Frequently Asked Questions

The main ingredient is coffee with a sidekick of lion’s mane and chaga mushroom. No, this product does not taste like mushrooms!
Nope! If you like sweetener in your coffee try our Think Organic Creamer!
If you love hot coffee, mix 4 Tbsp coffee with 12 fl. oz. hot water in a drip coffee maker, French press, or pour over. Elevate your coffee with our Think Organic Creamer! Prefer it iced? Pour over A LOT of ice. Or make a cold brew by adding cold water to the grounds and then letting it steep for 24-48 hrs. (We actually made a version with coarse grind just for that! Check out Think Organic Cold Brew Coffee).
Mental focus, productivity, concentration and energy! (And who doesn’t need more of that).
You absolutely can! Our favorite is our Focus Blend + Think Organic Creamer (no caffeine but help you stay focused all day)! We’ve even added it with Organic Plant-based Protein in a caffeinated smoothie.
Right away you should feel focused and more productive. After a few weeks you’ll start to notice that you are less likely to feel run down, or foggy. Functional mushrooms are safe to consume long-term and you’ll notice how much better you feel now if you try a cup of regular coffee after a month of your Think Ground Coffee.
About 150 mg per 12 oz cup, about the same as regular dark roast coffee.
No! We proudly use USDA organic dark roast Honduran coffee in this coffee.
A dry and cool space, somewhere the coffee won’t get burnt by the sun!
