Since the brewing of coffee has been mainstream, hot brewing has been the way of choice… mostly because it was pretty much the only way. However, cold brew coffee has come along and it is creating a divide in the coffee world. It is proving to be very popular and give a really great tasting coffee.
For those who believe cold brew coffee is the way to go, they may soon be able to get it at a lot of coffee shops and in K-Cup coffee forms, including establishments like Starbucks. Starbucks is currently in testing mode of the cold brew method in Boston and other coffee house chains are testing it as well.
Cold-brewed iced coffee is brewed by steeping coffee ground in room temp water for quite a few hours. After the grounds have soaked, you strain them. Those who prefer this brew state that it gives a smoother, superior flavor of coffee because it is less acidic than traditional brewing methods.
The cold-brew method takes between 12 and 24 hours, so it is not ideal for shops that need to serve coffee quickly but the new round of testing is challenging the brewing speed. Typically, many coffee places prepare their iced coffee by brewing it hot and then putting ice in it.
