Yes, you can use espresso beans to make drip coffee.
First, we need to understand the difference in the use of coffee beans between espresso and drip coffee. Espresso requires coffee beans that are roasted darker, have a shiny surface, and are ground very finely, like powdered sugar. This is because the finer the coffee beans are ground, the shorter the coffee extraction time, which usually takes about 25 seconds. The coffee beans of drip coffee are not ground as fine as espresso. They are of medium fineness and are about the same size as sand on the beach.
Now that the espresso beans have been roasted dark enough and ground finely enough, they meet the basic requirements for making drip coffee. When making drip coffee, we only need to put the ground espresso beans on the filter paper, put it into the drip pot, and then brew it with hot water of about 85 degrees. After the coffee is filtered and extracted, it slowly drips into the cup.
It's worth noting that because espresso beans are ground finer, the coffee may be extracted faster during the drip process than with regular grinds. This means you'll likely get a stronger cup of drip coffee with a higher caffeine content.
In addition, if properly stored, drip coffee can maintain temperature and aroma for more than two hours, which is much stronger than espresso. So, if you like a rich taste and long-lasting aroma, using espresso beans to make drip coffee is a good choice.
To sum up, you can use espresso beans to make drip coffee, you just may get a different taste and aroma than the conventional method. You can experiment and adjust to your own taste.
