All types of beer have approximately the same alcohol content?

No, that's not true. Beer styles vary widely in their alcohol content.

Here are some examples:

* Light beers: Often have 3.5-4.5% ABV (Alcohol by Volume)

* Pilsners and Lagers: Typically around 4.5-5.5% ABV

* Ales: Can range from 4% to 7% ABV, with some reaching higher

* IPAs (India Pale Ales): Often 5-8% ABV, but some can be much higher

* Stouts and Porters: Can range from 4% to 12% ABV, with some reaching even higher

* Strong Ales and Barleywines: Typically 8% to 12% ABV or higher

So, while some beers might have similar alcohol content, many styles differ significantly.
