Cold brew coffee is easy to make at home although it takes much longer to prepare it than hot coffee. You don't need any special equipment beyond, just a large jug for making the coffee and a strainer. Cold brew coffee differs from iced coffee on its brewing method and its taste. It is made by steeping more-coarsely ground coffee in the cool water for at least 12h. During that time the coffee slowly infuses into the water, creating a strong, concentrated but incredible smooth and almost sweet-tasting brew. The brew coffee tastes also much less bitter and less sour. The cold brew coffee is perfect for iced coffee. To drink the finished brew, use a ratio of 1:1.
To make cold brew coffee infused with spices: previously to adding water to the coffee grounds: boil the water, add 1 cinnamons stick, 6-8 green cardamoms, 5 cloves and let it simmer for 15 minutes. Then strain and cool it
