    Following our recommendation of the OXO coffee storage system and our expressed interest in making a cold brew tutorial, the good folks at OXO® sent us their Cold Brew Coffee Maker. So we’re clear, this is not a paid endorsement. We really loved the way the OXO did the trick, and can’t wait to use it all summer long.

    Why Cold Brew Coffee?

    Matt Enjoying Cold Brew Coffee

    The regular coffee-making process uses hot water to extract flavor from the beans. However, done improperly, the process can end up extracting some things you don’t want in your coffee: bitter oils and fatty acids that contain ketons, ester and amids. These elements create the bitter and acidic tastes that cause most of us to add cream and sugar to coffee in order to counterbalance those flavor extremes.

    Cold brew, on the other hand, uses cold or room temperature water for extract. This takes a while (12 to 24 hours), but the result is significantly lower acidity. Between that and the temperature, it’s the perfect summer drink for coffee lovers. Click here to read more about the benefits of cold brew.

    Cold Brew Vs. Iced Coffee

    Cold Brew Vs Iced Coffee

    There’s a big difference between simply iced coffee and cold-brewed coffee. Cold brew is coffee brewed using cold water, whiled traditional iced coffee is strong, hot-brewed coffee quickly cooled and subsequently diluted by ice. Therefore, while icing coffee achieves the desired temperature, it still has the same acidity issues as poorly made hot brews.

    That’s what makes the cold brew system so much easier; essentially, cold brew coffee is harder to screw up. Here’s how to make it in what we think is the best way- with the OXO.

    How to Make Cold Brew Coffee

    What You Need

    1. Add Filter Screen and Filter Cap

    Filter Screen and Cap

    Add the filter screen to the filter cap, and screw the filter cap onto the bottom of the brewing container.

    Cold Brew Paper Filter

    Adding the paper filter that comes with the coffee maker

    Tip: To add an extra layer of filtration, the brewer comes with some optional unbleached round paper filters that can be used in addition to the screen. I used this when making my first and second batches, and I liked the result. Feel free to try it both ways and see what you prefer.

    2. Set Up the Brewer

    Place the brewing container on the stand. Make sure the brew release switch is in the off position!

    3. Grind and Add The Coffee Beans

    Grind and Add Coffee to Cold Brewer

    Grind 284 grams of whole beans to create 3.5 cups of ground coffee. Add to the brewing container and place the Rainmaker lid on top.

    4. Measure and Add The Water

    Measure and Add Water to Cold Brew Coffee Maker

    Pour 1200 ml (or 5 cups) of cold water in a circular motion through the Rainmaker and onto the grounds. Allow one minute for the coffee to bloom.

    5. Stir and Let it Brew

    Stir and Brew Cold Brew

    Remove the Rainmaker lid and gently stir the grounds. Then, place the Rainmaker back on, and let brew for 12 to 24 hours.

    6. Drain

    Drain Cold Brew

    After brewing is complete, slide the glass carafe under the stand and press the brew release switch to drain the coffee. The best things are worth waiting for, and this draining is no exception; it takes about 20 minutes. Talk about slow coffee!

    7. Dilute and Serve The Cold Brew Coffee

    Dilute and Serve Cold Brew

    Dilute the brew: mix 1/4 cup (about 60 ml) of cold brew to 1/2 cup (120 ml) of water. Use the provided stopper to seal the glass carafe and store the rest in the fridge- it’ll last a good two weeks.
