FAQs

How much coffee do I need for overnight cold brew? ›

A ratio of 1:8 of coffee to water will produce a nice coffee ready to drink after around 24 hours at a coarse grind. Another option is to create a much stronger cold brew (named cold brew concentrate), by using a ratio anywhere from 1 part coffee to 4 parts water, up to around 1 part coffee to 2 parts water.

Anything beyond 24 hours is going to be over-extracted and bitter, tasting of wood. Not necessarily the tasting notes you're looking for. Luckily, cold brew is much more forgiving than its hot counterpart.

The best part about making cold brew at home is you can dial it in to your personal taste. Somewhere in the 16 to 20 hour range is the sweet spot for most coffees. We're willing to bet you'll find your favorite steep time right in there somewhere. Start with a 16-hour batch, taste, and go from there.

Batch Brew Coffee Ratio

It couldn't be simpler to give you a recipe to try for batch brewing. We tend to see the least error in brewing, and the least negative results when recipes are simply kept to 60g coffee per litre of water added.

Larger pour-over brewers, such as the 6 to 10-cup Chemexes, are ideal for batch brewing. Kaley says that with the Chemex, you should start with a brew ratio somewhere between 1:14 and 1:17. “If you're using a Chemex and scaling up the brew size, add more coffee to fit that ratio and then coarsen the grind,” she says.

For cold brew, you want to aim for a coffee to water ratio around 1:6. It's easiest to measure this by weight, so grab a kitchen scale if you have one. For example, if we want a liter of cold brew (1000ml or ~32 ounces), we'd weigh out 167 grams of coffee.

The beauty of Cold Brew is you really don't need anything fancy, just time. Stick with a coarse grind. Using a coarser grind will make the filtration process easier and your coffee taste far less bitter. Grinding too fine can heat up the grounds, which can negatively affect your cup.

To make cold brew coffee, coarse coffee grounds are immersed in water for a minimum of eight—and up to 24—hours. It's different to the process of making drip coffee where hot water passes through the coffee grounds, dissolving the coffee and water together as it falls into a carafe, says Rounds.

Research shows that with increased coffee and cold brew consumption, you can reduce the risk of some cancers, heart disease as well as type-2 diabetes, Parkinson's and Alzhimer's disease. For heart disease, studies show that drinking 3-5 cups of coffee per day may lower your risk of heart disease by up to 15%.

Do you let cold brew steep in the fridge? ›

If you soak the grinds for just 12 hours you'll find a cold brew that is weak and somewhat astringent, but after about 18 hours the brew is super smooth. Stick it in the fridge: Use cold water (filtered, if you want to really get specific) and let the brew sit in the fridge for 18 to 24 hours before straining.

This will ensure that the coffee is incorporated with the water fully, rather than rising to & sitting at the top while off-gassing. If possible, stir again at the 12 hour mark; this isn't necessary, but we find it works best if you do.

If you find your cold brew to be a little bitter, it's likely that the concentrate was over extracted by too much time or too fine of a grind. For immersion, you can reduce the brew time or use a coarser grind. For slow drip, try a coarser grind.

This will result in a stronger, more concentrated coffee, but it may not have the smooth, rich flavor of cold brew that has been steeped for a longer period of time.

For comparison, if you make your own cold brew, your cost would be dramatically reduced, to 7.2 cents per ounce for finished product.

The recommended coffee-to-water ratio for cold brew is usually 1:8. Therefore, for 1 gallon (128 fluid ounces) of cold brew, you would need approximately 16 ounces (1 pound) of coffee grounds. However, you can adjust the amount based on your personal preference for the strength of the cold brew.

For a 5 gallon bucket, we use a 5 lb bag of coarsely ground coffee. Let it steep in the water for 20 hours. It helps to have the bag elevated off of the bottom of the bucket a little bit.

Weigh. For cold brew, you want to aim for a coffee to water ratio around 1:6. It's easiest to measure this by weight, so grab a kitchen scale if you have one. For example, if we want a liter of cold brew (1000ml or ~32 ounces), we'd weigh out 167 grams of coffee.
