How do beer become skunked




















Humans are remarkably good at detecting 3-MBT -- just four parts-per-trillion of the compound can be noticeable, making it one of the most powerful flavors in beer. The reaction happens fast enough that a glass of beer can become noticeably lightstruck in seconds when exposed to direct sun.

Watch out where you set your brewski down at the next barbecue. Lightstruck beer is such a common occurrence that many folks just assume that Corona or Heineken is supposed to taste like that.

The truth is that skunky beer is flawed, and no brewer wants their beer to taste like the back-end of a skunk. You can now find cans of some of the most commonly affected beers like Heineken and Corona or Corona Familiar, which is the same beer as Corona Extra but packed in large, brown bottles , and these packages are a better representation of how the beer should taste.

Miller Brewing still uses clear bottles for some of their brands High Life , and they skirt the lightstruck issue by using specially formulated hop extracts that do not react with UV light to create 3-MBT.

But what makes beer skunky? However, skunkiness in beer is caused not by heat, but by light. In fact, skunky beer is often called lightstruck beer, which sounds way cooler than it actually is. Isohumulones also known as alpha acids , the bitter compounds in hops used in beer, are very sensitive to natural light artificial light affects them, too, but not nearly as fast , which triggers a chemical reaction. Some people can detect MBT at concentrations as low as one-billionth of a gram in a ounce beer.

Canned beer offers the best protection against damaging light waves, and brown bottles rate a close second. His favorite beers are hop-forward and unique.

No light gets in, so no possibility of skunking. Helpful article. Hey Jennifer! Skunking happens because of light, therefore beer in kegs, cans, and totally opaque bottles are immune. They use a hop extract to keep this from happening. Not that we would drink that shit. Lol just an interesting side Note. You got a reliable source? And that the brewers are so wrapped up in the image of their beers in green bottles that they are willing to let their beers get ruined on the way to markets? The amount of UV penetration is dependent on many factors including the color of the glass, weather, storage, and angle at which the UV penetrates.

UV penetration in HDPE and LDPE high-density and low-density polyethylene, respectively is typically measured only when the UV is penetrating at a degree angle, or high-noon depending on where the testing is occurring on the globe. The handling of the glass from place to place and the additional packaging higher cardboard 6-packs for bottles of fine beer helps prevent some of the UV penetration as well.
