Dual extraction mushroom coffee is a phrase that describes a lab process, hot water followed by alcohol, used to concentrate beta-glucans and triterpenes from mushrooms. Most mushroom coffee, including Clarity Brew, isn't made this way. It's ground whole mushroom powder blended directly into coffee, a different ingredient than the one most research and label claims describe.
What "Dual Extraction" Actually Means in Mushroom Science
Dual extraction is a two-solvent production process, not a marketing adjective. Mushroom material goes through a hot water phase first, which pulls out beta-glucans and other polysaccharides, and then an alcohol phase, which pulls out triterpenes, sterols, and other fat-soluble compounds the water pass left behind. The liquid from both passes gets combined and dried down into a concentrate. The reason it takes two solvents instead of one comes down to basic solubility, not marketing preference.
A 2020 study on Ganoderma lucidum (Reishi) put real numbers on that split. Researchers ran two single-solvent extractions on the same batch of dried mushroom powder: a hot water bath at 95°C for two hours, repeated once, and a 95% ethanol soak at 30°C for six hours, repeated once. The water bath pulled 1.52% polysaccharide by weight. The ethanol soak pulled 0.59% triterpenoid by weight. Each solvent was doing a job the other one couldn't do well (Zheng, Zhang, and Liu, 2020, PLOS ONE).
The same researchers then tried to shortcut the process by using one compromise solvent, 50% aqueous ethanol, to grab both compound classes in a single pass. It didn't work as a shortcut. Polysaccharide yield dropped to 0.63%, well under half of what plain hot water pulled on its own. Triterpenoid yield dropped to 0.38%, also well below the ethanol-only result. Trying to do both extractions at once cost each compound class more than a third of its single-solvent yield, and in the polysaccharide's case, well over half. That's the entire reason commercial dual extraction runs two separate solvent passes instead of one blended bath: no single medium pulls both compound classes out efficiently, and a compromise solvent shortchanges both.
Why Dual Extraction Mushroom Coffee Claims Rarely Match What's in the Bag
Here's the mismatch worth naming plainly. The beta-glucan percentages, potency claims, and lab data that show up in mushroom supplement marketing are overwhelmingly generated from extracts, hot water extracts, alcohol extracts, or dual extracts, because that's the format precise enough to standardize and test. Extraction concentrates a target compound into a measurable, repeatable number. A jar of loose dried powder doesn't offer a lab the same clean starting point.
Mushroom coffee mostly isn't built from that format. Powder dominates the category: the powdered segment held the largest revenue share in the mushroom coffee market in 2025, and it's the format most brands, including Vital Pour, actually ship (Precedence Research, 2026 mushroom coffee market report). Clarity Brew is medium-roast Arabica coffee milled together with Lion's Mane and Chaga mushroom powder at a disclosed 90% coffee, 5% Lion's Mane, 5% Chaga ratio by weight. No hot water bath, no alcohol soak, no concentrate. It is dried mushroom, ground fine enough to blend evenly with ground coffee, and nothing more.
That's a genuine category mismatch, not a defect in either format. A dual extraction study measuring a Reishi or Lion's Mane concentrate is describing a different physical substance than the whole powder sitting in a bag of mushroom coffee, even when the species name on the label is identical. Applying an extract's beta-glucan percentage to a whole-powder product, or the reverse, handles two different ingredients as though they were interchangeable numbers on the same scale. They aren't. Vital Pour has not published a lab-verified beta-glucan percentage for Clarity Brew, and this article isn't going to invent one to fill that gap. The honest position is that the number doesn't exist yet in a form worth printing.
