Cold Brew Recipes
A cold brew recipe is a specific set of measurements and timing – coffee dose, water amount, grind size, steeping time, and dilution – that produces a particular result. The brewing method (steeping coarse coffee in cold or room-temperature water for an extended period) stays the same across all of these recipes. What changes is the ratio of coffee to water, how long the coffee steeps, and whether the result is meant to be diluted before drinking.
This is the difference between a brewing method and a recipe. The method describes the process. The recipe describes the proportions and outcome – a concentrate meant to be diluted, a ready-to-drink brew meant to be served as-is, or a small single-serving batch made for one person.
Cold brew recipes vary because people use cold brew differently. Some want a strong base they can dilute and flavor throughout the week. Others want something they can pour over ice and drink immediately. Ratios and dilution are the two variables that separate these outcomes, and understanding how they work makes it straightforward to adjust any recipe to personal preference.
This page covers a set of practical cold brew recipes – standard, concentrate, ready-to-drink, small batch, and large batch – along with serving variations and flavored versions. For an explanation of the brewing process itself, see the separate Cold Brew Brewing Guide.
Understanding Cold Brew Recipes
Coffee-to-Water Ratio
The coffee-to-water ratio is the relationship between the weight of dry coffee and the weight or volume of water used to steep it, expressed as a ratio such as 1:4 or 1:8. A 1:4 ratio (one part coffee to four parts water) produces a strong concentrate intended for dilution. A 1:8 ratio produces a brew that can often be served closer to as-is, with light dilution if desired. The ratio is the single biggest factor in how strong the finished brew tastes.
Grind Size
Cold brew recipes call for a coarse grind – noticeably coarser than what is used for pour over or drip brewing. A coarse grind reduces the surface area exposed to water, which slows extraction to match the long steeping time. A finer grind extracts faster and can produce over-extracted, bitter, or muddy flavors over a 12+ hour steep, along with a cloudier, harder-to-filter brew.
Steeping Time
Steeping time for cold brew typically ranges from 12 to 24 hours. Shorter steeps (12-14 hours) produce a lighter, brighter result. Longer steeps (18-24 hours) produce a fuller, stronger result with more body. Steeping much beyond 24 hours does not generally continue to improve flavor and can introduce flat or muted notes as more bitter compounds are extracted.
Concentrate vs Ready-to-Drink
A concentrate is brewed at a strong ratio (commonly 1:4 to 1:5) and is too intense to drink without dilution. It is brewed this way intentionally – concentrate is stable, takes up less storage space relative to its strength, and can be diluted differently depending on how it will be served (over ice, with milk, or as a base for other drinks). A ready-to-drink recipe is brewed at a lighter ratio (commonly 1:8 to 1:12), so the result can be served with little or no additional dilution.
Serving Temperature
Cold brew is steeped cold but does not have to be served ice-cold. It can be served over ice, at refrigerator temperature, or even gently warmed (cold brew can be heated without the bitterness associated with reheating hot-brewed coffee, since it was never heated during extraction). Serving temperature is a separate decision from the brewing process and depends on how the finished coffee will be used.
Essential Equipment
| Equipment | Why It Is Useful |
|---|---|
| Brewing Container | Holds the coffee and water during steeping. A jar, pitcher, or French press can be used. The container should hold the full volume of water and coffee grounds with additional space available. |
| Coarse Coffee Grinder | Produces the coarse and consistent grind required for cold brew. A burr grinder set to its coarsest setting is preferred over a blade grinder, which creates uneven particle sizes. |
| Scale | Measures coffee dose and water by weight, allowing consistent brew ratios and repeatable recipes between batches. |
| Filter or Strainer | Separates brewed coffee from spent grounds after steeping. Options include fine mesh strainers, cheesecloth, or paper filters depending on the desired amount of sediment. |
| Glass Bottle or Carafe | Stores finished cold brew or concentrate in the refrigerator. Glass does not absorb odors or flavors from other foods, making it preferable to some plastic containers. |
| Refrigerator (Optional) | Allows cold brew to steep and store at refrigerator temperature rather than at room temperature. Refrigerator steeping takes longer but may produce a cleaner result and reduce the risk of unwanted flavors developing during extended steeping. |
Standard Cold Brew Recipe
This recipe produces a moderate-strength cold brew suitable for drinking with a small amount of dilution or over ice. It is a reasonable starting point for someone making cold brew for the first time.
Ingredients
100 g coarsely ground coffee, 1000 g (1 liter) cold or room-temperature water.
Equipment
Large jar or pitcher, scale, coarse grinder, fine-mesh strainer or paper filter, storage bottle.
