- Prepare Filter Basket: Unscrew the bottom cover of the filter basket.
- Add Coffee Grounds: Fill the filter basket with coarse ground coffee. Refer to the markings on the filter for recommended ratios (e.g., 120g for a 1:10 ratio for extra bold flavor). Securely screw the bottom cover back onto the filter basket.
- Place Filter in Pitcher: Insert the filled filter basket into the pitcher.
- Add Cold Water: Pour cold, filtered water into the pitcher, ensuring the coffee grounds in the filter are fully submerged. Fill up to the MAX 40OZ/1200ML line.

Operating Instructions
- Brewing: Place the assembled cold brew coffee maker in your refrigerator. For optimal infusion, it can be stored on its side. Allow the coffee to steep for 12 to 24 hours, depending on your desired strength.
- Coffee-to-Water Ratio: The filter basket has markings for different coffee ground amounts (e.g., 120g, 100g, 80g, 60g) to achieve varying concentrations. Experiment to find your preferred strength.
- Serving: Once brewing is complete, unlatch the lid and carefully lift the filter basket out of the pitcher. The filter basket can be temporarily rested in the lid's designated slot to prevent drips.
- Enjoy: Pour your freshly brewed cold brew concentrate over ice, dilute with water or milk, and enjoy.
