“Give me a sun, I care not how hot, and sherbat, I care not how cool, and my Heaven is as easily made as your Persian’s.” Lord Byron wrote these words in 1813 praising the sherbat, a popular drink in the Middle East since the early Middle Ages.

In 1626, the philosopher Francis Bacon had already tasted it. Sherbat, which comes from the Arabic word for “drink” is considered the first soft drink or non-alcoholic soda.

It is, essentially, a drink made with syrups and spices. It also became popular in the West and was widely consumed until the advent of carbonated beverages.

That’s where the word “sorbet” comes from.What we propose is that you continue this tradition to create your own sherbat: a cold brew coffee that would make Lord Byron dedicate a couple of verses to it.

What is Cold Brew Coffee and how to make it

A cold brew coffee it’s a cold coffee extraction

Cold brew coffee is a cold coffee extraction. But it is not a hot coffee infusion that has been allowed to cool down, it is an infusion in which the extraction has been done with cold water.

And therein lies the difference. The cold extraction of coffee is carried out by immersing the coffee in water for a long period, which can last from 12 to 24 hours.

The cold extraction releases less acidic and bitter compounds from the coffee, thus producing a drink with sweeter notes. A study in the journal Nature shows that our perception of acidity and bitterness increases with hot or cold flavours.

How a Cold Extraction Affects Flavour

Acidity can be a good thing in coffee, it is one of the 5 basic tastes and it can help to highlight and create tasting notes.

Even a subtle hint of bitterness can be of benefit since, according to the Coffee Research Institute, it can offset too much acidity.

But if we do a hot coffee extraction and we let it cool down or we cool it down with ice, we run the risk that it becomes too acidic or bitter.

Elaborating a cold brew coffee, something that we can easily do at home, can prevent too acidic or bitter-tasting notes from emerging.

Cold brew coffee will highlight different tasting notes than a hot extraction.

The history of Cold Brew Coffee

What is Cold Brew Coffee and how to make it

The Kyoto Coffee is cold and slow dripping coffee extraction

Sometimes when something becomes fashionable, as has happened with cold brew coffee in recent years, we run the risk of believing that it is something new. But something being trendy doesn’t necessarily mean it’s new, and the way you make cold brew coffee isn’t either. In Japan, cold brew coffee has been served since, at least, 1600.

It is known as “Kyoto Coffee” and it is said to have been introduced by Dutch merchants from Indonesia, who used it as a way to prepare coffee when they were travelling by sea.

The Japanese, with their zest to make an art of everything, soon began to create slow drip devices so that the extraction of coffee was not just delicious, but also a visual pleasure.

Cold Brew Coffee Comes to The West

What is Cold Brew Coffee and how to make it

The Toddy is a easy method to make a cold brew

It is around 1800 when different coffee concentrates and syrups start to be produced and sold in the West. Due to their high concentration of caffeine (and sugar!), they became a common drink amongst soldiers; it is said that it was the French legionnaires in Algeria who started drinking it.

The first to sell cold brew coffee was the Japanese company Ueshima Coffee Co. followed by the Italian giant Illy. In the United States, cold brew coffee was popularized by a chemist, Todd Simpson, who created an easy method to prepare it (the “Toddy cold-brew coffee system”) during a trip to a plantation in Guatemala.

Today cold brew coffee can be found in many different forms and formats (and qualities!), both in the supermarket (although that is not what we would define as cold brew) and in your specialty coffee shop. The important thing is to be aware that fashion does not mean novelty, as it doesn’t mean quality either. For quality, we have to pay attention to how to make a cold brew correctly.

What Goes Into a Cold Brew Coffee?

The basic ingredients of a cold brew are coffee and water. As simple as that, and as delicious as it can be. The procedure is very simple: immerse the coffee completely in water for a long period and then filter it carefully before serving.

As with all our coffee brews, depending on the recipe that we follow, we will achieve different results. The final quality of our cold brew will depend, to a large extent, on the quality of the ingredients that we use in the recipe.

As always, we recommend using freshly ground specialty coffee and water with a dry residue between 125/175 mg per litre.

Cold Brew Coffee Recipe

What is Cold Brew Coffee and how to make it

Steps to make a cold brew coffee at home

This is the cold brew coffee recipe that we suggest to make 600 ml of cold brew. The ratio, in case you want to increase or decrease this amount, is 1 gr of coffee to 15 gr/ml of water. You will need:

  • Coffee 40 gr
  • Water 600 gr/ml
  • A mesh or a silk cloth
  • A glass container

The Process to Elaborate a Cold Brew Coffee:

  1. Grind the coffee to a medium size
  2. Pour the ground coffee directly into the mesh (the finer the mesh the cleaner and less sediment we will have in the final drink)
  3. Introduce the mesh in a glass container
  4. Pour the water into the container through the mesh with the coffee
  5. Stir gently
  6. Cover the container
  7. Let it rest for 15 hours in the refrigerator (pay attention to strong odours!)
  8. After this time, remove the mesh with the coffee and the cold brew should be ready.

How to Make a Cold Brew in a French Press?

What is Cold Brew Coffee and how to make it

You can also make a cold brew coffee with a French Press

Other than the above recipe, you can also make a cold brew using your French Press or plunger coffee maker. The ingredients, the method and the water/coffee ratio are the same. Simply, instead of using a mesh, use the plunger’s filter to separate the solid waste from the coffee.

Following the same quantities that we have described above, the procedure would be:

  1. Pour the ground coffee into the coffee maker
  2. Fill it with the right amount of water
  3. Stir, cover and leave to rest in the refrigerator
  4. Once the appropriate time has passed, push/filter the coffee residues to the bottom of the coffee maker and serve carefully.

Does Cold Brew Coffee Have More Caffeine?

What is Cold Brew Coffee and how to make it

A cold brew coffee has more caffeine than a hot brew

There are more ways to prepare cold brew coffee, other than the ones we have suggested. The basic idea is that for a cold extraction a long infusion time is required and we need to take into account the coffee/water ratio.

We always have the possibility of buying the cold brew already made. Many specialty coffee shops sell it already packaged. But, as with any coffee brew, the time passed since we prepared it will influence its flavour due to the natural oxidation process it undergoes.

Given the ease of preparing a cold brew, we recommend that you try making it at home, which will also allow you to experiment with different coffees and recipes until you find the one you like the most.

Keep in mind that the longer the contact time between coffee and water, the greater the dissolution of solid compounds and, therefore, the higher the concentration of caffeine.

But this summer we hope you need all that caffeine and more.

So… enjoy it responsibly!
