Why we were able to achieve undetectable levels of mold toxins in our decaffeinated beans

Thank you as always!
This is Gokujo Mold-Free Coffee.

For some time, we have received numerous inquiries from customers asking, "Do you have decaffeinated coffee?" and "We want clean decaf that we can drink safely at night." We realize every day how much more health-conscious people are becoming, seeking gentle options for their bodies to accompany their work in the evenings.

In response to your expectations, a major project we had been working on behind the scenes has finally come to fruition. We submitted newly sourced decaffeinated (decaf or caffeine-free) green beans to a government-certified testing agency, and after rigorous component analysis, we were able to proudly prove the best possible result: [NO MOLD TOXINS DETECTED].

This time, I will explain why it is so difficult to eliminate mold toxins in decaffeinated coffee, why I have hesitated to sell it until now, and our commitment and the background of its distribution.

Why I have hesitated to sell decaffeinated coffee until now

Actually, despite receiving daily requests from customers asking, "Do you have decaffeinated coffee?", I have hesitated to offer "organic and decaffeinated" products until now.

This is because the combination of "organic x decaf" is the area where mold is most likely to occur in the coffee bean distribution process, making risk management extremely difficult.

Organic green beans are not permitted to use any chemical preservatives or fungicides (post-harvest pesticides) from cultivation to transportation and customs clearance. In other words, "chemicals to prevent mold" cannot be used.

Even this increases the risk of mold, but decaf beans also undergo a special process of "soaking in water to extract and remove caffeine" in their raw state before roasting.

Re-drying decaf beans, once thoroughly soaked in water, evenly to a moisture content suitable for transport (around 10-12 percent) requires extremely advanced technology and high costs. In the mass production market, this drying process and the subsequent management during several months of ocean shipping tend to be lax, and significant temperature changes when passing the equator can make them a breeding ground for harmful mold much more easily than regular beans.

"I want to deliver something gentle to the body, but I cannot give customers the risk of mold toxins instead of chemicals."

Until I could be absolutely certain that this high hurdle could be cleared, I could not easily proceed with commercializing the product.

Thorough Manual Work and the Fusion of Scientific Data

Vulnerability of Processed Green Coffee Beans: Green coffee beans that have undergone caffeine extraction treatment have the characteristic of easily absorbing surrounding moisture due to the relaxation of their cell walls. If strict temperature and humidity control is not maintained during distribution and storage, there is a risk of rapid proliferation of mold toxin-producing strains such as Ochratoxin A. (From risk assessment data of imported foods by the European Food Safety Authority (EFSA))

Precisely because of these high hurdles, we have eliminated all compromises from the raw material selection stage. We carefully selected beans processed safely without any chemicals, using only natural mountain water to remove caffeine. Furthermore, we conducted thorough hand-picking by skilled artisans to eliminate defective beans that pose a mold risk to the absolute maximum.

Finally, we submitted the batch to a strict government-certified inspection agency and received scientific proof of "no mold toxins detected."

Summary: Forget Unnecessary Noise and Enjoy a Truly Relaxing Night

For health-conscious individuals who avoid the "four poisons" (wheat, vegetable oils, dairy products, and sweets) to suppress chronic inflammation in their bodies, and for those with naturally delicate digestive systems, trace amounts of mold toxins and pesticide residues in decaf can be a significant "noise" that disrupts their physical condition.

The decaffeinated coffee we have perfected this time is an exceptionally clean cup, having thoroughly "subtracted" such unnecessary risks.

To everyone who has been waiting for "caffeine-free?" we can finally deliver it with confidence. You can enjoy it with complete peace of mind, without worrying about indigestion or headaches, not only for refreshing yourself during the day when you want to reduce caffeine stimulation, but also during moments before bed when you want to maximize sleep quality.

We will announce the specific sales start date soon via our official LINE account and newsletter.

Please look forward to experiencing the sensation of only the deep sweetness and rich body inherent in the beans gently permeating your body, completely free from the "noise" of mold toxins.
