Steps for Quickly Dissolving Instant Coffee in Cold Water

As we already mentioned, preparing instant coffee with cold water might take a little longer than the traditional method.

You would have to spend some extra minutes stirring to ensure the coffee dissolves, and that could be uncomfortable for you.

Well, we have got a trick that can help you dissolve instant coffee in cold water faster. Just follow the steps below:

  • Get a food processor or blender.
  • Add the instant coffee powder to the blender.
  • Then add sufficient cold water to the coffee in the blender. Also, add sugar and any other ingredient that has to dissolve in the coffee. You may also include ice.
  • Turn on the blender, going gradually from the lowest speed to the highest speed.
  • Blend the mixture for about 1-3 minutes until smooth.
  • Then serve.

Can Instant Coffee Dissolve in Cold Milk?

Yes, instant coffee will dissolve in cold milk. However, you have to consider the amount of milk you add to the coffee.

The taste you desire plus the volume of water used in the coffee will determine how much milk you need.

When adding coffee to milk, use the correct milk to water ratio. For instance, if you usually prepare a fixed amount of coffee with a fixed amount of water, you will need less water when adding milk.

If you add the same amount of water to the same amount of coffee while adding milk, your coffee may taste bland or watered down.

So, when adding coffee to instant milk, you could work with a 1 to 3 ratio: 1 part milk to 3 parts water.

To prepare coffee with cold milk, just follow your usual routine for hot milk. Add the instant coffee to a cup, add cold milk, and add cold water.

Then stir until all dissolves completely. Of course, this method might take some time, so you could start with some hot water or hot milk before adding cold milk.

You could also prepare your coffee with the blender method.

Final Take

Instant coffee dissolves in water at various temperatures, including cold water. But compared to hot water, it makes more time to achieve complete dissolution.

One can get around this delay by dissolving the coffee first with hot water before adding cold water. Alternatively, one could stir vigorously or let a blender do the stirring.
