...to make sure you understand what numbers on the beer bottle means you need to know at least two of these: ABV and IBU. You can't really tell if you will like the beer, however at least you can approximately guess what type of beer it is.

What is ABV and IBU?

IBU = International Bitterness Units

IBU is a bitterness scale: 0 - 100.

Different people feel bitterness differently, yet it's still an easy scale to understand: bigger number means more bitterness.

ABV = Alcohol By Volume

Bigger ABV means more alcohol. Usually regular mass produced lagers are 4-5% ABV. Keep in mind, that difference in this number can be quite profound.

Difference between 4% beer and 8% beer is huge.

What is ABV and IBU?
