If love cold brew coffee,you most probably recognize that the brewing science is really different than the classic hot brewing methods. When it refers to water temperature, you’re simply looking for “room temperature.”
Cold brew is brewed by steeping coarse coffee beans in room temperature water or colder. Due to the fact that the preparation water is cold we ideally want to steep for over 12 hours. At the end of the infusing time we then filter out the coffee grounds for a clean cup. Compared with ordinary coffee, cold brew coffee it is not exposed to temperatures over room temperatures.
Generally there exists confusion about cold brew vs. iced coffee. Although technically they are both served cold,there actually is a substantial difference between the two.
Iced coffee is any sort of coffee beverage that was cooled and is served with ice. In order to prepare an iced coffee, you can use cold or hot brew, even espresso, if you wish. The most important is to cool the coffee beverage.
On the contrary, cold brew is a coffee drink that was never warmed at the time of brewing. This is what makes it unique and it gives its extraordinary properties. We can serve cold brew coffee at room temperature,or cooled with ice.
The most popular brewing method is immersion that is utilized in both home and commercial preparation. This is the easiest solution and the most efficient.
Another cold brew method is Dutch cold brew, or cold drip and implies dropping ice cold water over ground coffee, in the same way to hot coffee techniques.
One point to remember is that coffee brewed at room temperature is considerably distinct from the one steeped in the cold storage and this will produce a distinction in how much flavor you get in your coffee and how fast it will be ready. You need to fine-tune your brewing duration as necessary (10-16 hours at room temperature; 16-24 hours refrigerated).
The extraction in cold water alters 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 heated dispute over the health benefits of the cold brew coffee. Cold brew promoters claim it is better than your typical boiled coffee. Here is a list of the supposed positive aspects of cold brew coffee:
- Smooth flavour, low acid.
- Strong and prolonged caffeine kick.
- It’s more mellow and less acidic.
- Stomach-friendly compared to hot brewed coffee.
- Better antioxidant.
The heated debate was moved into the science field where two scientists revealed the facts behind the cold brew marketing promotion.
This is how the investigators at the Thomas Jefferson University, in Philadelphia have taken up the task to shed some light on the matter. The research has divulged some intriguing facts which are presented in this -.
