Is there formaldehyde in beer? This question was recently submitted by a reader, and to tell you the truth I did not know much about the formaldehyde in beer issue. My initial reaction was "of course there is not formaldehyde in beer", but as I dug deeper into the research I began to grow concerned.

 

Now when I hear "formaldehyde" I think of preserving corpses… not exactly getting me in the mood for a cold one. So to start off I figured a definition of formaldehyde was in order:

 

Formaldehyde: a chemical used in manufacturing and chemical industries, and as a preservative by anatomists, embalmers, and pathologists. Being exposed to formaldehyde may increase the risk of developing leukemia and brain cancer.

 

So not only do I now think of corpses, but now I have brain cancer on the brain…. I am really hoping this does not turn out to be true at this point.

 

As I began my research into this question, a few things became clear:

 

* There appears to be some truth to the rumor in Chinese beers,

* There does not seem to be strong evidence of this rumor outside of China

* There does not seem to be a definitive answer on the subject

 

China appears to use formaldehyde

 

First of all, why on earth would breweries knowingly use formaldehyde? As it turns out it is a very inexpensive clarifying agent that lightens the color of the beer and extends its shelf life. Although some Chinese breweries claim that they have discontinued the practice, there are a number of beers sold in China that are very cheap and low quality (intended to be affordable to the masses), and it has been stated that these lower quality brews still use formaldehyde to keep costs down.

 

So how widespread is the use of formaldehyde in Chinese beer? I found a few articles dating back to 2005, where a representative of the China Alcoholic Drinks Industry Association (CADIA) is quoted as saying that 95% of the domestic beer in China has formaldehyde. What was that? Did you say 95% of domestic beers in China have a known cancer causing agent in them? Not really making me want to drink a Chinese beer.

 

Furthermore, an article in the "People’s Daily Online" reported in 2005 that:

 

Chinese brewery giant Tsingtao has confirmed the safety of its product, saying the per-liter formaldehyde content of its product is much lower than the standard set by the World Heath Organization (WHO). The Tsingtao Brewery Co., Ltd. made the remarks in a statement it issued Friday in response to earlier domestic media reports putting Tsingtao beer’s formaldehyde content under suspicion. China’s State Administration of Quality Supervision, Inspection and Quarantine (SAQSIQ) also said that Chinese beer, including big-name Tsingtao beer, is safe to drink.

 

However, I did find some more recent resources stating that this practice is dying off (no pun intended) and that only some breweries are still permitting formaldehyde in the brewing process today. I was also not able to find any reference to formaldehyde in any beers that China imports to other countries, as it appears to only be used in their domestic versions.

 

Finally, I came across a research study done in 2006 which concluded that:

 

Formaldehyde was measured in 29 beers [out of 84 tested] (including 7 imported brands) using solid-phase microextraction with on-fiber derivatization. Formaldehyde levels were between 0.082–0.356 mg/L. None of the beer samples exceeded WHO drinking water criteria for benzene, trihalomethanes or formaldehyde. http://www.scientificsocieties.org/jib/papers/2006/G-2006-1102-469.pdf

 

No Evidence of Formaldehyde Use Outside of China

 

While I did come across a lot of discussion in online forums about formaldehyde in non-Chinese beers (especially beers from Southeast Asian countries), I was not able to find any evidence if this. There is a great article I found that discusses this (specifically in reference to a Thai beer called Singha) located here: http://lewbryson.com/formaldehyde.htm.

 

No definitive answer

 

In all of the research I conducted online, I was not able to find a clear definitive answer on the subject (besides the info on China). There was a ton of forum discussions full of opinion and conjecture, but not much in the way of evidence.

 

Many folks felt certain that some Asian countries used formaldehyde in the brewing process, while others questioned the assertion and compared it to the rumor about urine in Corona. Some of the most interesting discussions were very scientific in nature, with quite a few folks claiming that trace amounts of formaldehyde were a natural byproduct in beer. Since I am not very strong in the sciences I have not gone into an in depth discussion of these arguments.

 

However, I did want to point out one study that was mentioned in the research report listed above. In it they mentioned another study that looked at European beers:

 

Donhauser and co-workers9 examined beers from Europe, using a HPLC method, and showed that 65% of them contained detectable formaldehyde, although in many the level was close to the detection limit of 0.2 mg/L. (Donhauser, S., Glas, K. and Walla, G., Detection of formaldehyde in beer. Monatsschrift für Brauwissenschaft, 1986, 39(10), 364–368.)

 

This would seem to give some credence to the trace amounts argument, but I would love to hear from some other readers that are more versed in the sciences than I….. anyone know a little more about this?

 

All in all, formaldehyde does not appear to be a major concern for beer drinkers. However, I would still be a little weary drinking a beer in China.

 

 

PORTLAND, Ore. -- Five Oregon state lawmakers want to impose a hefty tax on beer and have introduced a bill that brewers say would cripple them.
Four Portland legislators joined a Springfield senator to introduce Oregon House Bill 2461, which would impose a $49.61 tax on each barrel of beer produced by Oregon brewers.
The tax would raise revenue for the state at a time when budgets are running in the red. Specifically, the bill says it would fund prevention, treatment and recovery programs for those addicted to alcohol and other substances.
The bill's language defends the tax by arguing alcoholism and “untreated substance abuse” costs the state $4.15 billion in lost earnings as well as more than $8 million for health care and nearly $1 billion in law enforcement-related expenditures.
Oregon ranks 49th among states in its malt beverage taxation rate, which has not been raised in 32 years, according to HB 2461.
Brewers hopping mad over tax
Brewers say Oregon's low beverage taxation rate is what makes the state such an attractive place for crafting beers. The state’s brewery guild claims it would also amount to the single largest beer tax hike in the nation's history.
Laurelwood Public House & Brewing Co. owner Mike De Kalb said the tax may sound like a good idea in this economic climate, but he believes it would cost jobs and not raise enough new tax revenue to justify the increase.
“We’re a family-owned, local Portland business. We don’t want to see something cost taxpayers more than the revenue it would bring in,” De Kalb said.
De Kalb said Oregon would potentially lose its prominence as a craft-brew destination and that some small breweries could potentially go out of business. He said Laurelwood could possibly face job cuts as well. Prior versions of the beer tax bill have exempted small breweries but this one does not, he added.
$1.50 more, or just 15 cents?
“If that tax is passed it would mean consumers would pay $315 million more (in 2009) to buy the same amount of beer they bought in 2008," De Kalb claimed. "A pint of beer would go from $4.50 to $6.”
Rep. Ben Cannon, one of the bill's sponsors, questions whether the true hit to consumers would be as high as beer makers claim. He told KGW his office measured the increase at 15 cents per glass not $1.50.
But Kurt Widmer of Widmer brewing told KGW that in order to keep profit margins constant, he'd increase his price to distributors, who in turn would likely increase prices to retailers, making the 15 cent per class estimate unrealistic.
House Bill 2461 has been introduced by Portland Reps. Ben Cannon and Michael Dembrow, Portland Sens. Jackie Dingfelder and Diane Rosenbaum, and Springfield Sen. William Morrisette.
