Homemade Cold Brew Coffee Recipe

Smooth, refreshing, and wonderfully easy to make, homemade cold brew coffee is one of those recipes that proves you don’t need complicated equipment to create coffee-shop-worthy drinks at home.

Unlike traditional iced coffee, which is generally brewed hot and then cooled, cold brew is made by steeping ground coffee in cool or room-temperature water for many hours. The slow extraction creates a noticeably different flavor profile and is commonly associated with a smoother, less bitter cup. Research has also found measurable differences between hot- and cold-brewed coffee, although factors such as roast level and brewing method significantly affect the final result.

The best part? Once you make a batch, you can keep it chilled and turn it into everything from a simple glass of cold brew over ice to creamy lattes, vanilla cold brew, or an indulgent cold foam cold brew.

☕ Homemade Cold Brew Coffee Recipe

Prep Time: 5 minutes
Steeping Time: 12–18 hours
Straining Time: 5 minutes
Yield: About 4 cups
Difficulty: Easy

Ingredients

1 cup coarsely ground coffee, approximately 90–100 grams
4 cups cold or room-temperature filtered water
Ice, for serving
Milk or cream, optional
Simple syrup, maple syrup, honey, or another sweetener, optional

Equipment

You don’t need a special machine to make cold brew. Gather:

Large glass jar, pitcher, or French press
Measuring cup
Long spoon
Fine-mesh strainer
Cheesecloth, clean coffee filter, or nut-milk bag for finer filtering
Covered container or bottle for storing the finished coffee

A dedicated brewer can certainly make the process more convenient. If you’re considering one, see our guide to choosing a cold brew coffee maker.

🧊 How to Make Cold Brew Coffee

1. Coarsely Grind the Coffee

Start with coffee beans ground to a coarse consistency, similar to what you might use for a French press.

A coarse grind is particularly useful for long immersion brewing and makes the finished coffee easier to filter. Starbucks’ cold-brew brewing guidance likewise recommends coarse-ground coffee for this method. (Starbucks)

2. Combine the Coffee and Water

Place the ground coffee in your jar or pitcher.

Slowly pour the filtered water over the grounds, making sure they are thoroughly saturated.

Give everything a gentle stir. You don’t need to aggressively mix the coffee; just make sure there aren’t large pockets of dry grounds floating on top.

3. Let the Coffee Steep

Cover the container and allow the coffee to steep for 12 to 18 hours.

You can brew it in the refrigerator, or begin the extraction at cool room temperature and refrigerate it afterward. Cold-brew recipes commonly use an extended immersion period, often somewhere around 10–20 hours. (Food Network)

For your first batch, about 14–16 hours is a good starting point.

Then experiment.

A shorter steep may taste lighter and brighter, while a longer extraction can produce a stronger, more intense coffee.

4. Strain the Cold Brew

Pour the mixture through a fine-mesh strainer into a clean container.

For especially smooth coffee, strain it a second time through cheesecloth or a coffee filter.

Avoid squeezing or pressing the grounds excessively. Allowing the liquid to drain naturally helps keep fine sediment out of the finished brew.

5. Chill

Cover the strained cold brew and refrigerate it until thoroughly chilled.

If it was brewed in the refrigerator, you can move straight to serving.

6. Pour Over Ice and Enjoy

Fill a tall glass with ice and pour in the cold brew.

Taste it before adding anything else.

If it is stronger than you prefer, simply add some cold filtered water. Cold-brew concentrates are often diluted with water or milk before serving, and the dilution can be adjusted according to personal taste.

Finish it with milk, cream, sweetener, or your favorite flavored syrup.

🌱 What Coffee Is Best for Cold Brew?

There isn’t one single “correct” coffee for cold brew.

Your choice of beans will dramatically change the personality of the drink.

Medium roast is an excellent place to begin. It often provides the balanced chocolate, caramel, toasted nut, and traditional coffee flavors many people enjoy in cold brew.

Dark roast can produce a deeper, bolder drink that stands up particularly well to milk and cream.

Light roast is worth trying if you enjoy more distinctive fruit, floral, or bright flavors.

💧 Why Filtered Water Makes a Difference

Coffee is overwhelmingly water, so the flavor of your water becomes part of the flavor of your finished drink.

If your tap water tastes strongly of chlorine, minerals, or other flavors, those characteristics may come through in the coffee.

Cold filtered water is an easy choice for consistently good homemade cold brew.

🥛 Delicious Ways to Serve Homemade Cold Brew

Once you’ve mastered the basic recipe, cold brew becomes an incredibly versatile base for other coffee drinks.

Try serving it:

Classic: Cold brew poured over plenty of ice.
Creamy: Add a splash of whole milk, half-and-half, oat milk, or almond milk.
Vanilla: Stir in vanilla simple syrup.
Caramel: Add caramel syrup and a little milk.
Mocha: Mix with chocolate syrup and cream.
Maple: Sweeten lightly with pure maple syrup.
Cinnamon: Add cinnamon syrup or a light sprinkle of ground cinnamon.
Coconut: Serve with coconut milk for a tropical twist.
Cold Foam: Top it with creamy foam using our cold foam cold brew recipe.

