When it comes to brewing the perfect cup of cold brew coffee, the ratio of grounds to water is key. Depending on your desired strength and flavor profile, you’ll want to adjust this ratio accordingly. Generally speaking, a good starting point for those just getting into making their own cold brew at home is 1:4 – that is, one part ground coffee beans to four parts cold water (by weight). This will yield a smooth but bold-tasting concentrate that can be diluted with additional water or milk prior to serving. To make an even lighter cup of coffee, increase the amount of water used in relation to grounds; conversely, if you prefer a strong cup of joe with more caffeine kick then reduce the amount of water relative to grounds. Ultimately though, experimenting with different ratios and adjusting them as needed will help you hone in on your ideal recipe for delicious and refreshing homemade cold brew!
