Decaf and Caffeine-Free Mushroom Coffee: Every Brand's Decaf, How Much Caffeine Is Left, and When 100 mg With Theanine Is the Better Cup

Short answer: yes, decaf mushroom coffee exists, and so do caffeine-free mushroom drinks, but they are three different things and the labels blur them. Decaf mushroom coffee is real coffee with the caffeine taken out and mushrooms stirred in: Laird Superfood, Four Sigmatic and Cuppa each sell one, and by USDA's table a brewed decaf still carries about 2 mg of caffeine a cup¹, with measured samples running up to 14 mg in a 16 oz serving². Caffeine-free mushroom "coffee" is usually a drink that was never coffee: chicory, rooibos, cacao or herbs with mushroom extracts, printed at zero. And a third group, the 5 to 48 mg cups from Beyond Brew, MUD\WTR, Everyday Dose and RYZE, gets called caffeine-free in conversation and is not. This guide reads every one of them from the brand's own catalogue on 7 November 2026, explains what "decaf" leaves behind and how it is made, says who should actually skip caffeine, and is honest about one more thing: Alphacino is not decaf. It is a 100 mg robusta with 100 mg of L-theanine, built for the reader who wants the lift without the edge rather than no lift at all³.

Is there a decaf mushroom coffee?

Yes, three that we can find from brands that print what they sell, and we read each one on its own product page on 7 November 2026. Laird Superfood's PERFORM Decaf is its Peruvian organic coffee, decaffeinated by the Swiss Water Process, with the same four mushroom extracts as the caffeinated PERFORM (lion's mane, chaga, cordyceps and maitake), $20 for a 12 oz bag⁴. Four Sigmatic sells two: Calm Decaf Ground Coffee, a Swiss Water decaf with reishi and chaga, $20 for a bag the page counts as 13 servings, and Focus Decaf Coffee Pods, a Swiss Water dark roast with lion's mane for Keurig machines, $36 for 24⁵. Cuppa sells Decaf Healthy Coffee, an instant arabica decaffeinated with water and activated charcoal that the brand calls "99%+ caffeine-free", $25 for 30 servings⁶. Our reviews of Laird, Four Sigmatic and Cuppa read the caffeinated versions label by label.

What none of the three prints is how much caffeine is left. "Decaf", "99%+ caffeine-free" and "minus the caffeine" are the phrases on the pages, and none is a number. The next section supplies the numbers from the sources that have measured them.

How much caffeine is in decaf mushroom coffee?

Decaf is not zero, and the gap between "decaf" and "caffeine-free" is the most useful thing on this page. USDA's reference table puts brewed decaffeinated coffee at 1 mg of caffeine per 100 g, which is about 2 mg in an 8 oz cup, against 40 mg per 100 g and about 95 mg a cup for regular brewed coffee¹⁸. Decaf instant coffee prepared with water is also 1 mg per 100 g, and so is decaf espresso⁹. Those are averages. When a toxicology lab bought ten decaffeinated coffees from different outlets and measured them, they ran from 0 to 13.9 mg per 16 oz serving, and six decaf espresso shots from one outlet ran from 3.0 to 15.8 mg a shot². The authors' point was for people on caffeine-restricted diets: a drink sold as decaffeinated may still contain caffeine, in an amount that varies from cup to cup.

So the honest range for a decaf mushroom coffee is about 2 mg a cup on the table and up to about 14 mg in a large one. Cuppa's "99%+ caffeine-free" is consistent with that: the caffeinated Cuppa prints about 70 mg a cup (see our Cuppa review), so one percent of it is under a milligram, and the brand's own FAQ says the process "leaves behind only microscopic traces of caffeine that you won't feel"⁶. Laird and Four Sigmatic print no figure at all, which they should. For scale, a single 48 mg serving of RYZE is twenty or more decafs¹⁰, and a scoop of Alphacino at 100 mg is fifty³.

