Who doesn’t love ending the day with a cold one? Perhaps you like to sit down with a pint of smooth stout, or maybe you’re more in love with India Pale Ales. Maybe you like hefeweizens and their immense body, or you might prefer a brown or red ale. There’s a lot of room for diversity in the beer world, and that’s certainly part of the fun. Is there room for sour beer, though? If you haven’t tried any of the sours now coming to market, they’re definitely something different. Most find that they either love them or hate them, though declaring them as an “acquired taste” seems to be the best description. What are sour beers and what should you know about them?
Originally
Once upon a time, sour beers were pretty much the province of Belgian brewers. That’s not to say they didn’t develop anywhere else, but the Belgians were the ones famous for their sour brews. Most of those being developed by craft brewers today stem from the Belgian tradition, at least in theory if not in actual practice.
Why might craft brewers today drift away from the traditional ways of making sours? Mostly it’s because of the practice that allowed wild yeast strains into the brew during fermenting. Wild yeast can result in some, well, wild results and most brewers try to stay away from situations in which this type of unpredictability is common.
How Breweries Develop Sour Flavors
There are several ways that brewers can develop sour flavors within their brews. While there are still a handful of brewers that stick to the original method (mostly in Belgium), other options have been developed.
Yeast: There are two options available for brewers hoping to use yeast to create a sour brew. One option is to use old aging barrels with wild yeast in them – the way they did it in the beginning. You’ll find that this is employed mostly by traditional brewers still operating in Belgium. The other way is to intentionally introduce a particular strain of yeast to the mix known for creating those desired flavors. In the world of wine making, brettanomyces is something that must be avoided at all costs because of the unwanted flavors it imparts during the fermenting process. In the world of beer, it’s desirable, at least if you want to end up with a tart, sour brew.
Of course, as you might expect, there are problems when using a different type of yeast to what’s ordinarily used during the brewing process. Cross contamination is a very real threat that can ruin a good batch of beer, so brewers making use of this specialized yeast must keep their sours far away from their regular brews, going so far as to house their sour beer in a completely separate building.
Fruit: Another way to create sour beer is to use different types of fruit during the aging process to result in a secondary fermentation. Not only does the fruit impart its unique flavor characteristics, but it also brings additional yeast to the table, which will feast on the remaining sugars in the brew as well as the sugar from the fruit. Cherries and raspberries are both commonly used for this. Fruit can also be used mostly for flavoring – adding tartness to a brew in an attempt to increase its sourness. Apricots are favorites for this.
The Aging Process
One of the hallmarks of sour beers (other than the flavor, of course), is the lengthy aging process it must go through. While ordinary beers can age for just a little bit and be palatable, sour brews need to age for a much longer period – sometimes up to three years. That’s quite an investment in time, equipment and space for brewers, and sometimes the gamble doesn’t pay off even when the beer produced is exactly what’s intended. Many craft brewers find that their offerings are really only enjoyed by a few faithful fans and true sour beer lovers.
The Types of Beer
Technically, most any type of beer can be made sour. It just takes the right bacteria and a little bit of time. However, there are a few types that are known specifically as sour brews, including Flemish ales, guezes and lambics. Of the three, lambics are probably the most famous for their sourness. However, both German and American style sour ales are beginning to make headway in the burgeoning craft beer market.
You’ll find that one of the best things about sour beer is the fact that they can help bridge the various worlds in alcohol consumption. For example, a Flanders red might be an excellent option for a confirmed wine drinker, while fruitier sours can be excellent options for those who don’t like malt or hops particularly. While the name “sour” can be a turn off, you’ll find that the refreshing, tart nature of these brews can make a world of difference in your own drinking enjoyment, and can even bring non-beer lovers into the craft beer fold.
To help you get out and discover some new and interesting brews, here are some breweries that currently put out sours:
• New Belgium
• Cascade
• Lost Abbey
• Cigar City
• Goose Island
• Cantillon
• Allagash
Enjoy Them Any Time of Year
Sours are known for their refreshing flavors, their low alcohol content (relatively speaking) and their lesser body and hop flavor than IPAs and other brews. If you’re looking for something a bit different from the standard pilsner, lager or IPA, then why not give the world of sours a chance? You’ll find there are quite a few out there, but you’ll have to do some searching to get your mitts on one. Actually, that search can be half the fun here. Go out and enjoy a sour today, and you’ll get a glimpse of just how diverse and enjoyable the craft beer world truly is. Spring, summer, fall or winter, these brews make a great choice all year long.
