"I ordered coffee beans, and there's oil seeping out. Is that okay?" We sometimes receive this question from customers.

Some health-conscious individuals might worry, "Won't the oil upset my stomach?" But to put it simply, fresh coffee oil itself is perfectly fine.

To conclude, the oil floating on the surface of coffee beans is by no means a bad thing! On the contrary, it's a vital natural nutrient and flavor component that creates coffee's inherent rich aroma and deep body.

Especially at our store, to ensure the best possible condition, we are committed to shipping "within 24 hours of roasting." The fresher the beans immediately after roasting, the more their natural oils are pushed to the surface along with internal gases. Therefore, the oil seeping from the beans is precisely a sign of being freshly roasted and fresh.

This time, we will explain in detail the effect of coffee oil on taste and the real cause of an upset stomach.

[What is Coffee Oil? Its Appeal and Characteristics that Change with Brewing Methods]

Coffee oil is a natural lipid component originally contained within green coffee beans. It plays a crucial role in firmly holding the rich aromatic components (aroma) of coffee and making the mouthfeel smooth.

One of its charms is that the amount of oil poured into the cup is adjusted by the brewing method, dramatically changing the flavor profile.

・Paper Filter Extraction:

Since the paper absorbs oil appropriately, the taste is clean and clear, free from雑味 (unpleasant flavors). ・Metal Filter/French Press: The oil passes directly through the liquid, allowing you to dynamically enjoy the direct, deep richness and umami inherent to the beans.

・Espresso Extraction: By applying high pressure and extracting in a short time, the oil and water emulsify beautifully, creating a thick, rich foam layer called "crema" on the surface.

Thus, coffee oil is an essential natural umami component for enjoying delicious coffee.

[Why Does My Stomach Get Upset? The Problem Isn't the Oil, But "Oxidative Deterioration"]

You might wonder, "If coffee oil isn't the problem, why do I get a burning sensation in my stomach or heartburn after drinking it?"

The real cause is not the oil itself, but the "oxidation of old bean oils."

From the moment coffee beans are roasted, oxidation gradually begins due to oxygen in the air, light, and humidity. Especially for beans that have been mass-produced and stored for a long time, or beans that have been left ground for an extended period, the internal oils deteriorate into "peroxidized lipids."

Mechanism of Lipid Oxidation in Coffee Beans The unsaturated fatty acids contained in coffee beans are prone to oxidative deterioration when exposed to air. Oxidized oils strongly irritate the mucous membranes of the digestive organs and are one of the major factors causing dyspeptic symptoms such as hyperacidity, stomach pain, and heartburn. (From European Food Safety Authority (EFSA) food risk assessment data)

Oxidized oil burdens the body and causes unpleasant odors and an uncomfortable upset stomach. In other words, the problem is not the "presence" of coffee oil, but the "deterioration in quality" due to storage conditions and freshness.

We recommend freezing. Place them in a zipper bag like a Ziploc, remove the air, and freeze them. This prevents deterioration caused by oxidation.

[Summary: Enjoy the rich flavor of quality oil with freshly roasted, clean beans]

To prevent heartburn and headaches after drinking coffee, just as you would avoid "the four poisons (wheat, vegetable oils, dairy products, sweets)," the golden rule is to avoid ingesting "oxidized old oils" and "mycotoxins."

No matter how high-quality the coffee oil, if the beans themselves are old and oxidized, or if moldy defective beans are mixed in, they will cause unnecessary inflammatory stress to the body.

Our exquisite mold-free coffee offers:

1. "Thorough hand-picking" by artisans to eliminate moldy beans

2. Verification of "no mycotoxins detected in all lots" by government-certified testing agencies

3. Prompt shipping "within 24 hours after roasting" to maintain ultimate freshness

We are committed to delivering only the freshest and cleanest beans before their oils begin to oxidize.

With fresh beans that haven't yet begun to oxidize, you can truly enjoy the supreme richness and sweetness of high-quality coffee oil without burdening your stomach.

Once the beans arrive, store them in an airtight container and consume them while their flavor is fresh. That is the secret to enjoying the best cup while taking care of your body.

May you have a clear day today with clean energy, completely free of unnecessary noise.
