What is Cold Brew Coffee?
Cold brew coffee is a drink that involves brewing ground coffee in cold water for a long period of time. This creates a strong and smooth cold coffee drink that be enjoyed with added syrups or creams. This is different from iced coffee that involves pouring hot coffee over ice.
Cold Brew Coffee is More Than Just Cold Coffee
Most people assume that cold brew coffee can be made by simply brewing a regular coffee and throwing some ice and cold water in there. That would actually be an iced coffee. It actually involves more technique and timing to produce the perfect outcome.
The way to brew regular coffee is to use hot water to extract the coffee goodness from the roasted beans. With cold brew coffee, rather than using hot water, it uses cold or room temperature water instead. The way to extract the coffee goodness in this method is through steeping the grounded coffee beans for at least 12 hours, the long process allows enough time for the chemical reaction and the water to absorb the flavors from the coffee grounds.
Once you have your cold brew coffee concentrate, you can upgrade it by adding more ice or blending with either milk or creamer. There is also the option to add syrups, sugar, and other unique flavorings to your liking. That’s the benefit of making cold brew coffee at home.

There are 4 main reasons why cold brew coffee is special. This includes reduced acidity, being able to be heated up, having a long shelf life, and being able to be enjoyed on hot summer days.
The first might come as a shock to some, but you can serve cold brew as a hot beverage, not just cold. We prefer to just make a hot coffee but understandably, cold brew coffee will have reduced acidity, which might be more preferable to some people. If you do wish to heat it up, there shouldn’t be any effect on the taste or the coffee itself.
The second that makes cold brew special, as mentioned above, is that it has lower acidity levels compared to regular coffee. This is due to a number of reasons including heat, chemical reactions, and the amount of water used. It can be a great option for those who are advised to steer clear of coffee due to the acidity.
The third is that you can store cold brew for up to two weeks without worrying about it being stale. The general idea is that it can last between 7 and 14 days. This would depend on the temperature, the coffee, and the amount brewed.
The final reason as to what makes cold brew coffee special is that it can be enjoyed on hot days. There are many people that avoid their favorite coffee drinks in the summer because it can cause them to overheat. With cold brew, you have a refreshing cold drink that can be served with ice, and it still gives you a caffeine kick.
How to Make Cold Brew Coffee?
A cold brew coffee is very simple to make and requires few ingredients. It’s not the best choice of drink if you are looking to drink it instantly as you will need to wait around 12 hours for the coffee to brew correctly. All you need is medium-coarse coffee beans, room temperature or cold water, and patience to wait for at least 12 hours. Make sure that you use an airtight container when you store it in the fridge to maintain its freshness.
Follow these steps to make the perfect cold brew:
- Find the perfect coffee for your drink. We recommend this single origin coffee or this coffee subscription.
- Choose your devices. Some prefer a French Press for the filter, and some will use a jug. If you use a large container, you will need to filter the coffee, which can be difficult depending on the size.
- Grind your coffee beans on a coarse setting or use pre-ground coffee.
- Measure out your water based on the coffee to water ratio. Some recommend a 1:4 and some a 1:8, experiment with both and see what works best for you.
- Add the coffee grounds to your container.
- Add the water over the coffee.
- Store in the refrigerator and allow steeping for 8-24 hours. This time will vary based on the amount you make and how strong you like it. If you like it strong, leave it for longer. You can always taste it throughout the day.
- Remember to filter out the coffee once it’s ready, and your drink will be ready. Store it for 7-14 days in the refrigerator and drink when needed.
The key thing to remember here is that following any guide or recipe online might not work for you. You should use it as a rough guide and experiment with what works for you. For example, if you like weak coffee, try only leaving the cold brew for 7 hours. If you like it sweet, add cream to it after with syrup.
Now, if you’re still not convinced about making this drink, imagine getting fresh coffee every day without having to brew it every single time. All you need is one day to make a coffee batch, and you’re all set for the entire week. But if you don’t want to make it, try buying it online or in a grocery store instead.
