How To Brew Mason Jar Coffee? Making Cold Brewed Coffee

Brewing cold brew coffee in a Mason jar is incredibly simple and requires minimal equipment. Here’s a step-by-step guide to making a delicious cold brew at home.

Ingredients and Equipment:

• 57 grams of coarsely ground coffee beans
• 34-oz wide mouth Mason jar
• 2 cups of room-temperature or filtered water
• Mesh strainer or cheesecloth
• Additional paper coffee filter (optional)

Instructions:

1. Weigh The Coffee Beans

• Set a cup on your scale and tare it. Measure 57 grams of whole bean coffee.
• Pro Tip: Cold brew is forgiving, so you don’t necessarily need the freshest beans. Even coffee that’s 3 or 4 weeks old will still taste great.

1. Grind The Coffee Very Coarsely

• Grind your coffee beans to a coarse size, similar to breadcrumbs. This is coarser than what you would use for French press coffee.
• Add the coarsely ground coffee beans to the Mason jar.
• Pro Tip: Most pre-ground coffee is too fine, leading to over-extraction and bitterness, and making it harder to filter out the grounds later.

1. Add Water And Stir

• Pour your room-temperature water over the coffee in the jar. Using a paddle or spoon, gently stir to ensure all the grounds are wet.
• Pro Tip: Use filtered water if your tap water isn’t high-quality, as good water is essential for good coffee extraction.

1. Let The Coffee Steep For 12 – 24 Hours

• Allow the coffee to steep for 12 to 24 hours. The longer it steeps, the stronger the brew will be. Personally, 20 hours is ideal, but you can adjust based on your taste.
• Pro Tip: You can steep the coffee in the fridge or at room temperature. If steeping at room temperature, keep the jar away from light, such as in a cupboard.

1. Strain The Coffee

• Set a mesh strainer lined with cheesecloth on top of an empty container. After steeping, pour the coffee through the strainer to separate the grounds.
• Pro Tip: If you don’t have a mesh strainer, secure a few layers of cheesecloth over the Mason jar with elastic bands and pour the coffee through it into a waiting container.

1. Optional: Strain Again Using A Paper Filter

• For a cleaner cup, strain the cold brew a second time through a paper coffee filter.
• Pour the cold brewed coffee back into the jar through a paper filter. This may take a while.
• Pro Tip: Use an Aeropress to force the coffee through the filter faster.

1. Dilute The Concentrate And Enjoy!

• When ready to drink, dilute the coffee concentrate with cold water. Start with a 1:2 ratio of coffee to water. Adjust to your taste preference.
• Pro Tip: To keep your cold brew from getting diluted by ice, make coffee ice cubes by freezing brewed coffee in an ice cube tray.

By following these steps, you can enjoy a refreshing cold brew coffee made right in a Mason jar. Enjoy your perfectly brewed cup!
