For a long time I have wanted to write a blog post on the (possible) health benefits of lambic beer. I am not sure if one could argue that lambic is healthy in terms of extending the average human lifespan (let alone the maximum human lifespan!), not to mention the risk of alcoholism, but there are a number of aspects about traditional lambic beer that compare favorably to most other beer styles.
1. The most obvious characteristic of lambic beer is that it is the product of both yeast and bacterial fermentation. As a result, lambic beer is much more of a probiotic than most other beer styles and may contribute to healthy gut flora. In addition, if you believe that humans do best to adapt to a diet and lifestyle closer to our ancestors (such as adherents of the Paleo Diet), lambic beer is a more logical choice (or, at a minimum, the least harmful) than modern pasteurized and bacteria-deficient beers.
2. Another interesting characteristic of lambic beer is that it is typically fermented bone dry with little residual sugar (Cantillon beers are a good example). This does not make it an “ideal” drink for diabetes patients, but you can certainly do a lot worse by drinking beer styles that have a lot of residual sugars such as imperial stouts or barley wines.
3. Another interesting aspect about lambic beer is that is has relatively low amounts of hops. The phytoestrogens in hops have been identified as potent inhibitors of testosterone, which supposedly contributed to hops becoming dominant as the sole herb (at the exclusion of more, well, “sexually potent” herbs) among Protestant reformers. When we think of testosterone we usually tend to think of body builders and juvenile aggression but testosterone has a number of important physiological roles in the human body for both males and females. One interesting question is whether the tradition of contemporary lambic brewers to use oxidized hops makes a difference, too.
4. Lambic beers are typically lower in alcohol. Unless you are an American “wild ale” brewer who believes that “more is more,” or you are a lambic brewer called Boon, lambic beer usually has a modest alcohol percentage between 4.5% and 6%. Alcohol is a strong diuretic and, like hops, has been associated with lower testosterone levels, too.
5. A number of lambic brewers (yet again, Cantillon) lean strongly towards the use or organic ingredients and abhor the use of artificial ingredients or processes.
Caveats and additional thoughts:
Clearly, this post is not the final word on the health aspects of lambic beer and some of these benefits may need to be further qualified or may turn out to be non-existent or only applicable to certain populations, genders, and age groups. It should be obvious that almost everything that I have said here applies to traditional lambics, not the pasteurized, sweetened beers that, unfortunately, use the same name. It should be rather obvious, too, that most of what is said here also applies to many American “wild ales,” provided alcohol and hops are kept at reasonable levels and added fruit is allowed to ferment to dryness.
Instead of thinking of lambic as a specific beer style we can also think of it as a framework to approach brewing in general. This opens up the possibility of reinventing many traditional beer styles and allowing elements of the lambic brewing process to play a role in these other kinds of beer. For example, the use of wild yeast to lower residual sugar in a beer or the addition of (wild) bacteria.
Most people do not drink beer for its health benefits, but it would be interesting to think about how to further improve the health aspects of lambic beer. What about using a different herb than hops to inhibit proliferation of undesirable bacteria and further enhance its health benefits (making a so called wild gruit)? What about blending lambic with red grapes such as in Cantillon’s Saint Lamvinus, or blending it with wine or kombucha as some experimental brewers have recently done? It is conceivable that beer will always lose against red wine (of the “natural” variety that is) in terms of health benefits, a price that some beer drinkers will not mind paying. Then again, lambic drinkers often like wine too, so choosing the right proportions may be just what the doctor ordered (sic)…
