DIY 7 Brew Cold Brew Recipe – Get the Taste Without the Drive-Thru
Cold brew does not require special equipment. It requires time. Twelve to twenty-four hours of cold steeping, coarse-ground coffee, and a filter are the entire requirement list, which surprises a lot of first-time home cold brew makers who assume they need a dedicated cold brew maker or some other specialized tool before they can start.
This is genuinely one of the most approachable recipes in our copycat collection, and it also serves as the base for two other drinks: the Blondie Cold Brew and Brunette Cold Brew. Master this one recipe and you effectively unlock three finished drinks from a single evening’s preparation.
Quick Answer: Combine one cup of coarse-ground coffee with four cups of cold water, steep in the refrigerator for 18 hours, then strain through a fine mesh filter to produce a concentrate you dilute with water, ice, or half-and-half to match 7 Brew’s official Cold Brew. The whole process takes about five minutes of active work spread across a day of passive steeping.
Recipe Overview
Cold brew is fundamentally a different extraction method than hot coffee or espresso, not just coffee served cold. Steeping coarse-ground coffee in cold water for an extended period produces a smoother, less acidic concentrate than hot extraction methods, which is part of why 7 Brew’s Cold Brew and its variations, like the Blondie Cold Brew and Brunette Cold Brew, have a distinctly different character from their espresso-based breve counterparts.
This recipe makes about four cups of cold brew concentrate, enough for roughly six to eight finished drinks depending on how you dilute it, and it is the base recipe you will use for the flavored variations covered further down.
Unlike our breve recipes, which reward precise technique and fresh preparation for each drink, cold brew is inherently a batch process. You do the work once, and you have a supply that lasts for the better part of two weeks, which changes the entire cost and convenience calculation compared to daily espresso preparation.
Ingredients
- 1 cup coarse-ground coffee (medium to dark roast works best for a bold, 7 Brew-style base)
- 4 cups cold, filtered water
- Half-and-half or milk, to taste, for the finished drink
- Ice
- Optional: simple syrup, caramel sauce, or dark chocolate sauce for a flavored variation
Grind size matters more than most people expect. A fine grind, the kind used for espresso or drip coffee, will over-extract during a long cold steep and produce a muddy, bitter concentrate that is difficult to correct afterward. Coarse grind, similar to what you would use in a French press, is the correct choice here.
Bean choice matters less for cold brew than it does for espresso, since the extended, gentle extraction process tends to smooth out differences between beans more than a fast, high-pressure espresso pull does. That said, a medium to dark roast generally produces a bolder result closer to what most people expect from a 7 Brew-style Cold Brew than a light roast will.
Expert Tip: Use a 1:4 coffee-to-water ratio for a concentrate strong enough to dilute later, not a 1:1 ratio meant to be drunk directly. Many home cold brew failures come from treating the steeping ratio as the final drink ratio rather than as a concentrate you will cut with water, ice, or half-and-half afterward.
Equipment Needed
This is the section where most people are pleasantly surprised. You do not need an espresso machine, a French press, or any dedicated cold brew equipment to make this work.
- Required: A large jar, pitcher, or container with a lid, big enough to hold at least five cups of liquid.
- Required: A fine mesh strainer, cheesecloth, or a coffee filter for straining the grounds out afterward.
- Required: A coffee grinder, or pre-ground coarse coffee if you do not have one. Grinding your own coffee coarse right before steeping produces a fresher result, but pre-ground coarse coffee, often labeled for French press or cold brew use, works fine.
- Optional: A dedicated cold brew maker with a built-in filter, which simplifies straining but is not required for a good result.
If you already own a French press, it doubles nicely as both your steeping container and your straining tool, since the plunger mechanism filters out most of the grounds in one motion. This is a genuinely convenient combination if you happen to have one, though not a requirement.
Step-by-Step Instructions
- Combine the coarse-ground coffee and cold water in your container, and stir gently to make sure all the grounds are saturated.
- Cover and refrigerate for 18 hours. Anywhere from 12 to 24 hours works, with 18 hours landing at a good middle point between under-extracted and overly intense.
- Strain the mixture through a fine mesh strainer lined with cheesecloth, or through a coffee filter, into a clean container. This may take a few passes to get the liquid fully clear of grounds.
- To serve, fill a glass with ice, pour the cold brew concentrate to about half the glass, then top with water or half-and-half to taste.
- Stir and adjust the dilution ratio until it matches your preferred strength.
Total active time across the whole process is about five to ten minutes; the rest is passive steeping time that requires no attention. This makes cold brew one of the most realistic weekday recipes on this site, since the actual work happens the night before you want to drink it.
