Cold brew coffee is a phrase that we can easily hear of in daily life. Today small cartons of cold brew coffee are sold in supermarkets and chain stores globally. So what is cold brew coffee? Does it make the coffee tastier and better?
In this post, VINUT will introduce to you the description as well as the health benefits of the cold brew coffee
What is cold brew coffee?
At first, we shouldn’t be confused cold brew coffee with iced coffee. What makes cold brew coffee so delicious is the amount of time it takes to brew. Brewing is the process during which ground coffee and water come into contact. Whether we brew coffee using boiling hot or cold water – it is still called brewing. Regarding cold brew, it is different from brewed coffee in 3 ways: it brews cold, brews for at least 14 hours and is not bitter.
Technically, cold brew coffee is made by steeping coffee in water from 14 to 24 hours at cold or ambient temperature. This slow, low temperature makes cold brew taste very different from hot brewing the same type of coffee beans.
Cold brew vs Iced Coffee
Iced coffee is exact as what its name which is brewed coffee served over ice. It is prepared either by brewing coffee normally and then serving it over ice or in cold milk. Iced coffee can also be sweetened with pre-dissolved sugar in water.
Cold brew coffee is about the way that ground coffee is steeped in cold water for amount of hours. The longer the coffee sits, the stronger the flavor. Then you can use it with ice as wish.
Where does Cold Brew Coffee Originate?
It’s said that Dutch trading ships brought coffee to Kyoto, Japan, resulting in the ancient but modern practice of Kyoto style coffee. This style of coffee is made by letting water to slowly drip over coffee grounds inside glass towers. People found that a drip process extracted more flavor. This brewing method is also known as Kyoto-style coffee.
Over time, the cold brew method has improved and become an art. Instead of just soaking the coffee in cold water for hours, the captured coffee is cold brewed by letting each drop of water drip through the powdered coffee layer during the brewing process.
Benefits of Cold brew coffee
Technically, cold brew coffee is also coffee, so it will have the same health benefits as regular coffee, including:
1. Contains Antioxidants
Researchers found that antioxidant content of cold and hot brews coffee was about the same. The acidity of any brew made from light roasted coffee is generally higher than that of dark roasts, while light-roasted cold brew was not less acidic than a brew of the same beans made with hot water.
2. May boost Metabolism
Cold brew has plenty of caffeine which has been proven to boost your body’s metabolic rate by increasing how quickly our bodies burn fat. The higher your metabolic rate, the more calories you burn when you rest.
3. May be Easier to Digest
Cold brew and regular coffee have similar acidity levels, around 5–6 on the pH scale (this can vary), but some studies have found cold brew to be slightly less acidic than hot brew coffee.
4. May Lower the Risk of Heart Disease
Drinking 3 to 5 cups of coffee (15 to 25 ounces) daily may lower your risk of heart disease by up to 15% compared to people who don’t drink coffee. In addition, cold brew contains heart-healthy compounds, including magnesium, antioxidants, and anti-inflammatory agents.
5. Boost Focus
Cold brew coffee contains a slightly elevated amount of caffeine, which has been shown to improve the focus and attentiveness of its respondents. Caffeine is a stimulant that binds to adenosine receptors (a neurotransmitter that increases sleepiness throughout the day). This action encourages the absorption of dopamine, which in turn, reduces the degree to which you get sleepy.
6. May Reduces Diabetes Risk
Research is showing that drinking more coffee may help decrease the risk of developing type 2 diabetes. A 2009 study of about 40,011 participants who consumed at least three cups (or up to five cups) of regular coffee or tea daily found that they were 42% less likely to have type 2 diabetes. Another study of nearly 1,000 people that those who drink one and a half cups of cold brew coffee are more than 40% less likely to contract type-2 diabetes.
