Delicious Cold Brew in a Jar

I’ve been trying to work on a cold brew method that is simple, fairly quick and produces a delicious cup of coffee. 

Some people get a little confused when we talk about cold brew. It isn’t the famous cold drip. With cold brew coffee, the ground coffee is submerged in water for a period of time (normally between 12-24 hours). With cold drip, the water slowly drips through the ground coffee over a period of time. In my opinion, both processes are great but the cold brew method is easier and more delicious. You get a complex and sweet cup. 

The only thing I do differently is that I double filter my cold brew. My first filtration is through a metal filter. This takes out most of the coffee grinds (course sludge). Then I put it through a second filter. This is a paper filter. The paper filter takes out all of the finer grinds, leaving you with a super clean and sweet cup.

  • Brewer Tip 1: You don’t need to use a filter roast. Some espresso roasts taste great through a cold brew.

  • Brewer Tip 2: The same coffee brewed hot and brewed cold will taste different.  


What you will need:

  • Jar
  • V60 filter paper
  • ABLE metal filter
  • Filtered water
  • Freshly ground coffee
  • Goose neck kettle
  • Scale
  • Cup

My Method:

  1. Grind 68 grams of coffee to the coarseness of table salt (experiment with your grind size if you want).
  2. Add 800 mLs of room temperature water to your jar. Use filtered water if possible. 
  3. Add your ground coffee to the water.
  4. Add 200 mLs of water to the jar to submerge all the ground coffee. You should now have 1 litre of water.
  5. Put a lid on the jar. Place the jar in a dark spot where the temperature will stay stable.
  6. Let it brew for 18 hours. (Brew time can be adjusted, but I suggest nothing less than 12 hours and nothing more than 24 hours).
  7. Now for the double filtration. Pour the jar of cold brew into the metal filter. This part takes out the majority of the coffee sludge so that when you use the paper filter, it doesn’t clog up too quickly.*
  8. Once the coffee has passed through, use a paper filter (V60) and filter the coffee a second time. Make sure you rinse the paper filter before filtering so you remove the paper taste.
  9. Once the coffee has passed through the paper filter you should have a delicious cup of cold brew.
  10. Add a few ice cubes or some lemonade to serve. 

* If you don’t have a metal filter, you can use the paper filter. It will just take a lot longer to filter through because of the coffee sludge. 


All my methods are straightforward and simple. I hope they give you an understanding to brew better coffee to the taste you like.
