From the roaster

  • SMOOTH AND NUTRIENT-DENSE ORGANIC COLD BREW COFFEE INFUSED WITH SUPERFOODS — Enjoy a delicious and full-bodied cold coffee without the bitter aftertaste, infused with some of the world's most nutrient-dense ingredients. Our unique blend of superfoods, including immunity-boosting and attention-amplifying Lion's Mane mushroom & Yacon Powder, creates an astoundingly effective and flavorful beverage.
  • THE BENEFITS OF COMBINING LION'S MANE MUSHROOM WITH COLD BREW COFFEE — Experience a refreshing twist on your coffee routine with our coffee grounds for iced coffee enriched with 250mg of organic Lion's Mane per serving. Lion's Mane, a functional nootropic mushroom, has been used for centuries worldwide to enhance focus and creativity. When combined with our delicious organic dark roast coffee, it provides a smooth and crash-free source of energy and concentration for hours, without any jitters.
  • A DIGESTION-FRIENDLY BLEND — With organic Yacon root, a prebiotic adaptogen, this coffee nurtures your gut while delivering a rich and satisfying cup. Digestive wellness never tasted so good
  • HOW TO (COLD) BREW — For a smooth and flavorful cold brew, we recommend using 2 tablespoons of our premium coarse coffee grounds for every 8 fl. oz. of water. The beans used for our better-for-you cold brew coffee grounds are ethically sourced from a family-run co-op located 5,500 feet above sea level in southwest Honduras, ensuring the highest quality and sustainability.
  • 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.

    Great coffee, will definitely purchase again!

    Tastes great and gives me a nice boost in the morning without the jitters. I’ve made it the suggested way for cold brew and used the same measurements with my single serve kcup machine for hot and turned out good both ways!

    Excellent Taste

    This is wonderful coffee. I am amazed and addicted. I try others, but am not happy until I have my own coffee, this coffee. I am so glad I bought some in Stanton, VA, at a health food store to try. Just a blessing.

    Good enough for a homemade cold brew

    For a homemade cold brew, this does it for me. It has a little odd taste to it compared to a true coffee cold brew, but that’s expected as this contains mushrooms. It’s easy to make, you just have to plan a day ahead since you have to pre-soak the grounds a day before you plan to drink it.
