How To Make The Best Cold Brew Coffee In A Mason Jar At Home

Cold brew coffee is sometimes confused with iced coffee, which is not the same thing at all.

Iced coffee is a chilled beverage served with ice. It can be brewed cold but doesn’t have to be.

Making Cold Brew Coffee

Making the cold brew coffee involves steeping the coffee grounds in water for at least 12 hours, then filter the grounds out for a very concentrated essence. That is something radically different from the process of brewing coffee in the espresso machine.

This java essence is then diluted with water or milk and can be served in many different ways, both hot and cold. The cold-brewed is known for having a less acidic and more mellow taste than coffee from the office coffee maker.

If you’re getting cold brew pretty often in Starbucks or Dunkin Donuts, it will save you both money and time if you start making your own at home. No more need to stand in a queue or shell out your hard-earned money.

Not only is it much cheaper, but it’s also a lot more customizable because you can make it suit your tastes. You can experiment with different grounds and try to find your best roast. You can test different grounds-to-water ratios and try out other sweeteners. There are so many options to test!

You don’t have to be limited to only a handful of set options off a menu because you can make whatever you want yourself. It also means you know exactly what is going into your brain juice and that it is not watered down.

Here’s how to make a fresh batch in the comfort of your own home to have whenever you want. One batch of this can last you a couple of weeks, and depend on your needs, you can half or double the recipe as you would like. This recipe will be for 1 gallon.

What Do You Need To Make A Cold Brew?

Here are the things you will need, all of which you probably already have lying around.

  • First up, a container, preferably glass, that can hold 1 gallon of liquid. If you are halving or doubling this recipe, your container size with change accordingly. Mason jar is an excellent option for this.
  • Next, you will need a Burr grinder specifically because of the consistent grind it can give instead of a blade grinder.
  • You will also need a filter. You can use a strainer bag specifically designed for this purpose, or you can use a cheesecloth, a t-shirt, or anything else you can think of.
  • Lastly, of course, you need the beans. We will be using whole beans for the best taste and freshness, but you can also use pre-ground coffee if you’re in a hurry.

Some recipes require using French Press. If my readers are interested, I will also describe the French Press method.
