The most refreshing side of coffee

Cold Brew: the most refreshing beverage in the specialty world

Cold brew has gone from being a modern coffee shop trend to one of the favorite drinks for those looking for a different way to enjoy coffee. Its smooth flavour, low acidity, and refreshing profile have made it a staple in specialty coffee.

But what makes cold brew so special? Is it simply cold coffee, or is there really a difference in preparation and taste? In this article, we'll tell you everything you need to know about this drink that has conquered coffee shops and homes around the world.

What is cold brew?

Cold brew is a cold coffee extraction method. Unlike traditional coffee, which is prepared with hot water and then cooled, cold brew is slowly infused using cold or room temperature water for several hours.

This process completely changes the flavour profile of the drink. The result is a much sweeter, smoother, and more balanced coffee, with less bitterness and lower perceived acidity.

In specialty coffee, cold brew stands out because it allows you to appreciate sweet and fruity notes that often go unnoticed in more aggressive extraction methods.

How to prepare good cold brew?

Although there are different recipes, the base is always the same: time, cold water, and quality coffee.

Basic Ingredients

• Freshly ground specialty coffee

• Filtered water

• Extraction time between 12 and 24 hours

Recommended Ratio

A classic recipe usually uses a 1:10 ratio,

• 100 g of coffee

• 1 liter of water

The grind should be coarse, similar to that used for French press.

Step-by-step

1. Mix the ground coffee with the water.

2. Stir gently to ensure uniform extraction.

3. Let it steep for 12 to 18 hours in the refrigerator.

4. Filter using a paper, cloth, or metal filter.

5. Serve with ice or dilute to taste.

The result will be a concentrated drink that can be stored in the refrigerator for several days.

Why does cold brew taste different?

Temperature is key.

When coffee is extracted with hot water, oils, acids, and aromatic compounds are rapidly released. In contrast, cold extraction is much slower and more selective.

This produces:

• Lower perceived acidity

• More natural sweetness

• Less bitterness

• Fuller body

• Cleaner chocolate and fruity notes

That's why many people who find traditional coffee too intense particularly enjoy cold brew.

Cold brew vs iced coffee: are they the same?

No. Although both are served cold, they are completely different drinks.

Iced coffee

It is prepared with hot water and then cooled or served over ice.

Cold brew

It never comes into contact with hot water. All extraction occurs cold.

The difference in flavour is remarkable:

The importance of specialty coffee in cold brew

A good cold brew starts with good coffee.

When low-quality beans are used, the result is usually flat, bitter, or excessively earthy. In contrast, specialty coffees allow for much more complex and cleaner profiles.

Some particularly interesting origins for cold brew are:

• Ethiopia: floral and fruity notes

• Colombia: balance and sweetness

• Kenya: bright acidity and red fruits

• Brazil: chocolate and nuts

In addition, roasting also has a great influence:

• Light roasts: fruitier and more complex profiles

• Medium roasts: greater balance and sweetness

• Dark roasts: more intense and chocolatey flavours

How much caffeine does cold brew have?

There is a perception that cold brew has much more caffeine. In reality, it depends on how it is prepared.

Since it is usually made in a concentrated format, it can contain more caffeine per volume. However, many cold brews are diluted before serving.

In general, the final content will depend on:

• The coffee/water ratio

• The extraction time

• The type of bean

• The final dilution

What does usually happen is that, being smoother and less bitter, it is easier to drink.

Ways to enjoy cold brew

Cold brew is incredibly versatile.

Black and with ice

The purest way to appreciate its notes and nuances.

With milk

Ideal for those looking for a creamy and refreshing drink.

With tonic

A very popular combination in specialty coffee shops.

With plant-based drinks

Oat, almond, or coconut combine particularly well.

In mixology

Cold brew is also used in cocktails and mocktails thanks to its intensity and natural sweetness.

Tips for preparing a perfect cold brew at home

Use quality water

Water accounts for more than 95% of the drink.

Grind the coffee just before preparing

This helps preserve the aromas and flavours.

Don't over-extract

More time doesn't always mean better flavour. Excessive extraction can add bitter notes.

Filter well

Clean filtering improves texture and prevents sediment.

Experiment

Each coffee responds differently to cold brew. Changing the origin, roast, or recipe can completely transform the result.

The rise of cold brew in specialty coffee shops

The growth of cold brew reflects how coffee culture has evolved.

Today, consumers are looking for:

• More refreshing drinks

• More complex flavour profiles

• Artisanal methods

• Different experiences

Cold brew brings together all these elements.

In addition, it fits perfectly with the focus of specialty coffee: respect for the product, care in extraction, and a constant search for quality.

In summary...

Cold brew is not simply cold coffee. It is a completely different way to extract and enjoy coffee.

Its smoothness, sweetness, and complexity make it a perfect option for both those who already love specialty coffee and those who want to get started in this world.

And as with any preparation method, the difference always lies in bean quality and the attention to every detail.

If you haven't tried cold brew made with specialty coffee yet, this may be the perfect time to discover a new way to enjoy your coffee.
