How to Make Soybean Coffee Without Caffeine

If you’re avoiding caffeine but still want the ritual and flavor of coffee, soybean coffee might be your answer. This caffeine-free alternative replicates the color, aroma, and even some of the roasted depth of traditional coffee—without the stimulant effects. It’s also highly digestible and budget-friendly, making it appealing for health-conscious or budget-limited coffee drinkers.

To make soybean coffee, you roast dehulled soybeans at high heat, grind them to 60 mesh, and brew like regular coffee. The whole process takes less than an hour from raw bean to cup, and the result is a caffeine-free hot drink with a roasted nutty profile. No specialty equipment is required beyond a heat source, grinder, and sieve.

What Is Soybean Coffee?

Soybean coffee is a caffeine-free beverage made from roasted and ground soybeans. It mimics the appearance, flavor, and brewing method of traditional coffee but contains no actual coffee beans. The technique transforms soybeans through roasting to develop a rich, nutty, toasted aroma similar to dark-roast coffee. Though it lacks caffeine and the complex origin flavors of single-origin beans, it offers a familiar mouthfeel and can be brewed just like espresso or pour-over.

Why Make Soybean Coffee?

There are several reasons to try soybean coffee. First, it has no caffeine, so it won’t cause insomnia or jitters. Second, it’s easy on digestion—much gentler than regular coffee. Third, it’s significantly cheaper than specialty coffee beans. Fourth, it increases the value of soybeans, which are usually used for oil or animal feed. For those avoiding stimulants or seeking a budget-friendly alternative, soybean coffee is a practical solution. It also works well in baked goods like cookies or desserts, offering a roasted flavor without extra cost.

How to Make Soybean Coffee: Step-by-Step

1. Prep the Soybeans

Start with clean, dry soybeans. Rinse them 3–4 times under running water to remove dust, dirt, and debris. After washing, drain completely and use a hot air blower to fully dry the beans. Then, run them through a soybean dehuller or a rice milling machine to remove the skins. Finally, use a fan or blower to blow away all loose hull fragments.

2. Roast the Soybeans

Transfer the dehulled soybeans to a rotary roaster and heat them at 220°C for 30 seconds. For small batches, you can use a regular iron pan: roast the beans at around 160°C for 10–20 minutes until they develop a noticeable burnt-toast aroma. Once roasted, let the beans cool completely. Then, grind them using a food processor or impact mill until fine, and sift the powder through a 60-mesh sieve to achieve uniform particle size.

3. Brewing Your Soybean 'Coffee'

Brew the soybean powder just like regular coffee grounds. Use 90°C or hotter water for best results, as higher temperatures enhance the roasted aroma. For improved flavor, stir in a teaspoon of milk powder or sugar. The resulting drink is smooth, easily digestible, and free of bitterness or acidity. There is no crema or espresso-like body, but the roasted depth can mimic classic dark roasts in texture and color.