A useful habit is starting your steep the same evening every week, so your supply naturally refreshes on a predictable schedule rather than running out unexpectedly on a morning you were counting on it. Since the concentrate keeps for up to two weeks, a weekly steeping routine gives you a comfortable buffer even if you occasionally skip a week.
Why Cold Extraction Produces a Different Result
Hot water extracts coffee compounds quickly and aggressively, pulling out oils, acids, and flavor compounds within minutes. Cold water extracts much more slowly and selectively, which is the core reason cold brew tastes smoother and less acidic than hot-brewed coffee cooled down afterward. Iced hot coffee and true cold brew are genuinely different beverages, not the same coffee served at different temperatures.
This is also why steep time matters so much more for cold brew than brew time does for hot coffee. A hot drip brew finishes extracting in a few minutes; cold extraction needs many hours to reach a comparable flavor intensity, which is the entire reason this recipe calls for patience rather than any particular piece of equipment.
Building the Blondie and Brunette Cold Brew Variations
Once you have your base concentrate, the flavored 7 Brew Cold Brew variations are a short step further. For a home version of the Blondie Cold Brew, add one tablespoon of caramel sauce and half a tablespoon of vanilla syrup to your glass before pouring in the concentrate and half-and-half, the same caramel-and-vanilla approach used in our Blondie copycat recipe.
For a home version of the Brunette Cold Brew, add one tablespoon of dark chocolate sauce instead, following the same restrained, no-added-sweetener approach used in the Brunette recipe. In both cases, the cold brew concentrate replaces the espresso shots from those recipes, and half-and-half plays the same role it does in the breve versions.
| Version | Add to Cold Brew Base | Flavor Profile |
|---|---|---|
| Plain Cold Brew | Water or half-and-half only | Smooth, low acid, straightforward coffee |
| Blondie Cold Brew | Caramel sauce, vanilla syrup, half-and-half | Sweet, caramel-vanilla forward |
| Brunette Cold Brew | Dark chocolate sauce, half-and-half | Chocolate-forward, more coffee-forward |
How Close Is This to the Original?
Flavor: very close, actually closer than our breve recipes get to the original, since cold brew extraction is a more forgiving, less technique-dependent process than pulling espresso. Texture: close, with the main variable being how finely you strain the concentrate; a coffee filter produces a cleaner result than a basic mesh strainer. Overall experience: this is one of the easier home recreations on this site to get genuinely right on the first attempt.
Where a small gap remains is coffee bean sourcing. 7 Brew uses its own specific coffee blend, which this recipe cannot replicate exactly, so your home version’s flavor profile will depend heavily on which beans you choose. A medium to dark roast gets you into the right general territory.
This is also one of the few recipes where a slightly imperfect execution still produces a genuinely drinkable result. Even if your steep time or straining is not perfectly dialed in on the first attempt, the worst likely outcome is a slightly weaker or slightly more bitter cup rather than something unrecognizable, which makes this a forgiving recipe to learn on.
Customization Ideas and Dietary Adaptations
- Dairy-free: substitute barista-formulation oat milk for half-and-half. The result is thinner and slightly sweeter but genuinely workable.
- Sugar-free: use sugar-free caramel or chocolate sauce for the flavored variations, or skip flavoring entirely for the plain version, which has no added sugar by default.
- Stronger concentrate: increase to a 1:3 coffee-to-water ratio for a more intense base, useful if you plan to dilute heavily with ice or milk.
- Decaf: use decaf coarse-ground coffee. The steeping process and timing remain identical.
- Nitro-style texture: pour the finished drink vigorously from a height into your glass, or use a milk frother briefly at the surface, to introduce a bit of foam similar to nitro cold brew, though a true nitro effect requires pressurized equipment this recipe does not use.
Nutrition Estimate
A plain cold brew with a splash of half-and-half and no added sweetener is remarkably low in calories, and we estimate it at approximately 20 to 40 calories per 16-ounce serving, depending on how much half-and-half you add. Adding caramel sauce or chocolate sauce for the flavored variations raises this closer to the 190 to 260 calorie range we estimated for the Blondie and Brunette recipes.
- Plain, with a splash of half-and-half: approximately 20-40 calories
- Caffeine: variable based on steep time and coffee-to-water ratio, generally in a similar range to a strong cup of drip coffee per serving
- Sugar: 0 grams for the plain version; 14-26 grams for flavored variations, depending on the sauce used
These figures are our own estimate based on standard commercial ingredient labels and typical cold brew extraction ranges, not sourced from 7 Brew’s own nutrition data.
