They’re hard to spell, even harder to pronounce and can be down-right confusing to differentiate from one another. Sour beer is the oldest type of beer in history. Next to these two dominating beer categories, other genres tend to take a back seat. At its worst, Brett can add poopy and Band-Aid flavors and aromas, but at its best it can make add a balancing layer of earthiness to a beer. It acts similarly to a yeast in that it eats up sugars in wort, but rather than converting them to alcohol the sugars are converted to lactic acid. One of the two bottles of L. helveticus at 30 ºC produced a biofilm and had a roasted aftertaste. When making sour beers, not only is yeast added but also a healthy does of bacteria. It’s traditionally brewed in the winter and aged for at least a year, and is often mixed with cherry and raspberry. Established in 1836, one of the oldest breweries still in operation that produces sour beer is the Rodenbach Brewery of Roeselare, Belgium. Gose is a top-fermenting beer that originated in Goslar, Germany. In traditional brewing, yeast is added to the hops mixture to ferment sugars into alcohol. Saccharomyces is then added for standard fermentation. Yoghurt – A range of dairy products including yoghurt are fermented with Lactobacillus and adding yoghurt containing a spectrum to wort of beer has been used in sour beer production. Still, many people remain unfamiliar with sours. Flanders: A Belgian beer that’s often fermented in large wooden vats. Goses range in flavor, but there’s always a balance between salty, herbaceous, and sour. And while the style was once hard to find, sours have become increasingly easy to get, thanks to craft breweries around the country. American wild ale: The craft brewer’s take on the sour is usually made with a mix of ale yeast and Brettanomyces yeast. While any type of beer may be soured, most follow traditional or standardized guidelines. Their extremely low hop count gives sour beers a taste unlike any other out there. Using adjuncts in sour brewing introduces slower-fermenting starches and extends fermentation in ways that create multidimensional fusions and turn beer into a culinary art. For instance, the citric and tart sour taste of the beer comes from lactic acid created by a bacteria called lactobacillus. With the increased consumption of sour beers (containing lactic acid) comes a demand to be able to produce such beers in a convenient and controlled way such as using dried bacteria in pitchable sizes. The highest acetic acid concentrations were produced at 20 ºC and in general decreased with increasing fermentation temperatures. Daily measurements of gravity and pH were taken over the course of the fermentation. 7-day free trial (no payment necessary) today! HPLC results indicate that the highest lactic acid concentrations were produced at 40 ºC by L. helveticus followed by L. acidophilus. Making sour beer doesn't need to be complicated or require long periods of aging! Your email address will not be published. Most lambics are blends of several season's batches, such as gueuze, or are secondarily fermented with fruits, such as kriek and framboise. This bacteria is responsible for sour beers like lambic and Flander Reds. Lactobacillus can be categorised as hetrofermentative (producing lactic acid and other byproducts such as CO2 and Ethanol) and homofermentative strains which produce lactic acid alone. Lactic acid is the primary acid in sour beers, along with carbonic acid from dissolved carbon dioxide, and is produced by lactic acid bacteria (specifically Pediococcus and Lactobacillus). Beer October 22, 2013 2 Comments. Pediococcus, aka pedio, is also a bacteria, not a yeast. For example, B. bruxellenis tends to produce more earthy, woody and musty notes versus fruity, pineapple esters that would be associated with B. claussenii. They’re tart, surprising and stun you at first sip. It’s risky business, but worth it for the tart, pungent and sour flavor these beers are known for. Acetobacter is less common bacteria, which is usually held to a minimum in the fermentation of most sour beers because it consumes ethanol to produce harsh-tasting acetic acid.

Over time, pediococcus can also create diacetyl, a compound that has a buttery taste. 6 lactic acid bacteria strains were fermented in 12 % unhoped malt extract at four different temperatures. Beers brewed in the United States utilizing yeast and bacteria strains instead of or in addition to standard brewers yeasts. Lactobacillus produces lactic acid very rapidly, imparting a soft and tangy flavor.

Think of it as the yogurt of the beer world. Based on encouraging results with a L. plantarum strain it was decided to evaluate a wider range of available dried lactic acid bacteria. The beer’s character is also influenced by the acids and alcohols available to be combined into esters during fermentation. Pedio is the other common lactic acid bacteria used in sour beers, as well as in other culinary roles like the acidification of sauerkraut and traditional dried sausages. Sour beer is beer which has an intentionally acidic, tart, or sour taste. The draw back to acidifying with pedio is that most strains produce concentrations of diacetyl above the taste threshold. Balanced acidity and an overall harmonious complexity are desirable in most sours, along with the absence of jarring off-flavors or obvious flaws. But with time, sour beers become a delicious balance that we think would be perfect for anyone that isn’t fond of the classic hoppy beer flavor.
