This is a question for the true kava aficionado—one who has deeply explored all the facets of kava, the many tasty and enjoyable varieties, and is now wondering what more can be done to maximize the kava experience. Is kava better fresh is certainly a question the Guru has also pondered, and when given the chance, I would say the experience of fresh kava is not to be missed!

In the South Pacific, kava brews made from fresh roots are often the norm. Though kava roots are usually dried before being sold at market or given away as gifts, in informal village get-togethers the root is often prepared fresh. This means that more effort must be put into processing the kava: while dried roots can be easily pounded into a powder using a mortar and pestle, due to their moisture content the fresh roots are more resilient and must be shredded or chewed—still a common practice in some South Pacific regions—before being steeped in cool water [1]. However, this effort may well be worth it!

There are three main reasons why kava may be even better fresh than dried: higher strength, sweeter flavor, and the certainty that you’re getting a single strain of kava. Read on as I share my guru wisdom about the points in favor of fresh kava root!

Strength: First on the list is that all-important factor when choosing kava—strength! Fresh kava root often has the reputation of being stronger than the dried root [2], and there are two very simple reasons why this is probably so. First of all, fresh kava root is, well, fresh! When you buy fresh you know for certain that the kava root was harvested from the plant only a few days ago and the kavalactones have had little time to degrade [3]. Though dried kava root or root powder lasts longer if properly stored, if it has been stored in suboptimal conditions it can lose a great deal of its strength.

The second reason fresh kava may be stronger is because it is sold whole rather than pre-ground. This has to do with surface area: once the root has been peeled, the kavalactones in kava (being somewhat volatile) can escape when exposed to the air over time. When kava root is ground into a fine powder, it creates LOTS of surface area for compounds to escape from, because each granule of kava root is exposed to air [4]. In contrast, the whole fresh root has a smaller overall surface area, which seals in most of the root matter and its constituents from the air. For a useful analogy, think about coffee beans: baristas and coffee gurus everywhere always tell us that whole bean coffee is better than ground for the same reason—whole beans lose fewer constituents to the air and thus retain their full flavor for much longer.

Single Strain: Perhaps more important to the kava connoisseur, but certainly worth noting as well, is that when you buy fresh kava root you know you’re getting a single strain of kava. Powdered kava root, as well as products like instant kava and kava capsules, may often be a blend of different kava strains rather than a single-origin cultivar. Again, this is totally fine if you simply want to use kava to relax and unwind; all kava strains have their merits and I would be overstepping my bounds by declaring one strain to be better than the others (though the Kava Guru has his favorites, heh heh). Yet if you’re interested in getting to know kava’s various strains and their individual effects, perhaps to employ them for a specific medicinal use…then obtaining whole kava root, fresh or dried, is absolutely the way to go!

Flavor: Another reason for the buzz around fresh kava root is simply that it may taste sweeter than the dried version. There’s reason to think the drying process may affect the ratio of chemical constituents in kava root (especially the older, vertical roots), resulting in a bitterer brew than that made from fresh kava root [2]. Now, kava is quite a chemically complex plant, so it makes sense that even a simple heat treatment such as sun drying could affect its overall flavor. If you’re someone who finds the taste of dried kava less than agreeable, it might be worthwhile to seek out the fresh variety.

However, don’t despair if you can’t order fresh kava where you are; there are ways to get the most out of dried kava for an experience approaching the fresh variety. Check out strains of kava known to be sweeter even when dried, such as Tongan kava or Hawaiian Mahakea kava. You can also look for kava powders with a high lateral to vertical root ratio, as the young lateral roots of kava tend to be sweeter (and may be stronger as well). To prevent your dried kava from losing strength, try buying the whole dried kava root or kava root chips and shred or grind them as needed to prepare your kava. Store dried kava powder in an airtight bag away from extremes of heat or moisture, and it should last about 3-6 months. Even better, if stored in a vacuum bag in the freezer, dried kava powder can last indefinitely!

This is difficult to believe, but it was pointed out to me recently that I’ve never actually addressed the most basic of questions regarding something as simple as what exactly Kava root is. It’s further evidence that the obvious is what often escapes me, but I will make up for that oversight by shedding some light on my favorite plant in the world!

