The time it takes to make cold drip coffee depends on the method you use. The traditional method using a glass or ceramic filter can take anywhere from 12 hours to 24 hours. However, there are now faster methods available that can produce a cup of cold drip coffee in as little as four hours. Cold drip coffee is made by slowly dripping cold water over coarsely ground coffee beans. The water and coffee mixture drips into a carafe or other container, and the final product is a concentrate that can be diluted with water or milk. The main advantage of cold drip coffee is that it doesn't require heat, which means that the flavor of the beans is not altered by brewing. This results in a smooth, rich, and flavorful cup of coffee. It also has a lower acidity than hot-brewed coffee, making it easier on the stomach. If you're interested in trying cold drip coffee, there are a few things you'll need. First, you'll need a grinder to coarsely grind your beans. Next, you'll need a filter - either a glass or ceramic filter. Finally, you'll need a slow dripper, which is basically just a device that allows the water to drip slowly over the beans. Once you have all of your supplies, making cold drip coffee is relatively simple. First, add your beans to the filter. Then, slowly pour cold water over the beans, being careful not to disturb the grounds. Allow the coffee to drip for 12-24 hours, depending on your desired strength. When it's finished dripping, dilute the concentrate with water or milk to taste. Cold drip coffee can be stored in the fridge for up to two weeks, so feel free to make a big batch and enjoy it all week long!
