Last revised 18 September 2026. This guide was rewritten from a listicle into a plain comparison of kava formats. It also corrects a source that was credited to the National Institutes of Health but linked to a commercial health site, and it removes a link to a product we don't sell. What changed is listed under How we revise this guide.
Start with the honest part: we don't sell instant kava. We sell a concentrated kava extract powder you mix yourself, and three ready-to-drink tonics. If you came here looking for instant kava specifically, this page will tell you what it is and how it differs from what we make, and then you can decide.
The formats are genuinely different from each other, and almost nothing written about them online explains the difference without trying to sell you something. So here is the comparison, plainly.
The short version
- Kava comes from the root of Piper methysticum, a South Pacific plant. Every format below starts there.
- Traditional preparation means kneading ground root in water and straining it through cloth.
- Instant kava is a powder made to dissolve in water without straining. We don't sell one.
- An extract powder is concentrated, and you mix it into a drink yourself. We sell one.
- Ready-to-drink means it's already mixed and bottled. We sell three flavors and a set of all three.
- Our three tonics are made with kava root extract and Mitragyna speciosa. Our store is 21 and over.
- The National Institutes of Health reports that kava products have been linked to rare cases of liver injury, some serious or fatal, and that the FDA issued a consumer advisory about it on 25 March 2002.
- Don't mix kava with alcohol.

What instant kava actually means
Instant kava is kava root that has already been through the water-and-strain step, then dried back into a powder that dissolves when you stir it into liquid. The straining is done at the factory instead of in your kitchen.
That's the whole idea. It isn't a different plant, a different part of the plant, or a different process. It's the same preparation, moved upstream.
Worth knowing because the word "instant" gets used loosely. Some products sold as instant kava are what's described above. Others are extracts, which is a different thing, covered below. Read the label rather than the front of the bag.
Traditional preparation
The traditional method uses ground kava root, sometimes called grog when prepared. You put the ground root in water, knead it by hand, then strain it through a fine cloth. The liquid is what you drink. The spent root is discarded.
This is how kava has been prepared across the South Pacific for centuries, and it's still how it's done in the places it comes from. It takes time, it takes equipment, and it produces a drink that varies depending on the root and the person making it.
We don't sell ground kava root, so we're not the people to buy this from.
Extract powder
An extract powder is made by pulling the compounds out of the root with a solvent, usually water, then drying what's left. The result is more concentrated than plain ground root, which means the amount you'd use is different from the amount you'd use of ground root.
You mix it into water, juice, or another drink. There's no straining step because there's no plant material left to strain.
This is the category our powder sits in. It gets called instant kava sometimes, because you do just stir it into a drink, but it isn't the same product as a true instant preparation. We describe ours as an extract because that's what it is.
Ready to drink
Ready to drink means the mixing already happened and the result is in a sealed bottle. You open it. There's no preparation step at all.
Our three tonics are this format. They're made with kava root extract, Mitragyna speciosa and flavor, and they're sold chilled or at room temperature.
The tradeoff with any bottled format is that what's in the bottle is what's in the bottle. You can't change it. That's the point of it, and it's also the limitation.
The formats side by side
| Format | What it is | What preparing it involves | Do we sell it |
|---|---|---|---|
| Traditional root | Ground kava root | Knead in water, strain through cloth, discard the root | No |
| Instant kava | Root already strained, then dried to a soluble powder | Stir into liquid | No |
| Extract powder | Concentrated extract of the root | Mix into water, juice or another drink | Yes, one |
| Ready to drink | Already mixed and bottled | Open the bottle | Yes, three flavors and a set |
What we actually stock
Our whole catalog is five products. Prices are current as of the revision date at the top of this page.
