Mushroom coffee for coffee drinkers
If you have tried mushroom coffee before, you have probably tried an instant sachet. Stir a brown powder into hot water, accept that it tastes like a compromise, and move on. Grym is built for the opposite kind of person: the one who already owns a grinder, who knows the difference between an aeropress and a cafetiere, and who is not willing to give up a good cup to get the mushrooms in.
Grym is real, specialty-grade ground coffee, pre-blended with organic lion’s mane and reishi extract before it ever reaches your kitchen. You brew it exactly the way you already brew coffee. The mushrooms come along for the ride, properly measured into every scoop.

- Format: 250g ground coffee
- Extract: min 750mg per serving
- Mushrooms: organic lion’s mane + reishi, dual extracted
- Brew: aeropress, cafetiere, pour-over
- Not instant
Properly dosed mushroom coffee, not a token sprinkle
The dirty secret of the category is the dose. Many products list a mushroom on the front of the pack and then include a few milligrams of it, far below the amount studied in any research. Grym is built around the dose first. Every serving carries a minimum of 750mg of dual-extracted mushroom, so the lion’s mane and reishi on the label are the lion’s mane and reishi in your cup.
Dual extraction matters because the useful compounds in these mushrooms do not all dissolve the same way. We explain the method, and the reasoning behind the 750mg figure, on the science page.
The two mushrooms in Grym
Lion’s mane
Hericium erinaceus. A culinary mushroom traditionally used in East Asia, now studied for its compounds called hericenones and erinacines. Read more on the lion’s mane page.
Reishi
Ganoderma lingzhi. Known for centuries in traditional practice and researched for its triterpenes and beta-glucans. Read more on the reishi page.
How to brew Grym
Grym is ground for everyday filter and immersion brewing. Use it like any good coffee: roughly one heaped scoop per cup, adjusted to your taste. Stir well, because the mushroom extract is finer than the coffee grounds and likes to settle.
Aeropress
Standard recipe, medium grind. Stir for ten seconds before you plunge to keep the extract evenly suspended.
Cafetiere
Four minute steep, then press slowly. The mesh holds the grounds back and lets the extract through.
Pour-over
V60 or similar. Bloom for thirty seconds, then pour in slow circles. A clean, bright cup with the mushrooms carried through.
