What is the cold brew coffee powder-to-water ratio?

For cold brew, the standard starting ratio is 1:10 coffee grounds to ice water. A working batch uses 50 g of ground coffee with 400 ml of room-temperature water and 100 g of hard ice cubes, sealed and left in the refrigerator for 12 to 14 hours. Grind slightly finer than pour-over, about 80 percent passing a No. 20 standard sieve.

Low temperature and long contact time mean only small-molecule floral and fruity notes are extracted, while smoky, larger-molecule compounds are not, so cold brew tastes mild and sweet with a bright mouthfeel. After brewing, filter the grounds out with paper or a mesh and drink or refrigerate. Knowing how to prepare coffee powder at the right coarseness keeps the batch from turning bitter.

Cold brew coffee has always been deeply loved by coffee enthusiasts. Cold brew coffee is easy to make and can be prepared without any difficulty at home or in the office. This time Front Street Coffee will talk about the brewing ratio for cold brew coffee and introduce three ways to make cold brew.

The Extraction Principle of Cold Brew Coffee

Cold brew coffee is produced by mixing coffee grounds and ice water in a certain ratio and then slowly extracting. Coffee made with the cold brew process has a lower sourness and astringency. The low-temperature conditions and the long contact time with the coffee grounds allow only small-molecule flavor substances to be extracted, such as floral and fruity notes, while larger-molecule flavor substances, such as smoky notes, are difficult to extract.
 

What are the flavor characteristics of cold brew coffee?

Low-temperature extraction and long extraction time are the two major characteristics of cold brew coffee, and they are also the two main differences between cold brew coffee and coffee extracted at high temperature. Coffee extracted at high temperature uses hot water to extract coffee beans, at a temperature between 85-93°C, and generally for no more than 3 minutes. Cold brew coffee itself can fully reflect the subtle flavor characteristics of coffee. Because its acidity is mild, its taste is sweet, its mouthfeel is bright, and its flavor is soft, it presents the flavor characteristics of specialty coffee origins.
  

[Directly Made with Ground Coffee Beans]

Grind size: a grind size slightly finer than pour-over coffee (80% passing through a No. 20 standard sieve)

Ratio of coffee grounds to ice water: 1:10

Equipment needed: sealed bottle & filter paper/filter mesh
 

1. Prepare 50g of Front Street Coffee Butterfly coffee beans and grind them into a relatively fine powder (80% passing rate through a No. 20 standard sieve).

2. Pour the ground coffee powder into a sealed bottle, add 400ml of room-temperature water and 100g of hard ice cubes.

3. Cover with the lid and shake evenly, then put it in the refrigerator for 12-14 hours for low-temperature slow extraction.

 4. After the time is up, use filter paper (or a filter mesh) to separate the coffee grounds. The resulting coffee liquid can be enjoyed immediately, or it can be refrigerated and consumed within 48 hours.

[Made with Drip Bags]

Materials needed: Front Street Yirgacheffe coffee drip bags, a sealed bottle, ice-water mixture

Coffee-to-water ratio: 1:10 (the net content of one FrontStreet Coffee drip bag is 10g)
 

1. Prepare a clean sealed container with a lid, tear open the outer packaging bag, take out the drip bag inside, tear open the opening of the drip bag, pour the coffee powder from the drip bag directly into the container, and keep the drip bag as a filter after extraction is completed.

2. The coffee-to-water ratio for cold brew coffee is 1:10. The net content of one drip bag is 10g, so prepare 100ml of ice water and pour it into the container.

3. Cover with the lid and shake evenly, then put it in the refrigerator for low-temperature extraction for 12-14 hours.

4. (After extraction is completed) Take out the drip bag, open its ears and hook it onto your favorite cup, then pour the cold-brewed coffee through the drip bag to filter out the coffee grounds, and it is ready to enjoy.

[Made with Cold Brew Packs]

Materials needed: cold brew coffee packs made from Front Street Strawberry Candy, a sealed wide-mouth bottle/cup, ice-water mixture

Coffee-to-water ratio: 1:10 / 1:6 (the net content of one FrontStreet Coffee cold brew pack is 10g)
 

1. Take out the Strawberry Candy coffee cold brew pack and lift up the string.

2. Place it into a cup/bottle. It is recommended to extract at a ratio of 1:10 per pack (one cold brew pack is 10g, add 100g of cold water; this is the ratio for drinking directly after extraction is completed), or it is recommended to extract at a ratio of 1:6 per pack (one cold brew pack is 10g, add 60g of cold water; this is the ratio for mixing the extracted coffee liquid with other drinks).

3. Cover with the lid, shake a little, and place it in the refrigerator to extract for 8-12 hours so that the coffee powder fully contacts the cold water.

4. After cold brew is completed, take out the cold brew pack and enjoy.
