Quick Answer. Beer is an acidic beverage that has an average pH of approximately 4 to 4.5. Any pH below 7 is considered to be acidic while any pH above 7 is considered to be basic or alkaline. The pH level in beer is an important factor to consider when brewing beer.
If you think back to high school chemistry class, you may recall that pH is an abbreviation for potential hydrogen. A pH number measures from 0 to14 how acidic or alkaline a liquid is -- anything above 7 is alkaline and anything below 7 is acid. Water has a pH level of 7 -- it's neutral, meaning it has the same amount of acids and alkalis, which balance each other out. When you're thinking about liquids in terms of their pH levels, going up or down one number on the scale represents a tenfold change in the acidity or alkaline nature of a liquid. For example, the pH level of milk is around 6. Because the pH level of water is 7, milk is 10 times more acidic than water. Vinegar has a pH of about 3, making it 40 times more acidic than water [source: Carpi].
