Brew Strong Instant Coffee
Quick answer
- Use a good quality instant coffee. Not all brands are created equal.
- Measure your coffee and water precisely. Don’t just eyeball it.
- Heat your water to the right temperature. Too hot or too cool is bad.
- Let the coffee bloom. This is a key step for flavor.
- Stir thoroughly. Make sure all that coffee goodness dissolves.
- Consider adding a pinch of salt. It can tame bitterness.
- Experiment to find your sweet spot. What’s strong for me might be weak for you.
Who this is for
- The busy camper who needs caffeine, fast.
- Anyone who thinks instant coffee is just “okay” but wants better.
- Folks who appreciate a strong cup without the fuss of a full brewing setup.
What to check first
- Brewer type and filter type: For instant coffee, you’re essentially using your mug as the “brewer.” The “filter” is the coffee itself dissolving. No paper filters here, thankfully. Just make sure your mug is clean.
- Water quality and temperature: Tap water can have off-flavors. Filtered water is usually best. For temperature, aim for around 195-205°F (90-96°C). Boiling water can scorch the coffee. Let it sit for about 30 seconds after it boils.
- Grind size and coffee freshness: This is where instant coffee differs. It’s already processed. What matters is the quality of the instant granules. Look for brands that mention “freeze-dried” or “specialty” if you can. Stale instant coffee tastes flat. Keep your container sealed tight.
For the best flavor, look for high quality instant coffee, especially those that mention ‘freeze-dried’ or ‘specialty’ processing.

- Coffee-to-water ratio: This is your main lever for strength. A good starting point is 1-2 tablespoons of instant coffee per 6 oz of water. You can adjust from there. More coffee, stronger brew. Less coffee, weaker brew. Simple as that.
- Cleanliness/descale status: Even with instant, a dirty mug or spoon can mess with your taste. Give everything a quick rinse before you start. No need to descale a mug, but a clean mug is key.

