Introduction
Cold brew coffee has become a staple for anyone who wants a smooth, less acidic cup without the bitterness that sometimes comes from hot brewing. Unlike iced coffee, which is simply hot coffee poured over ice, cold brew is made by steeping coarse coffee grounds in cool or room-temperature water for an extended period. The result is a concentrate that can be diluted with water, milk, or ice and enjoyed straight from the refrigerator.
One of the most common questions beginners ask is what to use to make cold brew coffee? The answer depends on your budget, how much counter space you have, and whether you want a dedicated appliance or are happy to improvise with kitchen tools you already own. You do not need an expensive machine to make excellent cold brew, but the right gear can make the process cleaner, more consistent, and easier to repeat.
This guide walks through the equipment you actually need, from basic jars and filters to dedicated cold brew makers. It also covers grind size, water ratios, step-by-step methods, and common mistakes to avoid. By the end, you will know exactly what to use to make cold brew coffee at home, whether you are starting with almost nothing or looking to upgrade your setup.

What to Use to Make Cold Brew Coffee? Understanding the Basics
Before choosing equipment, it helps to understand how cold brew works. Ground coffee sits in water for twelve to twenty-four hours, extracting flavor slowly without heat. Because there is no hot water to force extraction, the grind must be coarse, and the contact time must be long. The gear you choose mainly affects two things: how easily you can separate the grounds from the liquid, and how convenient it is to store the finished brew.
Most cold brew setups fall into one of two categories. Immersion methods steep the grounds directly in water, then filter them out. Slow-drip methods let water pass through a bed of coffee one drop at a time. Both produce a smooth concentrate, but immersion gear is usually cheaper and simpler for home use. Slow-drip towers tend to cost more and take up more space, though they can finish a batch faster.
When people ask what to use to make cold brew coffee, they are usually looking for a container, a filter, and a way to grind beans. You can buy a single device that handles all three, or you can assemble the same functions from separate kitchen items. Neither approach is wrong, and the best choice is the one you will actually use on a regular basis.
It is also useful to decide whether you want a concentrate or a ready-to-drink batch. A concentrate is stronger and takes up less fridge space, but you must dilute it before serving. A ready-to-drink batch uses more coffee and water upfront but can be poured straight from the container. Your gear choice does not change this decision, but it does affect how easy it is to store and pour the final product.
Essential Cold Brew Gear Overview
Every cold brew setup needs a few core components. You need something to hold the coffee and water while it steeps, something to separate the grounds from the liquid, a grinder if you are starting with whole beans, and a storage vessel for the finished concentrate. The quality of each piece affects flavor, clarity, and cleanup.
Brew Containers
The brew container is where the coffee and water meet. Glass is a popular choice because it does not absorb odors and lets you see the steeping process. Food-grade plastic is lightweight and less likely to break, though it can retain smells over time. Stainless steel is durable and opaque, which protects the coffee from light, but you cannot see inside without opening the lid. Whatever material you choose, make sure it is non-reactive and large enough for your batch size.
Container shape matters too. A wide mouth makes it easier to add grounds and stir the mixture, while a narrow neck can limit oxygen exposure but makes cleaning more difficult. If you plan to store the container in a refrigerator door, check the dimensions before you buy so it fits without tipping over.
Filtration Options
Filtration is what separates pleasant cold brew from a gritty cup. Paper filters produce the clearest result but can absorb some of the coffee’s natural oils. Metal mesh filters let more oil through, creating a fuller body with a little sediment. Cloth filters, such as cheesecloth or reusable nut milk bags, sit somewhere in between. Many dedicated cold brew makers include a built-in filter, which removes the need for separate supplies.
If you use a paper filter, expect a slower pour because fine particles can clog the pores. Metal filters are reusable and environmentally friendly, but they require thorough cleaning to prevent old coffee oils from turning rancid. Cloth filters are inexpensive and easy to replace, though they may need a rinse between batches to avoid carrying over flavors.
Coffee Grinders
Cold brew requires a coarse grind, similar to sea salt or coarse sand. A burr grinder gives you consistent particle size, which leads to even extraction and less bitterness. Blade grinders are cheaper but chop unevenly, producing a mix of fine powder and large chunks that can over-extract in spots. If you do not own a grinder, many coffee shops will grind beans coarsely for you, or you can buy pre-ground cold brew coffee, though freshness suffers.
