Brewers have been known to describe pilsners as the hardest style of beer to produce. Good pilsners have clean, light malt flavors like grain and crackers, often backed up by herbal and grassy hops. There are only a few ingredients in most pilsners, and they're outwardly simple beers. This simplicity and minimalism means there's nowhere for a brewer to hide flaws in their method—imperfections are laid bare to taste and smell. That said, I was blown away by the generally high quality of the US-brewed pilsners we tasted for this roundup.
