The coffee you can purchase in supermarkets is flavored with synthetic or natural oils, and some have at least fifty flavoring agents and preservatives. If you're looking to spice your coffee, you can try different flavors of coffee or, if your preferred coffee flavor isn't readily offered in supermarkets, we have a few methods to create your own coffee with flavor.

Add your favorite spice blend to your beans and keep them in a closed container to keep them for a couple of hours prior to grinding. Be aware about the temperatures you'll store the beans at as you'd like the flavor to be absorbed into the beans but you don't wish to see them melt into the beans. 

Do not keep them in a single container for an extended time. If they are stored for a long time it is possible that the spice will overwhelm the flavor of your coffee. When grinding them you could get a strong cinnamon flavor of coffee. If you want you can also get exotic natural flavors like hazelnut online via https://greatoutdoorscoffee.com/collections/flavored-coffee.

If you're not planning to use the beans for a while, remove the spice and don't store them for longer than one day, so that when you do make use of coffee beans later, cinnamon won't be excessively strong.

When you are grinding, you can include the spice during this process. Mix the beans and grind them using the spice you prefer. Be sure that the spice you choose does not overpower the taste of the coffee too. Be sure to get the correct proportion of spices and coffee since if you add too many coffee beans and too little spice, it won't be effective. 

If you add excessive spices in, the taste from the espresso will be completely gone. It's going to be very difficult to restore the flavor and taste afterward. It will be evident when you are preparing the dish by the aroma and flavor. 

Be careful about the amount of spice you include. It is impossible to physically separate them once they're present in the form of powder. Before you make a lot of batches from coffee mixture, make certain to try the mixture with just one cup of coffee before you make any other.
