have consumed kava beverages for thousands of years, including in ceremonial and social settings. NCCIH
Traditional preparation generally involves processing the underground parts of the plant and mixing them with water to create a beverage.
Modern kava products are considerably more varied. Depending on the product, you may encounter kava in powders, dietary supplements, extracts, beverages, or ready-to-drink functional formulas. Kava bars have also become established in parts of the United States. NCCIH
So when someone says “kava drink,” context matters.
Where Does Kava Come From?
Kava’s story begins in the Pacific, not in the supplement aisle.
The plant has deep cultural significance across multiple Pacific Island communities, where beverages made from kava have been consumed for social, ceremonial, and other traditional purposes for generations. NCCIH describes Pacific Island use of kava beverages as extending back thousands of years. NCCIH
That history deserves more than a passing mention.
Modern wellness culture has a habit of discovering an ingredient and immediately reducing it to a benefit: this plant for stress, that mushroom for focus.
Kava is a good reminder that plants can have cultural histories much richer than the claims that eventually appear around them.
Understanding where an ingredient comes from is part of understanding the ingredient.
What Are Kavalactones?
You’ll probably encounter this word if you spend much time reading about kava: kavalactones.
Kavalactones are naturally occurring compounds found in kava and are considered important contributors to its biological activity. Research into kava extracts and preparations often considers their kavalactone content. PubMed Central (PMC)
But that doesn’t mean every kava product contains the same amount or profile of these compounds.
The plant material used, cultivar, preparation method, extraction process, and formulation can differ.
That’s one reason research involving a particular standardized kava extract shouldn’t automatically be used to describe the effects of every kava drink on the market.
Same plant doesn’t necessarily mean same preparation.
And same preparation doesn’t necessarily mean same finished product.
What Does a Kava Drink Feel Like?
This is probably one of the first questions someone curious about kava will ask.
It’s also one where we should be careful about promising a universal experience.
Kava has traditionally been consumed in social and ceremonial contexts, and modern research has investigated certain kava preparations primarily in relation to anxiety. But individual responses can vary, and the composition and amount of kava differ across products. NCCIH
So it would be misleading to say every kava beverage will make everyone feel a specific way.
There’s also an important difference between describing traditional use, studying a standardized extract in a clinical trial, and evaluating a finished multi-ingredient functional beverage.
Those are three different things.
What Does the Research Say About Kava?
Kava is more than a traditional botanical. It has also been the subject of human clinical research.
Much of that research has focused on anxiety.
And the evidence is interesting, but not perfectly consistent.
Earlier randomized trials and reviews reported reductions in anxiety measures with some kava extracts. For example, a 2013 randomized controlled trial found improvement over placebo using an aqueous kava extract in participants with generalized anxiety disorder. PubMed
But a larger 16-week randomized trial published later did not find kava significantly more effective than placebo for generalized anxiety disorder. PubMed
A systematic review likewise concluded that the available evidence was promising but insufficient to confirm an effect beyond placebo for generalized anxiety disorder. PubMed
That gives us a much more accurate takeaway than “kava reduces anxiety.”
Certain kava preparations have been studied for anxiety, with mixed findings across clinical trials.
And importantly, those studies do not establish that a particular canned kava beverage treats anxiety.
Traditional Kava vs. Modern Kava Drinks
This distinction deserves its own section because the words can make very different products sound interchangeable.
A traditional kava beverage has a particular cultural history and preparation context.
A modern kava drink might be ready-to-drink, flavored, carbonated, combined with other functional ingredients, or formulated using a particular kava ingredient or extract.
Neither description automatically tells you:
- how much kava the product contains,
- which cultivar or plant material was used,
- how it was processed,
- its kavalactone content,
- or what other functional ingredients are in the formula.
That’s why the ingredient panel and product information matter.
“Kava” tells you where to start asking questions.
It doesn’t tell you everything about what’s in the bottle or can.
What Does Kava Taste Like?
Traditional kava isn’t famous for tasting like pineapple candy.
Its natural flavor is generally earthy and distinctive, which is one reason modern beverage makers often pair kava with stronger or brighter flavor profiles.
That opens up an interesting creative space.
Instead of asking people to approach a functional ingredient purely because of what it might do, a beverage can also start with a much simpler proposition:
Does this actually taste good?
For Groovy, that means kava appears across three very different mocktail-inspired flavor profiles:
Social, Pineapple Tiki takes things tropical.
Unwind, Moscow Mule leans into ginger and citrus.
Nightcap, Blackberry Mojito moves toward darker berry and mojito-inspired flavor.
Same shared botanical.
Three very different drinks.
Why Is Kava in Functional Beverages?
Kava sits at an unusual intersection.
It has a long history as an actual beverage ingredient. It has cultural associations with social and ceremonial drinking. And it has attracted modern scientific interest.
That makes it a natural point of curiosity for the functional beverage category.
