What exactly is bitterness (IBU)?

The bitter taste is a strangely appealing signature point for Craft Beer enthusiasts. The bitter taste of beer provides a refreshing sensation with each sip of cold beer, and it is also the most noticeable difference between Craft Beer and Regular Beer.

So, do you know what causes the bitter taste of beer? And why do different beers have varying levels of bitterness?

What exactly is bitterness (IBU)?

Bitterness is determined by the amount of Hops used in the brewing process, which is abbreviated as IBU (International Bitterness Unit). The more hops used, the stronger the bitterness of the beer.

The IBU scale demonstrates that each beer line has a very different hops ratio:

- Lager Pilsner: 8-26 (mild, almost not bitter)

- Pale Ale: 30-50 (mildly bitter)

- IPA: 40-120 (very bitter)

- Porter:18-50 (from not bitter to very bitter)

- Stout: (from not bitter to very bitter)



The role of hops in craft beer production

Hops are an essential ingredient in crafting the distinct flavor of craft beer. It contributes to the formation of a bitter taste and enhances the typical flavor of beer. Furthermore, it improves the stability of the microbiome in beer and stabilizes the taste of beer.

Hops have the ability to keep beer foam (created by the CO2 process) longer, resulting in a satisfying feeling and a sense of thickness in the mouth when drinking beer with a smooth foam layer.

People frequently use the bitter and aromatic essential oils found in the pistils of unpollinated female flowers to make beer because they have their own value in the production of premium craft beer.
