If you were to asked to associate anything with the state of Utah, the first thing to come to mind would most likely be Mormons. Followed closely by Polygamy and then 3.2% beer. The first-two do in fact exist, but the latter is up to interpretation.
There are two ways to measure the alcohol content in a beverage. By weight or by volume. Most of the world measures the amount of alcohol in beer by volume. However in Utah, our regulators prefer that alcohol be measured by weight. Why? who the hell knows.
Anyway, if you were to measure our 3.2% (by weight) beer in the same fashion as everyone else (by volume), they're really 4.0% beers. This percentage is in many cases just slightly less than the average alcohol content of most mainstream beers.
The graphic above, (courtesy Uinta Brewing) simplifies it nicely. Compare a pint of Bud Light (4.2%abv) with; let's say... Bohemian Breweries Pilsner (4.0%abv) the difference is 0.2% difference or 2 oz. more per glass. Not much.
Draught Guinness, one of the worlds most beloved beers comes in at a whopping 4.2% abv. I'm not saying that Utah's beers run neck-n-neck (alcohol wise) with the rest of the worlds beers. But, they aren't as weak as you might think.
One more thing. These rules only apply to beers on tap or purchased outside of state run liquor stores. Uinta makes a fantastic barley wine that comes in annually at around 10.5% abv.
To be clear. There is no limit on the amount of alcohol a beer can have in Utah. It's just a matter of where you can purchase it (liquor stores). Class is over.