Manual burr grinders are a good middle ground for home brewers. They are affordable, portable, and quiet, though they require some effort for larger batches. Electric burr grinders are faster and more convenient, especially if you make cold brew weekly. Whichever type you choose, look for a model with a clearly marked coarse setting so you do not have to guess.
Storage Containers
Once strained, cold brew concentrate keeps best in an airtight container in the refrigerator. Glass jars with swing-top lids or simple mason jars work well. Avoid leaving brew in the same container you used for steeping if the grounds are still present, because extraction continues and the coffee can become over-strong. A dedicated storage bottle also makes it easier to pour servings without disturbing sediment.
Cold brew concentrate generally stays fresh for seven to ten days when refrigerated. After that, the flavor may dull or develop off-notes. If you make large batches, consider dividing the concentrate into smaller bottles so you open only what you need, limiting air exposure for the rest.
Dedicated Cold Brew Makers
If you make cold brew regularly, a dedicated maker can simplify the process. These devices combine a brewing vessel, a filter, and sometimes a storage carafe in one unit. They range from simple immersion pitchers to tall slow-drip towers.
Immersion Brewers
Immersion cold brew makers are the most common dedicated option. You add coffee and water to a container, let it steep, then remove a filter basket or press a plunger to separate the grounds. Some models have a removable mesh filter that lifts out like a tea infuser. Others use a valve that releases the brewed coffee into a carafe when you set the brewer on top of it. These devices are affordable, easy to clean, and take up little fridge space.
Most immersion makers are designed to sit on a countertop during steeping and then fit inside a refrigerator door for storage. Look for models with measurement markings on the side so you can repeat your recipe without using a separate measuring cup. A non-slip base is also helpful when you are pressing or pouring.

Slow Drip Towers
Slow drip towers, sometimes called Kyoto-style brewers, use gravity to drip water through coffee grounds over several hours. Water sits in an upper chamber and flows through a valve onto a bed of coffee, then drips into a lower carafe. The process can produce a bright, tea-like cold brew in less time than immersion, often three to eight hours depending on the drip rate.
The downside is that towers are tall, fragile, more expensive, and require more attention during setup. You must adjust the valve to control the flow, and you need enough vertical clearance to accommodate the tower. These devices appeal to enthusiasts who enjoy the ritual and want a different flavor profile, but they are not necessary for everyday cold brew.
French Press as Cold Brew Gear
A French press is not marketed as cold brew gear, but it works surprisingly well. You add coarse grounds and cold water to the carafe, stir, and place the lid with the plunger pulled up. After steeping in the fridge or on the counter, you press the plunger down to separate the grounds. The metal filter lets some fine sediment through, which some drinkers enjoy. If you already own a French press, it is one of the easiest ways to start without buying anything new.
Because a French press filter is not as fine as paper, you may want to pour the pressed coffee through a paper filter afterward if you prefer a completely clear cup. Cleaning is straightforward: discard the grounds, rinse the carafe, and wash the plunger assembly.
What to Use to Make Cold Brew Coffee at Home Without Special Equipment
You do not need to buy a single piece of specialized equipment to make excellent cold brew. Many households already have everything required: a container, a way to strain, and a place to store the finished coffee. The tradeoff is that you may need to filter the coffee more than once to achieve a smooth texture.
Mason Jars
A mason jar is perhaps the most accessible cold brew vessel. It is made of glass, has a wide mouth for easy pouring, and seals tightly for steeping and storage. A quart-sized jar is enough for a small batch, while a half-gallon jar works for larger quantities. The main limitation is that you still need a separate method to strain the coffee, such as pouring through a sieve lined with a filter.
Wide-mouth jars are easier to clean than regular-mouth jars, especially when you need to scoop out wet grounds. If you use a jar with a metal lid, avoid letting the coffee touch the lid for long periods, as acidic coffee can react with some metals over time.
Pitchers and Carafes
A large pitcher or carafe can hold several servings of cold brew and usually fits easily in a refrigerator door. Look for one with a lid to keep out fridge odors. Pitchers are convenient for mixing and steeping, but like jars, they do not include a built-in filter. You will need to strain the coffee into a second container before serving.
A pitcher with a spout makes pouring easier and reduces spills. Glass pitchers are ideal because they do not retain odors, but plastic pitchers are lighter and less likely to break if knocked over. Choose a size that matches your typical batch so you are not wasting fridge space on a half-empty container.