Does that residue matter? For most people, no: 2 to 14 mg is below the roughly 40 mg at which the research record starts to show caffeine improving alertness and attention¹¹. For someone told to avoid caffeine entirely, or who reacts to small doses, it is a reason to prefer the drinks in the "true zero" section below, which contain no coffee, tea or cacao and are printed at zero.

How decaf is made: Swiss Water, carbon dioxide and solvents

Caffeine is removed from green coffee beans before roasting, and the methods fall into three families: organic solvents, water, and supercritical carbon dioxide¹². The solvent methods soak the beans and pull the caffeine out with methylene chloride or ethyl acetate; US regulations permit methylene chloride to remain in decaffeinated roasted coffee and decaffeinated instant coffee as a residue at up to 10 parts per million¹³. The carbon dioxide method uses pressurised CO2, which leaves no solvent behind. The water methods, of which Swiss Water is the trademarked one, soak the beans in water to draw out a caffeine-rich extract, run that extract through activated charcoal to trap the caffeine, and reuse the flavour-rich water on the next batch, so the beans lose caffeine but keep most of their soluble flavour; Laird's and Four Sigmatic's decaf pages describe exactly this⁴⁵, and Cuppa describes the same water-and-charcoal idea under its own name⁶.

Two things follow. First, "chemical-free" on a decaf label is a claim about the process, not about the caffeine: a Swiss Water decaf carries the same few milligrams as any other decaf. Second, all three mushroom decafs we found use a water process, so the solvent question does not arise with any of them, whatever you make of a 10 ppm residue limit. If you buy a decaf from another brand and it does not say how it was decaffeinated, it is worth asking.

Caffeine-free mushroom coffee that was never coffee

Most of what is sold as "caffeine-free mushroom coffee" contains no coffee. That is not a trick; it is the only way to reach zero, because every decaf keeps a trace. These products build a dark, roasted-tasting drink from something else and add mushroom extracts to it.

Three notes on that table. Chicory has been "well known as a coffee substitute" for a long time, as a pharmacology review of the plant puts it¹⁹, which is why RYZE and others reach for it, and RYZE prints its chicory blend at zero caffeine¹⁴. Herbal teas such as rooibos are 0 mg of caffeine in USDA's table⁹, so a rooibos blend is a true zero too. Cacao is the exception people miss: unsweetened cocoa powder carries 230 mg of caffeine per 100 g⁹, so a 5 g tablespoon is about 12 mg, which is why the cacao-based cups sit in the next section rather than this one. If what you want is a coffee alternative for energy rather than a zero, our coffee alternatives guide ranks the options by what they actually contain.

Low-caffeine cups that get called caffeine-free

The third group is where most of the confusion lives. These are real coffees or cacao drinks with less caffeine than a cup of coffee, sold with phrases like "a fraction of the caffeine" or "jitter-free", and asked about online as if they were caffeine-free. They are not, and the amounts are worth knowing because they decide whether the drink is an evening drink.

Two of those brands are worth a sentence because the questions keep coming. RYZE does not make a decaf coffee: its coffee is 48 mg a serving, and its caffeine-free product is the Mushroom Chicory in the table above, which is not coffee¹⁰¹⁴. Our RYZE review covers the coffee itself. Everyday Dose does not make a decaf either: on 7 November its coffees were 45 and 90 mg, its matcha 40 mg, and the only 0 mg lines on its shop page were the creamers²¹. The reviews of Beyond Brew, MUD\WTR and Everyday Dose read each label in full, and our caffeine-by-brand guide puts every brand on one table.

