NYT Cold Brew Coffee Recipe for Smooth Concentrate

This NYT-style cold brew coffee recipe makes a smooth, strong concentrate from coarsely ground coffee and cold water, steeped slowly in the refrigerator. Dilute each serving with water or milk, then pour it over ice for an easy, mellow coffee with no special machine required.

Ingredients

1 cup (85 g) coarsely ground coffee, preferably a medium or dark roast
4 cups (946 ml) cold, preferably filtered, water
For serving: 2 cups (473 ml) cold water or milk, plus more to taste
For serving: 4 cups (about 560 g) ice cubes
Optional: 2 to 4 teaspoons (10 to 20 ml) simple syrup or another sweetener, to taste

Instructions

Grind the coffee. Grind whole beans coarsely, to a texture like rough sea salt or breadcrumbs. If buying ground coffee, choose a coarse grind intended for French press; finely ground coffee is harder to filter and can make the concentrate muddy or bitter. Measure 1 cup (85 g) after grinding.
Combine coffee and water. Put the grounds in a clean, large jar or covered food-safe container. Pour in 4 cups (946 ml) cold water, stirring gently until all the grounds are wet. Some grounds may float at first; press them down with a spoon so they make contact with the water. Cover the container.
Steep in the refrigerator. Refrigerate for 12 hours. This gives the water time to extract flavor without heat. A shorter steep can taste thin, while a much longer one may become woody or overly bitter. If you prefer a more pronounced, heavier brew, steep for up to 14 hours the next time and adjust to taste.
Set up a filter. Place a fine-mesh strainer over a clean bowl or large measuring jug. Line it with a paper coffee filter, a clean thin cotton cloth, or a reusable coffee filter. Slowly pour the mixture through. Avoid pressing or squeezing the grounds: that can push fine particles into the coffee and make it cloudy.
Filter again if needed. If the strained coffee still looks gritty, rinse the strainer, line it with a fresh paper filter, and pour the liquid through once more. Paper filters usually give the cleanest cup; cloth or mesh filters are reusable but may let a little sediment through. Discard the used grounds rather than leaving them in the concentrate.
Dilute and serve. For each drink, combine ½ cup (118 ml) concentrate with ½ cup (118 ml) cold water or milk. Pour over a cup of ice and sweeten if you like. The concentrate is intentionally strong, so start with this equal-parts ratio and add more water or milk if it tastes too intense. The amount of finished concentrate can vary slightly with the grind and filtering method.

Tips

Choose coarse grounds. Coarsely ground coffee is easier to filter and tends to produce a cleaner-tasting concentrate. If you only have medium-ground coffee, it can work, but filter slowly and expect more sediment. Avoid espresso-fine grounds, which can clog a paper filter and leave a harsh, cloudy brew.
Measure by weight when possible. A cup of coffee grounds can weigh more or less depending on the bean and grind. The 85 g measurement makes the strength more consistent from batch to batch. Keep the water at 946 ml for this recipe; changing both quantities at once makes it harder to tell what adjustment helped.
Do not steep on the counter. The recipe is designed for a 12-hour refrigerator steep. Starting with cold water and keeping the covered container chilled makes the process predictable and protects the finished drink from sitting warm for an extended period.
Filter patiently and adjust the cup, not the batch. Let gravity do the work instead of squeezing the grounds. Once filtered, change the strength one glass at a time by adding water or milk. That way, the remaining concentrate stays flexible for different tastes and uses.

Serving Suggestions

Serve the concentrate diluted and poured over plenty of ice. Water lets the coffee flavor come through clearly; dairy milk gives it a rounder, softer finish, while oat, soy, almond, or other unsweetened plant milk can be used in the same amount. Because some plant milks are naturally sweet, taste the drink before adding syrup. For a bigger glass, add more ice and a splash of water rather than using the concentrate undiluted.

To sweeten evenly, stir simple syrup into the diluted coffee. Granulated sugar dissolves slowly in a cold drink, so dissolve it first in a spoonful of warm water or use a liquid sweetener. A small splash of vanilla extract, a pinch of cinnamon, or a little cocoa can add aroma without changing the basic brewing method. For a coffee-forward dessert, pour diluted cold brew over vanilla ice cream instead of serving it with ice.