| Product | Format | Sizes | Price |
|---|---|---|---|
| Raw Kava Extract Powder | Extract powder you mix yourself | 1 oz, 3 oz | $60.00 / $160.00 |
| Baja Bliss | Ready to drink, guava | 1 bottle, 3-pack, 12-bottle box | $10.99 / $29.00 / $115.00 |
| Pink Sunset | Ready to drink, cherry, strawberry and lime | 1 bottle, 3-pack, 12-bottle box | $10.99 / $29.00 / $115.00 |
| TropiColada | Ready to drink, pineapple and coconut | 1 bottle, 3-pack, 12-bottle box | $10.99 / $29.00 / $115.00 |
| Bundle | The three tonic flavors in one set | 1 set | $27.99 |
The three tonics and the Bundle are made with kava root extract and Mitragyna speciosa. Each product page carries the full ingredient list, and every report is on the lab results page. The three tonics are Lot 082026, reported 6 August 2026. The extract powder is Lot CKW-C-A508380, reported 18 August 2025, which is about a year older than the drinks. If you want to know what the numbers mean, how to read the lab report on a kratom drink you already own goes through it line by line. You can see all five in the shop.
What we don't sell
Saying this plainly, because older articles on this site are vaguer about it than they should be.
We don't sell instant kava. We don't sell ground or whole kava root for traditional preparation. We don't sell kava capsules or kava tinctures. If one of those is what you want, we're not the right shop and we'd rather say so than sell you the nearest thing.
There's also no three-bottle flavor sampler. An earlier version of this article linked to one. It doesn't exist. The closest thing we make is the Bundle.
Safety facts worth knowing
The liver is the important one. The National Center for Complementary and Integrative Health, part of the National Institutes of Health, reports that kava products have been linked to rare cases of liver injury, some of which have been serious or fatal. The NIH Office of Dietary Supplements records that the FDA issued a consumer advisory on this on 25 March 2002. Rare is not the same as never.
So: talk with a healthcare provider before using kava if you have a liver condition, take any medication, or have any health concern at all.
Don't mix kava with alcohol.
Don't drive, operate machinery, or swim after drinking one of our tonics.
Our store is 21 and over. The tonics are not for anyone who is pregnant or breastfeeding. Read the label on whatever you buy, from us or anyone else.
Rules for these products vary by state and by county, and they have moved more than once this year. Each product page lists the states and counties we can't ship that product to. Where a specific rule is worth explaining, we write it up on its own: what Minnesota's 21 rule covers, and whether North Dakota's ban covers kava drinks.
How we revise this guide
This page isn't finished, and it isn't meant to be. We revise these guides as rules change, as lab results come in, and as we learn we got something wrong. The date at the top is the point of the whole thing. If it's old, treat it as old.
When we change something, we say what changed. And if we've got something wrong here, we'd rather hear it. Send a correction to info@grassrootsharvest.com and we'll look at it.
Revision history
- 18 September 2026. Rebuilt the page as a format comparison. Removed health and effect claims throughout, along with guidance on how much to use and how long to wait. Corrected a source credited to the National Institutes of Health that linked to a commercial health site, and replaced a generic link with the specific page it was being cited for. Rebuilt the product section from the live catalog and removed a link to a product we don't sell. Added lot numbers and report dates. Retitled the page.
- 24 June 2026. First version published, carried over from our previous website.
Frequently asked questions
What is instant kava?
Kava root that has already been mixed with water and strained, then dried back into a powder that dissolves when you stir it into liquid. The straining happens at the factory instead of in your kitchen. It's the same plant and the same basic preparation as the traditional method.
Is instant kava the same as kava extract?
No. Instant kava is a strained preparation dried back to powder. An extract is concentrated, made by pulling compounds out of the root and drying what's left. Both dissolve into a drink, which is why the words get used interchangeably, but they're different products. Check the label.
Do you sell instant kava?
No. We sell one concentrated kava extract powder that you mix yourself, and three ready-to-drink tonics. We don't sell ground root, instant kava, capsules or tinctures.
What's in a GÜD Tonics drink?
Our three tonics are made with kava root extract, Mitragyna speciosa and flavor. The full ingredient list and the lab results are on each product page.
Can I drink kava with alcohol?
No. Don't combine them.
Where do you ship?
Not everywhere. Rules vary by state and by county and they change. Each product page lists the places we can't ship that product.
The short of it
Instant kava, traditional root, extract powder and ready-to-drink all start from the same plant. What separates them is where the preparation happens and how concentrated the result is. Instant means the straining was done for you. Extract means it was concentrated. Ready to drink means all of it was done for you.
We make two of those four. We've said which, and which we don't, so you can go elsewhere for the other two without wasting a trip through our shop.
