Brewing Tea From Green Coffee Beans

Quick answer

• Green coffee bean tea is made by steeping whole, unroasted coffee beans in hot water.
• The flavor is herbal and grassy, not like roasted coffee.
• Use whole green beans, not ground coffee.
• Aim for water just off the boil, around 195-205°F.
• Steep for 5-10 minutes, adjusting to taste.
• Start with a ratio of about 1-2 tablespoons of beans per 8 oz of water.

Who this is for

• Those curious about the health benefits of chlorogenic acid found in unroasted coffee beans.
• Coffee enthusiasts looking for a unique, caffeine-free (or low-caffeine) alternative beverage.
• Individuals seeking a mild, herbal-tasting drink without the bitterness or roast notes of traditional coffee.

What to check first

Brewer type and filter type

The method you use to brew your green coffee bean tea will depend on your preference. You can use a French press, a tea infuser, or even just a pot and a fine-mesh strainer.

• French Press: Ideal for steeping whole beans and then pressing them down.
• Tea Infuser: A good option for smaller batches or if you want to keep the beans contained.
• Pot and Strainer: The most basic method, requiring careful straining to remove all the beans.

If you prefer to keep your beans contained, a tea infuser is a convenient option for brewing smaller batches of green coffee bean tea.

For brewing green coffee bean tea, you’ll need whole, unroasted green coffee beans. You can find a good selection of these online.

Water quality and temperature

The quality of your water significantly impacts the taste of any brewed beverage, including green coffee bean tea. Filtered water is generally recommended.

• Temperature: Aim for water that is just off the boil, typically between 195°F and 205°F. Boiling water can sometimes extract too much bitterness.
• Quality: If your tap water has a strong taste or odor, it will likely transfer to your tea. Using filtered or spring water can yield a cleaner, more pleasant flavor.

Grind size and coffee freshness

For green coffee bean tea, you want to use whole, unroasted beans. Grinding them is not necessary and can lead to a muddy, over-extracted brew.

• Whole Beans: Using whole beans allows for a more controlled extraction and a cleaner cup.
• Freshness: While “freshness” for green coffee beans is different from roasted beans, using beans that haven’t been stored improperly (e.g., exposed to moisture or strong odors) will be best.

Coffee-to-water ratio

The ratio of green coffee beans to water is crucial for achieving a balanced flavor. This is a matter of personal preference, but there are good starting points.

• Starting Point: A common recommendation is to use 1 to 2 tablespoons of whole green coffee beans per 8 ounces of water.
• Adjusting: If the tea is too weak, increase the amount of beans or steep for longer. If it’s too strong or grassy, reduce the amount of beans or steep for a shorter time.

Cleanliness/descale status

Just like with coffee brewing, a clean brewing device is essential for good-tasting green coffee bean tea.

• Residue: Any leftover residue from previous brews (coffee or tea) can impart off-flavors.
• Descaling: If you use a kettle or other heating device, ensure it’s descaled regularly to prevent mineral buildup that can affect water temperature and taste.

Step-by-step (brew workflow)

1. Gather your green coffee beans and brewing equipment.

• What to do: Have your whole, unroasted green coffee beans, your chosen brewing vessel (French press, infuser, or pot), and your kettle ready.
• What “good” looks like: All necessary items are clean and within easy reach.
• Common mistake: Using beans that are not whole or have been roasted.
• How to avoid it: Double-check that you have specifically purchased “green coffee beans” and that they are whole, not ground.

2. Measure your green coffee beans.

• What to do: Measure 1-2 tablespoons of whole green coffee beans per 8 ounces of water. You can adjust this amount later based on your taste preference.
• What “good” looks like: An accurate measurement that aligns with your desired tea strength.
• Common mistake: Eyeballing the amount, leading to inconsistent results.
• How to avoid it: Use a measuring spoon for consistency.

3. Heat your water.

• What to do: Heat fresh, filtered water to approximately 195°F to 205°F. If you don’t have a thermometer, bring the water to a boil and let it sit for about 30-60 seconds.
• What “good” looks like: Water is hot but not vigorously boiling.
• Common mistake: Using water that is too hot, which can scorpen the tea.
• How to avoid it: Use a temperature-controlled kettle or let boiling water rest briefly before pouring.

4. Add green coffee beans to your brewing vessel.

• What to do: Place the measured whole green coffee beans into your French press, tea infuser, or directly into the pot.
• What “good” looks like: The beans are contained and ready for steeping.
• Common mistake: Overfilling the brewing vessel, which can hinder proper water circulation.
• How to avoid it: Ensure there’s enough space for the beans to expand slightly and for water to flow freely.

5. Pour hot water over the beans.

• What to do: Gently pour the heated water over the green coffee beans, ensuring they are fully submerged.
• What “good” looks like: All beans are saturated with water.
• Common mistake: Pouring water too quickly or unevenly, which can lead to inconsistent extraction.
• How to avoid it: Pour slowly and in a circular motion.

