Your French press is secretly a great cold brew maker. Coarse coffee steeps in cold water overnight, and the plunger filters it in seconds. The result is a smooth, chocolatey, low-acid concentrate that keeps in the fridge for a week.
Here is the cold brew French press method we use.
The Short Answer
Stir 85 g (about 1 cup) of coarsely ground coffee into 680 g (about 3 cups) of cold, filtered water, a 1:8 ratio. Cover and refrigerate for 12 to 18 hours. Press slowly, pour into a jar, and dilute 1:1 with water or milk over ice.
What You Need
- A 34 oz French press.
- Coarse ground coffee. A conical burr grinder on its coarsest setting is ideal.
- Cold, filtered water.
- A jar or pitcher for storing, such as the clear glass jug.
- A tall glass; we love a glass cup with lid and straw for iced coffee.
Step by Step
Step 1: Grind coarse
Grind 85 g of beans very coarse.
Step 2: Combine
Add the coffee to the press, pour in 680 g of cold water, and stir so every ground is wet.
Step 3: Steep cold
Set the lid on without pressing and refrigerate for 12 to 18 hours.
Step 4: Press and store
Press slowly, pour the concentrate into a clean jar, and refrigerate for up to 7 days.
Step 5: Serve
Mix equal parts concentrate and water or milk over ice.
Tips for Smoother Cold Brew
- Double filter through a paper filter for an ultra-clean cup.
- Medium and dark roasts give the chocolatey flavor most people love.
- Steeping longer than 20 hours can taste woody.
- Freeze leftover cold brew in ice cube trays so iced coffee never gets watery.
Equipment I Used
- Stainless steel measuring cups and spoons: for sauces and spice blends.
- Large airtight food storage container: for leftovers and freezer portions.
