Make smooth, rich cold brew concentrate at home using the Toddy Cold Brew System, then serve it through a 6 Cup Chemex for a clean, bold cup.
Quick answer
Use the Toddy Cold Brew System to steep coarse-ground coffee in cold water for 12-24 hours, then filter and serve the concentrate over ice or diluted with water or milk. For a single serving, brew the concentrate through a 6 Cup Chemex to remove any fine sediment and enjoy a smooth, bold cup.
Why combine the Toddy system with a Chemex?
The Toddy Cold Brew System makes a concentrated, smooth cold brew that's perfect for iced coffee or lattes. But the concentrate can sometimes have fine coffee particles that make the last sip gritty. Pouring the concentrate through a 6 Cup Chemex with its paper filters removes those fines, giving you a cleaner, brighter cup without losing body.
Choosing the right coffee-to-water ratio
For the Toddy system, use a 1:4 ratio of coffee to water by weight for a concentrate. That means 1 cup (about 120 grams) of coarse-ground coffee to 4 cups (960 grams) of cold, filtered water. This ratio yields a strong concentrate that you can dilute 1:1 with water or milk. If you prefer a milder brew, use a 1:6 ratio. The Toddy system's non-electric design makes it easy to adjust for your taste.
Step-by-step: Toddy cold brew with Chemex serving
- Grind and combine: Grind 120 grams of coffee beans to a coarse consistency (like sea salt). Place the Toddy brewing bag in the system's brewing container, add the coffee, and pour in 960 grams of cold, filtered water. Stir gently to wet all grounds. A common mistake is grinding too fine, which can make the brew bitter and clog the filter. Stick to coarse.
- Steep at room temperature: Cover the Toddy container and let it steep at room temperature for 12-24 hours. The longer steep time extracts more flavor without bitterness. For a balanced concentrate, aim for 18 hours. Don't steep in the fridge—cold slows extraction and can lead to a weak concentrate.
- Drain and store concentrate: After steeping, remove the brewing bag and let it drain into the container. Squeeze the bag gently to extract remaining liquid. Transfer the concentrate to a sealed glass jar and refrigerate. It keeps for up to 2 weeks. Squeezing too hard pushes fine particles through the bag, which the Chemex will catch later.
- Brew a single serving through the Chemex: Place a Chemex filter in the 6 Cup Chemex and rinse it with hot water. Pour 4 ounces (120 ml) of Toddy concentrate into the Chemex. Add 4 ounces of cold water or milk for a 1:1 dilution. Let it drip through—this takes about 1-2 minutes. Pouring too fast can cause the filter to overflow. Pour slowly in a steady stream.
- Serve and enjoy: Once the liquid has passed through the filter, pour the clean cold brew into a glass filled with ice. Add sweetener or milk to taste. The result is a smooth, bold cup with no sediment. For a stronger flavor, use less water or milk. For a lighter cup, dilute further.
