Feast your eyes on the newest Swiss invention: Coffee-beer, a "fermented coffee beverage" that has been patented in every major market around the world by Nestac (part of the Nestle empire). The beverage is basically a super-caffeinated liquid that pours like a beer but smells like coffee. No alcohol included. To make it, coffee beans are roasted and the chemicals that contain the natural aroma are collected in a cryogenic condenser and then converted to coffee oil. The rest of the roast are ground into powder, mixed with yeast and sugar and fermented for 4 hours at 22 degrees Celsius. This way, the yeast still metabolises but doesn't convert to alcohol. They then mix the oil in with the liquid and nitrogen and that is injected to make foam.
