How to Make Barley Coffee: Step-by-Step Guide

Quick answer

• Barley coffee is a caffeine-free alternative to traditional coffee.
• It’s made by roasting and grinding barley, then brewing it like coffee.
• You can use most coffee makers, but a French press or pour-over often works best.
• Start with a coarser grind than you’d use for espresso.
• Experiment with ratios to find your preferred strength.
• It has a nutty, slightly bitter flavor profile.

Who this is for

• Folks looking for a caffeine-free coffee experience.
• Anyone wanting to try a unique, earthy beverage.
• People who enjoy experimenting with alternative brewing methods.

What to check first

Brewer type and filter type

Your standard drip machine can work, but some methods shine. A French press or a pour-over cone lets you control the brew more precisely. If using a drip machine, a paper filter is standard. For a French press, it’s all about that metal filter.

Water quality and temperature

Good water makes good coffee, or in this case, good barley brew. Filtered water is your best bet. Aim for water that’s just off the boil, around 195-205°F. Too hot, and you can scorch the barley.

Grind size and coffee freshness

This is key for barley. You want a grind that’s coarser than espresso, maybe similar to a coarse sea salt. Too fine, and it’ll be muddy. Freshly roasted and ground barley is ideal, just like with coffee beans. If you buy pre-ground, use it up fast.

For the best flavor, start with high-quality, freshly roasted barley coffee beans. If you’re buying pre-ground, use it quickly.

Coffee-to-water ratio

This is where you dial it in. A good starting point is about 1:15, meaning 1 gram of barley to 15 grams of water. For a standard 12oz cup (about 350g water), that’s roughly 23g of barley. Adjust from there.

Cleanliness/descale status

Just like with regular coffee, a clean machine is a happy machine. Make sure your brewer and any filters are clean. If you haven’t descaled your coffee maker in a while, now’s a good time. Old residue can mess with the flavor.

Step-by-step (brew workflow)

Here’s how to get a good cup of barley coffee going.

1. Measure your barley. Use a scale for accuracy. For a 12oz cup, start with around 23 grams.

• What “good” looks like: Accurate measurement, consistent results.
• Common mistake: Eyeballing it. This leads to weak or overly strong brews. Use a scale.

2. Grind the barley. Aim for a coarse grind, like coarse sea salt.

• What “good” looks like: Evenly ground particles, no fine dust.
• Common mistake: Grinding too fine. This can clog filters and create a muddy cup. Coarse is the way.

3. Heat your water. Bring filtered water to just off the boil, 195-205°F.

• What “good” looks like: Water at the right temperature, not boiling aggressively.
• Common mistake: Using boiling water. This can scald the barley and create a bitter taste. Let it sit for 30 seconds after boiling.

4. Prepare your brewer. If using a pour-over, add your filter and rinse it with hot water. Discard the rinse water. For a French press, make sure it’s clean.

• What “good” looks like: A clean brewing setup, filter rinsed to remove paper taste.
• Common mistake: Not rinsing the paper filter. This can leave a papery taste in your final brew.

If you’re using a pour-over coffee set, remember to rinse your filter with hot water before adding the grounds.

5. Add ground barley to the brewer. Place the ground barley into your filter or French press.

• What “good” looks like: Even bed of grounds.
• Common mistake: Uneven distribution. This can lead to channeling and uneven extraction.

6. Bloom the barley (optional but recommended). Pour just enough hot water over the grounds to saturate them. Let it sit for 30 seconds. You’ll see it expand.

• What “good” looks like: Gentle bubbling and expansion of the grounds.
• Common mistake: Skipping the bloom. This releases CO2 and helps with even extraction. Don’t skip it.

7. Pour the remaining water. Slowly pour the rest of your hot water over the grounds in a circular motion.

• What “good” looks like: Steady, controlled pouring.
• Common mistake: Pouring too fast or all at once. This can disrupt the coffee bed and lead to poor extraction.

8. Brewing time. For pour-over, let it drip through. For French press, let it steep for about 4 minutes.

• What “good” looks like: A steady drip or a controlled steep.
• Common mistake: Brewing too long or too short. This affects strength and flavor. Stick to the recommended times.

9. Press (French press only). Gently press the plunger down.

• What “good” looks like: Smooth, even press.
• Common mistake: Forcing the press. This can push fine particles through the filter. Go slow.

10. Serve immediately. Pour your barley coffee into your favorite mug.

• What “good” looks like: A hot, aromatic beverage ready to enjoy.
• Common mistake: Letting it sit on a hot plate. This can make it taste burnt.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale or old barley	Flat, dull, or burnt flavor	Use freshly roasted and ground barley. Check roast dates.
Grind too fine	Muddy cup, bitter taste, clogged filter	Use a coarser grind, like coarse sea salt.
Grind too coarse	Weak, watery, under-extracted flavor	Adjust grinder to a finer setting, but still coarser than espresso.
Water too hot	Scorched flavor, excessive bitterness	Let water sit for 30 seconds after boiling (195-205°F).
Water too cool	Under-extracted, sour, weak flavor	Ensure water is within the target temperature range.
Incorrect coffee-to-water ratio	Too weak or too strong, unbalanced flavor	Use a scale and start with a 1:15 ratio, then adjust to taste.
Not rinsing paper filter (pour-over)	Papery taste in the final brew	Always rinse paper filters with hot water before brewing.
Forcing the French press plunger	Gritty, silty coffee at the bottom	Press the plunger down slowly and steadily.
Letting brewed barley coffee sit	Burnt, stale flavor	Serve immediately; avoid leaving it on a warming plate.
Using dirty equipment	Off-flavors, stale taste	Clean your brewer and accessories regularly. Descale as needed.

Decision rules (simple if/then)

• If your barley coffee tastes bitter, then try a coarser grind because too-fine grinds can over-extract.
• If your barley coffee tastes weak, then use more barley or a finer grind because you might be under-extracting.
• If your barley coffee tastes sour, then ensure your water is hot enough because too-cool water leads to sourness.
• If your barley coffee is muddy, then use a coarser grind and be gentle with the French press because fine particles are escaping.
• If your pour-over is dripping too fast, then grind a bit finer because a coarser grind lets water pass through too quickly.
• If your pour-over is taking too long to drip, then grind a bit coarser because a too-fine grind can clog the filter.
• If your barley coffee has a papery taste, then make sure you rinsed your paper filter thoroughly because that removes the papery residue.
• If your barley coffee tastes burnt, then ensure your water isn’t too hot and you’re not leaving it on a hot plate because those can scorch the grounds.
• If you’re new to barley coffee, then start with a French press because it’s forgiving and lets you taste the pure flavor.
• If you want a cleaner cup with less sediment, then a pour-over with a good paper filter is your best bet because it filters out more fine particles.
• If you find the flavor too intense, then reduce the amount of barley you use or increase the water because a lower ratio results in a milder taste.

A good starting point is a ratio of about 1:15 (barley to water by weight). For a 12oz cup (roughly 350g of water), that’s about 23 grams of barley. Adjust based on your preference.

What kind of grind do I need for barley coffee?

You’ll generally want a coarser grind than you’d use for espresso, similar to coarse sea salt. Too fine a grind can lead to a bitter taste and a muddy cup.
