Flavored cold brew is coffee steeped in cold water, strained, then served over ice with milk or water and a flavoring of your choice. This recipe makes a smooth concentrate and four different drinks—vanilla, maple cinnamon, mocha, and orange cardamom—so you can mix one flavor or make an assorted batch.
Ingredients
- 1 cup (85 g) coarsely ground coffee
- 4 cups (950 ml) cold, filtered water
- 2 cups (480 g) ice, for serving
- 2 cups (480 ml) cold water or milk, for diluting the concentrate; use dairy or an unsweetened plant-based milk as preferred
- For one vanilla cold brew: 1 tablespoon (15 ml) maple syrup and ¼ teaspoon (1 ml) vanilla extract
- For one maple-cinnamon cold brew: 1 tablespoon (15 ml) maple syrup and ⅛ teaspoon (0.3 g) ground cinnamon
- For one mocha cold brew: 1 tablespoon (5 g) unsweetened cocoa powder, 1 tablespoon (15 ml) hot water, and 1 tablespoon (15 ml) maple syrup
- For one orange-cardamom cold brew: 1 tablespoon (20 g) orange marmalade and ⅛ teaspoon (0.3 g) ground cardamom
The four flavor combinations are each sized for one drink, which lets you make four different servings from the same batch. To make a whole batch of one flavor, multiply that option’s flavoring quantities by four. The listed dilution is flexible: use water for a lighter, coffee-forward cup or milk for a creamier one.
Instructions
- Grind and measure the coffee. Use a coarse grind, similar in texture to raw sugar or cracked pepper. If buying ground coffee, choose a coarse setting rather than espresso or standard drip grind. Fine grounds can pass through the filter and make the concentrate cloudy or gritty.
- Combine coffee and water. Add the grounds and 4 cups (950 ml) cold water to a clean, covered jar or pitcher. Stir gently until all of the coffee is wet. Cover the container. A jar is convenient for stirring, while a pitcher with room for a filter makes pouring easier.
- Steep in the refrigerator for 16 hours. Keep the covered mixture chilled for the full steep rather than leaving it on the counter. This slow extraction develops the coffee flavor without heating the water. If you prefer a milder concentrate, you can steep it for 12 hours; for this recipe, use the same 16-hour timing each time so the four drinks are consistent.
- Strain the concentrate. Pour the mixture through a fine-mesh sieve lined with a paper coffee filter or clean, tightly woven cloth into a second clean container. Let it drain without squeezing the grounds, which can push sediment into the coffee. If the first pour looks cloudy, strain it once more through a fresh paper filter. Allow a few extra minutes for a paper filter to drain slowly.
- Mix the flavorings. For vanilla, stir the maple syrup and vanilla extract together in a glass. For maple cinnamon, mix the syrup with the cinnamon, breaking up any small clumps. For mocha, whisk the cocoa with the tablespoon of hot water until smooth, then stir in the maple syrup; dissolving the cocoa first helps prevent dry pockets in the cold drink. For orange cardamom, stir the marmalade and cardamom together until evenly combined.
- Assemble four drinks. Put one flavor mixture in each of four glasses. Add ¾ cup (180 ml) cold brew concentrate to each glass and stir well. Add ½ cup (120 ml) cold water or milk to each, adjusting to taste, then fill the glasses with ice. The orange marmalade may take an extra few stirs to disperse; that is normal. Taste each drink before serving and add a splash more water or milk if the coffee is stronger than you like.
The concentrate is intentionally stronger than ready-to-drink coffee because each glass gets diluted as it is assembled. The exact yield varies with the grind and filter because coffee grounds hold on to some of the steeping water. If your strained batch comes up short of 3 cups (710 ml), make slightly smaller drinks or add a little more water or milk rather than changing the flavoring ratios.
Tips
- Keep the grind coarse. A fine grind makes filtering slower and can leave a dusty finish. If you only have finely ground coffee, use a paper filter and pour slowly; expect a less clear concentrate, and avoid squeezing the grounds.
- Choose coffee you enjoy drinking black. Medium or dark roasts give a familiar, rounded coffee taste, while a lighter roast can taste brighter and more fruit-like. Freshly ground beans are convenient, but good-quality pre-ground coarse coffee also works.
- Adjust sweetness and dairy separately. Start with the quantities listed, then add a little more maple syrup if needed. For dairy-free drinks, oat, soy, almond, or coconut milk can be used; each changes the texture and flavor slightly. Unsweetened versions make it easier to control the final sweetness.
- Keep flavorings smooth. Cinnamon and cocoa can clump when added straight to cold coffee. Mix them first with syrup or a small amount of warm water. Marmalade gives the orange drink a gentle citrus note and a little texture; for a smoother result, stir it into the concentrate and strain the finished drink through a small sieve.
