Craft beer maker descend on Beijing

However, there is a lot more to it than that, for after all it is the beers themselves that truly make this event.

Organizers say that the beer being sent to the festival includes some of the most sought after and most interesting brews. For example, Two-Hearted Ale, an IPA from Bell's Brewery of Michigan, was named best brew in the US in 2017 in the 15th annual ranking published by Zymurgy Magazine in association with the American Homebrewers Association.

Also present will be Cyclo Stout from Pasteur Street in Vietnam, which won a gold medal at the 2016 World Beer Cup.

"These beers are not only unavailable in all of China, but also difficult to try anywhere in the world," Setzer says.

"Most of the breweries will be sending brewmasters and brand creators to attend the fest and pour their beer for you. This will allow you unprecedented access to pick their brains and learn about their beers as you try them. Like what exactly is the difference between a kettle sour and a Lambic? How long did your barrel-aged stout sit in the barrel? What made you decide to brew your beer with these ingredients?"
