Our Verdict
Defiant Coffee delivers a clean, simple mushroom coffee with strong sourcing claims: US-grown organic fruiting body mushrooms, fair trade single-origin coffee, and zero fillers. The formula is minimal (just coffee + 3 mushroom extracts), which is refreshing in a category full of kitchen-sink formulas. Main gaps are undisclosed mushroom amounts and no public testing data.