You can also pour cold brew into an ice cube tray and freeze it. Use those coffee cubes instead of ordinary ice so your drink doesn’t become watered down as the cubes melt.

🍯 How to Sweeten Cold Brew Coffee

Granulated sugar does not dissolve particularly well in an already-cold drink.

For that reason, simple syrup is one of the easiest cold-brew sweeteners.

Make a basic simple syrup by combining equal quantities of sugar and hot water and stirring until the sugar dissolves. Cool it completely before adding it to your coffee.

You can also experiment with:

Vanilla syrup
Brown sugar syrup
Maple syrup
Honey syrup
Caramel syrup
Chocolate syrup
Cinnamon syrup

Start with a small amount and add more as needed. Cold brew can be naturally pleasant on its own, and you may find that you need less sweetener than expected.

📏 How Strong Should Cold Brew Be?

There is no universal cold-brew ratio because some recipes create a beverage intended to be consumed directly while others create a concentrated coffee that is diluted before drinking.

Starbucks, for example, gives a cold-brew guideline of about 22 grams of coarse-ground coffee per 180 milliliters of water, while other recipes and commercial brewing systems vary substantially.

That flexibility is part of what makes homemade cold brew so enjoyable.

Use the recipe here as your starting point, then adjust future batches:

For stronger cold brew:
Use slightly more coffee.

For milder cold brew:
Use a little more water or dilute the finished coffee.

For a concentrate:
Increase the proportion of coffee and dilute each serving with cold water or milk.

Writing down your coffee amount, water amount, grind, and steeping time makes it surprisingly easy to discover your personal perfect recipe.

🚫 Common Cold Brew Mistakes

Grinding the Coffee Too Fine

Very finely ground coffee can make the finished cold brew muddy and difficult to filter.

Use a coarse grind instead.

Not Saturating All the Coffee

Dry clumps prevent the water from evenly contacting the coffee grounds.

Stir gently immediately after adding the water.

Steeping Forever

Longer isn’t automatically better. An excessively long extraction can produce flavors you may find woody, heavy, or unpleasant.

Start around 12–18 hours and adjust from there.

Using Coffee You Don’t Like

Cold brewing can’t magically transform unpleasant beans into amazing coffee.

Start with coffee whose roast and general flavor profile you already enjoy.

Forgetting That You Can Dilute It

If your first sip tastes overwhelmingly strong, the batch isn’t ruined.

Add water, milk, or ice until the strength is right for you.

🧊 Cold Brew vs. Iced Coffee: What’s the Difference?

Although people sometimes use the terms interchangeably, cold brew and iced coffee are not the same brewing method.

Traditional iced coffee generally begins as coffee extracted with hot water and is subsequently chilled or served over ice. Cold brew extracts the coffee using cool water over a much longer period.

That difference in extraction affects aroma, flavor, acidity, bitterness, and other sensory characteristics. Controlled research has found that brewing temperature can produce noticeable sensory differences between cold brew and chilled hot-brewed coffee.

Neither method is inherently “better.” They simply create different styles of coffee.

❓ Frequently Asked Questions

Can I make cold brew without a cold brew maker?

Absolutely. A glass jar or pitcher and a strainer are enough.

A French press also works particularly well because the built-in plunger makes separating the grounds easy.

Can I use regular ground coffee?

You can, but standard pre-ground coffee is often finer than ideal.

Coarsely ground beans usually make filtering easier and help reduce sediment.

Does cold brew have more caffeine?

Not necessarily.

Caffeine content depends on the type and quantity of coffee, water ratio, extraction conditions, dilution, and serving size. Because cold-brew concentrates may use substantially more coffee per unit of water, some servings can contain a lot of caffeine—but the term “cold brew” alone doesn’t tell you how caffeinated a particular drink will be.

Can I make decaf cold brew?

Yes! Simply substitute your favorite decaffeinated coffee beans and follow exactly the same process.

Do I have to drink cold brew black?

Not at all.

Milk, oat milk, cream, vanilla, caramel, chocolate, maple, cinnamon, and cold foam all work beautifully with cold brew.

Can cold brew be served hot?

Yes. Cold brew refers to the brewing process, not necessarily the serving temperature.

You can dilute cold-brew concentrate with hot water for a smooth hot coffee drink.

☕ A Simple Coffee Recipe Worth Making Again and Again

Homemade cold brew is remarkably simple: coffee, water, time, and a little patience.

Once you’ve made your first batch, the possibilities multiply. Drink it black over ice, add a splash of cream, turn it into an iced latte, top it with cold foam, or create your own flavored coffee-shop drink.

Best of all, you control the beans, strength, sweetness, and serving style.

Prepare a batch tonight, and tomorrow’s refreshing glass of cold brew will already be waiting in the refrigerator.
