Frequently Asked Questions
Gribb Mushexpresso is a certified-organic ground mushroom coffee combining 50% premium organic Arabica with four functional mushrooms: Reishi — Ganoderma lucidum (12.5%), Lion's Mane — Hericium erinaceus (12.5%), Chaga — Inonotus obliquus (12.5%), and Shiitake — Lentinula edodes (12.5%).
All mushrooms are whole fruiting body, grown in-house on Gribb's certified-organic farm in Portugal under PT-BIO-10. Because mushroom powder contains no caffeine, the 50/50 blend delivers approximately half the caffeine of regular coffee. Universal grind — compatible with espresso machines, drip machines, and French press.
Serving size: approximately 7g per cup. Contains 250g — approx. 30 servings. Contains coffee (caffeine). Packed in a facility handling nuts, peanuts, sesame seeds, gluten, and soy. May contain traces of nuts and sesame.
Yes. The 50% Arabica base is a premium universal grind selected for its full-bodied flavour profile — the mushrooms add a subtle earthy depth that most people describe as making the coffee taste richer and more complex, not strange. If you're used to good Arabica, you'll notice the difference from a regular cup, but you'll like it. Most people who try Mushexpresso go back to it rather than back to their old coffee.
Because mushrooms contain zero caffeine, and the blend is precisely 50/50 Arabica and mushroom extract. The Arabica contributes all the caffeine; the mushrooms displace half the Arabica that would normally be in the cup. This means a cup of Mushexpresso brewed at the standard 7g dose contains roughly half the caffeine of the same volume of straight Arabica. You still feel the caffeine — you just feel it at a level that doesn't spike cortisol and crash your afternoon.
Reishi's triterpenoids modulate the hypothalamic-pituitary-adrenal (HPA) axis — the same system that caffeine activates by triggering cortisol release. This makes them a genuine functional pairing: caffeine provides the alertness signal, Reishi moderates the cortisol spike that follows. The result is energy that feels steadier and more balanced, rather than the wired-then-crashed pattern that large caffeine doses produce. It's not just half the caffeine — it's caffeine delivered into an adaptogenically supported nervous system.
Universal grind — designed to work in espresso machines, drip coffee makers, and French press. Use approximately 7g per cup and adjust to taste. Stronger brews will extract more of the mushroom compounds alongside the coffee. It does not work in capsule-only machines (like original Nespresso), but works in any machine that uses loose ground coffee.
Because Lion's Mane's hericenones support nerve growth factor — the compound that maintains the neural pathways for focus, memory, and cognitive clarity. Caffeine opens your eyes and wakes you up; Lion's Mane helps maintain the neural substrate that makes sustained focus possible. Coffee that wakes you up and supports your cognitive hardware at the same time. That's the combination most coffee brands can't offer.
Absolutely — works exactly like regular ground coffee in any espresso-based drink. Pull a double shot, add oat milk, and the mushroom compounds come through the extraction exactly as they would in black coffee. The earthy notes of Reishi and Chaga actually complement milk-based drinks particularly well.
