Hops In Beer: Necessary Or Overrated?

Beer is typically made with four main ingredients: water, malt, hops, and yeast. However, hops are not a necessary ingredient. In fact, there are several types of beers that don't use hops, such as gruit, which uses herbs and spices like bog myrtle, yarrow, heather, or juniper to add flavour.

Hops are the flowers, or cones, of a plant called Humulus lupulus, which is a member of the Cannabaceae family (which also includes cannabis). They add bitterness, flavour, and aroma to beer, and also act as a preservative, giving the beer a longer shelf life.

Hops are not essential to beer

Before hops, beer was flavoured and preserved with gruit, a combination of herbs and spices such as heather and mugwort. The first recorded use of hops in brewing was in the 9th century, though it is likely they were used even earlier. For example, there are records of hop cultivation from around 600 AD in what is now Belgium.

Today, there are still beer styles that don't use hops at all, such as gruit, which relies on herbs and spices for flavour. Brewers may also choose to make beer without hops as an interesting experiment or to create a certain profile, such as a strong malty/caramel flavour.

Hops are cone-shaped flowers of the hop plant, which is a member of the Cannabaceae family (which also includes cannabis). They are used in brewing beer for two main reasons: as a bittering agent and as a flavouring/aroma agent. However, their use is not mandatory and beer can certainly be made without them.

Hops add bitterness to beer

Hops are one of the four essential ingredients in beer, alongside barley, yeast, and water. They are the flowers of the female hops plant, Humulus lupulus, a cousin of the cannabis plant. Hops contain acids and oils that impart bitterness, flavour, and stability to the finished beer.

Hops are typically added to the boil stage of brewing, as it takes around an hour to unleash the "alpha" acids that bitter and balance the sweetness of the malt. The longer the hops are boiled, the more bitterness they impart to the beer. Hops added at the start of the boil process contribute to the beer's bitterness, while hops added near the middle to the end contribute more flavour and less bitterness. Hops added at the very end of the boil contribute primarily to the beer's aroma.

The bitterness of a beer can be calculated by looking at the alpha acid of the hops variety and the length of the boil time to determine the IBU (International Bittering Units). However, the perceived bitterness of a beer also depends on other factors such as the amount of malt and ABV. A beer with higher IBUs may not necessarily taste more bitter than a beer with lower IBUs if it has more malts and a higher ABV to balance out the bitterness.

While hops are commonly associated with bitterness, they also have other important roles in brewing beer. Hops can add a range of flavours to beer, such as fruit, spice, herb, mint, and floral flavours. They also have preservative qualities, helping to extend the shelf life of beer. Additionally, hops contribute to head retention by coating the CO2 gas as it rises to the top, preventing the bubbles from popping immediately.

Hops are flowers of the Humulus lupulus plant

The female flowers of the Humulus lupulus plant are cone-shaped and are also called seed cones or strobiles. They are packed with essential oils and alpha acids, which are released during the boiling process of brewing beer. The alpha acids contribute to the bitterness of the beer, balancing out the sweetness of the malt. The essential oils in the hops help to create and maintain the foam in the beer.

The Humulus lupulus plant can grow up to 33 feet (10 meters) tall and has a lifespan of up to 20 years. It is triggered to flower during the longer summer days, usually around July or August in the Northern Hemisphere. The plant is a fast-growing, climbing vine that can consume and suffocate trees if left unchecked.

The use of hops in brewing beer dates back to the 9th century, and possibly even earlier. Hops add bitterness, flavour, aroma, and preservative qualities to the beer. The preservative qualities of hops were especially important in the creation of India Pale Ale (IPA), which was brewed to survive the long journey from Britain to the British Empire in the east.

Hops help preserve beer

Hops are an essential ingredient in beer, alongside barley, yeast, and water. They are the cone-shaped flowers of the female hops plant, Humulus lupulus, a cousin of the cannabis plant. Hops contain acids and oils that impart bitterness, flavour, and stability to the finished beer.

Hops have preservative qualities, giving beer a longer shelf life. This is why IPAs were invented. IPA stands for India Pale Ale, a solution to get beer to the British Empire in the east. India was too hot for brewing beer, so a strong, heavily hopped beer was needed to survive the six-month journey from Britain. In the 1780s, a heavily hopped beer called October ale did the trick. Adding more hops helped preserve the beer long enough for the long journey.

The hops in IPAs were intended to preserve the beer for long sea voyages, as hops have some antimicrobial properties. The type of spoilage that 18th-century British merchants were trying to prevent was bacterial infection or some type of souring or spoilage of the beer.

Hops added at the start of the boil process contribute to the beer's bitterness, while those added near the middle to the end contribute more to flavour and aroma. Hops can add fruit, spice, herb, mint, floral, and even grassy flavours.

Beers without hops are called 'gruits'

Hops are a key ingredient in beer, adding flavour and bitterness to balance out the sweetness of malt. However, some brewers are starting to question whether hops are necessary. Beers without hops are called gruits. Gruit beer is an ancient style of beer that predates beers with hops in them.

Gruit beers rely on herbs and spices to give flavour. In medieval times, gruit beer was widely consumed before hops were introduced. Nowadays, a hopless beer is hard to come by in grocery stores and the majority of breweries, but some modern brewers in mainland USA and Europe are revisiting these ancient brewing methods, creating otherworldly beers that offer complex, intriguing flavour profiles.

Some examples of gruit beers include Marigold from Scratch Brewing Company, Kvasir from Dogfish Head Brewing Company, and Posca Rustica from Brasserie Dupont.
