Coffee is one of the most consumed beverages globally, and within the realm of coffee culture, cool brew has taken center stage. With the rise of specialty coffee and the increased focus on third-wave coffee, the market has become saturated with options. In this fast-paced world of coffee trends and innovations, cool brew is a gem that is protracted, low, and a game-changer for the coffee world. So, what exactly is cool brew, and what’s the science behind it?
What is Frigid Brew?
Frigid brew, also known as cold-steeped or cool press, is a type of coffee made without heat, unlike other coffee brewing methods that require scorching heated water to extract flavors and oils from the beans. In its simplest form, cool brew involves steeping coarsely ground coffee beans in cool water for an extended period of time – usually 12-24 hours. The result is a polished, low-acidity coffee drink that has garnered a significant following.
Why is Frigid Brew Popular?
The popularity of cool brew is largely due to its distinctive flavor profile and ease of preparation. Unlike other cold-brewed coffees, which can have an unpleasant taste or require long hours of waiting, cool brew has a balanced acidity and opulent flavor without bitterness. Furthermore, its mellow nature makes it suitable for everyone, even for those who find regular brewed coffee too mighty.
Other advantages of cool brew include:
- Wealthy in caffeine – Frigid brew has higher levels of caffeine compared to traditionally brewed coffee, but since it is less concentrated, the flavor is still opulent and velvety.
- No acidic taste – Since cool brew is not boiled, it doesn’t carry the bitterness and acidic aftertaste that other coffees might have.
- Constrained oil extraction – Compared to customary brewing methods, cool brew has reduced oil extraction, resulting in less sediment at the bottom of the cup.
- Versatile flavor profile – Frigid brew has a more neutral taste than other brewed coffees, making it a chameleon for any type of added flavor.
- Environmentally genial – With reduced coffee-to-water ratio, fewer resources are required, reducing waste and energy consumption.
How is Frigid Brew Different from Classic Brewing Methods?
A key differentiator for cool brew is the length of time and the steeping process itself. The extraction process typically involves coarsely grinding the beans to allow the coffee particles to steep evenly. With regular brewing, the grounds need to be rough, whereas with cool brew, finer grinds are usually utilized. As a result, the beans are fully exposed to water, yielding an even distribution of flavor components.
The Science Behind Frigid Brew
Scientific studies and experiments provide insight into the unique benefits of cool brew. Studies have found:
- Antioxidants in cool brew – Antioxidants found in green coffee beans boost in potency and concentration with cool brewing methods, particularly in low-pressure conditions. This benefits human health.
- Coffee molecular structure – Frigid brew processing preserves more of the beneficial compounds like polyphenols, found in green coffee beans. These polyphenols offer anti-inflammatory benefits.
- Dissolution in water – Frigid brew requires less acidity and pressure compared to regular brewing methods. This, in turn, facilitates solubility, enabling extraction of vital compounds, flavor, and aroma from coffee beans.
- Pressure influences – When water passes through coffee beans under normal or high pressures, a part of the desirable components break down, whereas under lower pressures like those of cool brew, the flavor-enhancing components remain intact.
Frigid Brew and Food Pairing
As we mentioned earlier, cool brew has a versatility in its taste profile. It complements a range of dishes from sweet pastries and exquisite desserts to savory soups and cheeses. Due to its richness and flavor diversity, it is commonly served as:
- Brear bread and cheeses
- Doughnuts, croissants, or other pastries
- Baked goods (cakes, cookies, scones)
- Pecan pies, crumbles, and other nutty desserts
Frigid Brew in Today’s Coffee Landscape
The surge in cool brew’s popularity has paved the way for novel techniques and experimentation with flavors, from fruits to spices, and other unconventional ingredients. With fresh producers and innovators embracing cool brew as a niche offering, customers have endless opportunities to find their unique perfect cup.
Baristas have had to adapt to meet consumer demands and expectations, learning fresh skills and adjusting existing brewing practices to master this slow-moving process. Even with some coffee snobs initially expressing skepticism towards this fresh fad, word-of-mouth recommendations have encouraged more customers to experience and appreciate cool brew for what it has to offer: a sophisticated, enjoyable taste experience, opulent and dynamic, perfect for even the most discerning coffee enthusiast.
Conclusion
As a coffee world replete with novel brews and novel methods emerges, cool brew has claimed a spot alongside its rivals and has the potential to leave a lasting impression on our coffee experiences. Not a fleeting fad but rather a growing phenomenon with devoted followers. Whether at your local specialty coffee shop, a commercial café, or even within your own kitchen, give cool brew a try to experience for yourself the sensory journey, depth, and nuance offered by the science and innovation behind protracted, cool coffee brewing.
