Making Cold Brew With Regular Ground Coffee

Quick answer

• Yes, you can make cold brew with regular ground coffee, but it may not yield the best results.
• Coarser grinds are generally preferred for cold brew for easier straining and a cleaner taste.
• If using regular (medium) grounds, expect a potentially murkier brew and more sediment.
• You can mitigate some issues by using a good filter or double-filtering your cold brew.
• Adjusting brew time and coffee-to-water ratio can help compensate for the finer grind.
• The flavor profile might be less nuanced compared to cold brew made with coarse grounds.

Who this is for

• Home coffee drinkers who want to try making cold brew but only have regular ground coffee on hand.
• Budget-conscious brewers looking to avoid buying a special grind.
• Experimenters curious about how different grind sizes affect their cold brew.

What to check first

Brewer type and filter type

Before you start, consider what you’re using to brew and filter. If you’re using a French press, the built-in filter might struggle with finer grounds, leading to sediment. Paper filters, like those used in pour-over or drip machines, can be effective but may clog more easily with regular grounds. Some cold brew makers come with fine mesh filters, which are ideal for catching smaller particles. If you’re improvising, you might need to use multiple filters or a fine-mesh sieve.

If you’re using a French press, the built-in filter might struggle with finer grounds, leading to sediment. You might need to pour the French press brew through a paper filter afterward for a cleaner result.

Water quality and temperature

Cold brew relies on time rather than heat to extract flavor, making water quality crucial. Use filtered water for the cleanest taste; tap water can introduce off-flavors. For cold brew, the “cold” in the name is key. The brewing temperature should be at room temperature or slightly cooler, never hot. Using hot water will result in a hot coffee, not cold brew, and can lead to over-extraction and bitterness, especially with finer grounds.

Grind size and coffee freshness

While this guide focuses on using regular ground coffee, it’s important to acknowledge the ideal. Coarse grounds are best for cold brew because they release flavor more slowly and are easier to filter out. Regular grounds are typically medium, meaning they have more surface area. This can lead to faster extraction, potentially bitterness, and more sediment. Fresher coffee is always better, regardless of grind size. Aim for coffee roasted within the last few weeks for optimal flavor.

Coffee-to-water ratio

The ratio of coffee to water significantly impacts the strength and flavor of your cold brew. A common starting point for cold brew is a 1:4 to 1:8 ratio by weight, with 1:4 being very concentrated (a concentrate) and 1:8 being closer to ready-to-drink. Using regular grounds might require slight adjustments. If you find your brew too bitter or muddy, you might need to slightly increase the water or decrease the coffee. For example, if you usually use 1:5 with coarse grounds, you might try 1:6 with regular grounds to start.

Cleanliness/descale status

A clean brewing setup is paramount for good coffee. Any residual oils or old coffee grounds can impart stale or bitter flavors into your fresh brew. Ensure your brewing vessel, filters, and any storage containers are thoroughly washed and dried. If you use a machine for heating water or a French press, check its descaling status. Mineral buildup can affect water flow and taste. Regular cleaning prevents these issues and ensures your cold brew tastes as intended.

Step-by-step (brew workflow)

1. Gather your supplies: You’ll need your regular ground coffee, filtered water, a brewing vessel (like a pitcher or jar), a filter (paper, cloth, or fine-mesh sieve), and a container for the finished brew.

• What “good” looks like: Having everything clean and ready to go, minimizing distractions during the brewing process.
• Common mistake: Using dirty equipment. This can ruin the taste of your cold brew. Always wash your gear thoroughly.

2. Measure your coffee: For a 1:4 concentrate ratio, use 1 cup of regular ground coffee for every 4 cups of water. Adjust as desired.

• What “good” looks like: Accurate measurements lead to consistent results.
• Common mistake: Eyeballing the amount of coffee. This leads to inconsistent strength and flavor. Use a scale or measuring cups.

3. Add coffee to the vessel: Pour your measured regular ground coffee into your chosen brewing vessel.

• What “good” looks like: The coffee grounds are settled at the bottom of the vessel, ready for water.
• Common mistake: Packing the coffee down. This can create channels for water to pass through unevenly. Keep it loose.

4. Add water: Slowly pour the filtered water over the coffee grounds, ensuring all grounds are saturated.

• What “good” looks like: All coffee grounds are wet, with no dry pockets visible.
• Common mistake: Pouring water too quickly. This can cause grounds to clump and lead to uneven extraction. Pour gently in a circular motion.

5. Stir gently: Give the mixture a gentle stir to ensure all grounds are fully submerged and evenly mixed with the water.

• What “good” looks like: A consistent slurry of coffee and water, with no dry clumps.
• Common mistake: Over-stirring. This can break down the grounds too much and contribute to bitterness and sediment. Just ensure saturation.

6. Cover and steep: Cover the vessel tightly and let it steep at room temperature or in the refrigerator for 12 to 24 hours. Longer steeping times generally result in a stronger brew.

