Brewing Cold Brew Coffee with a Standard Coffee Maker
Quick answer
- You can’t make traditional cold brew with a standard hot coffee maker.
- You can, however, make a “cold brew style” concentrate.
- This involves a longer steep time at room temperature.
- You’ll use less coffee and water than a hot brew.
- The result is a smooth, less acidic concentrate you dilute later.
- It’s a workaround, not the real deal, but it’s decent.
Who this is for
- Anyone who loves cold brew but doesn’t have a dedicated cold brew maker.
- Home brewers looking for a smoother, less acidic coffee option.
- People who want to experiment with coffee brewing methods without buying new gear.
What to check first
Brewer type and filter type
This method works best with a drip coffee maker that has a removable filter basket. If you have a permanent mesh filter, you might need to line it with a paper filter for a cleaner result. Some machines have a “brew pause” feature, which can be handy.

Water quality and temperature
Use filtered water. Tap water can add off-flavors that really come through in cold brew. For this method, room temperature water is what you want. No need to heat it up at all.
Grind size and coffee freshness
Coarse grind is key. Think sea salt. Too fine, and you’ll get sludge. Freshly roasted beans are always best. If your coffee is stale, it’ll taste even flatter cold.
Coarse grind is key. Think sea salt. For this recipe, using a good quality coarse ground coffee will make all the difference in achieving that smooth, less acidic flavor.
- Rich, sweet, and comforting, Amsterdam is the perfect drip coffee option for those who seek a deeper roast profile.
- We select the components for this coffee for their ability to stand up to a more developed roast, without ever tasting over-roasted or smoky. Instead, we pull out classic notes of chocolate, nut, and toffee.

Coffee-to-water ratio
This is where it gets different. For a concentrate, you’ll use a higher coffee-to-water ratio than hot brewing. A good starting point is around 1:4 or 1:5 (coffee to water by weight). For example, 100g of coffee to 400-500g of water.
Cleanliness/descale status
Make sure your maker is clean. Any old coffee oils will go rancid and ruin your cold brew. Run a cleaning cycle with vinegar or a descaling solution if it’s been a while.
Step-by-step (brew workflow)
1. Gather your gear. You’ll need your standard drip coffee maker, a filter (paper or mesh), coarse-ground coffee, and filtered water.
- Good looks like: Everything is clean and ready to go.
- Common mistake: Using a dirty machine. Always clean it first.
2. Place the filter. Put your chosen filter (paper or mesh) into the brew basket. If using paper, give it a quick rinse with water to remove papery taste.
- Good looks like: Filter is seated properly, no gaps.
- Common mistake: Not rinsing a paper filter. You’ll taste it.
3. Add your coffee grounds. Measure your coarse-ground coffee and add it to the filter. Aim for that 1:4 or 1:5 ratio we talked about.
- Good looks like: Even bed of grounds in the filter.
- Common mistake: Using a fine grind. This will clog the filter and make a muddy mess.
4. Add the water. Pour your room-temperature, filtered water directly into the coffee grounds. Don’t put it in the reservoir. You’re essentially steeping the grounds in the basket.
- Good looks like: All grounds are saturated.
- Common mistake: Pouring water into the reservoir. That’s for hot brewing.
5. Let it steep. This is the crucial part. Let the coffee and water sit in the basket for at least 12 hours, preferably 18-24 hours, at room temperature. Cover the basket loosely if you’re worried about dust.
- Good looks like: Patience. It needs time.
- Common mistake: Rushing the steep time. You won’t extract enough flavor.
6. Prepare for the “brew.” After steeping, place the carafe under the brew basket.
- Good looks like: Carafe is clean and in place.
- Common mistake: Forgetting to put the carafe there. Oops.
7. Run the “brew cycle.” Turn on your coffee maker. The water in the basket will slowly drip through the grounds. This is just draining the concentrate.
- Good looks like: Slow, steady drip.
- Common mistake: Thinking this is actually brewing. It’s just draining.
8. Discard the grounds. Once the dripping stops, carefully remove the brew basket and discard the spent grounds.
- Good looks like: Clean basket, no grounds left behind.
