Brewing Coffee Using A Tea Strainer

Quick answer

• Yes, you can make coffee with a tea strainer, but it’s a bit of a hack.
• Expect a less refined brew, possibly with more sediment.
• It’s best for a quick, single cup when you’re in a pinch.
• Use a fine-mesh tea strainer for the best results.
• Grind your coffee coarser than usual to avoid clogging.
• Be patient; the process will be slower than with dedicated coffee gear.
• You’ll likely need to experiment to get it right.

Who this is for

• Campers and travelers who forgot their coffee maker.
• Anyone curious about improvised brewing methods.
• People who want a single cup of coffee without much fuss.

What to check first

Brewer type and filter type

You’re using a tea strainer. That’s the whole point here. Make sure it’s clean. A fine-mesh one is your best bet. If it’s a super coarse one, you’ll get grounds in your cup, guaranteed.

Water quality and temperature

Tap water is fine if it tastes good. If it tastes like chlorine, use filtered water. You want your water hot, but not boiling. Aim for around 195-205°F (90-96°C). Let boiling water sit for about 30 seconds to a minute.

Grind size and coffee freshness

This is crucial. Use a coarser grind than you would for a drip machine. Think coarse sea salt. Too fine, and it’ll clog your strainer and make a muddy mess. Freshly ground beans are always better. If you can only use pre-ground, try to find a coarser grind if possible.

Coffee-to-water ratio

A good starting point is about 1:15. That means 1 gram of coffee for every 15 grams of water. For a standard mug (say, 8 oz or about 240g of water), you’d use roughly 16 grams of coffee. Adjust to your taste. This is where you’ll do most of your tweaking.

To ensure precise measurements for your coffee-to-water ratio, consider using a reliable coffee scale. This will help you achieve consistent results every time.

Cleanliness/descale status

Your tea strainer should be spotless. Any old tea or coffee residue will mess with the flavor. If your strainer has been sitting around, give it a good scrub with soap and hot water.

Step-by-step (brew workflow)

1. Heat your water.

• What to do: Heat water to just off the boil (195-205°F or 90-96°C).
• What “good” looks like: Steam rising, but no rolling boil.
• Common mistake: Boiling water too hard. Avoid this by letting it cool for 30-60 seconds after it boils.

2. Prepare your vessel.

• What to do: Place your tea strainer over a mug or carafe.
• What “good” looks like: The strainer is securely seated, not wobbly.
• Common mistake: Using a strainer that’s too small or doesn’t fit well. Make sure it won’t slip off.

3. Add coffee grounds.

• What to do: Measure your coarsely ground coffee and add it to the strainer.
• What “good” looks like: The grounds are evenly distributed in the strainer.
• Common mistake: Using too fine a grind. This will clog everything up. Stick to coarse!

4. Bloom the coffee (optional but recommended).

• What to do: Pour just enough hot water over the grounds to saturate them. Wait 30 seconds.
• What “good” looks like: The grounds puff up and release CO2 (they bubble).
• Common mistake: Pouring too much water at this stage. You only need enough to wet the grounds.

5. Pour the remaining water.

• What to do: Slowly pour the rest of your hot water over the grounds in stages.
• What “good” looks like: A steady, controlled pour. You’re not flooding the strainer.
• Common mistake: Pouring too fast. This can cause water to bypass the grounds and lead to weak coffee.

6. Let it steep.

• What to do: Allow the coffee to brew for 3-4 minutes.
• What “good” looks like: The water is slowly dripping through the grounds.
• Common mistake: Rushing the process. Patience is key here.

7. Lift and drain.

• What to do: Carefully lift the strainer and let it drain for a few seconds.
• What “good” looks like: Most of the liquid has dripped through.
• Common mistake: Squeezing the grounds. This can release bitter compounds. Just let it drip.

8. Discard grounds.

• What to do: Empty the used coffee grounds from the strainer.
• What “good” looks like: The strainer is clean and ready for its next job.
• Common mistake: Leaving grounds in the strainer. They can get sticky and hard to clean.

9. Taste and adjust.

• What to do: Sip your coffee. Is it too weak, too strong, too bitter?
• What “good” looks like: You’re happy with the flavor!
• Common mistake: Not making notes on what you did. Remember what worked for next time.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes weak, then add more coffee next time because you might be using too little.
• If your coffee tastes bitter, then use a coarser grind or shorter steep time because it might be over-extracted.
• If your strainer clogs immediately, then your grind is definitely too fine, so switch to a coarser one.
• If you see a lot of sediment, then your strainer might be too coarse, or you poured too aggressively.
• If the water is taking forever to drip through, then your grind is too fine, or you used too much coffee.
• If your coffee tastes sour, then your water might not be hot enough, or you need a longer steep time.
• If you’re making more than one cup, then consider using a larger bowl or pot to brew into.
• If you’re out camping, then make sure your water source is clean and safe to drink.
• If you have a French press, it’s generally a better tool for this method because of its built-in filter.
• If you want to improve the taste, try preheating your mug with hot water.
• If you don’t have a scale, use about 2 tablespoons of coffee per 6 oz of water as a starting point.

FAQ

Can I use a coffee filter with a tea strainer?

You could try placing a paper coffee filter inside the tea strainer, but it’s tricky to get it to stay put and might collapse. It defeats the simplicity of the hack.

Will my coffee taste like tea?

Not if you clean your tea strainer properly! Any residual tea flavor will definitely transfer. Make sure it’s spotless.

Is this method safe for my tea strainer?

Generally, yes. Just avoid using abrasive scrubbers that could damage the mesh. Hot water and mild soap are usually sufficient.

What kind of coffee beans should I use?

Any kind you like! But for this method, a medium or dark roast might be more forgiving with a coarser grind.

How long should I let the coffee steep?

Start with 3-4 minutes. You can adjust based on your taste. Too short is weak, too long is bitter.

What if I don’t have a tea strainer?

You could try a fine-mesh sieve, but it might be even harder to manage. A clean bandana or cheesecloth can work in a true survival situation, but it’s messy.

Is this better than instant coffee?

For most people, yes. It’s a more flavorful and satisfying cup, even if it’s a bit more work.

How much coffee should I use?

A good starting point is a 1:15 ratio of coffee to water. So, for an 8 oz mug (about 240g of water), use around 16 grams of coffee.