Recommended Starting Recipe
Ratio: 1:10. Grind size: coarse, similar to coarse sea salt. Steep time: 16 hours at room temperature or 20-24 hours in the refrigerator. Serving: dilute lightly with water or ice, or serve as-is over ice.
- Weigh 100 g of coffee beans and grind coarsely.
- Add the ground coffee to the brewing container.
- Weigh out 1000 g of cold or room-temperature water and pour it over the grounds, making sure all of the coffee is saturated.
- Stir briefly to ensure no dry pockets of coffee remain.
- Cover the container and let it steep for 16 hours at room temperature (or 20-24 hours in the refrigerator).
- Strain the mixture through a fine mesh strainer to remove the bulk of the grounds, then filter again through a paper filter or cheesecloth for a clearer result.
- Transfer the brewed coffee to a clean bottle and refrigerate.
- Serve over ice, diluted with water to taste if the result is stronger than preferred.
Cold Brew Concentrate Recipe
Concentrate is a cold brew made at a strong ratio – typically 1:4 to 1:5 – so the result is significantly more intense than what is served. It is too strong to drink without dilution. People make concentrate because it is efficient: a single batch can be diluted in different ways across several days, used for iced coffee one day and a cold brew latte the next, without re-brewing.
Dilution options for concentrate generally fall between 1:1 and 1:3 (concentrate to water or milk), depending on how strong the finished drink should be. Starting at a 1:1 dilution and adjusting from there is a practical approach – add more water or milk gradually until the strength matches preference.
Concentrate stores well because its strength means any flavor changes during storage are proportionally smaller relative to the overall intensity. It should still be kept refrigerated and used within the same general timeframe as regular cold brew.
Ingredient | Amount |
Coarsely ground coffee | 200 g |
Cold or room-temperature water | 800 g (1:4 ratio) |
Steps:
- Weigh and coarsely grind 200 g of coffee.
- Combine the grounds with 800 g of water in a large container, stirring to saturate all the coffee.
- Cover and steep for 18-24 hours at room temperature or in the refrigerator.
- Strain through a mesh strainer, then a paper filter or cheesecloth for a cleaner result.
- Store the concentrate in a sealed bottle in the refrigerator.
- Dilute with water, milk, or a plant-based milk at a 1:1 to 1:3 ratio when serving.
Ready-to-Drink Cold Brew Recipe
A ready-to-drink recipe uses a lighter ratio than a concentrate so the brewed coffee can be served with little or no additional dilution. This recipe is suited to people who want to pour a glass straight from the refrigerator and drink it over ice without measuring out a dilution ratio each time.
A 1:12 ratio with a 16-18 hour steep produces a balanced result – full enough in flavor to stand on its own but not so strong that it requires significant dilution. The flavor characteristics are smoother and milder than concentrate, with less of the sharper edge that very strong ratios can produce.
Ingredient | Amount |
Coarsely ground coffee | 80 g |
Cold or room-temperature water | 960 g (1:12 ratio) |
Storage recommendations: keep refrigerated in a sealed bottle and consume within 7-10 days. Because this recipe is already at drinking strength, it does not need to be diluted further – pour over ice and serve.
Small Batch Cold Brew Recipe
A small-batch recipe is suited to a single person making one to two servings at a time, without committing to a large jar that takes up refrigerator space for a week. Common ratios for small batches range from 1:8 to 1:10, similar to the standard recipe, just scaled down in total volume.
Steeping recommendations stay the same regardless of batch size – 12 to 24 hours depending on preferred strength – since steep time is governed by grind size and ratio, not total volume.
Sample recipe: 25 g coarsely ground coffee, 250 g cold water (1:10 ratio). Combine in a jar or large mug-sized container, steep for 14-16 hours, strain, and serve over ice. This produces roughly one serving with light dilution, or two servings if diluted further.
Large Batch Cold Brew Recipe
Large batch recipes are useful for households or for anyone who wants to brew once and have cold brew available for most of the week. Large batches are most practical when brewed as concentrate, since concentrate takes up less storage space relative to its strength and can be diluted differently for different uses throughout the week.
Storage considerations become more important at larger volumes – a large batch needs a container with enough capacity in the refrigerator, and the full batch should be strained and transferred to storage promptly after steeping to avoid continued extraction.
Ingredient | Amount |
Coarsely ground coffee | 400 g |
Cold or room-temperature water | 1600 g (1:4 ratio, concentrate) |
This produces roughly 1.4-1.5 liters of concentrate after straining, which can be diluted at a ratio of 1:1 to 1:3 to produce 3-6 liters of finished drink. Serving ideas for a large batch include keeping a portion as concentrate for cold brew lattes, diluting another portion to ready-to-drink strength for daily iced coffee, and using a small portion for flavored variations.
