Good news: Cold brew coffee concentrate is really easy to make at home.
Here’s how to do it:
1. In a jar, a pitcher or a big bowl mix 1 cup coarsely ground coffee and 4 cups cold water. Stir to ensure all the grounds are wet.
2. Cover and let rest at room temperature overnight or 12 hours.
3. Strain twice through a fine mesh strainer lined with cheesecloth or a coffee filter. Pour slowly and allow to drain completely.
Refrigerate for up to two weeks.
This is my basic recipe that makes 4 cups coffee concentrate. That’s enough for 8 cups of coffee/iced coffee. Of course, you can double or triple the original quantity if you’d like to make a big batch. Any pitcher, bowl or container will work here but if you prefer, you can use cold brew coffee makers like Toddy ($32) or Hario cold brew pot($19).
How to use coffee concentrate?
Fill a glass with ice. Pour in 1/2 cup (4 oz) coffee concentrate, add 1/2 cup cold milk (or even better, half and half) and sweeten to taste. Stir to combine. Taste and adjust half and half/sugar as needed. For Vietnamese iced coffee, fill a glass with ice, pour in 1/2 cup coffee concentrate, 2 rich tablespoons sweetened condensed milk, 2 oz milk or half and half and stir.
To serve hot, combine coffee concentrate and hot water in 1:1 ratio.
You must give the cold brew a try. The coffee is less bitter, has almost no acidity and it’s so convenient. Not to mention the savings. This cold brew concentrate is perfect when serving coffee (hot or iced) to a crowd. And, it makes fantastic gifts too.
