Man, you are such a fucking kook.
Why is it that you harbor such mistrust for the "establishment" yet accept anything some yokel told you as the gospel truth as long as it makes the government look like a bunch of asses?
There currently are no federal regulations that dictate beer alcohol level, and since the end of prohibition there never have been. There are, however a couple of state laws that do. Utah, for example sets the limit at 3.2% and for a while Ohio had their limit set at 6% but they've repealed that law. Most states have no such restrictions.
It is federally illegal to advertise or promote your beer based on the alcohol content, and because of that law from 1935 to 1995 breweries were prohibited from putting the alcohol content on their beers. In 1995 the Supreme Court ruled that the Constitution protected as free speech the right to publish alcohol content as truthful information, and that's why you now see the alcohol content on the labels of breweries that choose to do so.
Sometimes alcohol content appears higher in imports than American beers because they use different measurements. The US measures alcohol by weight (because that's what the BATF decided on), and the rest of the world measures alcohol by volume. Since alcohol weighs less than water, the alcohol by weight measurement looks less than the alcohol by volume measurement.
Example: 4.1% ABW = 5.2% ABV.
So, if you were to hold a bottle of Molson imported into America next to a bottle of Molson purchased in Canada and compare the alcohol content it would indeed appear that the Canadian bought bottle had a higher alcohol content, but they're exactly the same.
About 90% of the entire world's beers alcohol content is near or below 5% ABV you stupid fuck. Do you know why? Because higher alcohol contents taste unpleasant to most people. Take La Fin Du Monde for example with it's 9% alcohol content... Brewed in Canada, bought in Pennsylvania, it's 9% ABV will fuck you up good but you can taste the alcohol a LOT and it's not as palatable as a brew with 5% ABV.
Which leads us to the next point. A major reason the American mega-brews are producing watery tasting swill is because of prohibition. Prior to prohibition American breweries produced full bodied and flavorful European style beers. Once alcohol was outlawed the bootleggers watered their beer down to stretch it further and in turn the American public became accustomed to lighter watery beer. As a result that's what the breweries produced after the repeal of prohibition. They gave the public what they wanted and in fact it's actually more difficult to produce Budweiser than it is to produce a quality craft beer.
Furthermore, the reason a beer tastes better in it's country of origin is because it's fresher, not because it was changed to meet your imaginary federal laws.
In conclusion, I'd like to add that you are a delusional piece of shit who should be locked away and heavily medicated. In the near future I'll be disguising myself as one of your close acquaintences so that I may monitor you more closely, and tell the Feds what the best time of day is for them to install their thought control devices in your house. Also, this thread is about marijuana you stupid old man who's a blonde cunt hair away from living in the park and yammering senselessly at passers-by.
