Fake Coffee: How Chemical Coffee Essence Tricks Your Taste Buds

Next time you sip a rich, aromatic cup of what looks like coffee, consider this: it might not contain a single bean. In tests, people were served what looked and smelled like classic mocha or roasted coffee—but it was made with nothing more than synthetic flavoring, water, and emulsifiers. No coffee. No milk. No chocolate. Just chemicals.

Yes, you can replicate the color, aroma, and even flavor of coffee using just a few drops of store-bought coffee essence, some emulsifier, and sugar—no roasted beans required. And many people can’t tell the difference, even in a blind taste test.

What Is Coffee Essence?

Coffee essence—also called coffee flavoring or coffee concentrate—is a liquid flavoring agent sold in small bottles, often at chemical supply or food additive stores. A typical 30ml bottle of brown coffee essence, used to mimic the taste of coffee, can be purchased for as little as 50 TWD (about £1.20 or $1.50). Just 4–5 drops of this essence, combined with an emulsifier, can flavor up to 150ml of water or milk, creating what looks and smells like a full cup of coffee—for less than 1 TWD (around 2–3 pence or 4 cents USD) per serving.

How Chemical Coffee Is Made

Making fake coffee is disturbingly simple. With no coffee beans, milk, or cocoa involved, all you need are:

• A bottle of commercially available coffee essence (e.g., mocha or roasted coffee flavor)
• An emulsifier (to help mix the flavor with liquids)
• Sugar or sweetener (optional, for taste)

By mixing 4–5 drops of 30ml coffee essence with an emulsifier in 150ml of liquid, you can create a beverage that visually and aromatically resembles traditional brewed or instant coffee. The same method can produce flavors resembling popular styles such as "charcoal roasted" or "mocha."

The Blind Taste Test

In informal trials, four samples were presented to participants: two were made with commercial canned coffee (labeled C and D), and two were created using coffee essence and emulsifier (labeled A and B). All four cups were dark brown in color and emitted a strong coffee-like aroma. Despite the obvious visual and olfactory cues, several participants failed to correctly identify which cups contained real coffee—and some confidently claimed they were drinking genuine coffee when they were not.

What’s Actually in Coffee Essence?

The exact contents of these flavorings are often unclear. While Taiwanese regulators permit their use, the specific ingredients in local coffee essences are not well-documented. However, international sources suggest many such flavorings contain propylene glycol—a compound commonly found in cosmetics and some food products. Though approved for certain uses, excessive consumption of propylene glycol may lead to allergic reactions and place additional strain on the liver and kidneys.

Why Isn’t This Regulated?

Currently, there are no specific regulations governing the use of synthetic coffee flavorings or chemical additives in coffee-like beverages in Taiwan. These essences are openly sold in chemical supply stores, making it easy for anyone to produce synthetic coffee at minimal cost. The lack of oversight raises concerns over consumer transparency and long-term health impacts.

Frequently Asked Questions

What is coffee essence made of?

Coffee essence is a synthetic flavoring agent, often sold in small bottles. While the exact formula varies, some international sources indicate it may contain propylene glycol. It’s designed to mimic the taste and aroma of coffee without using any actual coffee beans.

How can you tell if coffee is fake?

In blind taste tests, many people couldn’t distinguish between real coffee and essence-based fake coffee. Visual cues like color and aroma can be replicated, making it difficult to tell the difference without lab testing or detailed ingredient disclosure.

Is coffee essence safe to consume?

The safety of coffee essence depends on its ingredients. Some versions may contain propylene glycol, which is generally recognized as safe in small amounts but could cause allergic reactions or strain organs if consumed excessively. Exact formulations are often not disclosed.
