Alcohol-free beer is increasingly popular and sought-after as people become warier of their alcohol intake. A few decades ago alcohol-free beer was a poor imitation, but these days it’s steadily improving and some examples can hold their own compared to the real thing. This graphic takes a look at how alcohol-free beer is defined, the range of ways in which it can be made, and how these methods work.
