Frequently Asked Questions
MushExpresso is Gribb’s organic ground mushroom coffee, made with 50% Arabica coffee and 50% Reishi, Lion’s Mane, Chaga and Shiitake.
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.
Both contain 50% Arabica and 50% mushrooms. MushExpresso is ground coffee for brewing in an espresso machine, filter or French press. Mushcoffee is instant and dissolves directly in water or milk.
Arabica remains the dominant coffee character, while the mushrooms add a subtle earthy depth.
The 50:50 formula contains less coffee by weight than an equivalent amount of pure ground coffee because half of the blend is mushroom. Actual caffeine in a brewed cup can also vary according to coffee dose, brewing method and extraction.
Yes. It has a universal grind suitable for espresso machines, filter/drip coffee and French press.
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.
