The name is tossed around in brew lover conversation and found in beer descriptions at Flagstaff breweries, but what exactly are hops? What are the experts talking about? And why does it matter to your beer drinking experience?
You have questions. We have answers.
So, What Are Hops Anyway?
Hops are the flower clusters from the hop plant Humulus lupulus, a perennial plant that is a member of the hemp family.
What does this have to do with beer? It’s one of the four basic ingredients in beer brewing (the other three being grain, yeast, and water). Brewmasters only use the flower of this hop plant for beer brewing in the shape of compressed pellets.
Why Brew With Hops?
The flower of this hop plant contains an essential oil with a very bitter flavor. This counters the sweetness from the malt in beer, thus creating a more balance beer. It also acts as a beer preservative. Brewmasters play with the ratio of bitterness and sweet maltiness in their brew by:
- Adjusting the type of hops used
- Timing when the hops are added to the wort
- Adjusting the time they’re boiled
Types of Hops You Should Know
Generally, hops are divided into two broad categories: aroma and bittering.
Bittering hops have high levels of alpha acids and high levels of bitterness
