You are probably wondering how fast coffee dissolve in hot water? Well, there is a scientific answer to that question. Coffee can dissolve at different speeds depending on the temperature of the water and how much sugar or milk is added to it. This blog post is all about how fast coffee dissolve in hot water!

How Fast Coffee Dissolve In Hot Water?

Hot water speeds up the dissolution of coffee ground. Most solids, including coffee become more soluble with increasing temperature. This is because heat increases molecular movement, causing more collisions between the water molecules and the solid. The higher the solvent’s temperature, the faster a coffee will dissolve.

Whereas in cold water, you would have to put a lot of effort to dissolve coffee; like stirring for several minutes. So coffee is more soluble in hot water.

What Is The Correct Water Temperature For Your Brewer?

It is essential that you brew coffee at the right water temperature to get the best extraction of flavors and substances. Extraction refers to dissolving flavors and substances from coffee beans into your cup.

For optimal extraction, the temperature of your water should be between 195 to 205 degrees Fahrenheit. This is hot enough to extract carefully and quickly, but not so hot that it’s uncontrollable. Colder water will result in flat, under-extracted coffee, while water that is too hot will also cause a loss of quality in the taste of the coffee. (However, cold brew does not need any heat.)

You may need to adjust the temperature depending on the type of coffee beans you’re brewing. For a lighter roast, use hotter water to help speed up the process of extraction. ​Darker roasts should be brewed for lower temps in order to avoid over-extraction and minimize bitter flavors that result from it.

If you are brewing the coffee manually, let the water come to a full boil, but do not over boil. Allow a minute for the hot water to rest before pouring it onto your coffee grounds.

Other Factors That Affect Extraction Of The Coffee

  • The coffee-to-water ratio should be between 1:16 and 1:18
  • Coffee grind size affects the rate of extraction. Finer grinds dissolve more quickly than coarse grinds. Coffee grounds should be of a consistent size to ensure that the coffee is extracted evenly, not under- and over-extracted.
  • As mentioned above, the ideal water temperature for brewing coffee is between 195 and 205 F.
  • Contact time between the coffee and water will determine how much is extracted. The longer coffee grounds are in contact with water, the more coffee will be extracted. There is a recommended brewing time for each method.

Some Other Related Questions

Does instant coffee dissolve in cold water?

The answer is yes. Instant coffee does not care about hot or cold water for its dissolving because instant coffee is nothing but dehydrated regular coffee. However, instant coffee takes longer to dissolve in cold water since it has less molecular energy than hot water.

Does boiling water burn coffee grounds?

Most traditional recipes actually call for letting the boiled water cool down before adding the coffee grounds. Boiled water (212 F – 100 C) should never be used as it will burn the coffee.

Is cold brewing coffee better?

When you brew your coffee, the temperature of the water is hugely important to how it ends up tasting. Brewing cold water produces changes from when the hot water is used; some of this difference in taste will be noticeable from the first sip. For example, cold brew coffee has a lot less acidity and bitterness compared to hot brewed.


I hope this blog help you know how fast coffee dissolve in hot water and control the temperature while brewing coffee. You may need to raise or lower the temperature depending on the type of roast you’re brewing.
