1-First Step: Gather your mise en place Measure out 1 cup coarsely ground coffee beans into a large mason jar or pitcher. Use fresh beans ground coarse like kosher salt to avoid over-extraction. Pour in 4 cups cold filtered water. This ratio (1:4) gives a strong concentrate perfect for diluting over ice.

2-Second Step: Mix and steep Stir the coffee and water vigorously for 30 seconds until fully saturated, no dry clumps. No heat involved, keeping acidity low. Seal the jar tightly and place in the fridge. Let steep for 12-24 hours; 18 hours hits the sweet spot for balanced flavor. Longer steep means bolder taste, shorter for milder iced coffee.

3-Third Step: Strain the brew Remove from fridge. Line a fine-mesh sieve with cheesecloth, coffee filter, or paper towel over a bowl. Pour the mixture slowly, pressing lightly on grounds if needed. For ultra-smooth results, strain twice. Discard grounds. You now have cold brew concentrate ready for iced coffee.

4-Fourth Step: Dilute and sweeten Mix 1 part concentrate with 1 part water or milk for your serving. Sweeten while cool with simple syrup (equal parts sugar and hot water, cooled). Proportions: Start with 1/2 cup concentrate, 1/2 cup water, 1-2 tbsp syrup. Adjust for strength.

5-Final Step: Serve over ice Fill a tall glass with ice cubes. Pour the diluted iced coffee over. Garnish with a splash of milk or cinnamon. Serve immediately for peak chill and flavor. Pairs great with breakfast or as an afternoon pick-me-up.
