Flavor Profile

Expect a robust, balanced coffee with hints of rich cocoa and brown sugar. The Honduran beans give it a smooth, mellow flavor with low acidity and subdued bitterness. The lion’s mane and chaga mushrooms blend subtly into the finish without any medicinal or earthy taste.

Ingredients Analysis

The single-origin Honduran coffee beans are shade grown and dark roasted to develop the complex, aromatic flavor. The organic mushrooms provide immune-supporting compounds like beta-glucans and antioxidants without altering the coffee’s taste. The vegan pods contain no artificial flavors or preservatives.

Health Impact

With 140mg of caffeine per K-Cup, it provides a moderate caffeine jolt. Consuming 2-3 cups daily should be safe for healthy adults but may cause jitters in sensitive individuals. The dual mushrooms provide additional brain, nerve and immune benefits.


The pods offer mess-free brewing and easy disposal compared to ground coffee. They lock easily into your brewer and cleaning is a breeze. The pods are only available online but ship quickly in recyclable packaging.


The sleek black boxes showcase the brand’s minimalist style. The lightweight cardboard makes storage easy and has minimal environmental impact. Each 24-count box contains a month’s supply of mushroom coffee pods.

Pod Material

The pods appear to use plastic but the exact composition is unknown. While not biodegradable, they are recyclable which lessens environmental impact. Using reusable filters would be an even more eco-friendly option.


The pods are BPA-free and contain no toxic materials, making them safe for use in brewers. The organic coffee and mushrooms pose no health risks at suggested serving sizes. The hot coffee requires caution as you would exercise with any heated beverage.


While plastic pods generate some waste, they are recyclable in most municipal programs. The organic, non-GMO ingredients and responsible coffee sourcing makes this a more eco-conscious choice. Using a reusable pod system would further reduce waste.

Brand & Options

Four Sigmatic is a reputable company with over a decade perfecting mushroom coffee and other functional foods. They offer a few additional mushroom coffee flavors tailored to different needs. All pods consistently provide high quality.

Shelf Life & Origin

The pods are freshness sealed to retain flavor but the exact shelf life is unspecified. The single-origin Honduran coffee comes from family farms in Marcala. Four Sigmatic roasts the beans in-house and infuses with mushrooms under strict quality control.