6. Steep the tea.

• What to do: Cover your brewing vessel and let the tea steep for 5 to 10 minutes.
• What “good” looks like: The water will take on a light amber or greenish hue.
• Common mistake: Steeping for too short a time, resulting in a weak, flavorless tea.
• How to avoid it: Set a timer and stick to the recommended steeping time, then taste and adjust for future brews.

7. Press the plunger (if using a French press).

• What to do: If using a French press, slowly and steadily press the plunger down to separate the beans from the liquid.
• What “good” looks like: The plunger moves smoothly without excessive resistance.
• Common mistake: Pressing too hard or too fast, which can force fine particles into the brew.
• How to avoid it: Apply gentle, even pressure.

8. Strain the tea (if not using a French press).

• What to do: If you brewed directly in a pot or used an infuser, carefully strain the liquid into your mug, ensuring no beans pass through.
• What “good” looks like: A clear liquid free of coffee bean particles.
• Common mistake: Using a strainer with holes too large, allowing bean fragments into the tea.
• How to avoid it: Use a fine-mesh sieve or a dedicated tea strainer.

9. Serve and enjoy.

• What to do: Pour the brewed green coffee bean tea into your favorite mug.
• What “good” looks like: A pleasant aroma and a light, herbal flavor.
• Common mistake: Adding too much sweetener or milk, which can mask the delicate flavor of the tea.
• How to avoid it: Taste the tea on its own first to appreciate its natural profile.

10. Clean your brewing equipment.

• What to do: Rinse and clean all parts of your brewing device immediately after use.
• What “good” looks like: No residual bean fragments or liquid left behind.
• Common mistake: Leaving equipment uncleaned, leading to stale flavors in future brews.
• How to avoid it: A quick rinse with hot water is usually sufficient for green coffee bean tea.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using roasted coffee beans	Brew will taste like weak, bitter coffee, not green coffee bean tea.	Ensure you are using whole, unroasted green coffee beans specifically.
Grinding the green coffee beans	Cloudy, muddy tea with over-extracted, bitter, and grassy flavors.	Always use whole green coffee beans for steeping.
Using water that is too hot	Can scald the beans, leading to a harsh, bitter, and unpleasant taste.	Let boiling water cool for 30-60 seconds before pouring (aim for 195-205°F).
Steeping for too short a time	Weak, watery tea with little flavor or aroma.	Start with 5-10 minutes and adjust based on your preference.
Steeping for too long	Over-extraction, resulting in a bitter and overly grassy flavor.	Use a timer and taste periodically. Reduce steeping time if it becomes too strong.
Using too many beans	Overly strong, bitter, and potentially unpleasant grassy taste.	Start with 1-2 tablespoons per 8 oz and adjust down if needed.
Using too few beans	Weak, watery, and flavorless tea.	Increase the amount of beans or steep time until the desired strength is reached.
Not using filtered water	Off-flavors from tap water minerals or chemicals can detract from the taste.	Use filtered or spring water for a cleaner, more neutral base flavor.
Not cleaning brewing equipment	Stale, off-flavors from old residue will contaminate the new brew.	Rinse and clean all brewing components thoroughly after each use.
Forcing the French press plunger down	Pushes fine particles into the liquid, creating sediment and cloudiness.	Press the plunger slowly and steadily with gentle, even pressure.

Decision rules (simple if/then)

• If the tea tastes weak, then increase the number of green coffee beans used for the next brew because a higher coffee-to-water ratio extracts more flavor.
• If the tea tastes too bitter, then reduce the steeping time for the next brew because prolonged contact with hot water can over-extract the beans.
• If the tea has a muddy texture, then ensure you are using whole beans and a fine-mesh strainer because ground beans or large holes in a strainer will lead to sediment.
• If the tea has a grassy flavor that is too pronounced, then try using slightly cooler water (around 195°F) because very hot water can pull out more vegetal notes.
• If the tea has an unpleasant, stale taste, then clean your brewing equipment thoroughly because residual oils or particles can impart off-flavors.
• If you want a stronger caffeine kick, then consider that green coffee bean tea generally has less caffeine than brewed roasted coffee, and you may need to steep more beans for longer, but it will still be less potent.
• If you are sensitive to caffeine, then be aware that green coffee beans do contain caffeine, though typically less than roasted beans, and adjust your intake accordingly.
• If the tea tastes flat, then try using freshly sourced green coffee beans because older beans may have lost some of their aromatic compounds.
• If the tea is too strong and overwhelming, then reduce the amount of beans or steep time because a balanced extraction is key to its subtle flavor.
• If you notice an unusual aroma, then check the freshness and storage of your green coffee beans because they can absorb odors.
