Deep, rich, cool and creamy iced coffee! In a hot summer, there is nothing like it. It’s so easy to try it yourself at home. I have been making iced coffee for years now. Through lots of trials and error and after trying it in various ways, I settled upon the cold brew method. It’s a magical taste without the shiver-inducing, bitter acidity. You can get this pure mild-tasting at your home. In the following segments of this article, I will show you ‘How to make cold brew coffee concentrate.’

What to Know About Cold Brew Coffee Concentrate?

Recently the cold brew coffee has the market buzzing. And there is a lot of reasons behind that. For nearly half of the consumers said that taste is the primary reason for drinking cold brew coffee. It is even above the need of coffee cravings. Recent reports suggest that consumers can really taste the difference of cold brew coffee concentrate.

The point to telling you this entire thing is that, the taste of the cold brew is the main thing to consider. Coffee bean type, grind size, roasting method, steep time and temperature are the critical criteria for having the best cold brew coffee concentrate.

Choosing the Coffee Bean

African coffee beans have more exotic notes like blueberry or citrus, while the Brazilian beans are more nutty and earthy with cocoa tones. With this example, you can start making some generalizations about coffee beans. But, it is very hard to say whether a bean will have certain specific properties. There are many things that can impact the final flavor profile of coffee bean. Such as:

Choosing the Coffee Bean

  • Differences in soil characteristics
  • Growing elevation
  • Humidity and temperature of the region
  • Levels of moisture
  • Amino acid quality and quantity and the number of chlorogenic acids in the green bean

The adopted processing steps of the coffee bean can also impact the flavor of the coffee. The processing steps such as natural, semi-washed or washed from the cherry before the drying step can modulate the chemical compounds of the coffee bean. You will be amazed to know that neighboring farms producing the same ‘varietal’ can have variation.

You can use any bean for a cold brew. So, when you are selecting beans, consider the flavors you want and be open to brewing a blend to get the best product.

Determining the Roast Level

The roast level can also have impacts on the taste profile of cold brew coffee. Chemical reactions and changes to the beans’ structure can happen due to the process of applying heat to raw coffee beans.

The darker roast will make the beans caramelize, enhancing the sweet, brown, roasted notes that are staples in coffee profiles. You need to roast the beans for longer times and to the hotter temperatures. You can characterize the dark roast by the smoky aroma.

The bean will highlight brighter acidity and more delicate nuances if you roast them for shorter times and to lower temperatures. If the roast is too light, the beans will have underdeveloped flavor profiles. This will highlight grassy notes and too-high acidity.

Keeping the Right Water Volume and Grind Size

For a balanced extraction during the cold brew process, the grind size is very important. The coffee extraction will have a profound impact if the grounds are larger in size. Because there will not be enough surface area in contact with the water. This will give you a light and weaker cup of cold brew. For smaller grounds, the coffee may pull too much bitterness in a dark roast. In addition, the coffee will be too acidic.

To get a good cold brew, you should use a coarse grind. You have to use more grounds than usual to increase your coffee: water ratio.

Understanding Brewing Conditions

As the name suggests, the cold brew is typically cooler than the traditional hot brew. For this reason, you can assume that there is no standard range of extraction temperature for a cold brew. For the traditional hot brew, the temperature is, however, 185F to 205F.

You need to steep grounds in cool or room temperature for 12 to 24 hours to get the best tasting cold brew coffee. The longer the brew times are, the smoother and sweeter flavor profiles are.

The Easiest and Safest Way to Brew Coffee

Cold brew coffee is definitely a hot commodity now. They seem to be popping up everywhere. From the rows of bottled coffee concentrate to the numerous cold brew coffee concentrate kits, it has become a trend.

French Press is the easiest with all the options you have to brew coffee. Other methods like a coffee filter, cheese cloth can be messier. French press separates the coffee bean grounds from the liquids conveniently.

The Easiest and Safest Way to Brew CoffeeIn the following section, I will show you how to make cold brew coffee concentrate in the easiest and safest way.

Preparation of the Coffee Beans

You can divide this process into three sections. They are like picking the beans, grinding the beans and adding water to them.

Picking the Beans

Picking the right beans is always important to make a perfect cold brew coffee concentrate. You need to get your hand to dark roast coffee beans.

Grinding the Beans

After getting your favorite dark roast coffee beans, start grinding them roughly. You may also use the pre-ground beans.

Adding Water

Take the French Press container and place the grounded coffee beans. Pour filtered water and stir vigorously to combine.

Steeping Coffee Beans

After adding and combining the water, you have to cover the container and rest the beans to steep. Keep them in room temperature for 8 to 12 hours.

In the following morning, to filter out the coffee beans from the liquid, you need to press down on the French Press plunger slowly.

Why Are Room Temperatures Important?

In the previous part, I asked to steep the coffee beans at room temperature. That isn’t literally ‘cold brewed,’ is it? You may brew the coffee beans in the refrigerator, but it will take a longer time. However, the result will be the same.

Why Are Room Temperatures ImportantSince you don’t brew the coffee beans with hot water, you can easily encompass it as ‘cold brew.’ On the whole, the easiest and safest way to brew cold coffee concentrate is to steep it in room temperature.

Straining Beans

Just place a filter over a jar or bottle. Then run the concentrate through the filter to separate the grounds. Just, as simple as that.
