If like cold brew,you perhaps know that the brewing science is really different than the typical hot brewing methods. When it comes to coffee brewing temperature, you’re only looking for “not hot.”
Cold brew is obtained by submerging coarse ground coffee beans in water at room temperature or colder. Since the preparation water is cold we want to steep for over 12 hours. At the end of the soaking procedure we then remove the coffee grounds for a clean cup. Unlike regular coffee, cold brew is actually not exposed to high temperatures.
Generally there is confusion concerning cold brew versus iced coffee. Although actually both are served cold,there is a great difference when comparing them.
Iced coffee is any sort of coffee that was chilled and is served with ice. In order to prepare an iced coffee, you can use cold brew or hot brew, even espresso, if you want. The most important thing is to cool the coffee beverage.
On the contrary, cold brew is a coffee that was never warmed during the course of preparation. This is what will make it different and it offers its particular properties. We can have cold brew coffee chilled with ice cubes.
The most popular preparation procedure is immersion that is utilized in both coffee shop and home brewing. This is the easiest technique and the most convenient.
Another approach is Dutch cold brew, which is also called cold drip and consists of dripping ice over ground coffee beans, in the same way to hot-brew coffee procedures.
One thing to remember is that cold brew coffee at room temperature is fairly distinct from the one brewed in the fridge and this will produce a difference in how much flavor you get in your coffee and how fast it will be ready. You should calibrate your brew times properly (10-16 hours at room temperature; 16-24 hours refrigerated).
The extraction in cold water modifies the chemical composition of the cold brew coffee, and we get in turn a cup of joe that is a totally different beverage from your regular drip coffee, or espresso.
This specific difference became the topic of a hot debate over the health benefits of the cold brew. cold brew coffee proponents claim it is healthier than your typical hot brewed coffee. Here is a list of the proposed positive aspects of cold brew coffee:
- Smooth flavour profile, low acid.
- Better caffeine kick.
- It’s smoother and less acidic.
- Stomach-friendly compared to hot brewed coffee.
- Better antioxidant.
The heated up dialogue was taken into the science field where two scientists uncovered the truth behind the cold brew promotion.
This is how the researchers at the Thomas Jefferson University, in Philadelphia have taken on the project to shed some light on the matter. The research has uncovered many intriguing aspects which are shown in this press release.
