Coffee is one of the most popular beverages in the world, with millions of people enjoying it every day. But coffee is not just a hot drink that wakes you up in the morning. It is also a versatile and delicious beverage that can be enjoyed cold, especially in the warmer months.
Cold coffee has been around for a long time, but in recent years, it has gained a new level of popularity and innovation. Thanks to the emergence of cold brew and nitro coffee, cold coffee lovers have more options than ever to satisfy their cravings and explore new flavors.
In this article, we will explore the cold coffee revolution, from its origins to its future. We will compare and contrast cold brew and nitro coffee, explain how they are made, and discuss their benefits and drawbacks.
We will also look at some of the flavor innovations and customization options that cold coffee offers, as well as the trend of serving nitro coffee on tap in coffee shops.
The Rise of Cold Coffee Beverages
Cold coffee is not a new phenomenon. In fact, it has been around for centuries, with different cultures and regions developing their own versions of iced or chilled coffee drinks.
For example, the Greeks have frappé, a frothy iced coffee made with instant coffee, sugar, and water; the Vietnamese have cà phê sữa đá, a strong iced coffee with sweetened condensed milk; and the Japanese have mizudashi, a cold brew method that involves steeping coarsely ground coffee in cold water for several hours.
However, cold coffee has become more mainstream and popular in recent years, especially in the United States. According to the National Coffee Association, the percentage of Americans who drink iced or cold brew coffee increased from 19% in 2015 to 26% in 2020. This growth is driven by several factors, such as:
The increasing demand for convenience and portability. Cold coffee can be easily prepared at home or bought ready-to-drink from grocery stores or cafes. It can also be consumed on the go, without the need for heating or reheating.
The rising preference for health and wellness. Cold coffee tends to be less acidic and bitter than hot coffee, which makes it easier on the stomach and more appealing to those who are sensitive to caffeine or acidity. Cold coffee also offers more hydration and refreshment than hot coffee, which is important for staying hydrated in hot weather.
The expanding variety and innovation of cold coffee products. Cold coffee is no longer limited to traditional iced coffee, which is simply hot brewed coffee poured over ice. Instead, consumers can choose from different types of cold coffee beverages, such as cold brew, nitro cold brew, flavored cold brew, sparkling cold brew, and more.
Cold Brew vs. Iced Coffee: What’s the Difference?
One of the most common questions that cold coffee drinkers ask is: what is the difference between cold brew and iced coffee? While both are cold coffee beverages, they are not the same thing. The main difference lies in how they are brewed.
Iced coffee is made by brewing hot coffee using any method (such as drip, pour-over, French press, etc.) and then cooling it down by pouring it over ice or refrigerating it.
This process is quick and easy, but it also has some drawbacks. For one thing, pouring hot coffee over ice dilutes it and makes it watery. For another thing, brewing hot coffee extracts more oils and acids from the coffee beans, which can result in a bitter and sour taste.
Cold brew, on the other hand, is made by steeping coarsely ground coffee in cold or room temperature water for 12 to 24 hours.
This process is slow and requires more planning ahead, but it also has some advantages. For one thing, steeping cold water extracts less oils and acids from the coffee beans, which results in a smoother and sweeter taste. For another thing, steeping cold water produces a concentrated brew that can be diluted with water or milk without losing its flavor.
The Art of Cold Brewing
Making cold brew at home is not difficult, but it does require some patience and equipment. Here are the basic steps to follow:
Choose your coffee beans.
You can use any type of beans you like, but medium or dark roasts tend to work better for cold brew because they have more body and flavor. You can also experiment with different origins or blends to find your favorite.
Grind your beans coarsely.
You want to use a coarse grind size that resembles sea salt or breadcrumbs. This will prevent over-extraction and bitterness. You can use a burr grinder or a blade grinder for this purpose.
Measure your ratio of coffee to water.
The ideal ratio depends on your personal preference, but a common one is 1:4, meaning one part of coffee to four parts of water. For example, if you want to make 1 liter of cold brew, you will need 250 grams of coffee and 1 liter of water.
Combine your coffee and water in a container.
You can use any large container that has a lid, such as a mason jar, a pitcher, or a French press. Make sure to stir well to ensure that all the coffee grounds are wet and submerged.
Steep your coffee in the fridge or at room temperature.
The optimal steeping time depends on your desired strength and flavor, but a general range is 12 to 24 hours. The longer you steep, the stronger and more flavorful your cold brew will be.
Strain your cold brew.
You can use a fine-mesh strainer, a cheesecloth, a paper filter, or the plunger of a French press to separate the coffee grounds from the liquid. You may need to strain more than once to get rid of any sediment or sludge.
Enjoy your cold brew.
You can drink your cold brew as it is, or you can dilute it with water or milk to your liking. You can also add ice, sugar, creamer, or flavorings to customize your cold brew. You can store your cold brew in the fridge for up to two weeks.
Nitro Coffee: Infusing Nitrogen for a Creamy Experience
If you are looking for something different and exciting in your cold coffee, you may want to try nitro coffee. Nitro coffee is cold brew coffee that has been infused with nitrogen gas under high pressure. This process creates millions of tiny bubbles that give nitro coffee its distinctive characteristics.
Nitro coffee has a creamy, thick, and velvety texture that resembles a Guinness beer or a latte. It also has a sweeter and smoother taste that reduces the need for added sugar or creamer. It also has a cascading effect that creates a beautiful visual presentation.
Nitro coffee is usually served on tap in coffee shops, where it is stored in kegs and dispensed through faucets. However, you can also make nitro coffee at home using special devices or kits that allow you to infuse nitrogen into your cold brew. Here are some examples of how you can make nitro coffee at home:
Use a whipped cream dispenser.
This is a device that uses nitrous oxide (N2O) cartridges to whip cream or other liquids. You can use it to make nitro coffee by following these steps:
- Dilute ½ cup of cold brew with ½ cup of water.
- Pour your coffee into the whipper and seal it tightly.
- Charge with one shot of nitrous oxide and give the dispenser a good shake for about 30 seconds.
- Discharge the canister and pour your nitro cold brew over ice.
Use a nitro brewer.
This is a device that uses nitrogen (N2) cartridges to infuse nitrogen into liquids. You can use it to make nitro coffee by following these steps:
- Fill the brewer with cold brew coffee and screw on the lid.
- Charge with one shot of nitrogen and give the brewer a good shake for about 30 seconds.
- Dispense your nitro cold brew into a glass using the tap handle.
Use a nitro keg system.
This is a device that uses a nitrogen tank and regulator to infuse nitrogen into liquids. You can use it to make nitro coffee by following these steps:
- Fill the keg with cold brew coffee and seal it tightly.
- Connect the keg to the nitrogen tank and regulator using hoses and fittings.
- Adjust the pressure to about 30 psi and let the keg sit for about an hour.
- Dispense your nitro cold brew into a glass using the tap handle.
