Summer in Berlin can get quite hot, and what's better than enjoying a refreshing cold brew on ice on a sunny day on your balcony? So, why not try making cold brew at home? In this blog post, we'll show you how to make cold brew using simple household ingredients.

Cold brew is a coffee preparation method in which coarsely ground beans are extracted with cold water for an extended period of time—usually 12 to 24 hours. This cold brewing process ensures that the coffee is less bitter than hot brews, while still developing a refreshingly smooth and natural sweetness. For many coffee lovers, cold brew is therefore a welcome alternative to classic coffee specialties in the summer.

If you want to make cold brew at home, you don't need much, just the right ingredients and the right technique. Here's a simple and refreshing recipe you can try in your Berlin kitchen.

And here's how it works:

Grab 70g of freshly ground coffee beans (for about 1 liter of cold brew). We recommend light-roasted, fruity beans (e.g., Sidamo Acacia or Finca Medina ), 1 liter of cold water, and a large jar, glass, or container.

• Grind the coffee: Grind 70g of coffee beans fresh and coarsely. The grind should be like coarse sea salt to prevent the cold brew from becoming too bitter.
• Mixing coffee with water: Place the ground beans in a container (e.g., a large glass or pitcher) and add 1 liter of cold water ( make sure the water quality is correct ). Stir well so that all coffee particles come into contact with the water.
• Steep: Now let the mixture steep in the refrigerator for 12 to 24 hours—depending on your preference. The extraction process is slower than with hot coffee, but that's precisely what makes cold brew so smooth.
• Filtering: After the cold brew has steeped, you need to filter the coffee to remove any remaining coffee grounds. You can use a coffee filter, a fine mesh strainer, or a special cold brew filter set.
• Now, sip! Pour your homemade cold brew into a glass with ice cubes, sit back, and enjoy summer in the capital!

Is cold brew too boring for you? Just add tonic water. Cold Brew Tonic tastes fresh, slightly bitter, and a bit like a coffee cocktail—tart from the coffee, tangy from the tonic, overall quite dry and super refreshing, with a tingling mouthfeel and a clean, almost lemony finish.
