Ever made instant coffee that tasted burnt, bitter, or just off? You might be boiling it to death without realizing it.
Most people pour 100°C boiling water over instant coffee, thinking it’s the best way to dissolve the granules. But here’s the problem:
🔥 Boiling water actually spoils instant coffee.
Why Boiling Water Ruins Instant Coffee ⚠️
When you pour boiling water directly onto instant coffee, it damages the delicate coffee compounds. Here’s what happens:
Burnt taste – The high heat scorches the granules, making your coffee bitter.
Lost aroma – Essential oils evaporate instantly, leaving a dull, flat taste.
Over-extraction – Boiling water pulls out harsh compounds, ruining smoothness.
The fix? Use water between 80°C and 90°C—hot enough to dissolve the coffee but gentle enough to preserve flavor.
That’s where the Bosch Variable Temperature Kettle comes in.
How to Make the Best Instant Coffee – Best Temperature for Instant Coffee
Step 1: Use the Right Temperature
Fill your kettle with fresh, cold water.
Select 80°C or 90°C using the touch panel.
The LED display will show when it's ready to pour.
Step 2: Prepare Your Coffee
Add 1-2 teaspoons of instant coffee to your mug.
If using sugar, add it before pouring water.
Step 3: Pour Slowly & Stir
Pour gently to avoid scorching the granules.
Stir immediately for even dissolving.
Step 4: Customize & Enjoy
Add milk, creamer, or plant-based alternatives.
Enjoy a smoother, richer coffee.
What If You Only Have a Standard Kettle? 🔥
If you don’t have a variable temperature kettle yet, you can still improve your instant coffee by letting boiled water cool before pouring.
⏳ How long should you wait?
After reaching 100°C, water naturally cools inside a closed kettle to:
90°C in ~5 minutes
85°C in ~7–8 minutes
80°C in ~10–12 minutes
💡 Quick tip:
Boil water first, then let it sit for 10–12 minutes before pouring. This helps you reach the best temperature for instant coffee without scorching the granules.
🚀 Want the right temperature instantly? Skip the wait—get the Bosch Variable Temperature Kettle and set it precisely to 80°C or 90°C at the touch of a button!