Cold Brew Serving Variations
Cold Brew Over Ice
The most straightforward serving method. Pour cold brew (diluted if using concentrate) over a full glass of ice. The ice will dilute the drink further as it melts, so accounting for some additional dilution when choosing the starting strength is worth doing – a slightly stronger pour over a full glass of ice often balances out by the time the ice has partially melted.
Cold Brew with Milk
Adding milk to cold brew softens acidity and adds body and sweetness. Whole milk produces a rounder, creamier result. The ratio of cold brew to milk is a matter of preference – starting around equal parts and adjusting from there is a reasonable approach. Concentrate is often used as the base for milk-based cold brew drinks since the dilution from the milk itself accounts for some of the strength reduction.
Cold Brew with Cream
Cream adds more body and richness than milk, with a smaller volume needed to achieve a noticeable effect. A small amount of cream – a tablespoon or two per serving – changes the texture and mouthfeel of the drink without significantly diluting the coffee flavor, unlike the larger volumes typically used with milk.
Sweetened Cold Brew
Because cold brew is never heated, granulated sugar does not dissolve into it easily – it tends to sink and settle rather than fully dissolve in cold liquid. Simple syrup (equal parts sugar and water, heated until dissolved, then cooled) dissolves into cold brew readily and is the most practical way to sweeten it. Flavored syrups work the same way and are covered in the flavored recipes below.
Flavored Cold Brew
Flavoring can be added during steeping (infusing spices or other ingredients directly with the coffee and water) or after brewing (adding flavored syrups or extracts to the finished cold brew). Adding flavor during steeping infuses it more thoroughly but ties the flavor to that entire batch. Adding flavor after brewing allows the same batch of cold brew to be used for multiple different flavored drinks.
Cold Brew Recipe Comparison
| Recipe Type | Ratio | Steep Time | General Characteristics |
|---|---|---|---|
| Standard Cold Brew | 1:10 | 14-18 hours | Moderate strength. Drinkable with light dilution or served over ice. A practical starting point for most home brewers. |
| Cold Brew Concentrate | 1:4 to 1:5 | 18-24 hours | Very strong and designed for dilution before drinking. Efficient for storage and flexible for different serving styles. |
| Ready-to-Drink | 1:8 to 1:12 | 16-18 hours | Brewed at drinking strength with little or no dilution required. Smooth, balanced, and convenient for daily use. |
| Small Batch | 1:8 to 1:10 | 12-16 hours | Produces one to two servings. A shorter steep time creates a lighter result suited for immediate consumption. |
| Large Batch | 1:4 (as concentrate) | 18-24 hours | Brewed as a concentrate for efficient storage. Dilution can be adjusted depending on intended use throughout the week. |
How Variables Affect Cold Brew Recipes
Coffee Dose
Increasing the coffee dose relative to water (a stronger ratio) increases flavor intensity, body, and the perception of bitterness if the steep time is also long. Decreasing the dose produces a lighter, thinner result that may taste watery if reduced too far without adjusting the steep time.
Grind Size
A coarser grind slows extraction, reducing bitterness and the rate at which flavor compounds enter the water – useful for longer steeps. A finer grind speeds extraction, which can increase strength but also increases bitterness and produces more sediment that is harder to filter out.
Water Quality
Cold brew is roughly 98-99% water, so water quality affects flavor noticeably. Water with strong mineral content or a chlorine taste will carry into the finished brew. Filtered water generally produces a cleaner result, particularly for longer steeps where any off-flavors in the water have more time to combine with the coffee.
Steeping Time
Longer steeping increases extraction, which generally increases body, sweetness, and strength up to a point, after which additional time mainly adds bitterness without proportional gains in flavor. Shorter steeping produces a lighter, brighter result that may taste underdeveloped or acidic if too short for the grind size and ratio used.
Dilution
Dilution reduces strength and flavor intensity across the board – sweetness, bitterness, acidity, and body all decrease proportionally. Because dilution affects the whole flavor profile evenly, it is a useful tool for adjusting overall strength without changing the underlying brew, but it cannot fix an imbalance (like excess bitterness) that exists in the concentrate itself.
Roast Level
Roast level affects the flavor compounds present in the coffee before brewing even begins. Lighter roasts bring more acidity and brighter flavor notes into cold brew, which some people find too sharp without some dilution adjustment. Darker roasts bring more body and bitterness, which cold brew’s smoothing effect (cold extraction reduces perceived acidity generally) can balance well.
