It’s my favorite season again; cold brew season! Iced coffee in glass cups behind tall windows, as your whole being gets warmed by a magnified sun. It used to be that I would enjoy nothing more than biking to a favorite local coffee spot, ordering a glass of cold brew, and being swallowed by a nook with one of their magazines to peruse. I wouldn’t say “gone were the days”, but I did shift some habits within the last year, and paying $4 a cold brew a few times a week stopped being something I looked forward to. Luckily, I’ve got Mike to guide my hand in creating my own at home. The truth of the matter is, it’s a very simple process that hardly takes time or work at all. It can be steeped overnight as you sleep and dream of coffee things, and then pre-prepared and stored in the fridge in batches of 10-20 cups. According to Mike, it should only last a week in the fridge, but that’s not much of a problem at our house. Plus, I consider less than $1/cup a frugal win. The best part? Accessibility of iced-coffee drinks, at all times.
Tools You Need:
There are a few gadgets that you will need in order to make cold-brew at home. These are some of our gadgets that we are not impartial to.
- Scale – I own this one, because it weighs heavy-enough things for bread-making as well. I also like this because I can toggle between grams and ounces. Mike has this one
that he uses for coffee exclusively, which is what we mostly use when measuring coffee bean and water weight. It is especially useful since it has that timer, essential to latte pulls and drip-coffee!
- Grinder – The grinder plays a huge role in the quality of your brew (or espresso, or latte, or what-have-you). We used to just live with the results of a sub-par grinder, until last Christmas, when our gift to each other was a high quality grinder
that has been spewing out delicious pours ever since.
- French Press – Mike has owned a French press way before a Chemex or an espresso machine, and this may have been his first introduction to coffee. To be honest, prior to the habit shift of making cold-brews at home, all the French press has done the last couple of years is look pretty on a shelf. I am so glad that I can finally make use of this beauty once again.
- Chemex – You can use any drip-coffee vessel, but we love our Chemex. We like the style with the glass handle, but there are ones with a wooden middle, if aesthetics are more of a concern. We use it for extracting hot coffee brews as well, but the summer time is going to change that.
- Gooseneck Kettle – Precision is key when making a pour-over cup of coffee. We own the Fellow’s stovetop Stagg Kettle and love its slender gooseneck. It allows us to pour water slowly and with control. Plus there is a thermometer lid which ensures the correct water temperature each time (a must!). I would recommend this brand to anyone who wants to make a good pour-over. If you would like, they have an electric version too!
- Filter – We used to buy disposable paper filters for our Chemex. Over the holidays, Mike’s sister gifted us a pair of reusable hemp filter, and we have never thrown a filter out since then. Surprisingly, it is such an easy clean up process. You simply wash it like you would a towel and hang to dry.
A similar one, here. - Fresh, whole coffee beans (To make about 10 cups, use 125 grams of coffee beans to 500 mL of water. For about 20 cups, use 250 grams of coffee beans to 1 L of water.
- Water
- Serving vessel or container – To store my cold-brew concentrate, I simply use mason jars (surprise, surprise). We DO have refillable howlers and growlers, wherein Mike likes to store already-diluted cold-brew.
The Process:
- Weigh the appropriate amount of coffee beans and grind them at a medium-coarse setting. If you are using the same grinder as us, we usually have the setting around 9E.
- Set the French press on top of the scale and add the ground coffee. Tare the scale.
- Fill the French press with the proper amount of cold water. Use a spoon to stir the coffee, making sure all the grounds are wet.
- Put the lid of the French press into place and press the filter down just enough to submerge the coffee below the water. Let the coffee steep at room temperature for about 12 hours. Usually we prepare this part in the evening around dinner time. We then leave it on the counter overnight and it is ready to be prepared the next morning. You can also make this in the morning before you head off to work, and then in the evening, you can continue the steps and let it cool in the fridge overnight. Really, this is very flexible for multiple schedules.
- After 12 hours, slowly plunge the filter to the bottom of the French press.
- Place the filter in the Chemex. Pour the cold brew concentrate from the French press through the filter, letting the coffee drip through.
- Before drinking, you will need to dilute the cold-brew concentrate using the following ratio: 1 part concentrate to 3 parts water, making sure to use a scale for accuracy. For the non-picky, you can always eyeball it, or decide based on your taste preference. For the especially particular, measuring is the way to go. Pour over ice. This can be stored in the fridge for up to 1 week, before it starts to degrade. For me personally, I just store the concentrate and ration it out whenever I am ready to drink. Mikey likes everything pre-prepared for even more accessibility throughout the week. To each their own!