Cheesecloth and Fine Mesh Sieves
When you lack a dedicated filter, cheesecloth and a fine mesh sieve can do the job. Place the sieve over a clean jar or pitcher, line it with a double layer of cheesecloth, and pour the steeped mixture through. The cloth catches most grounds, though you may want to run the coffee through a paper coffee filter afterward for a completely clear cup. This method is inexpensive but slower than using a maker with a built-in filter.
A reusable nut milk bag is another alternative to cheesecloth. It is made of fine mesh, holds up well to repeated use, and can be rinsed and dried between batches. If you use a sieve alone without cloth, expect some fine sediment in the final cup, which is harmless but may affect the mouthfeel.
Step-by-Step: Making Cold Brew with Basic Gear
This method uses a jar or pitcher, coarse ground coffee, water, and a simple filter. It works well for beginners who want to test the process before investing in dedicated equipment.
- Measure your coffee and water. A common starting ratio is one cup of coarsely ground coffee to four cups of cold or room-temperature water. Adjust to taste after your first batch.
- Combine the coffee and water in your jar or pitcher. Stir gently to make sure all the grounds are saturated. Dry pockets of coffee will not extract properly.
- Cover the container and let it steep. Leave it at room temperature or in the refrigerator for twelve to eighteen hours. Longer steeping creates a stronger concentrate, but beyond twenty-four hours can introduce bitterness.
- Set up your filter. Place a fine mesh sieve over a clean container and line it with cheesecloth or a paper coffee filter. Pour the mixture through slowly. If you used a French press, simply press the plunger down and pour.
- Store the finished concentrate. Transfer the strained coffee to an airtight bottle or jar and refrigerate. Dilute with equal parts water or milk before serving over ice.
If the brew tastes too strong, add more water or milk. If it tastes weak, use more coffee or extend the steeping time slightly on your next batch. Keeping a simple notebook of ratios and times helps you repeat your favorite results.
Step-by-Step: Using a Dedicated Cold Brew Maker
Dedicated makers vary by design, but most immersion models follow a similar workflow. Always check your device’s manual for specific fill lines and steeping times.
- Add coarse coffee grounds to the filter basket or brewing chamber. Do not pack the grounds down; water needs to flow around them freely.
- Pour cold or room-temperature water over the grounds until you reach the maker’s maximum fill line. Stir if the instructions recommend it.
- Place the lid on the brewer and let it steep. Many immersion makers suggest twelve to twenty-four hours in the refrigerator. Slow-drip towers may finish in three to eight hours depending on the drip rate.
- Separate the grounds. Lift out the filter basket, open the release valve, or press the plunger according to your model’s design. Discard or compost the used grounds.
- Transfer the concentrate to a storage carafe if your maker does not include one. Keep it refrigerated and serve diluted to taste.
Some immersion makers include a paper filter insert that fits inside the mesh basket. Using both can produce a cleaner cup, though it slows the drainage process. If your maker has a reusable mesh filter, scrub it gently with a brush after each batch to remove trapped particles.

Coffee Beans and Grind Size
Any coffee bean can be used for cold brew, but medium to dark roasts often highlight chocolatey and nutty notes that pair well with the smooth, low-acid profile. Light roasts can work too, though they may taste more tea-like and require careful steeping to avoid sourness. Freshness matters, so buy whole beans and grind them shortly before brewing whenever possible.
Grind size is just as important as bean choice. Cold brew needs a coarse, even grind. If the particles are too fine, they can pass through filters and create sludge. Overly fine grounds also extract too quickly, leading to bitterness even without heat. If the grind is too coarse, the coffee may taste weak or under-extracted. Aim for a texture similar to coarse sea salt.
Single-origin coffees can produce distinctive cold brew flavors, such as fruit or floral notes, while blends often offer a balanced, consistent cup. There is no wrong choice, but if you are new to cold brew, start with a medium roast blend before experimenting with more adventurous beans. (See Also:What Water To Use For Coffee Machine)
Water Quality and Ratio
Because cold brew is mostly water, the quality of your water affects the final cup. Filtered water is usually best, especially if your tap water has a strong chlorine or mineral taste. Distilled water is not recommended because it lacks the minerals that help carry coffee flavor.
Ratio is a matter of preference. A standard starting point is one part coffee to four parts water by weight or volume, which produces a concentrate. You can dilute this with water, milk, or ice when serving. If you prefer ready-to-drink cold brew, use a ratio of one part coffee to eight parts water. Experimenting with ratio is one of the easiest ways to customize your brew without buying new gear.