But the best way to talk about that relationship isn’t to pretend kava is a newly discovered wellness hack.
It isn’t.
Nor should a kava drink automatically be framed as a medicine, treatment, or guaranteed route to relaxation.
A more grounded approach is to understand kava as a culturally significant South Pacific botanical with naturally occurring kavalactones and an evolving body of modern research.
That story is already interesting enough.
How Kava Fits Into Groovy Drinks
Kava is the one functional ingredient shared across Groovy’s current drink lineup.
But that doesn’t mean Social, Unwind, and Nightcap are three versions of the same formula.
Social, Pineapple Tiki
Social combines kava with caffeine, ginseng, L-theanine, and lion’s mane.
The flavor goes bright and tropical with Pineapple Tiki, making Social the more daytime and get-together-oriented member of the lineup.
Unwind, Moscow Mule
Unwind combines kava with 5-HTP, GABA, lemon balm, and lion’s mane.
Its Moscow Mule-inspired profile brings ginger and citrus into the picture, fitting naturally into slower evenings and changing gears after the day.
Nightcap, Blackberry Mojito
Nightcap combines kava with melatonin, chamomile, tryptophan, and magnesium.
Blackberry Mojito takes the flavor darker and fruitier, while the formula distinguishes Nightcap as Groovy’s nighttime-oriented drink.
The important SEO and editorial distinction here is also a useful consumer distinction:
kava is part of each formula. It isn’t the entire formula.
Is a Kava Drink the Same as an Adaptogenic Drink?
Not necessarily.
The language around functional beverages can get loose pretty quickly, with terms like adaptogen, functional ingredient, botanical, and nootropic sometimes thrown into the same bucket.
They aren’t synonyms.
Kava is a botanical. Some contemporary wellness discussions place it alongside adaptogens, but forcing every functional botanical into the adaptogen category can obscure more than it explains.
A kava beverage can also contain ingredients that clearly aren’t adaptogens at all.
Social contains caffeine.
Nightcap contains melatonin and magnesium.
Unwind contains GABA.
That’s why functional drink is often the more useful umbrella term when talking about formulas containing several different types of ingredients.
If you want the deeper version, our guide to adaptogenic mocktails breaks those categories down further.
Is Kava Safe?
This is an important part of the conversation.
Kava products have been associated with rare cases of liver injury, including some serious cases. Researchers have proposed several possible contributing factors, including preparation methods, plant varieties or parts, contamination, concurrent alcohol use, individual susceptibility, and prolonged or high intake, but the issue isn’t fully resolved. Cases have also been reported with aqueous preparations, so it would be inaccurate to say traditional-style water preparation eliminates the risk. NCCIH
NCCIH also advises that kava should not be combined with other substances that have sedative effects, including alcohol and benzodiazepines. Kava may interact with medicines, and there are particular concerns around pregnancy and breastfeeding. NCCIH
That doesn’t make kava uniquely scary.
It means “natural” shouldn’t be interpreted as “no context required.”
Read the product information. Follow its directions. And if you take medications, have a health condition, are pregnant or breastfeeding, or have questions about whether kava is appropriate for you, talk with a qualified healthcare professional.
What Should You Look for in a Kava Drink?
Start with the actual product rather than the buzzword.
Look at what else is in the formula. Check whether it contains caffeine, melatonin, other botanicals, amino acids, vitamins, minerals, or additional functional ingredients.
Consider when you plan to drink it.
And pay attention to flavor.
That last one sounds obvious, but functional beverages sometimes become so focused on ingredients that drinking the drink feels strangely secondary.
Groovy takes a different route: the functional ingredients matter, but so does Pineapple Tiki, Moscow Mule, or Blackberry Mojito actually being something you want to sip.
Educate first.
Then pick the flavor that sounds good.

Is a kava drink the same as alcohol?
No. Kava and alcohol are different substances. NCCIH specifically advises against using kava together with alcohol because both can have sedating effects. NCCIH
Does kava treat anxiety?
Certain kava extracts have been investigated for anxiety, but clinical findings are mixed. Some trials have reported benefits while others have not, and current evidence shouldn’t be used to claim that a finished kava beverage treats anxiety. PubMed
Which Groovy drinks contain kava?
Kava is included in all three current Groovy drinks: Social, Pineapple Tiki; Unwind, Moscow Mule; and Nightcap, Blackberry Mojito.
An Old Botanical in a New Kind of Drink
A kava drink might feel like part of the latest functional beverage trend, but kava itself is anything but new.
Its roots reach back through generations of Pacific Island cultural and social traditions. Modern research has added another layer to that story, while contemporary beverage makers are exploring ways to bring kava into flavors and formats that look very different from traditional preparations. NCCIH
That doesn’t mean every kava drink is the same.
It means there’s more worth knowing than what fits on the front of a can.
And around here, learning what’s inside can be part of the Groove.