• What “good” looks like: The coffee is steeping undisturbed, allowing for slow extraction.
• Common mistake: Not covering the vessel. This can allow contaminants in or cause the coffee to absorb odors from the fridge. Use an airtight lid.

7. Prepare for filtering: Set up your filtering system. If using a paper filter, place it in a pour-over cone or drip basket over your final container. If using a sieve, place it over your container.

• What “good” looks like: Your filtering setup is secure and ready to catch the grounds.
• Common mistake: Not having a secure filter. This can lead to spills or grounds getting into your finished brew. Ensure it’s stable.

8. Begin filtering: Slowly pour the steeped coffee mixture through your filter into the clean container. You may need to do this in batches.

• What “good” looks like: The liquid is passing through the filter, leaving the grounds behind.
• Common mistake: Pouring too fast. This can overwhelm the filter, especially with regular grounds, causing it to clog or overflow. Pour slowly and deliberately.

9. Double-filter if necessary: If you notice a lot of sediment in your first filtered batch, consider pouring it through a second filter (e.g., a rinsed paper filter or a finer mesh sieve).

• What “good” looks like: A cleaner, less murky cold brew in your final container.
• Common mistake: Settling for a muddy brew. Double-filtering is an easy way to improve clarity.

10. Discard grounds: Once you’ve filtered all the liquid, carefully discard the spent coffee grounds.

• What “good” looks like: All grounds are removed from your brewed coffee.
• Common mistake: Leaving grounds in the brewing vessel. This can lead to mold if not cleaned promptly.

11. Dilute and serve: Your cold brew concentrate is ready. Dilute it with water or milk to your preferred strength, typically a 1:1 or 1:2 ratio of concentrate to liquid. Serve over ice.

• What “good” looks like: A refreshing, smooth, and flavorful beverage.
• Common mistake: Drinking the concentrate straight. It’s very strong and can be unpleasantly intense. Always dilute.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your cold brew tastes bitter, then try using slightly less coffee or steeping for a shorter time because finer grounds can over-extract more easily.
• If your cold brew has a lot of sediment, then double-filter it using a finer mesh or paper filter because regular grounds are more prone to passing through coarser filters.
• If your cold brew tastes weak, then increase the amount of coffee you use or steep for a longer duration because under-extraction leads to a thin flavor.
• If you’re in a hurry, then consider making a stronger concentrate (e.g., 1:4 ratio) and diluting it more because a higher coffee-to-water ratio can speed up perceived brew strength.
• If you notice an off-flavor, then check if your equipment is clean or if your water quality is suspect because these are common sources of unwanted tastes.
• If your paper filter is clogging quickly, then try wetting it first with a little water or switching to a coarser grind if possible because dry paper can snag finer grounds.
• If you prefer a smoother mouthfeel, then a longer steep time (closer to 24 hours) can help mellow out some of the sharper notes from regular grounds.
• If your cold brew tastes sour, then it might be under-extracted; try steeping for a few more hours or using slightly more coffee because insufficient extraction can lead to sourness.
• If you want to experiment with flavor, then try using different types of coffee beans with your regular grind because the bean itself has a significant impact on the final taste.
• If you find the cold brew too acidic, then a longer steep time can help extract more solubles that balance out the acidity.

FAQ

Can I use pre-ground coffee for cold brew?

Yes, you can use pre-ground coffee for cold brew. However, the grind size typically found in pre-ground coffee (medium) is not ideal and may result in more sediment and a less clean flavor compared to using a coarse grind.

How long should I steep regular ground coffee for cold brew?

For regular ground coffee, start with a steeping time of 12 to 18 hours at room temperature. You can extend it up to 24 hours if you prefer a stronger brew, but be mindful of potential bitterness with finer grinds.

Will my cold brew be cloudy if I use regular grounds?

It’s likely to be cloudier than cold brew made with coarse grounds. Regular grounds have more fines that can pass through filters, leading to a murkier appearance. Double-filtering can help reduce cloudiness.

How do I avoid sediment in my cold brew when using regular grounds?

The best way is to filter thoroughly. Use a fine-mesh sieve, a paper filter, or a cloth filter. Pour slowly and consider double-filtering if the first pass still has a lot of sediment.

Is it okay to use a French press for cold brew with regular grounds?

You can, but a French press filter might not be fine enough to catch all the smaller particles from regular grounds, leading to sediment. You might need to pour the French press brew through a paper filter afterward.

How much coffee do I use if I’m using regular grounds?

A good starting point is a 1:4 to 1:8 ratio of coffee to water by weight. If you’re using regular grounds and find it too strong or bitter, try increasing the water amount slightly (e.g., moving from 1:4 to 1:5).

Can I make cold brew concentrate with regular grounds?

Yes, you can make a concentrate. Use a higher ratio of coffee to water, like 1:4 or 1:5. Remember that this concentrate will need to be diluted with water or milk before drinking.