Variations

Make it stronger or lighter: Keep the brewed concentrate as written and adjust the dilution in the glass. Try ⅔ cup (158 ml) concentrate with ⅓ cup (79 ml) water for a bolder drink, or use ⅓ cup (79 ml) concentrate with ⅔ cup (158 ml) water for a lighter one. These are starting points; ice melting into the drink will soften it further.

Try a different roast: Medium-roast beans give a balanced cup, while dark-roast beans usually taste more chocolatey or toasted. A lighter roast can bring brighter, fruitier notes, though it may taste sharper when served cold. Use fresh beans and keep the grind coarse; the steep time and water ratio can stay the same for a first try.

Make a small batch: Halve the recipe to use ½ cup (about 43 g) coffee and 2 cups (473 ml) water. Use a smaller jar, keep the same 12-hour refrigerator steep, and filter as directed. The smaller amount may pass through the filter more quickly, but the steep time does not need to be halved.

Add flavor after brewing: Stir a little vanilla syrup, caramel syrup, or maple syrup into an individual serving. Adding flavor to each glass lets you keep the main batch plain and control the sweetness. Avoid adding spices directly to the jar unless you are prepared to filter again; small pieces can be difficult to remove and may make the coffee taste stronger than intended.

Storage and Reheating

Transfer strained concentrate to a clean, covered bottle or jar and refrigerate it promptly, within 2 hours of preparation. For the best flavor, use it within 5 to 7 days; coffee can become flat or develop stale flavors as it sits. Keep it covered so it does not absorb aromas from other foods. If the drink has been left at room temperature for more than 2 hours, discard it rather than saving it for later.

Store the concentrate undiluted when possible, then add water or milk just before serving. This makes it easier to control each glass and helps prevent ice from watering down a whole batch. If you have already diluted the coffee, keep it covered and refrigerated and aim to drink it within a day for the best flavor. Do not return a partly finished glass to the storage container.

Cold brew is usually served cold, but it can be warmed for a hot drink. Mix one part concentrate with one part hot water or milk, then heat the diluted drink gently in a saucepan or microwave until it reaches your preferred temperature. Do not boil it; boiling can drive off aroma and make the coffee taste harsh. Heat only the amount you plan to drink.

Frequently Asked Questions

Is cold brew concentrate the same as ready-to-drink cold brew?
Not necessarily. This recipe makes a strong concentrate, which is diluted before serving. Ready-to-drink cold brew is already mixed to a drinking strength. Start with equal parts concentrate and water or milk, then adjust the next glass to suit your taste.

Can I use regular pre-ground coffee?
Yes, but a coarse grind is best. Standard pre-ground coffee is often finer, so the filter may clog and the drink may contain more sediment. Pour slowly, use a paper filter, and consider shortening the steep slightly if the finished coffee tastes too bitter. For the clearest result, use coarse-ground coffee.

Can I steep the coffee for longer than 12 hours?
You can, but longer is not automatically better. A few extra hours may make the coffee taste stronger, while an overly long steep can bring out woody or bitter flavors. Try 12 hours first, then adjust by one or two hours in a later batch. Keep the container refrigerated throughout.

Why does my cold brew taste weak or bitter?
A weak cup may come from too little coffee, a grind that is too coarse, or a steep that was cut short. Check the coffee weight and steep for the full 12 hours before increasing the amount. Bitterness can come from a very fine grind, an extended steep, or squeezing the grounds during filtering. Adjust one variable at a time.

Do I need a special cold brew maker?
No. A clean jar or covered container, a strainer, and a paper filter or clean cloth are enough. A dedicated brewer can make filtering neater, but it does not change the basic ratio or steeping method. Choose equipment that is easy to clean and large enough to hold the coffee and water with room to stir.

Can I make the concentrate with hot water?
This method uses cold water and a long refrigerated steep, so hot water changes the flavor and timing. If you want cold coffee quickly, make ordinary hot coffee and cool it over ice, understanding that it will taste different and may be diluted as the ice melts. For this recipe’s smoother, slow-steeped profile, use cold water and allow the full steep.
