Wild Chaga — Chunks & Granules

(Inonotus obliquus)

Wild Local Harvest | Pennsylvania Forests | Winter-Harvested

100% local, wild chaga — hand-foraged from Pennsylvania hardwood forests, never cultivated. Chaga is one of our favorite fungi to work with medicinally — technically not a mushroom, but a sclerotium (a hardened mass of mycelium the fungus builds up over years inside its host tree).

We harvest exclusively in winter, following traditional Native American practice, when the fungus's potency is said to be at its peak.

Chaga has long been used as a clean alternative to caffeine — steady, sustained energy without the crash. Many of us on the team drink chaga tea blended with cacao powder and other herbs and spices as a full caffeine replacement: no jitters, no afternoon crash, no anxiety, no irritability — just steady, clean energy alongside its mineral and antioxidant content, and its traditional use in supporting cardiovascular health.

Ingredients: Wild chaga (Inonotus obliquus) — dried, whole chunks or ground to approximately 50 mesh.

What Is Chaga?

Chaga is a fungus that primarily parasitizes birch, as well as other hardwood trees. Technically not a mushroom but a sclerotium — a hardened mass of mycelia the tree forms in response to the fungus. It grows in cold climates across Northern Europe, Asia, Siberia, Russia, Northern Canada, Korea, and North America.¹⁰

History of Use

Chaga has been used by humans for a very long time. It's rumored to have been carried by Ötzi the Iceman for use in transporting fire embers, and has a documented history of use by the Khanty people of West Siberia.¹¹ In Chinese medicine, it's referred to as the "King of Herbs."

Chunks vs. Granules

Both forms come from the same wild-foraged, winter-harvested material and carry identical potency. Chunks are left whole for those who want to break, chip, or simmer their own decoction. Granules are ground down to approximately 50 mesh for faster steeping and easier extraction — the finer particle size means more surface area exposed to water or your solvent of choice, so granules carry a modest premium to reflect the extra processing step.

We intentionally stop at 50 mesh and never grind chaga down to a fine powder — a true powder is a nightmare to filter out of tea or a tincture, leaving you with gritty sediment in every cup or bottle. 50 mesh gives you the extraction benefits of a finer grind while still straining out clean.

How to Use

Chaga Tea (Traditional Decoction)

Chunks are best suited for a slow decoction; granules work well for a quicker daily steep.

Chunks: Add 1–2 tbsp of chaga chunks per quart of water. Bring to a gentle simmer (never a hard boil) and let steep for 1–4 hours — the longer the simmer, the deeper the extraction. Strain and enjoy hot. Reserved chunks can be re-simmered 2–3 more times before they're spent.
Granules: Steep 1–2 tsp per cup in hot (not boiling) water for 10–15 minutes, or run through a French press for a smoother cup. Great for a quick daily brew or blending with cacao and spices.
Store brewed tea in the fridge for up to a week.

Chaga Tincture (Dual Extraction)

Chaga's beneficial compounds are split between water-soluble and alcohol-soluble fractions, so a traditional dual extraction pulls both:

Coarsely chop chunks or use granules, and pack loosely into a clean glass jar.
Cover completely with high-proof alcohol (vodka or grain alcohol, roughly 80–100 proof). Seal and macerate for 4–6 weeks in a cool, dark place, shaking every few days.
Strain and reserve the alcohol extract. Simmer the strained-out chaga (the "marc") in water for 2–4 hours to draw out the water-soluble compounds.
Strain the water decoction and combine it with the reserved alcohol extract.
Bottle in dark glass. Properly made, a dual-extract tincture keeps for several years stored in a cool, dark place.
