How is Holy Joe's 48-hour cold-drip coffee made?

Holy Joe is produced through a 24-48 hour cold-drip extraction. This process minimizes acidic compounds like quinic and caffeic acids, resulting in a low-acid coffee that is gentler on the human digestive tract according to Specialty Coffee Association (SCA) standards.

Are there human studies on Shiitake and Maitake mushrooms?

Yes. A study in the Journal of the American College of Nutrition (2015) showed Shiitake (Lentinula edodes) improves human immune markers. Research in the Journal of Medicinal Food (2002) highlights Maitake's (Grifola frondosa) SX-fraction in supporting metabolic health.

Is Holy Joe coffee tested for mycotoxins and heavy metals?

Every batch is verified mould and mycotoxin-free. Our Australian mushroom extracts are independently lab-tested for heavy metals and chemical residues to ensure the highest purity standards for functional beverages.

What is the shelf life of Holy Joe mushroom coffee?

Unopened bottles are shelf-stable for up to 6 months when refrigerated. Once opened, the cold-drip concentrate should be consumed within 14 days for optimal flavor and potency.

FAQs

1. Product & Process

Q: What is cold-drip coffee and how is it made?

A: Cold-drip coffee is a premium brewing method that involves slowly dripping cold, filtered water through specialty ground coffee beans over a 24-48-hour period using a custom-built drip tower. Unlike hot brewing, this slow-extraction process ensures every molecule of flavor is captured, resulting in a smooth, low-acid ready-to-drink coffee with a signature bold aroma and a clean finish.

Q: Is Holy Joe Coffee organic?

A: While Holy Joe is not yet certified organic as a brand, we prioritise the highest quality ingredients. We exclusively use certified organic, mould and mycotoxin-tested coffee beans, and our Australian mushrooms are independently tested for contaminants such as chemical residue and heavy metals. This ensures your daily brew is free from any synthetic or harmful substances.

Q: Does Holy Joe contain any sugar, additives, or preservatives?

A: We believe in total transparency and clean energy. A bottle of Holy Joe contains zero added sugar, no artificial flavors, and only naturally derived organic preservatives. Our only ingredients are sustainably sourced organic coffee beans, natural spring water, Australian-grown mushroom extracts and a naturally fermented preservative that’s also derived from mushrooms.

2. Health & Dietary

Q: What is the scientific basis for including Shiitake and Maitake extracts?

A: We make no direct claims of health benefits from drinking Holy Joe.

We have however attached two peer-reviewed studies below regarding both species of mushrooms.

Shiitake (Lentinula edodes): In a 4-week dietary intervention study involving healthy young adults, daily consumption of Shiitake resulted in improved human immunity markers, specifically increasing the proliferation and activation of T-cells and reducing inflammatory proteins (Journal of the American College of Nutrition).
Maitake (Grifola frondosa): Known in Japan as the "Dancing Mushroom," Maitake has been the subject of human research regarding its D-Fraction (beta-glucans). Research from the University of Louisville indicates that Maitake extracts can assist in modulating the human immune response and supporting healthy metabolic markers.

Q: Is Holy Joe coffee vegan and keto-friendly?

A: Yes! Holy Joe is 100% plant-based, vegan-friendly, and gluten-free. Because we don't add any sugars or fillers, it is also a perfect choice for those on a Keto or Paleo diet looking for a clean, functional caffeine boost.

Q: Does your coffee contain caffeine?

A: Our Original Holy Joe brew contains naturally occurring caffeine for a sustained energy boost.

Q: How does cold-drip extraction affect human digestion compared to hot coffee?

A: The primary difference lies in the chemical acidity and gastric tolerance. When coffee grounds are exposed to high heat, certain chlorogenic acids break down into quinic and caffeic acids, which are associated with "acid stomach."

Cold-drip coffee has a significantly lower concentration of these acidic compounds. For many individuals, this results in a brew that is better tolerated by the digestive system, as it minimises the trigger for gastric acid secretion typically seen with hot-brewed alternatives.

3. Usage & Storage

Q: How long does Holy Joe stay fresh?

A: To maintain the best flavor, keep your Holy Joe refrigerated. Unopened bottles will stay fresh for up to six months. Once opened, we recommend enjoying your cold-drip coffee within 14 days to experience the best flavour.

Q: How do I serve Holy Joe cold-drip coffee?

A: Holy Joe is ready to drink - straight out of the bottle! Simply shake and serve! We recommend pouring it over ice, mixing it with milk/mylk, or heating it for an exceptionally smooth black coffee.

Q: What is the recommended serving size?

A: Each 700ml bottle of Holy Joe provides fourteen 50ml servings. Because our coffee packs a punch, a little goes a long way in providing your daily dose of caffeine and mushrooms..