Water temperature also matters less than it does for hot coffee, but it is not irrelevant. Room-temperature water extracts slightly faster than refrigerator-cold water. If you steep in the fridge, you may need a few extra hours to reach the same strength. Consistency is more important than the exact temperature, so choose one method and stick with it while you dial in your recipe.
Tips and Best Practices
Small habits can make a big difference in cold brew quality. Keep these practices in mind regardless of what gear you use.
- Always use coarse grounds to reduce sediment and bitterness.
- Stir the coffee and water at the start so no dry grounds remain.
- Steep in the refrigerator if you prefer a milder brew, or at room temperature for a stronger concentrate.
- Strain the coffee twice if you want a very clear cup, especially when using DIY gear.
- Store concentrate in an airtight container and use it within seven to ten days for the best flavor.
- Label your container with the date you brewed it so you know when it is past its prime.
- Clean your gear thoroughly after every batch to prevent stale oils from affecting the next round.
- Use a kitchen scale for measuring coffee and water if you want repeatable results.
- Try diluting with different liquids, such as oat milk or sparkling water, to find your favorite serving style.
Common Mistakes and How to Fix Them
Even experienced coffee drinkers run into issues with cold brew. Here are the most frequent problems and practical solutions.
Using fine grind: Fine grounds create a muddy, over-extracted brew and are difficult to filter. Switch to a coarse setting and check your grinder before each batch.
Steeping too long: Leaving coffee in water for more than twenty-four hours can produce harsh, woody flavors. Set a timer and taste your brew at the eighteen-hour mark to find your sweet spot.
Skipping the second filter: A single pass through a sieve often leaves fine sediment. Pour the coffee through a paper filter or fresh cheesecloth for a cleaner result.
Storing with the grounds: If you leave steeped coffee sitting on the grounds, extraction continues and the concentrate becomes overly strong. Always separate the grounds promptly after steeping.
Using hot water: Cold brew relies on time, not temperature. Hot water changes the chemistry and produces a different, more acidic drink. Stick to cold or room-temperature water.
Forgetting to dilute: Cold brew concentrate is much stronger than regular coffee. Drinking it straight can be overwhelming and may mask the subtle flavors you worked to extract. Always taste it diluted first.
Reusing grounds: Unlike some tea infusions, cold brew grounds do not produce a good second batch. The soluble flavors are mostly exhausted after the first steep, so use fresh grounds every time. (See Also:What Type Of Ground Coffee For French Press)
Frequently Asked Questions
Can I make cold brew without any special equipment?
Yes. A jar or pitcher, coarse coffee, water, and a strainer lined with cheesecloth or a paper filter are enough. You do not need a dedicated machine to answer the question of what to use to make cold brew coffee at home.
What is the best grind size for cold brew gear?
A coarse, even grind works best. It resembles coarse sea salt and allows slow extraction without clogging filters or creating excess sediment.
How long should cold brew steep?
Twelve to eighteen hours is a good range for most immersion methods. Some people steep for up to twenty-four hours, but longer periods can make the coffee taste bitter or over-extracted.
Do I need a paper filter for cold brew?
Not necessarily. Metal mesh and cloth filters work well, though they may allow more sediment through. A paper filter gives the clearest cup, especially when used as a second pass after straining.
Can I use a French press for cold brew?
Yes. Add coarse grounds and cold water, steep in the refrigerator, then press the plunger to separate the grounds. It is one of the simplest ways to use gear you may already own.
How do I clean cold brew gear?
Rinse out used grounds immediately, then wash containers and filters with warm, soapy water. For metal mesh filters, soak them occasionally to remove coffee oils that soap alone might not cut through.
How long does cold brew concentrate last in the fridge?
When stored in an airtight container, cold brew concentrate typically stays fresh for seven to ten days. After that, the flavor may fade or develop stale notes, so it is best to make smaller batches if you do not drink it regularly.
Conclusion
Making great cold brew does not require an expensive setup. Whether you choose a mason jar, a French press, a dedicated immersion maker, or a slow-drip tower, the most important factors are coarse grounds, clean water, and enough steeping time. If you have been wondering what to use to make cold brew coffee, start with the tools you already have and upgrade only if you find yourself brewing regularly.
Remember to strain thoroughly, store your concentrate in an airtight container, and dilute it to taste before serving. With the right gear and a little patience, you can enjoy smooth, refreshing cold brew at home any time.