Serving Suggestions
Serve the drinks freshly mixed in tall glasses with plenty of ice. Vanilla cold brew works well with dairy milk or oat milk and can be topped with a light dusting of cinnamon. Maple cinnamon is especially good with a splash of milk, which softens the spice while keeping the maple flavor noticeable. For the mocha, use milk for a more rounded, chocolate-forward drink, or water if you prefer to keep the coffee more prominent.
Orange cardamom is a good choice for a brighter, aromatic cup. Stir it thoroughly before drinking so the marmalade does not settle at the bottom. A strip of orange peel can be used as a garnish, but avoid adding a thick piece of pith, which can taste bitter. For a group, set out the concentrate, ice, water, milk, and small bowls of the flavorings so everyone can customize a glass. Keep the concentrate chilled while people serve themselves.
Variations
These four flavorings are starting points, not a fixed set. For a less sweet vanilla drink, omit the maple syrup and add a little extra milk; vanilla extract alone adds aroma but not sweetness. Replace the maple syrup in the cinnamon version with honey if you like its floral taste, or leave out the spice for a straightforward maple cold brew. Maple syrup dissolves readily in a cold drink, which is why it is used here instead of granulated sugar.
To change the mocha, use Dutch-process cocoa for a darker, less sharp chocolate note, or add a pinch of ground cinnamon to the cocoa mixture. Cocoa powder gives the drink a gently chocolatey flavor rather than the sweetness of chocolate syrup; add more maple syrup if you want a sweeter result. If you do not have orange marmalade, use 1 tablespoon (15 ml) orange syrup and the same pinch of cardamom. Orange syrup makes a smoother, sweeter drink, while marmalade contributes a little citrus peel and texture.
You can also make a simple spiced version by adding a pinch of cinnamon or cardamom directly to the syrup before mixing it with the concentrate. Avoid adding large amounts of ground spice to the whole steeping jar: it can settle into the coffee and make the finished batch difficult to filter cleanly. For a more intense coffee flavor, use less dilution in each glass; for a milder drink, add more water or milk. These adjustments change the strength without requiring a new batch of concentrate.
Storage and Reheating
Keep the strained concentrate in a clean, covered container in the refrigerator and use it within 4 days for the best flavor. Refrigerate it promptly after straining, and do not leave the coffee or finished drinks at room temperature for more than 2 hours. Store the concentrate separately from milk, ice, and flavorings so it stays fresh longer and does not become diluted.
Once mixed with milk or a flavoring, a cold brew is best served right away. If you have a leftover finished drink, cover and refrigerate it promptly, then drink it within 24 hours; ice will melt and soften the flavor. Cold brew is served chilled, so reheating is not needed. If you want a hot drink, gently warm a portion of the plain concentrate and dilute it with hot water or milk, rather than heating a glass with ice or leaving a prepared milk drink out.
Frequently Asked Questions
Can I steep cold brew at room temperature?
Refrigerator steeping is the method used here because it keeps the mixture chilled throughout the long extraction. If you use another method, follow its instructions and refrigerate the strained coffee promptly. For a predictable result with this recipe, keep the covered jar in the refrigerator for 16 hours.
Is cold brew concentrate ready to drink?
It can be, but this recipe is designed to be diluted. Start with equal parts concentrate and water or milk, then adjust each glass to your taste. The ¾ cup concentrate to ½ cup dilution ratio makes a fairly coffee-forward drink, and ice will soften it as it melts.
Can I use regular ground coffee?
Yes, but grind size matters. Coarse-ground coffee is easier to strain and gives a cleaner cup. If your coffee is ground for a drip machine, use a paper filter and expect filtration to take longer. Very fine espresso grounds are not ideal because they can pass through a sieve and make the drink silty.
Why does my cold brew taste weak or bitter?
A weak drink may need less dilution, a longer steep, or a more generous amount of coffee next time. A bitter or harsh taste can come from an overly fine grind, squeezing the grounds, or steeping much longer than the recipe calls for. Check that your refrigerator is cold and use the same grind and steeping time when you want a repeatable batch.
Can I make the concentrate ahead for a gathering?
Yes. Strain it, cover it, and keep it refrigerated for up to 4 days. For easy serving, prepare the flavorings shortly before guests arrive and let everyone combine a flavor with concentrate, dilution, and ice in their own glass. Do not mix a large pitcher with ice in advance, because melting ice will water it down.
Can I make a decaf version?
Yes. Use coarse-ground decaffeinated coffee in the same quantity and follow the same steeping, filtering, and mixing steps. Decaf beans vary in roast and flavor, so taste the concentrate before adding the flavorings and adjust the water or milk in each serving to suit it.