Cold Brew Recipes for Different Roast Levels
Light Roasts
Light roasts carry more acidity and brighter, fruit-forward characteristics. Cold brewing softens this acidity compared to hot brewing, but a very light roast can still produce a sharper cold brew than darker roasts. A slightly longer steep (toward 18-20 hours) and a ratio on the stronger end (1:8 to 1:10) can help round out the brightness. Light roast cold brew often benefits from being served with a touch more dilution to avoid a sharp or sour edge.
Medium Roasts
Medium roasts are generally the most forgiving for cold brew. They balance acidity and body without leaning heavily toward either extreme, and standard ratios (1:8 to 1:10) and steep times (14-18 hours) tend to produce reliable results without much adjustment. Medium roasts are a practical choice for anyone making cold brew for the first time.
Dark Roasts
Dark roasts bring more body and bitterness, which can come across as heavy or overly intense in cold brew if the ratio is too strong. A slightly weaker ratio (1:10 to 1:12) and a moderately steep time (12-16 hours) can prevent the bitterness from becoming overwhelming. Dark roast cold brew pairs well with milk-based serving variations, since the added body and bitterness complement dairy or plant-based milks.
Cold Brew Recipe Mistakes
| Issue | Possible Cause | Adjustment |
|---|---|---|
| Weak cold brew | Ratio is too light for the intended use, steep time is too short, or grind size is too coarse for the steep duration. | Increase the coffee dose relative to water, extend the steep time slightly, or use a marginally finer grind while keeping it coarse overall. |
| Bitter cold brew | Steep time is too long, grind size is too fine, or a dark roast is brewed at too strong a ratio. | Reduce steep time, use a coarser grind, or adjust to a lighter ratio with more water relative to coffee. |
| Overly concentrated coffee | Concentrate is served without enough dilution, or a strong concentrate recipe is mistaken for a ready-to-drink recipe. | Dilute concentrate at approximately 1:1 to 1:3 with water or milk before serving. Confirm the recipe type before serving without dilution. |
| Cloudy coffee | Grind is too fine, straining is insufficient, or fine particles pass through a coarse filter. | Use a coarser grind, strain through a mesh strainer first, then filter again with a paper filter or cheesecloth. |
| Watery flavor | Ratio is too light, steep time is too short, or a properly brewed batch has been over-diluted. | Use a stronger coffee-to-water ratio, extend steep time slightly, or reduce dilution when serving. |
| Harsh taste | Poor water quality, very light roast brewed at a strong ratio without enough dilution, or steeping at too warm a temperature. | Use filtered water, dilute light roast cold brew further, or steep in the refrigerator instead of at room temperature. |
Flavored Cold Brew Recipes
Vanilla Cold Brew
Add vanilla syrup (or a small amount of vanilla extract dissolved in simple syrup) to brewed cold brew, starting with about one tablespoon per serving and adjusting to taste. Vanilla works well with both black cold brew and milk-based versions. It softens acidity slightly and adds a rounded sweetness without overpowering the coffee flavor.
Chocolate Cold Brew
Stir a small amount of chocolate syrup or cocoa-based syrup into cold brew, about one to two tablespoons per serving. Chocolate pairs particularly well with darker-roasted cold brew, where the bitterness of the cocoa complements the bitterness already present in the coffee rather than competing with brighter acidity.
Caramel Cold Brew
Caramel syrup added to cold brew, around one tablespoon per serving, adds sweetness with a slightly toasted, buttery note. Caramel cold brew is commonly served with milk, where the caramel flavor integrates into the creaminess of the drink. A small drizzle of caramel on top before stirring can be used for presentation.
Cinnamon Cold Brew
Cinnamon can be added during steeping (a cinnamon stick placed in the brewing container along with the coffee grounds) or after brewing as a cinnamon-infused simple syrup. Steeping with cinnamon directly infuses a more subtle, woody spice note throughout the batch. A syrup-based approach allows the cinnamon flavor to be added only to individual servings as desired.
Citrus Cold Brew
A small amount of citrus zest (orange is most common) added to the cold brew while steeping introduces a bright, aromatic note that complements the brightness already present in lighter roasts. Citrus and coffee are a less common pairing and work best in small amounts – a little zest goes a long way, and too much can overwhelm the coffee flavor entirely.
Cold Brew and Milk-Based Recipes
Cold Brew Latte
A cold brew latte combines cold brew concentrate with milk, typically at a ratio of around 1:2 to 1:3 (concentrate to milk), poured over ice. The higher proportion of milk relative to a standard cold brew serving gives the drink a latte-like character – creamier and milder than black cold brew, with the coffee flavor still present but balanced by the milk.