- Common mistake: Leaving grounds in the basket. They’ll get moldy.
9. Dilute and serve. You’ve made a cold brew concentrate. It will be strong. Dilute it with cold water or milk to your taste, usually 1:1 or 1:2 ratio. Add ice.
- Good looks like: A delicious, smooth iced coffee.
- Common mistake: Drinking the concentrate straight. It’s way too intense.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using a fine coffee grind | Clogged filter, muddy coffee, over-extraction, bitter taste | Use a coarse grind, like sea salt. |
| Not steeping long enough | Weak, underdeveloped flavor, sour notes | Steep for 12-24 hours at room temperature. |
| Using hot water for steeping | Extracts bitter compounds, defeats the purpose of cold brew | Use room-temperature or cold filtered water. |
| Not cleaning the coffee maker | Rancid oils, off-flavors, stale taste | Run a cleaning cycle with vinegar or descaler regularly. |
| Using tap water | Unpleasant mineral or chlorine flavors | Always use filtered water. |
| Not diluting the concentrate | Extremely strong, unpleasant coffee flavor | Dilute with water or milk (1:1 or 1:2 is a good start). |
| Storing the concentrate too long | Flavor degrades, can spoil | Use within 7-10 days, store in an airtight container in the fridge. |
| Using stale coffee beans | Flat, dull flavor, lacks complexity | Use freshly roasted beans for the best taste. |
| Incorrect coffee-to-water ratio (too low) | Weak, watery “cold brew style” drink | Start with a 1:4 or 1:5 ratio (coffee to water by weight) for concentrate. |
Decision rules (simple if/then)
- If your coffee tastes bitter, then your grind might be too fine or you steeped too long, because those factors lead to over-extraction.
- If your coffee tastes weak, then your steep time might be too short or you used too much water, because you need sufficient time and coffee grounds to extract flavor.
- If your coffee has a sour taste, then your water might be too cold during steeping or your coffee wasn’t fresh enough, because sourness often indicates under-extraction or stale beans.
- If you want a smoother, less acidic coffee, then this method can help, because the cold water extracts fewer acids than hot water.
- If you have a permanent mesh filter, then consider using a paper filter as well, because it will help catch finer particles and result in a cleaner concentrate.
- If you notice sediment in your final cup, then your grind was likely too fine or your filter wasn’t adequate, because small particles passed through.
- If you’re short on time, then this method isn’t for you, because cold brew requires a long steeping period.
- If you want to experiment with cold brew without buying new equipment, then this is a good starting point, because it uses your existing coffee maker.
- If your concentrate tastes “off” or stale, then check your water quality and the cleanliness of your brewer, because these are common culprits.
- If you’re making a large batch, then consider doubling or tripling the recipe, but be sure to maintain the same coffee-to-water ratio.
FAQ
Can I really make cold brew with a regular coffee maker?
You can make a “cold brew style” concentrate. It’s not traditional cold brew, but it’s a way to get a smoother, less acidic coffee using your existing machine.
How long does it take to make this cold brew style concentrate?
The steeping process takes a long time, typically 12 to 24 hours at room temperature. The actual “brewing” (draining) is quick.
What kind of coffee grounds should I use?
You need a coarse grind, similar to sea salt. A finer grind will clog your filter and make a muddy, bitter drink.
Do I use the water reservoir on my coffee maker?
No, you pour the water directly over the coffee grounds in the filter basket. The machine just acts as a drip mechanism to drain the steeped concentrate.
How strong is this concentrate?
It’s very strong. You’ll need to dilute it with cold water or milk, usually in a 1:1 or 1:2 ratio, before drinking.
How long does the concentrate last?
Store it in an airtight container in the refrigerator and use it within 7 to 10 days. The flavor will start to degrade after that.
What’s the difference between this and real cold brew?
Traditional cold brew is steeped in cold water for 12-24 hours and then filtered. This method uses your coffee maker to drain a concentrate that has been steeped in the filter basket. The extraction process is slightly different.
