Hops, the iconic ingredient in beer, have undergone significant changes thanks to extensive research efforts. The complexities of hops and their impact on beer are still not fully understood, which is why research in this area is ongoing. While hops used to be primarily recognized for their antibacterial properties, they are now predominantly valued for the aroma, bitterness, and flavor they impart to beer. P.R. Ashurst explains that hops used in brewing today have been developed through continuous selection of cultivated plants over the past century.
With approximately 267 different varieties, hops have come a long way from growing wild. In the past, they were simply considered edible plants with some medicinal value. However, in the craft beer industry, hops are now used to create unique flavors and aromas that appeal to beer enthusiasts. As consumer tastes change, the demand for new and exciting flavors and aromas increases, and the industry must respond by conducting research.
Developing new hop varieties is a recognized way to achieve these unique characteristics in beer. Researchers focus on creating hops with increased yield or intensified compounds to enhance flavors and aromas. This ongoing research is crucial for keeping the craft beer industry vibrant and responsive to consumer demands. Breweries will continually introduce new hop plants into their repertoire as a result of this research. Additionally, improved growing practices and cone processing techniques have led to higher yields and reduced hop production costs.
It’s interesting to reflect on the changes that have occurred in the beer industry over time, from brewing styles and practices to regulations and consumer preferences. Back in 1978, Jimmy Carter played a pivotal role in launching the craft beer industry. As consumers, we all want a high-quality beer with excellent flavor, aroma, and consistency at an affordable price. However, achieving this goal is not as simple as it seems. For example, who would have thought that research on beer foam and the patterns it creates in the glass while being consumed would be important? Yet, foam and lacing are essential indicators of a quality beer, and they are influenced by the use of hops.
Change, whether initiated through plant research or marketing research, always carries some level of risk. Schlitz, a famous beer brand known for making Milwaukee famous, learned this the hard way when they modified their recipe and production techniques without conducting proper research. In this article, we are primarily focused on hops research because it is the most frequently discussed ingredient in beer, and consumers always notice the flavors and aromas that hops contribute.
Although the primary use of hops today is in beer production, they have also been found to have beneficial properties for medicinal products, food enhancements, and personal care products. However, beer production still accounts for 97% of global hops usage. It’s worth noting that the United States produces 66% of the world’s hops, highlighting the importance of research efforts in this country. Interestingly, China is a top beer producer as well.
Throughout history, hops have played a crucial role in the preservation and commercialization of beer. In the 15th century, hopped beer became a valuable commodity for trade, thanks to the antibacterial properties and bittering activity of hops. It wasn’t until much later that brewers discovered the true secret behind beer production: yeast. In 1680, yeast was observed in beer using a microscope, but it took another 200 years, thanks to the research conducted by Louis Pasteur, to fully understand the role of yeast in brewing.
America’s involvement in the hop industry can be traced back to early European immigrants, particularly those from Germany. These immigrants brought seedlings from various wild hop plant varieties that had been cultivated in Europe for centuries. It was discovered that the climates and soil conditions in Washington, Idaho, Oregon, and California were perfect for growing hops. Even today, many universities continue to explore regional opportunities to contribute to the hop industry.
In 1416, the English began using hops as an antibacterial preservative in beer, and a century later, the Bavarian government made hops one of the three allowable ingredients in beer (yeast had not been discovered yet). The early research behind the prominence of hops in brewing remains largely unknown. However, today’s research covers a wide range of topics, from breeding and growing hops to understanding their plant chemistry and how different compounds impact beer quality. Researchers aim to enhance or suppress specific properties of hops to create new beers with distinct characteristics.
While my focus in this article has been on beer, it’s important to note that hops have also found uses in various other products. They are used in soaps, shampoos, deodorants, lotions, and skincare products due to their calming and antibacterial properties. Hops are even used as food spices in restaurants and can be brewed into a delicious tea using the Tattnang Hop variety. Additionally, there is ongoing research into the potential cancer-fighting properties of hop resins found in select hop varieties.
Hops also offer benefits in animal feeds by preserving them and providing supplementary nutrients. There is still much research to be done in all these areas, and ongoing studies will continue to expand our understanding of hops and their versatile applications.
In conclusion, the research conducted on hops plays a vital role in the beer industry’s ability to meet consumer demands for new and exciting flavors and aromas. The complexities of hops and their impact on beer are still being explored, making continued research crucial for the craft beer industry’s growth and innovation.
