Cold brew coffee is one of the hottest trend in coffee, and it is here to stay.
But the idea of a cold cup of coffee could send people running for the hills if they are yet to try it. If done right, however, it could well result in one of the best home brewed coffees you have ever had – and there is opportunity to heat it up, too.
Cold brew coffee is simply the method of brewing coffee in cold water rather than near boiling.
It is not to be confused with iced coffee, where espresso coffee is served over ice with the addition of milk and syrups.
But why brew the coffee in cold water? Well, first of all, the lack of heat treats the grounds better. Using hot water can scald the grounds, resulting in a slightly burnt and overdone taste. However, steeping in cold water for 24 hours or more allows the flavour to be captured without the negative aspects. This is what the ‘immersion’ part is.
This results in a concentrated coffee solution which you can then add extra water, milk and sugar to, as you would have an ordinary coffee. You can even heat it up in the microwave!
It is a good idea to have a coffee grinder to hand if you have speciality equipment such as this. A consistent grind is vital for a consistent good taste.
But the good news is that you don’t need a highly complicated, expensive one. It is best to stick with a coarse grind, which will make the filtration process easier and your coffee taste far less bitter.
Grinding your beans very fine, which takes longer, can heat up the grounds, which can negatively affect your cup as they could become burnt – not what you want for such a sensitive method.
A manual grinder at the budget end of the scale would probably be just fine as every grind wouldn’t have to be perfect, but invest in something more precise if you will be trying various methods.
