Four Sigmatic Organic Mushroom High Caffeine Coffee

Want to switch to mushroom coffee without giving up on your caffeine intake? Then you need a really strong product, like this one by Four Sigmatic.

There are 3 key energetic ingredients: L-theanine, cordyceps mushroom, and, you guessed it, caffeine.

L-theanine is an amino acid that, when paired with caffeine, helps increase focus and attention. At the same time, it helps you relax and relieve stress. And because of this ingredient, you won’t get the jitters from too much caffeine.

Cordyceps, aside from the energy kick, is added to boost the immunity system.

For this product, the brand uses single-origin coffee grown at 5,500 feet above sea level in Honduras. Roasted dark, it creates a full-bodied cup with notes of chocolate and nuts.

As for the caffeine content, a 6-ounce cup contains about 80 milligrams, which is roughly the same as a shot of espresso.

The grind size of this mushroom coffee is medium-fine, suitable for Moka pots and pour-overs. The brand claims you can use it for a cold brew as well, but that will probably give you too bitter results. It’s also not suitable for methods that require a finer grind, like espresso or Aeropress.


  • Single-origin coffee ensures a delicate flavor profile.
  • L-theanine prevents jitters from high caffeine content.
  • Caffeine paired with L-theanine gives a nice energy boost.
  • Climate pledge friendly and USDA organic certified, meaning it’s made under rigorous standards.


  • The ground size makes it only suitable for two brewing methods.
