Arsenic and Old Ale

The beer you are currently drinking might contain arsenic. Try not to worry about it, as your tap water probably does also. Arsenic is a naturally occurring mineral found in the soil. In many cases, it is in such low concentrations that it will not cause any health concerns. Even the Victoria Water Department tested for arsenic but didn't find any in our water supply. But some researchers were curious as to why some German beers contained higher amounts of arsenic than commonly found in water. In some beers, the amount of arsenic was higher than the 10 micrograms per litre limit set by the World Health Organization. It was determined that the arsenic was introduced during the filtering of beer. Many German breweries use a product called kieselguhr, or diatomaceous earth. This product was found to be a significant source of arsenic.
So what does this mean to craft beer lovers? Did mostly local, unfiltered beer. A simple and tasty solution. In an unrelated story, some people have mentioned that I look remarkably similar to Cary Grant.