Cold Brew with Oat Milk
Oat milk has a naturally sweet, slightly creamy character and tends to blend smoothly with cold brew without separating as quickly as some other plant-based milks. A 1:1 to 1:2 ratio of cold brew concentrate to oat milk produces a balanced result. Oat milk’s natural sweetness means added sugar or syrup may be less necessary compared to other milk options.
Cold Brew with Whole Milk
Whole milk adds richness and body to cold brew due to its fat content. A 1:1 ratio of concentrate to whole milk produces a noticeably creamy result. Whole milk integrates smoothly with cold brew and is a common choice for cold brew lattes when a fuller mouthfeel is preferred over a lighter milk option.
Cold Brew with Plant-Based Milks
Different plant-based milks behave differently with cold brew. Almond milk is thinner and can separate more visibly when combined with acidic cold brew, particularly with lighter roasts. Soy milk is closer to dairy in body and tends to blend smoothly. Coconut milk adds a distinct flavor that pairs more selectively with certain flavored cold brew recipes. Testing a small amount before committing to a full serving is a practical way to find a preferred combination.
Storing Cold Brew
Refrigeration
Cold brew should be refrigerated promptly after straining, whether it is concentrate or ready-to-drink. Refrigeration slows the gradual flavor changes that continue to occur in brewed coffee over time, even after the grounds have been removed.
Storage Containers
Glass bottles or jars with airtight lids are well suited to storing cold brew. Glass does not absorb odors from the refrigerator the way some plastics can, and an airtight seal limits oxidation, which is one of the main contributors to flavor changes during storage.
Shelf Life
Ready-to-drink cold brew generally stays good for about 7 to 10 days when refrigerated in a sealed container. Flavor quality is usually best within the first 5 to 7 days, after which the brew remains safe to drink for longer but may taste noticeably flatter or duller.
Concentrate Storage
Cold brew concentrate, due to its strength, often stays usable slightly longer than ready-to-drink brew – commonly up to two weeks when refrigerated in a sealed container – though flavor quality still declines gradually over that period. Concentrate should be diluted only at the time of serving, not stored pre-diluted, since diluted coffee degrades faster than concentrate.
Flavor Changes Over Time
Over several days, cold brew tends to lose some of its brighter or more delicate flavor notes first, leaving a flatter, more one-dimensional profile. Some oxidation can also introduce a slightly stale or cardboard-like note in older batches. These changes happen gradually and do not make the coffee unsafe to drink, but they do affect how closely the result matches the flavor of a freshly strained batch.
Common Cold Brew Terms
| Term | Meaning |
|---|---|
| Cold Brew | Coffee made by steeping coarsely ground coffee in cold or room-temperature water for an extended period, typically 12-24 hours, without applying heat. |
| Concentrate | Cold brew made at a strong ratio, commonly 1:4 to 1:5, intended to be diluted with water, milk, or another liquid before drinking. |

Frequently Asked Questions
There is no single best ratio – it depends on how the cold brew will be used. A 1:8 to 1:10 ratio works well for a brew that can be served with light dilution or over ice. A 1:4 to 1:5 ratio produces a concentrate that needs to be diluted before drinking. Starting around 1:10 and adjusting from there based on taste is a practical approach for most home brewers.
Concentrate is a cold brew made at a strong ratio, typically 1:4 to 1:5, so the result is too intense to drink without dilution. It is brewed this way for storage efficiency and flexibility – the same batch of concentrate can be diluted differently depending on how it is served, whether over ice, with milk, or as a base for flavored drinks.
Most cold brew recipes call for a steep time between 12 and 24 hours. Shorter steeps (12-14 hours) produce a lighter, brighter result, while longer steeps (18-24 hours) produce a fuller, stronger result. Steeping much longer than 24 hours does not generally improve flavor further and can introduce flat or overly bitter notes.
Yes. Because cold brew was never heated during extraction, warming it afterward does not bring out the same harshness that reheating hot-brewed coffee can. Cold brew can be gently warmed and served hot, though some of the smoothness associated with cold brewing may be less noticeable once heated.
Ready-to-drink cold brew generally stays good for about 7 to 10 days when refrigerated in a sealed container, with the best flavor in the first 5 to 7 days. Concentrate, due to its strength, often stays usable for up to two weeks under the same storage conditions, though flavor quality declines gradually over that period in both cases.
A Final Note
A good cold brew recipe is a starting point, not a fixed rule. Adjust ratio, steep time, and dilution to match the coffee and the result you want.
