I get this bud from Walgreen's and they have a horrible stocking procedure, I know for sure the beer is cold, then they let it get warm, then refridge it the cans are always sweating. It's been 5 times I've drank this bud from them and all the time my stomach kills me from it. I think it, for some reason, creates more gas lot of foam in my stomach, feeling like I have to burp, but cannot. I drink the same amount of beer on any given day from a good distributor and have no problems.
Side note to add, the beer also has a lemony taste to it, so I don't know exactly the chemical reaction,but I'm positive that going from cold to room temp, then cold again screws the beer. Fluctuating temperatures cause oxygenation of your beverage , but only over one or several years.
This may spoil your beer, but not "skunk" it. I have read that wine in wine cellars at around degrees celsius last the longest, and that unstable and fluctuating temperatures over many years will spoil your wine by oxygenation.

I don't know enough to answer, but will add this observation: The old legend that "Cold, Warm, Cold Again" skunks beer CAN'T be true: Coors is "Shipped Cold from the Rockies," or some such nonsense, but you can buy it warm in the store. Your Name. Your Email Address. In , researchers at the University of North Carolina at Chapel Hill figured out what causes the skunked beer phenomenon according to LiveScience … The scientists bombarded Isohumulones also known as alpha acids , the bitter compounds in hops used in beer, with lasers.
Not skunky. 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. A veritable recipe for skunky beer. Even brightly, artificially lit commercial coolers can spell disaster, as can the bottle itself. Clear, light-brown, blue and green bottles allow light to interact with -- and turn -- their contents in a matter of seconds.
Even dark brown bottles can, over time, let in too much light. When this happens, the bitter, light-sensitive compounds in hops known as isohumulones break down and bind with the beer's sulfur compounds. The result of this chemical reaction is a byproduct called 3-methylbutenethiol MBT , which is chemically similar to the stinky spray of an actual skunk. It's so off-putting that tasters have been known to detect MBT in minute amounts -- as low as one-billionth of a gram in a ounce milliliter beer.
Sometimes beer plagued by MBT is commonly called "light-struck" beer [source: Solis ]. However, some beers are brewed to taste skunky. Using particular strains of lager yeast and brewing conditions, some brewers are shooting for this distinctive, sulfur-infused result. A German-style Pilsner is a good example of this.
