Most beer drinkers fall into two broad categories: hop heads or malt mavens. We have all been taught from our earliest brewpub visit, order an IPA if you crave hop bitterness or go for a doppelbock if you want some sweet malt. There is now a growing subculture of beer fans that want to pucker up: call them the sour patch kids.

Oud bruin, Flanders red ale, lambic, gueuze, gose, saison and Berliner weisse are styles that have been around for centuries so how can these be considered “new?” How can something that emerged during the seventeenth century be your Next Beer? Start counting the barrels. The corners of some breweries are starting to look more like Napa wineries or Kentucky rackhouses.

“We’ve been looking for something that people tired of getting slammed with hops might enjoy,” says Ron Gansberg, the talented brewer at Cascade Brewing in Oregon, pointing out that his sour beers are a unique northwest style and don’t try to mimic Belgian sours. “The thing about these beers is they provide an intense sensory experience that is something other than hops.”

That “sensory experience” emerges in the form of an acidic sourness that comes from a spontaneous source of fermentation that in most beers would be considered a major defect. Under normal circumstances the presence of Lactobacillus, Brettanomyces or Pediococcus in a brewhouse is a cause for concern. But for makers of oud bruin and Flanders red ale these organisms are welcome guests.

Keith Schlabs, food and beverage director for the 13-location Flying Saucer Draught Emporium chain, says his locations are selling more of these beers as they become available from importers and craft brewers. Most of the time it is in the bottle, since these beers still don’t sell consistently well enough to move kegs at the peak of freshness.

“Sour ales require a hand selling process, because there is a bit of ‘shock factor’ to the flavor. It is difficult for some people to get their arms around the taste of these beers. Until recently only serious beer connoisseurs really sought them out,” says Schlabs. “There is a time and a place for these beers, and there are some pretty good ones on the market. We see people sharing bottles quite often.”
