How to Make Cold Brew With Ground Coffee
Phase & LeafShare
Quick answer
Use 60 grams of ground coffee and 480 grams of cool filtered water for a practical 1:8 starting ratio. Combine them in a clean jar, stir until every ground is wet, cover, and refrigerate for 12 hours. Filter through a fine-mesh strainer, then pass the coffee through a rinsed paper filter for a cleaner cup. Serve over ice and dilute with water or milk to taste.
Cold Brew Revival is ground coffee. The live Phase & Leaf bag and Shopify product both identify it that way. It is not the separate coarse-grind supplier option.
This is a researched Phase & Leaf starting method, not a recipe printed on the bag. The current product listing identifies the coffee as ground and intended for cold brew. OXO documents that medium to coarse, including automatic-drip ground, can work in cold-brew equipment. Toddy's experiment guide includes filter grind, a 1:8 ratio, and a 12-hour dwell time among its controlled starting variables.

What you need
- 60 grams Cold Brew Revival ground coffee
- 480 grams cool filtered water
- a clean jar or French press that holds at least 24 fluid ounces
- a digital kitchen scale
- a spoon
- a lid or cover
- a fine-mesh strainer
- a rinsed paper coffee filter and filter holder
- a clean storage container
- ice, water, or milk for serving
Using weight makes the method easier to repeat. Coffee volume changes with grind and how tightly it is packed, so cups and scoops are less dependable.
Why this guide uses ground coffee, not coarse coffee
Cold Brew Revival is the live Standard / 12oz variant. Its product type is Ground Coffee, and the front label says GROUND COFFEE.
The current Phase & Leaf offer is the Standard / 12oz ground variant. A separate coarse option is not sold on this page, so this guide does not relabel the shipped grind as coarse.
The method still works with ground coffee. OXO's cold-brew instructions say medium to coarse grounds work in its brewer and specifically point to the automatic-drip setting as an option. Toddy's experiment guide also includes filter grind as a grind-size test. Finer particles can make filtration slower, which is why this guide uses a second paper-filter pass.
The 1:8 starting ratio
A coffee-to-water ratio tells you how many grams of water are used for each gram of coffee.
At 1:8, every 1 gram of coffee gets 8 grams of water.
| Batch | Ground coffee | Filtered water | Starting use |
|---|---|---|---|
| Small | 30 g | 240 g | One or two drinks |
| Standard | 60 g | 480 g | Two or three drinks |
| Large | 85 g | 680 g | A larger home batch |
Toddy's experiment guide uses 1:5, 1:8, and 1:14 as comparison points rather than declaring one universal answer. This guide chooses 1:8 because it is easy to calculate and leaves room to dilute over ice or with milk.
Treat the first batch as a baseline. If it tastes too strong after filtering, add water or milk in the glass. If it tastes too light, use less serving dilution next time before changing the brew ratio.
Jar method
1. Weigh the coffee and water
Place the empty jar on the scale and tare it. Add 60 grams of Cold Brew Revival ground coffee. Tare again, then add 480 grams of cool filtered water.
2. Wet every ground
Stir gently until no dry pockets remain. Standard ground coffee can form small clumps, so check the bottom and sides of the jar.
Do not whip air into the mixture. The goal is even contact, not foam.
3. Cover and refrigerate for 12 hours
Cover the jar and place it in the refrigerator for 12 hours.
Cold-brew sources commonly use a range rather than one exact time. OXO documents 12 to 24 hours for room-temperature steeping and longer refrigeration in its compact brewer. Toddy uses 8, 12, and 16 hours as controlled dwell-time comparisons and also documents refrigerated brewing. Twelve refrigerated hours is the starting point here because it is simple to schedule and avoids pretending that every coffee needs the same long extraction.
4. Filter twice
Pour the mixture through a fine-mesh strainer to remove most of the grounds. Then pour it through a rinsed paper coffee filter into a clean container.
Let gravity do the work. Standard ground coffee can drain slowly. Do not squeeze the paper filter, because pressure can push fine sediment into the finished drink or tear the filter.
If the paper filter stalls, use a fresh rinsed filter and transfer the remaining liquid carefully.
5. Taste and serve
Pour a small amount over ice and taste it before diluting.
Add cold water or milk a little at a time until the cup fits your preference. Write down what you added. That note turns the first batch into a repeatable method.
Keep the filtered cold brew refrigerated in a clean, sealed container. Make only what you expect to use promptly, and discard it if the aroma, appearance, or storage history seems off.
French press method
A French press can act as the brewing vessel and first filter.
- Add 60 grams of ground coffee to the clean press.
- Add 480 grams of cool filtered water.
- Stir gently until every ground is wet.
- Place the lid on without pressing the plunger down.
- Refrigerate for 12 hours.
- Press very slowly and stop if the resistance becomes excessive.
- Pour the coffee through a rinsed paper filter into a clean container.
Standard ground coffee contains smaller particles than a typical French press grind. Those particles can increase resistance and sediment. Never force the plunger. If it does not move smoothly, pour the mixture through a strainer instead, then complete the paper-filter pass.
The French press is convenient, but the jar method is equally valid. The better choice is the vessel you can clean thoroughly and use consistently.
Cold brew vs iced coffee
Cold brew and iced coffee are not the same process.
Cold brew uses cool water and a long contact time before filtration. Iced coffee is usually brewed hot and then chilled or poured over ice.
Both can produce a cold drink, but the preparation and flavor are different. Cold Brew Revival is positioned for the slow cold-brew routine.

How to adjust the next batch
Change one variable at a time.
| If the cup tastes... | First adjustment to try |
|---|---|
| Too strong | Add more water or milk in the serving glass |
| Too light | Use less serving dilution |
| Too silty | Use a fresh paper filter and let it drain without squeezing |
| Rough or dry | Shorten the next refrigerator time slightly |
| Flat | Lengthen the next refrigerator time slightly |
Keep the coffee, water, vessel, and filtration method the same while testing time. Keep the time the same while testing the serving dilution. This is the most useful lesson in Toddy's experiment guide: isolate one variable so you know what changed the cup.
What this guide does not claim
This recipe does not state a finished-drink caffeine amount. No assay is available for Cold Brew Revival prepared with this method.
It also does not claim a medical benefit, a guaranteed acidity result, or a universal best ratio. Coffee, grind distribution, water, time, filtration, dilution, and serving size all influence the drink.
The useful promise is practical: a weighed starting method for the ground coffee Phase & Leaf actually sells.
FAQ
Is Cold Brew Revival ground coffee?
Yes. The live product is the Standard ground variant, the Shopify product type is Ground Coffee, and the front label says Ground Coffee.
Do I need coarse coffee for cold brew?
No. Medium or automatic-drip ground coffee can work, although it may filter more slowly than coarse coffee. This guide uses a paper-filter finish to manage fine sediment.
How long should I refrigerate cold brew?
Use 12 hours as the first Phase & Leaf test point. Cold-brew guidance commonly spans a range. Record the result, then change only the time if the next batch needs adjustment.
Can I make this in a French press?
Yes. Use the press as the vessel and first filter, press slowly, and stop if resistance is high. Finish through a paper filter because Standard ground coffee can leave more fine sediment.
Is 1:8 the only cold brew ratio?
No. It is a practical starting ratio. Toddy's experiment material demonstrates several ratios, and the right serving strength depends on the coffee, filtration, ice, milk, and personal taste.
How much caffeine is in this cold brew?
Phase & Leaf does not publish an exact amount because Cold Brew Revival has no finished-product assay tied to this recipe and serving. Treat it as caffeinated coffee and consider your full daily intake.