Kava root is of course, first and foremost – a root – the root of the Piper methysticum plant. But, just what does this mean on a broader basis? Well, below are a few personal insights as to what Kava root is in its entirety, right down to its bio-constitution.

Kava Root Overview:

First off, it’s important to realize that when people refer to commercial Kava or Kava supplements more generally – they are referring to the root of the Kava plant. The other parts of the plant or aerial parts (parts above ground – not including the lateral root) are absolutely no good to us! The leaves, stem, and other sub-components of these upper parts of the Kava plant are actually hazardous to our health, as they can be poisonous [5]. It’s quite possible that these other parts of the plant are the source of the problems indicated by infamous cases of Kava and liver toxicity. There have been reported cases of Kava causing liver toxicity – cases that have since been proven to be unsubstantiated – and it’s quite possible that Kava was actually misused in these cases [4]. So, remember when discussing Kava as a supplement that is ingested, we are referring only to the Kava root and not to the entire plant. The dried Kava root used to produce Kava root powder has the highest kavalactone content at 15% of its constitution, while the rest of the root is made up of starch, fibers, sugars and proteins – which are all good things [7].

Rootstock Anatomy – Lateral vs. Underground Root:

Plant roots are composed of various parts and all plants have roots of some kind, which are responsible for many biological functions, but are primarily for nutrient and water uptake. Some vascular plants, including Piper methysticum (Kava or ‘Awa), have both lateral or aerial (above ground) roots and underground roots [6]. The lateral roots can serve many purposes, including nutrient reception from the air or even aeration of the plant.

While it is known that these lateral roots start to develop after Piper methysticum’s initial three-year maturation [3], the exact purpose of the lateral roots are unclear. However, my guru senses lead me to believe that it is likely that the aerial roots allow the plant to gain certain nutrients from sun exposure that it wouldn’t other wise have access to if all of its roots were underground. The reason I speculate this is that the amount of kavalactones in the lateral roots are increased upon sun exposure – indicating that increased sun does interact with the lateral root chemistry in some way [2, p. 40].

Given that the sun-drenched aerial roots of the Kava plant are brimming with kavalactones (more so than the underground roots), the most potent/strongest Kava is made from these lateral roots. Kavalactones are the compounds in a Kava plant that are to be thanked for all of the wonderful benefits and pleasurable outcomes of having a Kava root beverage [1] – so, it’s no wonder that processes of cultivation have led us to be more attracted to the potent aerial roots!

Although underground roots are also used in the production of Kava supplements and are more abundant than the lateral roots [3] – they aren’t the best option when it comes to choosing what Kava supplements you would like to take. There are a host of reasons as to why the lateral roots are used more often. For one, underground roots are less potent, as mentioned above. Additionally, they are more difficult to harvest. Furthermore, on more of a tragic vein – much of the plant must be destroyed in order to get at the underground roots [3]. Why would we want to destroy a plant to get at the less beneficial parts, when we could just snip away at the lateral roots and get a higher quality Kava root? We wouldn’t! That’s why the highest quality and morally intact Kava supplement you can get is from the lateral Kava root, while the underground root is used in the cheaper, lower-quality options.

Kava Variants:

Many years of cultivation and genetic pruning of the Piper methysticum plant have allowed it to travel and grow in regions of the planet that are best suited to its prime development. The wild version of Piper methysticum – Piper wichmannii – hasn’t had the care and tender support of educated farmers and as a result tends to have lower amounts of kavalactones. This is why Hawaii has become known as a prime source of Kava root – it has all of the resources to cultivate and care for the highest quality of Kava [2, p. 40]!

Different varietals of the Piper methysticum plant have different levels and types of kavalactones, but the Hawaiian varietals – or the cultivars primarily used in growing Kava in Hawaii – have been developed over the years to have the highest quantity of potent kavalactones. There are three kavalactones in particular that Hawaiian cultivars are known for: kavain, methysticin, and dihydrokavain. And no wonder Hawaii is known for its Kava – those three kavalactones have been dubbed as the perfect concoction for “fast-acting and pleasant experiences” [2, p. 31]!