Who should actually skip caffeine, and who only thinks they should

Decaf is the right call for a few groups, and the reasons are specific. In pregnancy, the American College of Obstetricians and Gynecologists' committee opinion puts moderate consumption at under 200 mg a day²³, and a decaf mushroom coffee at 2 to 14 mg sits comfortably under it; the mushroom and herb side of any of these drinks is a separate question to put to a clinician. With high blood pressure, a 200 to 300 mg dose of caffeine raised systolic pressure by a mean 8.1 mmHg and diastolic by 5.7 mmHg in hypertensive adults in five trials, an effect that appeared within the first hour and lasted three hours or more, while two weeks of coffee did not raise blood pressure against decaf or a caffeine-free diet²⁴; across 16 randomised trials of a week or longer, coffee and caffeine raised systolic pressure by a pooled 2 mmHg, more for caffeine alone than for coffee²⁵. If you have been told to watch your pressure, the acute rise is the one that matters, and decaf avoids it. Our side-effects guide covers the blood pressure questions people ask about mushroom coffee specifically.

Anxiety is the third clear case. A 2024 meta-analysis of 14 study arms in healthy adults found caffeine intake raised anxiety scores against control, especially at higher intakes²⁶. Sleep is the fourth, and it is about timing as much as dose: a meta-analysis of 24 studies found caffeine cut total sleep time by 45 minutes and sleep efficiency by 7%, and concluded that a 107 mg cup of coffee should be at least 8.8 hours before bed to avoid losing sleep²⁷; in a home study, 400 mg taken even six hours before bed still disrupted sleep against placebo²⁸. A decaf at 9 pm clears both bars; a 45 mg "low-caffeine" cup at 6 pm does not clear the first one for an 11 pm sleeper. The timing guide works the cut-off times through brand by brand.

Then there is sensitivity, which is real and personal: caffeine's half-life and clearance vary several-fold between people in the pooled pharmacokinetic data²⁹, so the same 100 mg is gone from one person by dinner and still circulating in another at midnight. If a single coffee gives you a racing heart or a bad night, that is your dose, whatever the population averages say. And for anyone on a prescription with a caffeine restriction, the decaf-residue study above was written for you: the lab measured those decafs because patients on certain medications are advised to stop caffeine and substitute decaf, and found caffeine in most of them².

Who only thinks they should? The person who has a mid-afternoon coffee, sleeps badly, and concludes caffeine disagrees with them. Usually the problem is the clock, not the molecule: moving the last cup to before 2 pm fixes it for an 11 pm bedtime by the 8.8-hour rule, and nothing else has to change. The caffeine limits guide sets the daily and single-dose lines, 400 mg a day and 200 mg at a time for healthy adults by the European food safety authority's review³⁰, and a 100 mg mushroom coffee uses a quarter of the day.

What you give up with decaf, and what you keep

Be clear-eyed about what a decaf mushroom coffee does on day one: nothing you can feel. The lift from any mushroom coffee is the caffeine. From about 40 mg upward, caffeine improves alertness, vigilance, attention and reaction time in the research record¹¹; at 2 mg it does not. The mushrooms work on a clock of weeks, if they work at the dose in the cup: lion's mane improved cognitive scores in older adults after 16 weeks at 3 g a day of fruiting-body tablets, and the gain faded four weeks after they stopped³¹; a single 1.8 g dose sped up a Stroop task at 60 minutes in young adults, with a trend to lower stress after 28 days³². Those are grams. The decafs in the first table carry about half a gram of four mushrooms (Laird) or unprinted amounts (Four Sigmatic, Cuppa). The Om booster, at a printed 2,000 mg of lion's mane, is the one product in this guide that reaches the trial range, and it is a powder for your own coffee rather than a coffee.

If you switch from a caffeinated cup to decaf, expect withdrawal first. In the review that validated the syndrome, headache occurred in 50% of people in experimental studies, symptoms began 12 to 24 hours after stopping, peaked at 20 to 51 hours and lasted 2 to 9 days, and doses as low as 100 mg a day were enough to produce them³³. A week of tapering, by mixing caffeinated and decaf grounds, is the usual way round it.

