5 Common Cold Brew Mistakes and How to Fix These Mistakes

Cold brew coffee is a delicious and refreshing way to enjoy your daily caffeine fix, but if it’s not strong enough, it can be a bit of a disappointment.

Whether you’re a seasoned cold brew maker or just starting, it can be frustrating to put in the time and effort only to end up with a weak, flavorless cup of coffee. So what went wrong, and how can you fix it?

Here are five common mistakes that can cause your cold brew to turn out weak and some suggestions for avoiding them.

Using Too Much Water

One of the most common mistakes people make when making cold brew is using too much water.

Cold brew coffee requires a higher coffee-to-water ratio than hot brew methods, so using too much water can dilute the flavor and make the final product weaker.

A good rule of thumb is to use about twice as much coffee as you would for hot brewing or about 1 cup of coffee per 1 quart of water.

Not Using Enough Coffee

On the flip side, using too little coffee can also result in a weak cold brew.

If you’re not using enough coffee, the flavor won’t be concentrated enough to stand up to the water, and the final product will be weak and flavorless.

Again, aim for a coffee-to-water ratio of about 1:2, and adjust based on your taste preferences.

Using Low-Quality or Old Coffee

The quality of the coffee you use can have a major impact on the strength and flavor of your cold brew. If you’re using low-quality or old beans, it’s likely that your final product will be weak and taste stale.

This is because the flavor and aroma of coffee beans can degrade over time, leading to a less vibrant and satisfying drink.

To ensure that your cold brew is as strong and flavorful as possible, it’s important to use fresh, high-quality beans. Look for beans that have been recently roasted and are sourced from reputable producers.

The extra effort and cost of investing in good beans will pay off in the form of a delicious and satisfying cold brew.

Brewing for Too Short or Too Long

The time you brew your cold brew can also affect its strength. If you brew it too short, the coffee won’t have enough time to extract all its flavors and oils, resulting in a weak, watery drink.

On the other hand, brewing for too long can lead to over-extraction and a bitter, unpleasant taste. Aim for a brewing time of about 12-24 hours for the best balance of flavor and strength.

Not Storing Properly

Finally, how you store your cold brew can also impact its strength and flavor. If you don’t store it properly, the coffee can become stale and lose its flavor.

Be sure to store your cold brew in an airtight container in the refrigerator to keep it fresh.


So there you have it – five common mistakes that can cause your cold brew to turn out weak, and some suggestions for how to fix them.

With a little trial and error, you can perfect your cold brew technique and enjoy delicious, strong coffee every time. Happy brewing!
