Choosing the Best Instant Coffee for Iced Drinks

Not all instant coffee is the same. Some brands use fine granules. Others use larger crystals. Some use instant espresso powder.

Common Mistakes When Making Iced Coffee with Instant Coffee

Even simple recipes can go wrong. Watch out for these slip-ups.

  • Using only cold water to dissolve coffee. This causes clumps. Always start with a splash of hot water.
  • Adding too much ice too soon. This dilutes your coffee before it’s even mixed well.
  • Skipping the stir. Instant coffee settles fast. Stir before every sip.
  • Guessing the ratio. Too much or too little coffee throws off the whole drink. Stick to the chart above.
  • Pouring coffee last. Always pour your coffee mixture over the ice, not the other way around. It chills faster and mixes better.

Avoid these, and your iced coffee will taste right every time.
