We all love asking for more, double patty, double fry, double the returns. Well, did you know you could get a doubly strong coffee? Yes, it’s true. Confused? Well, you won’t be as you read this article. So what is a double brewing coffee?

A double brewed coffee is regular coffee brewed again with more coffee. In other words, you use coffee instead of water to “re-brew” your previously prepared coffee which results in distinctly strong coffee.

By reading this article, you will find out everything about double brewed coffee, how to make double brewed coffee, and all the pros and cons.

What is Double Brewed Coffee?

Usually, a nice cup of coffee should help jumpstart your day (or night). Many times though, it doesn’t. So to bolster your energy levels, you make a double brewed coffee.

A double brewed coffee is regular coffee brewed again with more coffee. In other words, you use coffee instead of water to “re-brew” your previously prepared coffee.

Not many know about this kind of coffee. It is considered to be an acquired taste, and that taste is distinctly strong.

Also, the before mentioned method is not the only way to make a double brewed cup of coffee. You can also make it by adding twice as much coffee grounds and water. Simple, right?

How to Make Double Brewed Coffee?

When making the first batch of coffee, you’re free to choose your favorite coffee-making method. However, I suggest using a French Press the second time asking.

So here’s what you’ll need before you start:

Steps to Make Double Brewed Coffee

  1. Add your freshly ground coffee into the drip machine. For the right measurements, follow the coffee and milk golden ratio of 1:15 (1g of coffee every 15ml of water).
  2. Heat the water at 200 ℉ for optimal extraction of coffee.
  3. Once the first batch is done, put it aside and start with the second brew.
  4. In your French Press, add the same amount of freshly ground coffee. Now you can pour the first batch of coffee and leave it for 3-4 minutes to saturate.
  5. Once the waiting time is up, press the plunger to give your drink a double dose of coffee.
  6. Pour into a cup and enjoy.

As you imagine yourself enjoying a freshly brewed cup of coffee, you may wonder if this is all really worth it.

That’s what the next section will help you decide.

The Pros and Cons of Double Brewed Coffee

Brewed Coffee

There’s a debate on whether brewing coffee with coffee is a good idea or not. Some say it’s a terrible idea, and you should use it as a last resort of sorts, while others love the robust taste that greets their taste buds.

So, the best way forward is to look at the prospects and consequences of having double brewed coffee.


  • More Energy Through Higher Caffeine Concentration

Maybe you’re not being refreshed by your coffee anymore. Or you need a booster to help you push through the final stages of a monumental task. That’s a call for more caffeine.

Naturally, a double brewed cup of coffee is bound to have the extra caffeine you need.

This could help you overcome any caffeine tolerance your body has developed throughout your normal coffee consumption routine. Of course, too much caffeine is not advisable, so proceed with caution.

  • Works Great for Iced Coffee Lovers

You want to enjoy a strong cup of iced coffee, but you end up getting a diluted mix. You pour the coffee in, the ice melts, and the resulting mix is a weak and watery coffee.

However, with the double brew, you can lay aside the fear of losing any taste. Your double brew will ensure that the flavor of the coffee will exert its dominance over your drink.

Iced Coffee


  • Requires Your Constant Attention

Making a double brew coffee is not something you want to do every day. Unless you brew this coffee with diligent attention, it’s bound to fail.

For example, you’re required to pay attention to the temperature while you make the coffee. Since you’re using two batches of coffee, there’s a high chance of burning.

  • You Need More Equipment

Having just one way of brewing will not suffice. You can make the first batch of coffee through your preferred style. However, the second brew will require another way to be made.

Coffee makers are commonly made to handle only water. Adding coffee to the mix will definitely cause your machine to malfunction. Hence, you need more stuff to help you make a double brewed coffee.

Other Ways to Make Double Brewed Coffee

In the beginning, I mentioned another way of making a double brew. That is, you add twice the amount of coffee grounds and water. If you’re an iced coffee kind of person, I can show you how to brew one of those too.

Here’s a step-by-step guide for both methods.

Making Double Brewed Coffee with More Coffee Grounds

  1. Add your filtered water to boil (ideally at 200 ℉).
  2. Increase the number of coffee grounds. This means that you now have a 2:15 coffee and water ratio. So 2 grams of coffee for every 15ml of water.
  3. Allow the coffee and water to steep for 2-4 minutes.
  4. Enjoy your drink!

How to Make Double Brewed Iced Coffee

For this special caffeinated concoction, you need:

  • Filtered water
  • Your favorite brewing method
  • Your favorite coffee beans
  • Ice cubes in a glass to serve

To brew the coffee, you can choose whichever method you prefer.

You can go the “adding twice as many coffee grounds” route or go by the first method mentioned in the article by brewing coffee in two separate batches, using two different processes.

Once you have your coffee ready, let it cool down a bit before pouring it into a glass filled with ice cubes.

Enjoy your much-needed respite on a hot day.

What Are The Best Coffee Beans For a Double Brew Coffee?

The Best Coffee Beans

What kind of beans would you usually use for a double brew? It all depends on your preference. If you love using dark roasted coffee beans, stick to those. If you’re a medium roasted coffee fan, then by all means, keep using what you love.

Experiment with different roasted beans to discover how each of those tastes. Maybe you’ll find a combination you love.

All Possible Methods of Making A Double Brew

Brewing Coffee

I suggested using a drip machine and a French Press to make a double brew earlier. But there are various other combinations you can choose from.

1. Drip Machine and Percolator

If you wish to ditch the French Press, you can use a percolator instead. Use your Drip Machine for the first round of coffee.

Once you have that ready, place the freshly brewed coffee into the percolator’s pitch. Next, place the coffee grounds into the filter and start brewing. The resulting double brew will be pretty intense, akin to an espresso.

2. Percolator and French Press


You can replace the drip machine with a percolator if you want a hands-on approach to coffee making.

You may spend more time preparing the brew since both methods are manually intensive. But the result will be a strong and flavorful coffee.

To begin with, pour room temperature water into the percolator’s pitch and place the coffee ground onto the filter. Allow it to boil and brew. While you’re waiting for the first batch, prepare a new batch of coffee grounds and pour it into the French Press. Pour the coffee from the percolator and allow it to steep for 4 minutes. Press the plunger after waiting for 4 minutes and pour into a cup to enjoy.

You can also try reversing the process and start with the French Press and end with the percolator.

3. Percolator and Percolator

Using Percolator

There’s no harm in using one method twice (unless it’s a drip machine). Making a double brew with a percolator twice will give you an acidic but smooth-tasting coffee.

For this method, follow the earlier instructions, and for the second round, replace the coffee grounds with a fresh batch. It’s better to wait for the percolator to cool down before putting in the fresh grounds.

Using the percolator twice is highly recommended when making iced coffee.

Finally, you can choose to use the French Press twice instead of a percolator. That works as well.


The double brewed coffee is a fantastic source of extra caffeine. If your schedule demands you to expend a lot of energy, you should try a double brewed coffee.

Trying different brewing methods is fun and will help you discover the various flavors of coffee. As long as you keep an eye on your caffeine intake, you’re good (and don’t risk your drip machine for the second batch).

Enjoy your coffee!
