The water in your coffee maker is heated to be boiled. Afterward, it is added to the coffee grinds. Before the coffee percolates into the jug the taste and caffeine are removed in this manner.

The bubbly water will no longer be carbonated after being heated. Because just like a kettle, the infused Carbon Dioxide will vaporize and disappear.

The good news is that carbonated coffee does exist. Although it is uncommon to find it on grocery store shelves, you may buy it online.
