What Sets Us Apart

[H2]
A Higher standard for functional Mushrooms
For over a decade, we’ve been obsessed with doing mushrooms right — from how they’re grown and tested to how they taste in your cup.

[H3] Legacy and Expertise

[H5] Rooted in Mushroom Tradition
Founded in 2012 by a 13th-generation farmer, our work began long before mushrooms were trending. We’ve spent years studying, sourcing, and perfecting functional mushrooms to unlock real benefits — not hype.

[H3] Quality and Testing

[H5] Only the Essentials. Nothing Extra.
We use concentrated mushroom fruiting body extracts — never cheap mycelium fillers. Every product is third-party tested for purity, potency, and toxins, and made with organic ingredients you can trust.

[H3] Taste and Experience

[H5] Functional, Finally Delicious
Great benefits shouldn’t come with a tradeoff. Our products are crafted to taste smooth, rich, and familiar — so adding mushrooms to your daily routine feels effortless, not medicinal.

Frequently Asked Questions

What is the main ingredient in this product?

The main ingredient is organic instant coffee with a sidekick of lion’s mane and chaga mushroom. No, this product does not taste like mushrooms!

Does this product contain any sweeteners?

It does! We use organic coconut palm sugar and organic stevia extract for the lightly sweet flavor with only 1 gram of sugar. (Not stevia’s biggest fan? Ours doesn't have the metallic aftertaste that others do).

How do I prepare this Think Organic Coffee?

Stir with hot water and enjoy!

Can I mix with other products of yours?

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.

What is the recommend storage instructions?

A dry and cool space, somewhere the coffee won’t get burnt by the sun!

What are the main benefits associated with this product?

Mental focus, productivity, concentration and energy! (And who doesn’t need more of that).

Focus

[IMG: Organic lion’s mane extract]

Organic lion’s mane extract

This mushroom takes after its name with a fierce brain-powering boost to keep you sharp and energized. We extract our lion’s mane from log-grown fruiting bodies: fully organic, with no fillers, grains or carriers.

Focus

[IMG: Organic wildcrafted chaga extract]

Organic wildcrafted chaga extract

Meet your ultimate immune system supporter. Packed with antioxidants, this mushroom helps keep your body well. Our chaga’s sustainably wildcrafted on birch trees, just as nature intended. We extract the real chaga (no mycelium, fillers or grains here) to unlock the best of the best benefits.

Immune Support

[IMG: Organic lucuma powder]

Organic lucuma powder

This superfood has a naturally sweet taste without any grams of sugar. More than just a sweet taste, lucuma is packed with a bounty of vitamins and minerals.

Natural Sweetener

[IMG: Organic mucuna extract]

Organic mucuna extract

Mucuna is an adaptogenic herb used traditionally in Ayurvedic medicine. It complements the power of caffeine because it contains L-dopa, the precursor to dopamine.

Mood Support

[IMG: Organic coconut palm sugar and organic stevia]

Organic coconut palm sugar and organic stevia

Just the right amount of sweetness to pair with smooth matcha mixture. We use organic coconut palm sugar and organic stevia extract for the lightly sweet flavor with only 1 gram of sugar. (Not stevia’s biggest fan? Ours doesn't have the metallic aftertaste that others do).
