These factors could be using a different method to brew coffee, or using a different coffee to water ratio, or using a different type of coffee grounds!

If you are not using the fancy method of brewing cold brew and using the good old container, mason jar, or a french press to brew your coffee, it should take you around 12 to 16 hours.

Other factors, like the temperature, coffee beans, and coffee to water ratio should be taken into consideration. But, if everything is done right you should have a good glass of Cold Brew within 12 to 16 hours of brewing your coffee.

How Long Is Too Long To Steep Cold Brew?

Most people seem to think that the longer they steep the Cold Brew, the better it will taste. Well, that is not at all the case. Overextraction can result in your coffee tasting extremely bitter and the flavor of the coffee will be way too overpowering for you to drink.

Therefore, if you were to steep the coffee grounds a little longer, we do not recommend going any longer than 24 hours at room temperature. You can steep it for a little longer in the refrigerator as the cold temperature slows down the extraction process.

What Happens If You Steep Cold Brew For Too Long?

If you steep your Cold brew longer than it is recommended (24 hours at room temperature) it means that you have over-extracted from your coffee beans. This results in an extremely bitter coffee, it also develops a woody taste.

What Happens If You Don’t Steep Cold Brew Long Enough?

Since Cold Brew is brewed without using any heat in the process, the water needs a lot of time to extract the flavors and oils from the coffee bean.

Thus, as important it is to keep a watch on over-extraction, it is also very important to make sure that you are not steeping it lesser than what is recommended. 

If you filter the coffee beans earlier than the required time, you will end up with a watery and weak coffee. That probably does not has the flavor of Cold Brew that you were expecting.

Does The Coffee Grind Size Affect Cold Brew Steeping Time?

Yes, it is extremely crucial that the right size of ground coffee has been used to make cold brew. The right type of Grind for your Cold Brew is a coarse grind, similar to the size of sugar pearls or kosher salt. 

The simple explanation to why you need to use coarse coffee grounds for cold brew is that when you use fine coffee grounds you risk over-extraction.

This happens because the grounds are so fine, that it takes a long time to filter out the water which results in over-extraction leading to an extremely bitter coffee.

What Type Of Coffee Beans Should Be Used For Cold Brew?

Coffee Beans

Most people would recommend using medium to dark roast for cold brew, as light roast would not bring out the flavor that strong coffee has. When you use Medium to dark roast you get that chocolate and nutty flavor in your coffee which makes it taste smooth and less acidic.

But, our recommendation would be to begin making your coffee with a light to medium roast. This is because Cold brew brings out a different flavor profile than hot brew credits to its long steeping hours.

Here are some of the best coffee you can use to make Cold Brew –

1. Light Roast –  LifeBoost Light Roast Beans 

2. Medium Roast –  Tiny Footprint Coffee Cold Brew & Press Elixir

3. Dark Roast –  Stone Street Cold Brew Coffee

Do You Need To Steep Cold Brew In The Fridge?

No, you do not need to steep Cold brew in the fridge. In fact, the right way to do this would be to let the coffee grounds steep on the countertop at room temperature. Once the brewing process is over filter out the coffee, and store the concentrate in the refrigerator.

The reason why you should not be brewing cold brew inside the refrigerator is that it will lengthen the extraction process at a colder temperature, therefore making it longer to be ready to drink.

How Long Does Cold Brew Last Refrigerated?

Once the brewing is complete and you have stored the coffee in the fridge. It can last anywhere between 8 to 14 days. To ensure safety, store it in an airtight container. After 2 weeks, the coffee could go rancid and lose its aroma and intensity. 

What Is The Coffee Grounds To Water Ratio?

We have found the best results with a 1:5 ratio, that is if you need to take 200gm of coffee grounds for every 1litre of water. This works best if you want to brew coffee in a way that you take it out of the jug and pour and enjoy without diluting it with more water.

But, if you’re brewing a batch of cold brew and looking to make a cold brew concentrate then follow the ratio of 1:2, for every 1 part of coffee use 2 parts water.

Most people prefer experimenting with coffee to water ratio to find out how strong they like their brew and we would recommend doing the same.

If you’re a beginner start with the given ratio and then adjust according to your taste and preferences. You can dilute the cold brew concentrate with milk, water, soda, etc.
