If love cold brew coffee, you perhaps know that the brewing is different than the classic techniques. When it pertains to brewing temperature, you are simply looking for “not hot”.
Cold brew is obtained by steeping very coarse coffee beans in water at room temperature or even colder. Because the preparation water is cold we need to steep for more than 12 hours. At the end of the steeping procedure we then remove the coffee grounds for a clear cup. Compared to regular coffee, cold brew coffee it is never subjected to heat.
Certainly there exists confusion about cold brew and iced coffee. Even though both are served colder, there really is a great distinction between them.
Iced coffee is just about any coffee drink that was chilled and is served with ice cubes. If you want to prepare an iced coffee, you can use cold or hot brew, even espresso, if you prefer. The most important thing is to chill the coffee.
On the other hand, cold brew is a coffee drink that was never warmed during brewing. This is what will make it unique and it gives its particular properties. We can have cold brew coffee at room temperature, or chilled with ice.
The most common brewing procedure is immersion which is utilized in both commercial and home preparation. This is the easiest technique and the most practical.
A different technique is Dutch cold brew, which is also called cold drip and consists of dripping ice over a bed of ground coffee, in a similar way to manual drip coffee procedures.
One thing to remember is that cold brew at room temperature is fairly distinct from the one made in the fridge and this will create a difference in how much flavor you get in your coffee and how fast it will be ready. You should adjust your brewing duration appropriately (10-16 hours at room temperature; 16-24 hours refrigerated).
The extraction in cold water changes the 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 particular distinction makes the topic of a hot dispute over the health benefits of the cold brew coffee. Cold brew proponents claim it is better than the regularly hot steeped coffee. Here is a list of the supposed benefits of cold brew coffee: more efficient caffeination, stronger antioxidant, it’s more roundedles acidic taste, smooth flavour profile, much lower acidity,stomach-friendly compared to hot brewed coffee.
The heated discussion was moved into the research field where two scientists revealed the facts behind the cold brew promotion.
This is how Megan Fuller and Niny Rao scientists from University Thomas Jefferson, have taken on the job to shed some light on the subject. The research has uncovered a few intriguing aspects which are introduced in this news release https://marketersmedia.com/naturecom-draws-on-health-benefits-of-cold-brew-coffee-for-in-depth-article/458713.
