In an earlier article titled Cold Brew Coffee is Not Rocket Science, I outlined just how easy it was to make cold brew coffee at home. No matter how you tackle the task of making cold brew, it all breaks down to some basic steps:
- Grind coffee to a medium coarse or regular coarse setting.
- Place coffee inside some filter.
- Put that filter in cold water.
- Wait 12-24 hours.
- Remove the filter and serve.
There is one remaining step. That is cleaning everything up and so your cold brewer is ready to go for the next time you brew coffee. Some of the more basic methods require a little more time spent on cleanup. In this tutorial, I’ll show you how to make cold brew coffee using the Cold Brew Coffee Maker from Home and Above. Not only is it easy to use, but it is super easy to clean up.
Why I Like the Cold Brew Coffee Maker
The first step in using a new coffee brewer is figuring out the math. How much coffee do I use? Is that in grams? Where is my scale? Now, how much water do I need? With the Cold Brew Coffee Maker it is very simple. It is as if they anticipated these questions when they designed the brewer.
Along the side of the brewer, they have markings for 8 oz, 16 oz, 24 oz and 32 oz. Pretty cool. Now I don’t need to use a measuring cup to add water. For this brewer, I only advise only using the 32 oz mark. Below 16 oz and the coffee filter does not make contact with the water. At 24 oz, not all the coffee will be under the water line. But at 32 oz, the water line reaches exactly to the level in the filter where the ground coffee reaches.
Also note that once you remove the filter, you won’t get 32 ounces of coffee. It will be closer to 24 ounces.
The other thing I like about this brewer is the design. Not only does it functionally perform its task as a cold brewer, but it looks nice on the counter. And when the coffee is finished brewing, it has a nice handle that makes pouring easy.
Let us make some cold brew coffee.
#1 Grind 1 Cup of Coffee
A common ratio in cold brew coffee is 4 to 1. This means 4 parts water for 1 part coffee. 32 ounces is 1 quart. 4 cups in a quart. Divide by 4 and we get 1 cup of coffee. For those that prefer grams, use 85 grams of coffee. The coffee should be ground medium coarse to coarse. See our Coffee Grind Chart for more guidance, but don’t be concerned with being exact. Cold brew is very forgiving.
#2 Place Filter in Brewer and Add Ground Coffee to Filter
Place the metal filter inside the Cold Brew Coffee Maker. Then add the 1 cup of ground coffee into the metal filter. Make sure to brush off any loose grounds on the top lip. Or alternatively, you can use a funnel. If you have an AeroPress, you can use that funnel. It fits perfectly.
If you have a funnel, use it. Otherwise, brush the loose grounds down into the filter.
#3 Add Cold Water
Slowly pour cold water over the coffee grounds. Continue pouring water until the water reaches the 32-ounce line.
#4 Add Lid and Wait 12-24 Hours
Place the lid on top of the brewer. At this point, all we need to do is let the brewing happen.
Place the brewer out of the way somewhere for 12-24 hours. I brew on the counter at room temperature. There is an exposed opening at the top where you will pour later. If you are concerned about dust or fruit flies in the coffee, place a plastic bag or plastic wrap over the top of the brewer during the 12-24 hours while it is brewing.
#5 Remove Filter and Serve
Even though the lid should be firmly attached to the metal filter, I advise slowly removing the filter. Set the filter in the sink for now, because a small amount of coffee will continue to drain out.
Depending on your own personal taste and how long you brewed the coffee, it might be too strong. If so, just add water to taste. At this point, you can serve over ice or place in the refrigerator to chill. Or you can heat it up in a microwave and drink your coffee hot. Even hot, your cold brew will retain a clean low acidity taste.
Remove the lid and knock the grounds into a compost bin. At this point just give the filter a quick rinse or you can put it in the dishwasher. I wash mine by hand. Even though it is dishwasher safe, I don’t know how many cycles in the dishwasher could damage the rubber lip where the lid secures into the filter.
If the coffee tastes too strong, you can add water and in the future use either a shorter brewing time, less coffee or a more coarse coffee ground. If the coffee tastes too weak, you can use a longer brew time or use a finer ground coffee. Adding more coffee likely wouldn’t help with this brewer since the additional coffee would be above the water line.
I’m a big fan of the design of the Cold Brew Coffee Maker from Home and Above. The only issue is the exposed lip during the brewing, but this is easily solved by covering with an upside-down plastic bag. Don’t waste your money in the coffee shops buying expensive cold brew coffee. It is too easy to make it yourself. Cold Brew coffee is also an ideal coffee for people pressed for time in the morning. Time the brew so it is finished before you leave your house. Pour and go.
