The BEST Mushroom Coffee that I have tried! LOVE! - A Coffee Lover/Avid Coffee Drinker
AMAZING flavor in a French press! Follow the instructions, the scoop amounts are correct. The bag tells ya. Phenomenal coffee, that actually tastes good and has benefits that you can FEEL. Focus is real. The High Caf is superb too and is definitely HIGH caffeine - dark and rich and beautifully unbitter. Same with this one, rich and bold and smooth. A favorite here.

Good, smoothe, coffee
Really like this coffee! It tastes like good regular coffee (no mushroom taste at all). When I brewed it my husband didn't even notice it was mushroom coffee, but did notice it didnt have the sweet vanilla flavor the other coffee he likes does. But the health benefits are good and the coffee is smoothe, the only wish I have is that it was higher caffeine. I saw 250mg in listed in the specifications for caffine, but apparently this is not their high caffeine coffee so that confused me. Apparently this one only has 150 mg. I am trying their high caffeine coffee next though!

Good, but pricey
I like what Four Sigmatic is doing here. This review is for the variety I ordered - Think (with Lion’s Mane). To be quite honest, I stumbled across this product while looking for lower priced alternatives to Mudwtr. I’d seen a few ads for Mudwtr and wanted to check it out. Until I saw the price, that is. Mudwtr is a little over $7 an ounce (!), while the Four Sigmatic blend is a little over $1 an ounce. A pretty significant price difference, I’d say. I have not tried Mudwtr because of the excessive price. I like the idea of it and support what they are doing, but I am a heavy coffee drinker. I have worked swing shift for over 27 years and have given up soda and sweetened beverages. However, I drink a lot of coffee. It doesn’t seem to affect my sleep much, and I have way less adverse effects from caffeine than sugar, but… I know that caffeine is not good for anyone in large amounts and that we should all cut back or eliminate it from our diets. I’ve been on a kick where I’m trying to eat and drink healthier to try to avoid more health problems as I age. So back to the coffee. Cutting back hasn’t worked too well because I need something to stay awake all hours of the day and night, and most of the caffeine alternatives are worse for me than drinking coffee. Mudwtr sounds like a great idea because it is supposed to look like coffee and taste good but only have mushrooms and adaptogens in it - an energy booster without the coffee and caffeine and all of the associated side effects. But it runs about $2 a cup - a little too expensive for me to sustain in the long term. I love the idea of it, but I’d have to cut down to one cup every day or two. The Four Sigmatic coffee is much more affordable. It comes out to less than 30 cents per cup. It also claims to give you the energy boosting and sharp focus effects of coffee without the adverse side effects. However, it has coffee blended with mushrooms (or is it the other way around?) instead of a non coffee blend. I found it to be pretty much as advertised. It looks and tastes like regular coffee. As mentioned earlier, I tried the Lion’s Mane blend, and it was excellent. Wouldn’t know it had mushrooms in it from the taste - just a regular medium dark roast. The claims of all the benefits with no drawbacks seems to be valid as well. But… … you can get a really good bag of coffee for $1 an ounce. I usually drink Folger’s Classic Roast, and I can get a 3 pound can of that for $11. That works out to about 23 cents per ounce which works out to 6-7 cents per cup, depending on how strong I make it. I know money isn’t everything, but it does seem to make the world go round, and I never seem to have as much as I’d like. So, as much as I’d like to make this coffee my daily driver, I don’t think I’ll be able to because of the price. For now it is my “day off” or “special occasion” coffee. There may be a day when I can switch to drinking it full time without cutting corners somewhere else (like buying less produce for example). Five stars for the product, I’m deducting one for the price. That’s just for me, though. I’d say if you can afford it, go for it, or try the Mudwtr even. I’m going to continue to swap this out with the Folgers and try to get the bag to last a while. Then, I’m going to try the Laird Superfood coffee which is similar to this one but a bit cheaper.

The Truth About This Mushroom Coffee…
I've been a fan of Mushroom Coffee for 8 years now and have tried almost everything out there. I have learned 4 very important things to look out for when choosing the best mushroom coffee: 1. Taste 2. Dosage 3. Quality 4. Value Here’s the breakdown of my thoughts on Four Sigmatic Ground Coffee: 1) TASTE: Overall taste is excellent - the beans are roasted nicely, and the flavor is smooth with a hint of chocolate notes, so I’m very happy with the taste. 2) DOSAGE: This part is extremely important, because if you’re going to incorporate functional mushrooms into your routine you need to know how much of each mushroom you are putting in your body and this can be the hardest information to derive from many brands. In doing my own research I’ve found that you want at least 500mg of one strain to see any benefits. Four Sigmatic only uses 2 mushrooms, Lion’s Mane and Chaga. However, the dosage amount is not stated anywhere on the packaging, and because it’s just coffee beans, I can’t even begin to guess. It could be fractions of what a normal dose should be. 3) QUALITY: Four Sigmatic uses 100% fruiting bodies, which is the purest form of mushroom extract and what I look for in my mushroom coffee. 4) VALUE: The quality seems good, but there is no clear statement on the dosage of mushroom extract per serving which makes the value very low for me. Right now, I use Lucid as my main morning routine coffee and Four Sigmatic on my downtime as maintenance. Four sigmatic makes me feel good, however I feel much more effects with Lucid because 1) It delivers a much higher dose of 4 mushrooms at 2,000mg total 2) It has a nootropic stack (fuel for your brain) 3) It uses 100% fruiting body mushroom extract (the highest quality possible). Plus, it tastes great. Four sigmatic will stay in my rotation for chill days because it’s cheap, but I turn to Lucid when I need to operate at peak performance. Remember to keep these tips in mind and always read the label!

Consistent favorite — tastes like real coffee and easy to drink daily
I’ve purchased Four Sigmatic Focus Mushroom Coffee many times over the years, and it has become a regular part of my routine. If you’re worried about mushroom coffee tasting “earthy” or strange, this one really doesn’t — it tastes like normal coffee to me. The flavor is smooth and familiar, especially when prepared the same way I make regular coffee. I usually drink it plain or with a little cream, and it blends well without any gritty texture. One of the main reasons I keep repurchasing this is how it fits into my day when I need to stay focused. For me, it provides a steady, clear alertness that helps when I’m studying or working. I also appreciate how it feels gentler on my stomach than some stronger coffees — no jittery spikes or crashes as I’ve experienced with other blends. I’ve enjoyed how the mushroom blend seems to offer a balanced energy experience that works well as part of my morning or afternoon routine. It’s become something I reach for when I want a cup that helps with focus and feels supportive overall. What I appreciate most is the consistency. Every time I reorder it, the taste and quality are the same, which is why I’ve continued buying it. It’s also convenient to make, especially on busy days. This won’t be for everyone, especially if you’re very particular about specialty coffee flavors, but if you want something that still tastes like coffee and supports your focus and overall feel‑good routine, this has been a solid choice for me. I’ll continue repurchasing it.