Whole Mushroom Powder vs. Dual Extract: Side-by-Side
Neither format is simply better. Each one trades concentration for completeness in a different direction.
| Whole Mushroom Powder (used in most mushroom coffee, including Clarity Brew) | Dual Extract (hot water + alcohol) | |
|---|---|---|
| What it is | Dried mushroom milled to a fine powder; no solvent step | Mushroom material processed through a hot water phase, then an alcohol phase, then dried into a concentrate |
| What it captures | The whole mushroom matrix: water-soluble and water-insoluble beta-glucans, chitin-bound fiber, everything present in the dried mushroom | The fraction of compounds that dissolve into water and alcohol, concentrated and separated from most of the fiber |
| Measured beta-glucan range in published comparisons* | Higher per gram of raw material in some studies, e.g. 22.4 to 29.8 g/100g in whole oyster and shiitake powder | Lower once the water-insoluble fraction is filtered out, e.g. 5.1 to 15.9 g/100g in the matched extracts from the same study |
| Typical use case | Blended directly into ground coffee, culinary powders, whole-food capsules | Tinctures, drops, high-potency single-mushroom capsules |
| The tradeoff | Nothing is concentrated or discarded, but some compounds stay bound in chitin that the body doesn't easily break down without a heat or solvent step | Concentrates targeted compounds and improves access to them, but no single production pass maximizes both the water-soluble and alcohol-soluble fractions, and the filtered-out fiber never reaches you either |
Comparison data from oyster and shiitake mushrooms, not Lion's Mane or Chaga specifically (See Toh et al., 2023, Frontiers in Nutrition). The direction of the finding, that extraction can lower* measured beta-glucan content by removing the water-insoluble share, is the useful takeaway here, not the exact numbers for every species.
That last row is the one most comparisons skip. It's easy to assume an extract is automatically "more" of everything, since it's sold as concentrated and priced accordingly. The See Toh study found the opposite for total beta-glucan content: extracting the polysaccharide fraction out of oyster and shiitake mushrooms actually left less total beta-glucan, by weight, than the whole dried powder started with, because the extraction step discarded the water-insoluble portion along with the fiber. Concentration and total content aren't the same measurement, and a label that only tells you one of them is only telling you part of the story.
What Actually Happens When You Brew Whole Mushroom Powder Into Coffee
Here's the part generic "extract versus powder" content never has to deal with, because it's usually written for capsule buyers, not coffee drinkers. Swallow a capsule of whole mushroom powder and your digestive system gets all of it, whatever the compounds inside, however soluble or insoluble they happen to be. Coffee doesn't work that way.
A scoop of mushroom coffee sits in a filter, a press, or a pod for a few minutes while hot water passes through the grounds. Then the spent grounds get thrown away. Only whatever dissolved into that water during that window ends up in your cup. Everything that stayed bound to the fiber goes in the compost, not your mug.
That makes ordinary brewing a small, uncontrolled version of the same hot water extraction step a lab runs deliberately. That's a point in favor of the water-soluble fraction: some portion of the beta-glucans in the mushroom powder likely does transfer into the cup during a normal brew, the same physical process at work in a hot water extraction, just without a standardized temperature, grind size, or contact time to make that transfer efficient or measurable. It is not good news for anything that needed alcohol to come loose. Triterpenes, sterols, and other alcohol-soluble compounds largely stay locked in the spent grounds, because no coffee ritual on earth follows the pour with a shot of ethanol. Whatever a genuine dual extraction's second solvent pass would have pulled out never leaves the filter basket.
This is the real, coffee-specific consequence of the extraction mismatch described above. It isn't just that mushroom coffee and dual extract are different products measured on different scales. It's that the format itself, hot water passing through grounds and then being discarded, performs half of a dual extraction automatically and skips the other half entirely, every single time, whether anyone intends it or not. A capsule bypasses this question completely, because you consume the whole powder regardless of what would or wouldn't dissolve in a given solvent. A brewed cup doesn't get that luxury. What ends up in the mug has already been filtered by solubility once, informally, before it ever reaches you.
None of this makes coffee a worse delivery method. It makes it a different one, with its own uncontrolled, single-solvent extraction event built into the ritual, rather than a deliberate two-solvent process finished at a facility before the bag was sealed. Readers who want the fuller mechanics of how mycelium- and fruiting-body-sourced material behaves once it's processed can go deeper in our guide to mycelium versus fruiting body extracts, which covers a related but distinct question: which part of the fungus the material came from in the first place.