According to Wikipedia, “…one of the most potent strains of Kava is called ‘Isa’ in Papua New Guinea, and also called ‘Tuday’ in Hawaii. In Vanuatu, it is considered a type of ‘Tudei’ kava, pronounced as ‘two-day’ because it is said to have effects lasting two days due to its chemical profile being high in the kavalactone dihydromethysticin. The plant itself is a strong, very hardy, fast-growing variety with multiple light to dark green stems covered with raised dark spots.”

When it comes to kava, though, “most potent” certainly does not necessarily mean it’s the best. If you’re curious to find out why, read some Facebook comments regarding this topic, the Kava Forums Tudei post with an opposing viewpoint, or a recent study regarding “Flavokawain B, the hepatotoxic constituent from kava root“.

What About Those Kavalactones?:

According to James A. Duke, “Phytochemicals called kavalactones produce kava’s stress-beating, muscle-relaxing influence. Each produces a somewhat different physiologic effect in the body and all of them working together are better than any of them acting alone.” [8]

For someone who simply enjoys Kava as the best natural means I know of to calm my mind outside of meditation or surfing, what had intrigued me most about these mysterious kavalactones, are finding out which ones are most responsible for the pleasurable effects of Kava. Many years ago, just some cursory digging in my favorite Kava books got me the answer I wanted and in detail, summarized below.

In 1989, the true guru of Kava; Vincent Lebot and J. Lésque and a subsequent paper entitled “The origin and distribution of Kava (Piper methysticum Forst. f., Piperaceae): A phytochemical approach”, they assigned numbers to the 6 major kavalactones. As mentioned above, there are about 18 known lactones in Kava, but just 6 of these account for 90% of the total Kavalactone content, and subsequently, for most of the effects Kava produces.

These 6 major lactones are as follows:

1 = desmethoxyyangonin
2 = dihydrokavain
3 = yangonin
4 = kavain
5 = dihydromethysticin
6 = methysticin

These 6 numbers have become the accepted system for not only identifying the overall amounts of Kavalactones in relation to each other within a single sample of Kava Root, but the 6 digit code that is generated from a single Kava sample can also be used to identify its geographical location. How? Well, each region of the world produces a very unique cultivar of Kava due to it’s own unique weather patterns, sunlight intensities, soil composition, and even the elevation that the Kava plant grows. All of these factors, including human propagation and selection over the past 3,000 years, gives Kava a distinct “fingerprint” that is extremely consistent in the Kavalactone content within that regions main cultivar of Kava. And it’s the combination of the 6 major kavalactones that provide the range of effects.

One example of this is the Borogu Kava variety from the Islands of Vanuatu. This particular variety is famous for its psychoactive effects throughout Oceania – effects that those who have purchased products from cbdandshrooms may know something about. It has the 6-digit sequence of 245613, with dihydrokavain followed by kavain as its highest concentration kavalactone constituents [9]. Those seeking for “happy” kava, typically seek out the Vanuatu cultivar of Kava, and specifically the Noble Vanuatu variety. “Noble” is a name that’s reserved for just a few cultivars of Vanuatu Kava. They are prized for their excellent “drinkability” as well as the quite noticeable effects on the mind. We know that Bula Kava House offers only Noble varieties of Vanuatu Kava, as does Kava Dot Com.

And In Closing:

Now you have more than a basic understanding of what the Kava root is when it comes to the drinking kind of Kava root. You also now know the important distinction between lateral root and underground root and can do your research on various vendors to determine which one has the highest quality of Kava as well as the Kava with the “Kavalactone lineup” that you prefer most. If you choose to go with lower quality products that is, of course, up to you – but do remember that it’s always wise to be advised. Whether you choose the Tudei Kava, go with a Noble Vanuatu cultivar, or find a Fijian Kava that, as Bula Kava House says offers “an inner warmth and mental bliss”, part of the joy of Kava and the many varieties found around the web is simply trying out as many as you can, and discovering your own ‘awa ‘uhane (Kava spirit) in the process!
