I used to spend almost $7 a day on cold brew.
I did the math one summer and nearly choked on my iced coffee. That’s over $2,000 a year for something that takes 5 minutes of hands-on effort to make at home.
So I stopped. And now I make a batch every Sunday that lasts me the entire week.
This isn’t the weak, watered down stuff either. It’s smooth, low acid, and strong enough to actually wake you up. Once you make it this way, I promise you’ll look at store-bought cold brew a little differently. 😌
Let’s get into it.
What You’ll Need
Cold brew is stupid simple. You basically need coffee, water, and time.
| Ingredient | Amount |
|---|---|
| Coarse ground coffee | 1 cup |
| Cold or room temp filtered water | 4 cups |
| Optional: milk, cream, or oat milk | to taste |
| Optional: simple syrup or sweetener | to taste |
That’s it. That’s the whole ingredient list. No joke.
Tools You’ll Need
- Large mason jar or pitcher (at least 1 quart)
- Fine mesh strainer or nut milk bag
- Coffee filter (paper works fine)
- Wooden spoon for stirring
- Airtight container for storing your concentrate
Pro Tips
1. Use coarse ground coffee, not fine. Fine grounds turn your cold brew into sludge and make straining a nightmare. If you’re grinding your own beans, pulse them like you would for a French press.
2. Don’t skip the steep time. I know 12 to 24 hours feels like forever when you’re craving coffee right now. But rushing this step gives you weak, flat coffee. Trust the process.
3. Strain twice for the cleanest cup. First through a mesh strainer to catch the big grounds, then through a paper coffee filter to catch the fine sediment. This extra step makes a huge difference in texture.
4. Store it as a concentrate. Cold brew is meant to be diluted. Keep the strong stuff in the fridge and mix it with water or milk fresh each time you pour a glass.
5. Room temp water actually extracts better than ice cold. It sounds backwards, but slightly warmer water (not hot) pulls more flavor out of the grounds during the steep.
How to Make Cold Brew Coffee
- Add the coffee grounds to your jar or pitcher. Pour in the 1 cup of coarse ground coffee first.
- Pour the water over the grounds slowly. Add all 4 cups of water, making sure every ground gets wet. Give it a gentle stir with your wooden spoon.
- Cover and let it sit. Pop a lid on it or cover with plastic wrap. Let it steep at room temperature or in the fridge for 12 to 24 hours. I personally go for 18 hours, it’s my sweet spot.
- Strain through a mesh strainer. Pour the mixture through a fine mesh strainer into a new container, separating the liquid from the grounds.
- Strain again through a coffee filter. For a smoother, less gritty cup, run the liquid through a paper coffee filter a second time. This takes a few extra minutes but it’s worth it.
- Store your concentrate in the fridge. Keep it in an airtight container for up to 2 weeks.
- Serve over ice, diluted. Pour your concentrate into a glass with ice, then add water or milk at roughly a 1:1 ratio, adjusting to your taste.
Substitutions & Variations
| Original | Swap | Why It Works |
|---|---|---|
| Filtered water | Bottled spring water | Removes any tap water aftertaste |
| Regular coffee | Decaf grounds | Same process, no caffeine crash |
| Milk | Oat milk or almond milk | Dairy free and still creamy |
| Simple syrup | Maple syrup or honey | More natural sweetness |
| Mason jar | French press | Skips the straining step entirely |
Want a flavored version? Toss a cinnamon stick or a few whole vanilla beans into the jar before it steeps. Remove before straining.
Make Ahead Tips
This entire recipe is basically a make ahead recipe by design.
Make your concentrate on Sunday and you’re set through the following weekend. I like to make a double batch when I know I have a busy week coming up, that way I never run out mid-week and end up buying an overpriced iced coffee out of desperation.
Nutritional Breakdown (Estimated)
These numbers are for 8 ounces of cold brew concentrate diluted 1:1 with water, no add-ins.

Note: This is an estimate, not a lab-tested value. Actual caffeine content varies by bean type and roast.
Meal Pairings
Cold brew pairs beautifully with breakfast foods that aren’t overly sweet, since the coffee itself can carry a little bitterness.
- Buttered sourdough toast
- A simple egg and avocado plate
- Greek yogurt with fresh berries
- A slice of banana bread
Storage & Leftovers
Store your cold brew concentrate in an airtight container in the fridge for up to 2 weeks. Keep it separate from any milk or sweetener you plan to add, and only mix those in right before drinking.
Don’t freeze the concentrate. It changes the texture once thawed and honestly isn’t worth the hassle when it keeps so well in the fridge already.
FAQ
Can I use hot water to speed this up? No. Hot water pulls out different compounds and creates a more acidic, bitter flavor. That’s just iced coffee, not cold brew. The whole point of cold brew is the slow extraction.
Why does my cold brew taste weak? You’re probably drinking it at full strength instead of diluting it. Remember, what you made is a concentrate. Cut it with water or milk before drinking.
How long can I steep it? Anywhere from 12 to 24 hours works. Steeping longer than 24 hours can start to pull out bitter compounds, so I wouldn’t go past that.
Is cold brew stronger than regular coffee? Yes, the concentrate itself is significantly stronger. That’s exactly why you dilute it before drinking.
Can I make this without a strainer? A clean cheesecloth or even a clean kitchen towel works in a pinch if you don’t have a mesh strainer or nut milk bag.
Wrapping Up
Once you make cold brew this way, going back to the $7 coffee shop version is going to feel like a waste of money. It takes almost no effort, it lasts you all week, and you get to control exactly how strong or sweet it is.
Give this a try this weekend and let me know in the comments how it turned out for you. And if you have any questions about the steeping time or straining process, drop them below, I read every comment and I’m happy to help troubleshoot.
