Quick Answer: Create smooth, low-acid cold brew concentrate perfect for hot summer days. This make-ahead method stays fresh for up to two weeks.

Cold brew represents the opposite end of the coffee spectrum from espresso – where patience replaces pressure to create a smooth, refreshing concentrate. This low-and-slow method uses time instead of heat to extract coffee's flavors, resulting in a naturally sweet, low-acid beverage.

The extended 12-24 hour steeping process extracts different compounds than hot brewing methods, producing a concentrate that's perfect for iced drinks, mixing with milk, or diluting to taste. Cold brew is forgiving, consistent, and ideal for batch preparation.

Step by step

Step 1: Grind Coffee Coarsely

Grind 200g of coffee beans to a very coarse consistency - similar to breadcrumbs.

Step 2: Combine Coffee and Water

Add ground coffee to jar. Pour room temperature water slowly, stirring to saturate all grounds.

Step 3: Steep for 12 Hours

Cover and steep at room temperature for 12 hours, or refrigerate for up to 24 hours.

Step 4: Strain and Store

Strain through fine mesh. Store concentrate in refrigerator for up to 2 weeks.

Pro tip: Change only one variable at a time — grind, dose, water temperature, or time — so you know what improved the cup.
