Understanding IBUs : How Beer Bitterness is Measured

Ever wondered what IBUs mean when looking at a beer label? The International Bitterness Units (IBU) scale is a key measurement in brewing, but it doesn’t always mean what you think. Let’s break it down.

What Are IBUs in Beer Terms?

• IBUs measure the amount of bitter compounds (mostly from hops) in a beer.

• Higher IBUs generally mean more bitterness, but that’s not the full story.

Does Higher IBU Always Mean More Bitterness?

Not necessarily! The perceived bitterness of a beer depends on:

• Malt Balance – Sweet, malty beers (like stouts) can mask bitterness.

• Hop Variety – Some hops add bitterness, others add floral or fruity notes.

• Beer Style – A 50 IBU pilsner will taste much more bitter than a 50 IBU stout.

Common IBU Ranges by Beer Style

• Light Lagers & Wheat Beers: 5-20 IBUs (minimal bitterness)

• Pale Ales & IPAs: 30-80 IBUs (moderate to strong bitterness)

• Imperial IPAs & West Coast IPAs: 70-100 IBUs (intense bitterness)

• Stouts & Porters: 20-60 IBUs (bitterness balanced by malt sweetness)

Why IBUs Matter (and Why They Don’t)

• IBUs are useful for brewers to maintain consistency.

• For drinkers, taste perception is more important than the raw number.

• Focus on flavour balance rather than chasing high or low IBUs.

Final Thoughts

IBUs are just one piece of the puzzle. Next time you try a new beer, use IBUs as a guideline, but trust your palate! 🍻
