Important Note: The grounds, when dry
Before embarking on the exciting adventure of giving your coffee grounds a second life, it's essential to consider a crucial detail: coffee grounds should be used dry for most of their applications. Although it may seem like a minor detail, the difference between wet and dry coffee grounds is fundamental to the success of your projects.
Why dry? Dry coffee grounds retain their granular texture and natural properties, and while you can use them wet immediately for a peeling or to clean something, if they are not dried and stored properly they could develop mold: wet coffee grounds can develop mold.
To prevent mold in coffee grounds, it is essential to ensure they are completely dry before storing them in an airtight container or sealed bag. Also, store them in a cool, dry place away from moisture and direct sunlight.
So, before diving into the world of possibilities with coffee grounds, make sure to dry them completely.
How to dry coffee grounds
Drying coffee grounds is a simple process, it just requires a bit of time and care. Here is a small step-by-step on how to do it:
-
Collect the Wet Coffee Grounds: After making your coffee, collect the wet coffee grounds from the coffeemaker or filter.
-
Spread the Grounds Out: Place the coffee grounds on a baking tray or a flat surface in an even layer. Try not to pile them up so they dry evenly.
-
Let Them Air Dry: Leave the tray with the coffee grounds in a well-ventilated area or under indirect sunlight. Avoid direct sunlight, as this can negatively affect the quality of the grounds.
-
Stir Occasionally: During the drying process, stir the coffee grounds occasionally to ensure they dry evenly on all sides.
-
Wait the Necessary Time: Drying time may vary depending on ambient humidity and the amount of grounds you are drying (and the thickness when spread on the tray). It can take from several hours to a day or more.
-
Check for Dryness: To make sure the coffee grounds are completely dry, touch them with your hands. They should feel crisp and brittle when ready.
-
Store Them: Once dry, store the coffee grounds in an airtight container or a sealed bag until you are ready to use them in your projects.
You can also use the food dehydrator for this purpose! Place parchment paper on the trays of your dehydrator, and spread the grounds over them. Set it to 70 ºC and, if you have spread them in thin layers, you'll see they dry quickly.
