Well, I guess now I’ve visited two of the World’s Highest Breweries. The Urban variety is claimed by Level 33 in Singapore. As you might surmise it is on the 33rd floor. I guess that is high.
Definitely not as high as the other World’s Highest Brewery I’ve been to - Periodic Brewing in Leadville, CO. At a bit over 10,000 feet it has a few floors on Level 33.
Im leaning towards Periodic as the better beers.