What you keep is the coffee. The long-term associations people cite for coffee mostly survive decaffeination, which points at the bean rather than the caffeine. In a meta-analysis of 28 cohorts with over a million participants, each daily cup of caffeinated coffee went with a 9% lower risk of type 2 diabetes and each cup of decaf with 6%³⁴. In the UK Biobank, with nearly half a million people followed for ten years, coffee drinking was inversely associated with all-cause mortality, and the authors report similar associations for instant, ground and decaffeinated coffee and regardless of a genetic caffeine-metabolism score³⁵. The umbrella review of coffee and health found the largest risk reductions at three to four cups a day across most outcomes³⁶; it pooled coffee as a whole and does not separate decaf, so read it as evidence about coffee rather than caffeine. None of this is a trial, and none of it is about the mushrooms, but it does mean a decaf drinker is not giving up whatever coffee itself is doing.

When 100 mg with theanine is the better cup

Here is where we declare an interest. Alphacino is a caffeinated robusta: 100 mg of caffeine a scoop, printed, with 100 mg of L-theanine beside it, 500 mg of lion's mane fruiting-body extract, 600 mg of KSM-66 ashwagandha, 224 mg of black maca and 50 mg of S7³. It is not decaf, it is not low-caffeine, and if you are in any of the groups in the "who should skip caffeine" section it is not for you; the decafs and the true zeros above are.

It is for the much larger group whose actual complaint is not caffeine but the edge that comes with it: the jitters, the 3 pm crash, the afternoon cup that costs sleep. The theanine is there for the first of those. In a placebo-controlled trial of 44 young adults, 97 mg of L-theanine with 40 mg of caffeine improved accuracy during task switching and self-reported alertness and reduced tiredness at 20 and 70 minutes³⁷. A full 100 mg of caffeine is the dose that produces the alertness effects in the record¹¹ rather than the 2 mg that does not, and 100 mg is a quarter of the daily ceiling and half of the single-dose line³⁰. The crash and the sleep cost are timing problems, solved by the 8.8-hour rule²⁷: one scoop before 2 pm for an 11 pm bedtime, and the day is done. The ashwagandha is the part that works on the stress side of the same complaint, on a clock of weeks: 600 mg a day of the KSM-66 extract for 60 days lowered stress scores and serum cortisol against placebo in a randomised trial of 64 adults³⁸, and that is the dose in the scoop.

So the fork is simple. Told to avoid caffeine, or drinking after 2 pm: decaf or a true zero, and the Om booster if you want a trial-range mushroom dose with your own decaf. Want the morning lift without the edge, before 2 pm: a caffeinated cup with theanine and printed doses, which is what we make.

Alphacino against the decafs and the zeros, label to label

Where the decafs win: price (Laird at 59 cents is a third of our cup), organic certification, and of course caffeine, for the reader who must avoid it. Where Alphacino wins: the printed doses, the theanine, an ashwagandha dose at the trial level, and a guarantee twice as long as Laird's. Where nobody wins: not one of the five prints the beta-glucan content of its mushrooms, which is the number that would settle whether any of these extracts does anything at these amounts.

Who should pick which

• Pregnant, hypertensive, anxious, on a caffeine restriction, or drinking after 2 pm: a true zero first (RYZE Mushroom Chicory, MUD\WTR :rest, Four Sigmatic's cacao or blends, Rasa Original), a water-process decaf second (Laird, Four Sigmatic, Cuppa), accepting the 2 to 14 mg. Check the mushroom and herb side with your clinician if you are pregnant.
• You want a real coffee at night: Laird PERFORM Decaf at 59 cents a cup or Four Sigmatic's Focus Decaf pods if you own a Keurig; both are Swiss Water. Cuppa if you want instant.
• You want a mushroom dose at a trial level and no caffeine: Om's Focus Coffee Booster, 2,000 mg of lion's mane a serving, brewed with your own decaf grounds. Nothing else in this guide reaches that figure caffeine-free.
• You want to cut down, not out: Everyday Dose Mild, Laird Mushroom Instant or RYZE at 45 to 48 mg, drunk before noon; or taper a 100 mg cup by mixing it half and half with a decaf for a week, which also softens the withdrawal.
• You want the morning lift without the edge: a caffeinated cup with theanine, taken before 2 pm. That is Alphacino, and we have said three times now that it is not decaf.