Cost Per Serving
Based on current grocery pricing for coarse-ground coffee, we estimate this recipe costs roughly 40 to 60 cents per finished serving for the plain version, making it one of the most cost-effective recipes in our copycat collection. The flavored variations add the same 60 to 80 cents per serving in caramel or chocolate sauce that our Blondie and Brunette recipes calculate.
Since one batch produces six to eight servings from a single steeping session, this recipe scales particularly well for anyone drinking cold brew daily. Use the 7 Brew Calorie and Price Calculator to compare your specific savings against current drive-thru pricing.
For a daily cold brew drinker who normally makes five drive-thru visits a week, switching to a home batch routine can realistically save the largest dollar amount of any recipe in our collection, simply because the per-serving cost here is lower than any of our espresso-based recipes and the batch size means fewer preparation sessions overall.
Storage Tips
This is the recipe on our site with the best storage life, since cold brew concentrate holds up significantly longer than espresso or brewed hot coffee.
- Strained cold brew concentrate: store in a sealed container in the refrigerator for up to two weeks. Flavor gradually mellows over time but does not spoil within that window.
- Do not leave the coffee grounds steeping longer than 24 hours, even in the refrigerator, since extended contact time can push the flavor toward bitter and over-extracted.
- Do not freeze the concentrate; freezing does not meaningfully extend shelf life for coffee concentrate and is unnecessary given how well it already keeps refrigerated.
Common Mistakes to Avoid:
- Using a fine grind instead of coarse. Fine grounds over-extract during a long cold steep and produce a bitter, muddy result.
- Treating the steeping ratio as the final drink ratio. This recipe produces a concentrate meant to be diluted, not a drink meant to be consumed straight from the steeping container.
- Steeping for too long, past 24 hours. Extended contact time pushes flavor toward bitter rather than continuing to improve it.
- Skipping the straining step or straining incompletely, which leaves gritty sediment in the finished drink.
- Assuming special equipment is required before starting. This recipe genuinely only needs a container, a strainer, and time.
Frequently Asked Questions
Do I need special equipment to make cold brew at home?
No. A container with a lid, a fine mesh strainer or coffee filter, and coarse-ground coffee are all you need. A dedicated cold brew maker simplifies the straining step but is not required for a genuinely good result.
How long should I steep cold brew?
Between 12 and 24 hours, with 18 hours landing at a good middle point. Shorter steeps produce a lighter, less intense concentrate; longer steeps risk over-extraction and bitterness.
Can I use regular ground coffee instead of coarse grind?
You can, but the result will likely be more bitter and muddy than intended, since finer grounds over-extract during a long cold steep. Coarse grind, similar to French press grind, is the correct choice for cold brew specifically.
How do I make a Blondie or Brunette Cold Brew at home?
Use this cold brew concentrate as your coffee base, then add caramel sauce and vanilla syrup for a Blondie-style version, or dark chocolate sauce for a Brunette-style version, following the same flavor approach as our individual Blondie and Brunette copycat recipes.
How long does cold brew concentrate last in the fridge?
Up to two weeks once strained and refrigerated, making it one of the most storage-friendly recipes in our copycat collection. Flavor gradually mellows over time but does not spoil within that window.
Is this an official 7 Brew recipe?
No. This is our tested approximation of the drink described on the official Cold Brew page, developed independently. sevenbrewmenucoffee.com is not affiliated with 7 Brew Coffee Inc., and this recipe is not licensed or endorsed by the company.
Can I make cold brew in smaller or larger batches?
Yes, the 1:4 coffee-to-water ratio scales linearly in either direction. Half the recipe for a smaller batch, or double it if you have a large enough container and want a bigger supply for the week.
Why is my cold brew weaker than 7 Brew’s version?
This is usually a dilution issue rather than an extraction issue. Try using less water or ice when serving, or increase your steeping ratio to 1:3 coffee-to-water for a stronger concentrate that can handle more dilution at serving time.

Final Notes
Cold brew is the most beginner-friendly recipe in our copycat collection precisely because it does not depend on precise technique the way espresso-based drinks do. Get the grind size right, respect the steeping time, and dilute the concentrate to your preference, and you have a genuinely satisfying, low-cost home version that holds up for two weeks in the refrigerator.
Once you have a batch on hand, it becomes the base for the Blondie and Brunette Cold Brew variations, giving you three different finished drinks from a single steeping session. This is one of the more efficient recipes on this site for anyone trying to replace multiple weekly drive-thru visits with home preparation.
If you are new to home coffee preparation generally, this is genuinely the recipe to start with before attempting the espresso-based Blondie or Brunette recipes. The lower equipment barrier and more forgiving technique make it a low-risk way to build confidence before moving on to recipes that depend more heavily on precise execution.