What This Means for the Beta-Glucan Percentage on a Label
Put the extraction-method question next to the assay-method question we've written about separately, and a beta-glucan percentage on a jar starts to look like a number that needs three questions answered before it means anything comparable: which lab method measured it, was the material raw powder or a concentrated extract, and if it was an extract, was that extraction hot water only, alcohol only, or dual.
A dual-extracted concentrate's beta-glucan percentage and a whole-powder mushroom coffee's beta-glucan content are not the same kind of number, even when both are honestly measured and both name the same mushroom species. One describes a fraction pulled out and concentrated by a two-solvent process. The other describes everything that was in the dried mushroom to begin with, unconcentrated, un-fractionated, and only partly released by whatever hot water happens to pass through it at brew time. Our label-reading guide goes further into spotting which claims are actually verifiable on a package; extraction format is one more variable to check before treating any printed percentage as a fair comparison point across brands.
This is also why how much mushroom actually ends up in a scoop matters more than a percentage borrowed from an unrelated extract study. A weight-based blend ratio, the kind Clarity Brew discloses, doesn't shift depending on which solvent, assay, or brewing method someone used to measure it. It's a number Vital Pour controls directly, rather than one pulled from a lab process the finished coffee never actually went through.
Building an Honest Ritual Around What's Actually in the Cup
None of this is an argument that whole-powder mushroom coffee beats a dual-extracted mushroom concentrate, or the reverse. A dual extract genuinely concentrates targeted compounds and can make sense for someone who wants a standardized, higher-potency dose in a tincture or capsule, independent of coffee altogether. What whole mushroom powder in coffee offers instead is a simpler, more legible ingredient: dried Lion's Mane and Chaga, milled and blended at a stated ratio, brewed the same way any ground coffee is brewed, with no solvent process standing between the mushroom and the bag.
Clarity Brew is built on that second choice deliberately. Ninety percent medium-roast Arabica, five percent Lion's Mane, five percent Chaga, all disclosed by weight rather than hidden behind an undisclosed blend or a beta-glucan number borrowed from someone else's extract. It won't read as more potent on paper than a dual-extracted capsule, because it isn't measuring the same thing. It will read as a cup of real coffee with a transparent, whole-food mushroom addition, which is the tradeoff our mushroom coffee mastery guide covers from the ground up if you're still deciding whether that tradeoff suits your morning.

Frequently Asked Questions
Does Clarity Brew use dual-extracted mushrooms? No. Clarity Brew is medium-roast Arabica coffee blended with dried Lion's Mane and Chaga mushroom powder at a disclosed 90/5/5 ratio by weight. It does not go through a hot water or alcohol extraction step; the mushroom material is milled and blended directly into the ground coffee.
Is dual-extracted mushroom coffee better than whole powder mushroom coffee? Neither format is better across the board. Dual extraction concentrates specific compounds into a standardized dose, which suits tinctures and capsules. Whole powder keeps the full mushroom matrix intact and blends naturally into ground coffee, but some of its compounds stay bound in chitin that only a heat or solvent step fully releases, and normal brewing only performs part of that step.
Why don't more mushroom coffee brands say whether their beta-glucan percentage came from an extract or whole powder? Because disclosing extraction format and assay method isn't required on a supplement label, most brands don't. That's exactly why a printed percentage should be read as directional rather than directly comparable across products unless the brand states the extraction method behind it.
Does brewing coffee count as a form of extraction? In a narrow, informal sense, yes. Hot water passing through mushroom-blended grounds pulls some water-soluble compounds into the cup, similar in principle to a lab hot water extraction, just uncontrolled. It doesn't touch the alcohol-soluble fraction at all, since no coffee ritual adds ethanol to the pour, so a genuine dual extraction step never happens at the point of brewing.