Where Alphacino fits

We are a product website, so here is the plain version. If you came to this page because caffeine is off the table for you, buy one of the decafs or zeros above; we would rather you had the right cup than ours. If you came because the usual cup leaves you jittery, crashing or awake at midnight, the fix is usually a smaller, earlier, theanine-paired dose rather than no dose, and that is what Alphacino is: 100 mg of robusta caffeine with 100 mg of L-theanine, 500 mg of lion's mane extract, 600 mg of KSM-66, 224 mg of black maca and 50 mg of S7, every figure on the label, $49.97 for 30 cups with a 60-day guarantee³. One scoop before 2 pm, nothing after. If a decaf guide is where you decide to try it, that is the honest way to get there. Our best mushroom coffee guide ranks seven brands by the label if you want the wider field, and the lion's mane coffee guide covers the one mushroom with human trials behind it.

Frequently asked questions

Is there a decaf mushroom coffee?

Yes. Laird Superfood's PERFORM Decaf (ground, Swiss Water), Four Sigmatic's Calm Decaf ground coffee and Focus Decaf pods (Swiss Water), and Cuppa's Decaf Healthy Coffee (instant, water and charcoal) are the three brands we found selling one on 7 November 2026. None prints how much caffeine is left.

Is mushroom coffee caffeine-free?

Not unless it says decaf or is not coffee at all. Mushroom coffee is coffee with mushroom extract added, so it carries whatever caffeine the coffee does: 45 to 100 mg a serving across the brands. Decaf versions carry about 2 mg a cup and up to about 14 mg; the only true zeros are chicory, rooibos, turmeric and herbal blends with no coffee, tea or cacao in them.

How much caffeine is in decaf mushroom coffee?

About 2 mg in an 8 oz cup by USDA's table for brewed decaf, which is 1 mg per 100 g. A laboratory that measured ten decaffeinated coffees from different outlets found 0 to 13.9 mg per 16 oz serving, so a large decaf can reach the low teens. Regular brewed coffee is about 95 mg a cup.

Does RYZE make a decaf mushroom coffee?

No. RYZE's coffee is 48 mg of caffeine a serving. Its caffeine-free product is Mushroom Chicory, an instant chicory blend with mushrooms and MCT printed at zero caffeine, which is not coffee.

Does Four Sigmatic have a decaf?

Yes, two: Calm Decaf Ground Coffee with reishi and chaga, $20 for 13 servings, and Focus Decaf Coffee Pods with lion's mane, $36 for 24. Both use the Swiss Water Process. Its Mushroom Blends, Elixirs and Calm Cacao are sold caffeine-free.

Is decaf mushroom coffee good for you?

The coffee part keeps most of the long-term associations seen for coffee: in a meta-analysis of 28 cohorts each daily cup of decaf went with a 6% lower risk of type 2 diabetes against 9% for caffeinated, and in the UK Biobank decaf drinkers showed the same inverse association with mortality as other coffee drinkers. The mushroom part depends on the dose, and the decafs we found print little or none of it.

Can I drink decaf mushroom coffee at night?

On the caffeine, yes: 2 to 14 mg is far below the 107 mg cup that a meta-analysis says should be 8.8 hours before bed. The mushrooms in the decafs (reishi, chaga, lion's mane, cordyceps, maitake) carry no caffeine, and none of them has a trial showing it disturbs sleep at these amounts.

Is Swiss Water decaf chemical-free, and does it mean no caffeine?

It is a water and activated-charcoal process with no solvent, so no methylene chloride or ethyl acetate is involved. It does not mean zero caffeine: a Swiss Water decaf carries the same few milligrams as other decafs. "Chemical-free" describes the process, not the residue.

Is Alphacino decaf?

No. Alphacino is a caffeinated robusta at 100 mg a scoop with 100 mg of L-theanine, built for the morning lift without the jitters. If you need to avoid caffeine, choose a decaf or a true zero from this guide instead.
