Have you ever wondered what makes your beer so bitter? What brings flavor to it? And what increases its shelf life? It’s the HOPS!

Those green, cone-shaped flowers of the hop plant are not only beautiful but are one of the main ingredients for making beer. You might have heard about hops and that it is use in making beers, but do you know anything else about it?

These plants come in varieties and each one affects the beer’s flavor differently.

What are hops?

The hop plant’s scientific name is “Humulus lupulus”, which means ‘wolf among weeds’. It belongs to the cannabaceae family and is called the cousin of marijuana. Hops are the female flowering part of the plant, which when dried are then used in brewing beer.

The plant is actually a perennial bine that can grow vigorously up to 30 feet. On an average a hop bine can grow several inches a day, it is grown in strings at fields called ‘hop yards’ by farmers.   

Understanding hops in beer

Today, almost all the beers brews with hops, but there was a time when beers were brewed without it. Earlier in the ninth century beers were made by three main ingredients – malted barley, yeast and water. Though at some places, the producers added herbs and spices to the beer to differentiate its taste.

In the fifteenth century, hops emerged as a fourth ingredient that added flavor, bitterness, aroma, stability, and depth to the beers. Since then, they are used widely by almost every producer.  

The role of hops in beer

The flower of the hop plant contains small glands in them, which has a sticky substance named lupulin. This substance has some essential oils and acids that are responsible for giving the beer flavor, aroma, and bitterness. The market for these flowers is categorized into two – Alpha hops and aroma hops.

Nowadays, beers can’t be even imagined without them, this natural ingredient play multiple roles –

  • Flavor

Alpha hops have a higher concentration of alpha acids which adds the bitter taste in craft beers. Malt adds sweetness to the brew and hops provide a balance with the bitterness.

Moreover, they add flavors to it too; different varieties add distinct flavors like floral, piney, spicy, citrusy, Herbal, etc. Without them, beer will taste sweet and dull which is not the classic taste.    

  • Preservation

These tiny flowers contain properties that fight against unwanted bacteria and keep the beer fresh. They act as a natural preservative and keep the flavor intact. 

  • Aroma

The aroma hops have a higher concentration of essential oils and low alpha acid in its glands. It accounts for the aroma in the beer which also differs in varieties.

  • Value

Modern beer drinkers like that of Craft beers prefer hoppier beer because it has a classic taste. In fact, it’s said, “The hoppier the beer is the more valuable it is”. It is now necessary for all beers to carry a value termed as “IBU- International Bitterness Units”. 

These units indicate the bitterness in a beer, the higher the IBU more the bitterness. However, there are other factors that contribute to the same and it depends on perception too.

How are they used in beer?

They are used in varying degrees like the IPAs have a higher concentration of hops whereas it is very low in stouts. Brewers add it after the mashing process.

They do it in stages when the brew is boiling to affect the bitterness, flavor, and aroma. Earlier hops were directly added to the cask after fermentation to preserve the beer while transportation. Now they are used at various stages for different effects.  

Kinds of Hops

There are tons of varieties of hops; each differs from the other due to their acid and essential oil concentration. Some have high alpha acid while some have high levels of essential oils; some have a balanced concentration of both of these.

If we categorize them based on geographies of origin, there are three main kinds of hops.

  • Noble

They include strains like Czech Saaz, Hallertau, Spalt and Tettnang and are rich in essential oil humulene that provides high aroma and has low alpha acids.

  • American

Hops that are quite bold, aromatic and bright with origins in the United States comes in this category. They include Centennial, Chinook and Columbus and Cascade (the most popular ones). 

They have high levels of essential oil myrcene which gives the beers citrus and pine flavors. For a taste of American hops, you can try Racer 5 IPA from the Bear Republic, ranger IPA, west coast IPA, and amber IPA.

  • English

Used in British ales, these hops low myrcene which gives space to other essential oils to provide delicate and mild flavors. When added to the beer it may enhance notes of wood, herbs, molasses, and spice. 

They include varieties like Fuggle, East Kent Golding, Pilgrim and target. To get a taste of English hops you can try UK’s St. Peter’s best bitter and quaff Abbot ale from Green King Brewery.
