What is the difference between cold brew and iced coffee?
While iced coffee is brewed hot and poured over ice, cold brew coffee is ground coffee that has been steeped in cold water for many hours then strained before serving.
Iced coffee, like an iced latte, is a very quick and familiar process. You brew a hot shot of espresso then pour it over ice before adding milk. This rapid extraction of flavours can cause iced coffee to become quite bitter.
Cold brew, on the other hand, can take up to 24 hours to make as it is a gentle process of infusing ground coffee with water. This process usually creates stronger, yet sweeter tasting coffee.
How to brew cold brew at home
Although there are a few ways to make cold brew coffee, there is a basic formula: coffee grounds, cold water and brewing overnight. Here’s our step-by-step guide to making cold brew coffee at home with a cafetiere.
Either buy course, pre-ground coffee or use a coffee bean grinder to make your own. Make sure to set your coffee bean grinder to the coarsest setting. If the coffee is too fine, then it can make filtering much harder.
Take a large cafetiere and fill it to a rough 1:8 coffee-to-cold-water ratio. Stir gently then cover the cafetiere with a lid or some clingfilm. Leave for 24 hours.
Once brewed, strain the coffee. You can do this by using the cafetiere’s plunger. Pour the coffee through a sieve lined with coffee filter paper into a jug. Discard the coffee grounds in the cafetiere, ideally into a compost if you have one.
You may need to strain the cold brew a few times until you get a clear liquid and remove any murky residue.
Once the cold brew is clear and sediment-free, serve over ice. Enjoy it black or with milk if you prefer. Cover the jug and place in the fridge.
