Why does the coffee dissolve in the water?
The reason we use water to make our daily coffee is because of its properties. Because as an odorless and colorless liquid, water has the ability to best extract all the qualities of coffee, such as the quality of the grain, the roast and many other properties.
On the other hand, if we use other liquids to prepare coffee, such as natural milk, due to its composition, it can completely change the characteristics and taste of the coffee, giving it new textures.

Does coffee dissolve faster in hot or cold water?
Coffee dissolves much faster in hot water than in cold water. There are many reasons for that.
Depending on the amount of coffee used, coffee can dissolve in water that is already heated or boiled for 20 to 30 seconds, while it can take up to 2 minutes for small amounts to dissolve in cold water.
There’s a reason for this: when coffee comes into contact with water, it’s usually ground and in that state is considered a solid. When the water is hot, the particles form much more interstitial space, allowing more surface area to come in contact with the water and coffee. Due to the increased contact of the solid with the water, the amount of solid that dissolves is much greater than the amount that dissolves in cold water.
How long does it take for coffee to dissolve in the stomach?
After drinking coffee, the stimulating effect can occur after 20 and 30 minutes for some people. After this time, we can begin to feel the effects of the caffeine in our bodies .

Does the taste of the coffee change when brewed with hot or cold water?
The coffee taste changes depending on the water used for the preparation. But this is an issue that depends heavily on taste and the desired preparation. Because there are people who claim that cold coffee is much less acidic than hot coffee and is therefore easier to combine with other ingredients such as red fruit, whipped cream and many other foods. But according to studies from the United States, the pH (a measure of acidity) of cold coffee and hot coffee is not significantly different.
Compare cold and hot coffee at home
For curious coffee drinkers we have a very simple experiment: you only need a couple of glasses, two tablespoons of coffee, cold and hot water.
- Fill one glass with cold water and the other glass with the same amount of hot water and wait until the water is completely still.
- Put a teaspoon of coffee in each glass.
- As the seconds pass, you will see how the coffee quickly dissolves in the glass of hot water while not moving in the glass of cold water.
This is because of what I explained earlier: the particles in the hot water expand and there is more contact area.
