Book review: Wild Brews by Jeff Sparrow

Wild BrewsHomebrewers are taught from the very beginning that sanitation is priority #1, and that anything growing in your beer other than saccharomyces (brewer’s yeast) is the worst thing possible, and as a result, we spend a lot of time cleaning and sanitizing. Wild Brews by Jeff Sparrow brings to light a tradition of making beer with saccharomyces in concert with a handful of other microorganisms, and it’s good.

Of these styles, most Americans would be lucky to have heard of a lambic beer before, most of us have not. Wild brews introduces us to a handful of beer styles going back hundreds of years, all made with wild organisms. While science has allowed us to identify many of these organisms, and Wyeast and White Labs have clean cultures available commercially, Sparrow tells us that nothing is quite the same as when you let nature take it’s own course.

These beers become more like a fine wine, a product of their environment (or terrior) and a product of decades if not centuries of developing a signature blend of microorganisms within the brewery, which cannot be replicated by pitching a culture from a lab. These organisims live in the very walls of the brewery, and most importantly, in the oak barrels that the beer is aged in.

Sparrow takes the reader through a history of wild brewing, highlights the most well-known styles, tells us where we might travel to find examples still being produced, and then spends several chapters getting down to the nitty-gritty of production, fermentation and packaging of these beer varieties, rich in tradition, and like a fine wine, worth the wait (some of these beers take 3 or more years to get from brew to bottle).

For styles, Sparrow covers Flanders Red and Brown ales, Lambics and Gueuzes. For each style, he provides a history and regional background, as well as a standard formula one could use to formulate a recipe, as well as a description of each beer’s flavor profile. In the history chapter, Sparrow covers not only the evolution of the different beer types, but the where and the why of it all, broken down by region. The chapter Drinking Wild Beer covers current breweries manufacturing wild beer, and what they have to offer, including some US breweries.

The rest of the book moves from the where and the why and into the how. Beer Souring Microorganisms covers the major bugs responsible for wild brewing, but the reader is reminded that there are many that are not catalogued as easily that play an important role in authentic lambic beers. Production Methods, Wild Fermentation, Fermentation and Maturation Vessels and Finishing the Beer continue to break down the process into additional chunks, walking the reader through each phase with plenty of information.

If you have ever had a sour or an acid beer, and want to learn more, I would strongly recommend this book. I know that after reading it, I’m not far away from my first beer made with more than saccharomyces.

Maine Beer Highlight: Allagash Coolship Cerise

Allagash Coolship CeriseIn December of 2007, Allagash Brewery began experimenting with Coolship brewing techniques. From Allagash:

Last month we brewed the first two of our spontaneously fermented beers at Allagash. In brewing these beers we are using an authentic, traditional process honoring the classic Belgian Lambic tradition, including the use of a cool ship, which we built specifically for these spontaneous beers.

The process begins with a specialized decoction mash, which utilizes the addition of both two row barley and raw, unmalted wheat. After the mash and sparge, we add aged hops during the boil, which are traditionally used because they impart many of the beer stabilizing benefits of hops without contributing bitterness. The use of aged hops (aged a minimum of three years) necessitates an unusually long boil of over four hours.

After boiling, rather than cooling the beer in a sterile environment and adding a brewer’s yeast culture, the hot wort is pumped to a cool ship in a special room designed specifically to make these beers. The cool ship is a commonly used tool in Belgium, but is rarely seen beyond Belgium’s borders, if at all. It is a large, open tray that is 12 feet long, 8 feet wide and 1 foot deep. Once in the cool ship the hot wort spends the night cooling from near boiling temperatures to about 60 degrees Fahrenheit. To facilitate the cooling process, windows in the cool ship room are left open overnight. The cool Maine air, containing natural bacteria and wild yeast, drifts in and cools the wort. As soon as the wort is cool enough, the natural airborne yeasts and bacteria are able to survive in what will eventually be the spontaneously fermented beer (it is these natural yeasts and bacteria which will ferment the beer, rather than a yeast added by the brewer). Next, the wort is pumped back into a brewery tank, where it will spend one further day before it is pumped into special French oak barrels. Within one to three weeks, spontaneous fermentation begins in the oak and will continue for over one year. After the yearlong fermentation this traditional beer will age in French oak for at least one more year, sometimes with the addition of fruits, before it is finally bottled.

This process creates beers with very complex flavor profiles after an extensive aging process. I received two bottles from Allagash, Cerise and Red. I haven’t tried Red yet, but I have tried Cerise, and I consider myself privileged to have had the opportunity.

Cerise poured a bright orange-yellow with a bright white head of very tight bubbles. The aroma was very complex, I found apples, pear, and cherry combined with some of the more difficult (funky?) aromas to identify which gave the impression of very tart flavors to come.

Tasting was equally challenging, similar flavors matching the aroma followed, fruits and malt, funk, and with a very dry and tart finish, somewhat cirtic and tannic, but not displeasing. After spending several minutes waffling over what flavors I was able to identify, I resolved to stop trying, and just to enjoy it. I savored the lone glass for a long time though dinner, making sure to share with my wife.

I am definitely looking forward to trying the Coolship Red, and the time when Allagash begins to release these beers for retail sale. Cheers, Allagash!
