The Coffee Score review

AN INNOVATION IN INSTANT — After carefully roasting and brewing the shade grown, organic, Colombian coffee beans, we concentrate the coffee by evaporation, and finish it off by spray-drying it into a pure, delectable, instant powder. Our team spent hands-on time with the Four Sigmatic Organic Instant Coffee Powder to see how it holds up against the rest of the instant coffee we've tested.

Across repeated sessions we evaluated it on the categories that matter most: quality, consistency, value, and how likely we are to reach for it again. Ranked #101 of our top 200 instant coffee — an outstanding medium pick, earning a 4.5★ average across 2,556 Amazon ratings.

From the roaster

  • AN INNOVATION IN INSTANT — After carefully roasting and brewing the shade grown, organic, Colombian coffee beans, we concentrate the coffee by evaporation, and finish it off by spray-drying it into a pure, delectable, instant powder. Our Finnish roots mean we take coffee very seriously, which is why we also 3rd party lab test each batch for the utmost quality, ensuring each serving will deliver 50mg of caffeine (about half of a regular cup of coffee).
  • HARVESTING THE ANCIENT ENERGY OF CORDYCEPS — Cordyceps were first discovered by sherpas of the Himalayan mountains. After trying these small, strange looking mushrooms, they could breathe easier at high altitudes, had a lift in physical energy, and had greater endurance. Today, Cordyceps militaris is used for the same benefits originally discovered by the sherpas, with loads of scientific research to validate the compounds responsible for its effects. Each cup contains 150mg of Cordyceps.
  • RISE AND REALLY, TRULY SHINE — Each cup contains 350mg of wild-harvested, organic Chaga. Known as The King of Mushrooms, Chaga got its title from its incredible immune-supporting effects. Chaga is absolutely loaded with antioxidants. In fact, it is one of the most antioxidant-dense foods on the entire planet.
  • AN INCOMPARABLE IMMUNE DEFENSE CONCOCTION — Modern life can wreak havoc on our immunity. Over-stressed. Sleep deprived. Not enough physical activity. All of these can lead to a weakened immune system. Our Defend instant coffee mix was designed for exactly this; a convenient, exceptionally effective, immune support supplement that fits into your busy morning routine.
  • SCIENTIFICALLY SPEAKING, THIS COFFEE IS PRETTY MUCH MAGIC — Functional mushrooms have been used around the world for centuries to improve productivity, immune support, and more. Unfortunately, the majority of the mushroom supplement market aren't mushrooms at all, but rather the mycelium (basically the root system). At Four Sigmatic, we bring only the best of nature to your daily routine, so we always use the mushrooms' fruiting bodies which contain 15x more active ingredients than the mycelium.

    LOVE Four Sigmatic Coffee over all other mushroom coffees!

    Update 4/26: the product itself still gets 5 stars but Amazon warehouse does not! I’ve tried to reorder twice and I keep getting sent the wrong one! Apparently there’s a mix up going on between “Gut Health” and “Protect.” I would like to order more Protect.My husband and I LOVE this coffee.

    It works

    When I first receive it. The box says chaga only. No cordyceps and chaga which I thought I bought. Got me worried, I thought I was ripped off lol but than I read the Ingredients it did have cordyceps. What a relief, I heard this stuff from Thomas DeLauer and Tim Ferriss. I was skeptical at first.

    Magic Mushroom Covfefe? Prolly Not...

    First of all, this is a Reviews with Booze item. Basically, we find/buy trending products from a major website that creates a lot of "Buzz" on your "Feed" and then we make a fresh cocktail and tell you what we think while we drink.
