    great coffee !!

    i love this coffee ! ive been drinking the ground coffee for over a yr. i love the benefits. mental clarity. easy on the gut. the taste isnt bitter like reg. coffee. not acidic at all. very smooth. does not taste like mushrooms at all. i bought the Kcups bc they were a little cheaper than the ground coffee.

    Tastes like coffee!! It's golden!!

    I had to switch from regular coffee to tea bc of diverticulitis. But tea just doesn't have the same effect that coffee does for me. Trust you me!A coworker of mine heard me whining about having to drink tea, and she told me about Four Sigmatic organic mushroom coffee.

    So good and too pricey

    Love this coffee. Great taste. Very pricey and I hope as their popularity goes up the price will come down. I would like to be able to have this be my everyday coffee instead of a treat.

    Taste good!

    My boyfriend has been wanting to try this mushroom coffee for awhile so I ordered it for him. (This has been a re purchase like 3 times now haha!) It’s really good coffee, it doesn’t taste like mushrooms ( i thought for some reason it would so I was worried to try) NOPE! Taste like regular coffee. I recommend!
