How bitter is a beer with IBU 48?

Here's a general guideline for bitterness levels based on IBU:

* 0-15 IBU: Very low bitterness, almost unnoticeable.

* 16-30 IBU: Low bitterness, balanced with malt flavors.

* 31-45 IBU: Moderate bitterness, noticeable but not overpowering.

* 46-60 IBU: High bitterness, pronounced but still balanced with other flavors.

* 61+ IBU: Very high bitterness, dominating the flavor profile.

Important Notes:

* IBU is just one measure of bitterness, and other factors like hop variety and brewing techniques can also influence perceived bitterness.

* Personal preference plays a huge role. What one person finds bitter, another might find refreshing.

* A beer with 48 IBUs might be considered "bitter" by someone who prefers low-IBU beers, but it could be considered "balanced" by someone who enjoys more bitter beers.

Ultimately, the best way to determine if a beer is "bitter" is to try it yourself!
