Making A Purrfect Cold Brew
With coffee being all the rage these days, people are trying everything they can to make coffee just like their favorite café. There are so many ways to try coffee, from espresso and cappuccino to French press and pour over. We’ve discussed the art of the pour over, along with several of the other ways to brew your coffee here on Cool Cats. But there’s one trend we haven’t covered.
Who doesn’t love a good ice-cold coffee on a warm day?
Of course, who says it has to be a warm day to enjoy an ice-cold brew?
With cold brewing becoming more mainstream these days, people are becoming more and more curious as to what exactly cold brewing is and how to have it done without having to go to the store. But what makes cold brew so special?
Why cold brew?
Since this is primarily a concentrate more than actual coffee, your brew is going to have a lower acidity. Drinking too much coffee can cause intense heartburn for those with acid reflux and that’s never a fun way to enjoy a cup of coffee. While regular hot coffee can cause your stomach to negatively react, a good cold brew will ease that side-effect.
While in a traditional brew, you’re exposing the grounds to high temperatures, the cold brew is the exact opposite. A good cold brew is going to come out sweeter and smoother. Some drinkers have reported that they really aren’t relying too heavily on their creamers, sweeteners, or sugars because they’re tasting the naturally sweet taste of their coffee. Most drinkers will be drinking a cold brew black or even adding a little milk.
The versatility of a cold brew makes it perfect for either a hot or cold drink. Since you’ve already chilled the concentrate, you can easily pour it over ice and head out the door. But if you’re in the mood for a hot cup of coffee, you can boil the water and add it to the cold brew concentrate. A regular brew of coffee doesn’t last all that long. With the concentrate, you can refrigerate for as long as 2 weeks before having to dispose of it. You can easily pour yourself a cup at any time and with any preference.
The cold brewing coffee process starts with making a coffee concentrate instead of straight coffee like with the traditional drip coffee machines.
With cold brewing, it’s more of a matter of time, than the matter of heat when it comes to the actual brew. The technique is called “immersion” and happens when the coffee grounds are left in the cold water to soak, also called “brewing” over an extended amount of time. This time can vary from 18 to about 24 hours, depending on the cold brew machine you get. This brew is then poured through a filter and creates a concentrate. Normally, the “cold brew concentrate” is poured over ice to create that cold brew.
You’re going to want to have more of a coarsely ground bean instead of the super fine textures you would in other brews. You’re looking for something roughly the size of breadcrumbs. The finer the grind, the “grimier” the texture is going to be.
Once you have your grind perfect, you’ll place the grounds into your cold brew maker and add the cold water. Stir your mixture until it is well combined, then leave at either room temperature or in the fridge for roughly 18-24 hours. Do note: if you store it in colder temperatures, you’ll need to steep longer.
Once the steeping is finished, you’ll drain the mixture out about 2 or 3 times until all of the residue is out of the bottom. Then you can serve however you like!
The strength of your coffee is going to depend on how many beans you’ll add to the brew. The more beans to water will give you more caffeine. Just like any coffee related mixture, this is all a matter of trial and error, but there are tons of great recipes out there to try. The coffee-to-water ratio being used is much higher than your traditional roasts. You’ll be using more beans per ounce of coffee than you would in the traditional roasts. The cold brew concentrate would have something close to over 500mg of caffeine per 8oz of liquid. The hot brew that most coffee drinkers make would have roughly 100mg of caffeine per 8oz of liquid.
1) Grind coffee into a coarse grind
2) Immerse ground beans into water for 16-24 hours - perferrably in your new Cold Brew Maker
3) Remove coffee grounds from water and discard
4) Enjoy with ice & your favorite cream! We also recommend adding extra water
