3 reasons Why coffee powder becomes hard
When your coffee hardens, you may blame the brand you are using. Sometimes you may be right, as the quality of some cheap and local brands is not up to par.
However, more often than not, the main culprit is you are not storing your coffee powder properly.
Coffee grounds or instant coffee powder are susceptible to heat, air, and moisture. Therefore, proper storage is essential to preventing them from hardening and extending their shelf life.
Moisture is a major factor that reduces the shelf life of coffee and contributes to its hardening.
Coffee stored in the refrigerator or in humid places is more likely to harden. Moisture also promotes the growth of bacteria and makes coffee taste stale.
When coffee grounds contact with moisture or drops of water, small clumps of coffee are formed, which get hard when the water dries off.
Higher temperatures encourage the growth of bacteria and molds. If you live in a hot and humid environment, your coffee grounds will stale more quickly.
So always keep the container of coffee ground in a cold environment away from the heat of the stove in your kitchen and make sure that it never comes in contact with the sunlight.
When coffee is exposed to air, it oxidizes, which causes it to stale more quickly. Air also carries away the aromatic compounds from coffee grounds, which are responsible for the sweetness and aroma of coffee.
Therefore, it is important to store coffee grounds in an airtight container.
5 Ways to Prevent Coffee Powder from Hardening
By following these 4 simple tips, you can ensure that your coffee grounds or instant coffee powder stays fresh and flavorful for longer.
1. Airtight container
Whether you buy fresh coffee beans or instant coffee powder, keep them in some air-tight glass or ceramic container.

4. Never put wet utensils in the coffee container
To prevent coffee powder from hardening, ensure that the airtight container is clean and dry before storing the coffee.
Avoid using wet utensils to scoop out the coffee powder, as this can introduce moisture.
5. Keep the coffee away from heat and light
Heat and light encourage the growth of bacteria which stales your coffee more quickly.
So always keep the container of coffee in some cabinet away from light, or keep it in some opaque container.