2. Heat your water.
- What to do: Bring fresh, filtered water to just off the boil. Around 195-205°F (90-96°C).
- What “good” looks like: Small bubbles forming, but not a rolling boil.
- Common mistake: Using boiling water straight from the kettle. This can make the coffee taste bitter.
- How to avoid it: Let the kettle sit for about 30 seconds after it boils before pouring.
3. Measure your instant coffee.
- What to do: Use a measuring spoon. Start with 1.5 to 2 tablespoons per 6 oz of water for a strong cup.
- What “good” looks like: Precise measurement ensures consistency.
- Common mistake: Guessing the amount. This leads to weak or overly strong coffee.
- How to avoid it: Use actual measuring spoons, even when you’re rushed.
4. Add coffee to your mug.
- What to do: Spoon the measured instant coffee into your clean mug.
- What “good” looks like: Coffee granules sitting neatly in the bottom.
- Common mistake: Adding water first. This can cause clumps.
- How to avoid it: Always put the dry coffee in the mug before the water.
5. Add a small amount of hot water (the bloom).
- What to do: Pour just enough hot water to saturate the coffee granules. About 1-2 tablespoons.
- What “good” looks like: The coffee will bubble and expand slightly. This is the “bloom.”
- Common mistake: Adding all the water at once. You miss the bloom and potentially trap flavors.
- How to avoid it: Be patient. This short wait makes a difference.
6. Let it bloom.
- What to do: Wait 20-30 seconds for the coffee to release its gases.
- What “good” looks like: A slight puffing or bubbling action.
- Common mistake: Skipping this step. You’re leaving flavor potential on the table.
- How to avoid it: Just take a deep breath and enjoy the aroma for a moment.
7. Add the remaining hot water.
- What to do: Pour the rest of your hot water into the mug.
- What “good” looks like: The mug is filled to your desired level.
- Common mistake: Overfilling the mug. Spills happen, especially outdoors.
- How to avoid it: Leave a little room at the top for stirring.
8. Stir thoroughly.
- What to do: Use a clean spoon to stir until all the coffee granules are dissolved.
- What “good” looks like: No gritty sediment at the bottom. A smooth, dark liquid.
- Common mistake: Not stirring enough. You’ll end up with undissolved coffee at the bottom.
- How to avoid it: Keep stirring until you can’t see any more dry particles.
9. Additions (optional).
- What to do: Add milk, cream, sugar, or a tiny pinch of salt to taste.
- What “good” looks like: Your coffee is perfectly customized.
- Common mistake: Over-sweetening or over-milking. It masks the coffee flavor.
- How to avoid it: Add sweeteners and creamers gradually, tasting as you go.
10. Enjoy your strong cup.
- What to do: Sip and appreciate the quick, strong caffeine hit.
- What “good” looks like: You’re awake and ready for the day.
- Common mistake: Rushing the first sip when it’s too hot. Ouch.
- How to avoid it: Let it cool for a minute or two.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using stale or low-quality instant | Flat, papery, or bitter taste. Weak coffee. | Buy better quality instant coffee. Store it sealed and dry. |
| Using water that’s too hot | Scorched coffee flavor, bitterness. | Let water sit for 30 seconds after boiling. Use a thermometer. |
| Not measuring coffee/water | Inconsistent strength. Too weak or too strong. | Use measuring spoons and cups. Write down your preferred ratio. |
| Skipping the bloom step | Less developed flavor, potential bitterness. | Add a little water first, let it bubble for 20-30 seconds. |
| Not stirring enough | Gritty texture, undissolved coffee at the bottom. | Stir until no granules remain. Scrape the bottom of the mug. |
| Using dirty mugs/spoons | Off-flavors that ruin the coffee. | Always use clean gear. Rinse your mug and spoon before brewing. |
| Using poor quality water | Off-tastes from tap water or impurities. | Use filtered water. Spring water can also be a good option. |
| Adding too much coffee | Overpowering, undrinkable bitterness. | Start with the recommended ratio and adjust down if needed. |
| Adding too little coffee | Weak, watery coffee that doesn’t hit the spot. | Start with the recommended ratio and adjust up if needed. |
| Assuming all instant is the same | Missing out on surprisingly good instant coffee. | Try different brands; freeze-dried specialty options are best. |
Decision rules (simple if/then)
- If your instant coffee tastes bitter, then reduce the water temperature slightly because hotter water can extract more bitter compounds.
- If your coffee tastes weak, then increase the amount of instant coffee you use because more coffee grounds mean a stronger brew.
- If your coffee has a papery or stale taste, then try a different brand of instant coffee because quality varies greatly.
- If you notice sediment at the bottom of your mug, then stir more thoroughly next time because undissolved coffee creates a gritty texture.
- If your coffee tastes bland, then ensure you’re using fresh instant coffee and letting it bloom because these steps enhance flavor.
- If you’re in a hurry, then skip the fancy additions and focus on the coffee-to-water ratio and water temperature because those have the biggest impact on strength.
- If your tap water has a strong smell or taste, then use filtered water because it will make your coffee taste cleaner.
- If you want to avoid bitterness, then consider adding a tiny pinch of salt to your mug before adding water because salt can neutralize bitter flavors.
- If your instant coffee clumps, then make sure you add the coffee to the mug before the water because this helps it dissolve more evenly.
- If you want a really intense coffee flavor, then use slightly less water because a lower water-to-coffee ratio makes a stronger drink.
FAQ
Q: Can I really make “strong” instant coffee?
A: Absolutely. It’s all about ratios, water temp, and the quality of the instant coffee itself. Don’t settle for weak.

A: A good starting point for strong coffee is 1.5 to 2 tablespoons per 6 oz of water. Adjust to your preference.

A: Yes, it does. Letting the coffee degas for 20-30 seconds with a little hot water helps unlock more flavor and reduces bitterness.

A: You can, but it won’t dissolve properly and won’t extract much flavor. Hot water is essential for good instant coffee.

A: Try using slightly cooler water, ensuring you didn’t use too much coffee, or add a tiny pinch of salt.
Q: How do I store instant coffee to keep it fresh?
A: Keep it in an airtight container, away from heat and moisture. A cool, dark pantry is ideal.
Q: Is adding milk or sugar the same as making it stronger?
