Key Benefits
- Enjoy a rich, full-bodied cup—Swiss Water® process keeps the taste pure and aromatic.
- Smooth, mellow notes of nuts and brown sugar in every sip.
- Features real mushroom extracts—no mycelium or grains, just the good stuff.
Pause and savour a cup of Calm Organic Decaf Coffee from Four Sigmatic, thoughtfully blended with organic Reishi and Chaga mushrooms. This is your invitation to unwind—without the caffeine.
The organic Reishi mushrooms are grown on logs, while Chaga is wild-harvested from birch trees, bringing you authentic, carefully sourced botanicals. Four Sigmatic uses only real mushroom extracts, never mycelium or grains, for a truly pure blend.
The fair-trade coffee beans are sourced from small Peruvian farms in the Cajamarca province, grown at high altitudes for exceptional quality. The Swiss Water® Process gently removes caffeine, preserving the coffee’s natural depth and aroma.
Ready to brew your way, this organic decaf coffee delivers a smooth, satisfying cup—perfect for any time you want to take it slow.
Four Sigmatic, founded by Tero Isokauppila, brings the benefits of Nordic foraging traditions to your daily routine. Drawing inspiration from the Finnish countryside, where mushrooms and adaptogens thrive, the brand blends these powerful ingredients into coffees, elixirs, and more. Four Sigmatic’s mission is to support both mental and physical wellbeing by offering natural, functional solutions. Every product is crafted with care, using only the finest mushrooms and herbs, ensuring that each cup helps you feel your best, while remaining rooted in the brand’s commitment to quality and sustainability.
