Cold brew has quietly taken over the coffee world — and for good reason. If you've ever sipped a glass of smooth, chocolatey cold brew on a hot afternoon and thought, I wish I could make this at home, you're in the right place. The good news? It's easier than you think, and the results are absolutely worth it.
This guide walks you through everything you need to know — from picking the right beans to nailing your steep time — so you can make cold brew coffee at home that rivals anything from a café.
Why Cold Brew Has Become So Popular
Cold brew isn't just a trend. It's a fundamentally different way to experience coffee, and once people try it, they rarely go back. The slow, cold extraction process pulls out the smooth, sweet, and chocolatey notes in coffee while leaving behind much of the acidity and bitterness that can make hot coffee hard on the stomach.
It's also incredibly convenient. Make a big batch on Sunday, and you've got coffee ready to go all week. No brewing every morning, no waiting for it to cool down — just pour and enjoy.
What Makes Cold Brew Different from Iced Coffee?
A lot of people use these terms interchangeably, but they're actually quite different drinks. Here's a quick breakdown:
| Feature | Cold Brew | Iced Coffee |
|---|---|---|
| Brewing method | Cold water, long steep (12–24 hrs) | Hot brewed, then poured over ice |
| Acidity | Low — smooth and mellow | Higher — can taste sharp or sour |
| Bitterness | Minimal | More pronounced |
| Caffeine | Higher (concentrate) | Similar to regular coffee |
| Shelf life | Up to 2 weeks in the fridge | Best consumed immediately |
| Flavor profile | Rich, chocolatey, sweet | Bright, acidic, familiar |
The bottom line: cold brew is smoother, less acidic, and more forgiving. It's a great option for people who love coffee but find hot-brewed coffee too harsh.
The Best Coffee Beans for Cold Brew
Not all coffee beans are created equal when it comes to cold brew. You want beans that shine when their flavors are extracted slowly and without heat. Generally, medium to dark roasts work beautifully — they tend to have deeper, richer flavor profiles that translate well into a cold brew concentrate.
Look for tasting notes like chocolate, caramel, nuts, and dark fruit. These flavors come through especially well in cold brew. Light roasts can work too, but they often produce a thinner, more tea-like result that some people find underwhelming.
Freshness matters more than most people realize. Freshly roasted beans — ideally used within 2–4 weeks of the roast date — will give you a noticeably more vibrant and flavorful cold brew than stale grocery store coffee.
Evans Oro Negro Coffees That Excel in Cold Brew
If you're looking for freshly roasted, small-batch beans that are perfect for cold brew, Evans Oro Negro has you covered. Here are the top picks:
- Sumatra Coffee — Bold, earthy, and full-bodied with low acidity. This one was practically made for cold brew. Expect deep, syrupy notes that hold up beautifully over ice.
- Costa Rica Coffee — Bright but balanced, with a natural sweetness and clean finish. A great choice if you like your cold brew a little lighter and more nuanced.
- Guatemala Coffee — Rich chocolate and brown sugar notes make this a crowd-pleaser. It produces a smooth, well-rounded cold brew that's hard not to love.
- Max Café Blend — A carefully crafted blend designed for consistency and depth. If you want a reliable, delicious cold brew every single time, this is your go-to.
- Chocolate Hazelnut Coffee — For a sweeter twist, this flavored option adds a dessert-like quality to your cold brew. Try it with oat milk for something truly special.
Choosing the Right Grind Size
Grind size is one of the most important variables in cold brew, and it's also one of the most commonly misunderstood. You want a coarse grind — think the texture of raw sugar or coarse sea salt. This is much coarser than what you'd use for drip coffee or espresso.
Why coarse? Because cold brew steeps for a long time. If you use a fine grind, you'll over-extract the coffee and end up with a bitter, muddy mess that's hard to strain. A coarse grind extracts slowly and evenly, giving you that signature smooth flavor.
If you have a burr grinder at home, set it to the coarsest setting. If you're buying pre-ground, look for a "cold brew" or "French press" grind.
Coffee-to-Water Ratio for Balanced Flavor
The standard ratio for cold brew concentrate is 1:4 — one part coffee to four parts water by weight. So if you're using 100 grams of coffee, you'd add 400 grams (about 400ml) of cold, filtered water.
This produces a concentrate that you'll dilute before drinking — usually 1:1 with water or milk. If you prefer ready-to-drink cold brew (not a concentrate), use a 1:8 ratio instead.
Don't stress too much about being exact. Cold brew is forgiving. Start with the 1:4 ratio, taste it after diluting, and adjust from there based on your preference.
Step-by-Step Cold Brew Recipe
Here's everything you need and exactly how to do it.
What You'll Need
- 100g coarsely ground coffee (try Evans Oro Negro Guatemala or Max Café Blend)
- 400ml cold, filtered water
- A large jar or pitcher
- A fine mesh strainer, cheesecloth, or a dedicated cold brew maker
Instructions
- Grind your coffee coarsely. Aim for a texture similar to raw sugar. Fresh-ground beans will give you the best flavor.
- Combine coffee and water. Add the ground coffee to your jar, then pour in the cold water. Stir gently to make sure all the grounds are saturated.
- Cover and refrigerate. Put a lid on the jar or cover it with plastic wrap. Place it in the fridge.
- Steep for 12–24 hours. The sweet spot for most people is around 16–18 hours. Longer steeps produce a stronger, more intense concentrate.
- Strain the coffee. Pour the mixture through a fine mesh strainer lined with cheesecloth (or a coffee filter) into a clean jar. This removes all the grounds and any fine particles.
- Store and enjoy. Your cold brew concentrate is ready. Keep it in the fridge for up to two weeks.
How Long to Steep for the Best Results
Steep time is where a lot of people experiment, and that's totally fine. Here's a general guide:
- 12 hours: Lighter, more delicate flavor. Good for light roasts or if you prefer a milder cup.
- 16–18 hours: The sweet spot. Rich, smooth, and well-balanced.
- 24 hours: Bold and intense. Great for concentrate lovers or those who dilute heavily.
Avoid going beyond 24 hours — you risk over-extraction, which can make your cold brew taste bitter and harsh, defeating the whole purpose.
How to Strain and Store Cold Brew
Straining is a step people often rush, and it shows in the final cup. Take your time here. A double-strain — first through a mesh strainer, then through a coffee filter or cheesecloth — gives you the cleanest, clearest cold brew with no gritty sediment.
Once strained, store your cold brew in a sealed glass jar or pitcher in the refrigerator. It'll stay fresh and flavorful for up to two weeks, though honestly, it rarely lasts that long.
Common Mistakes That Make Cold Brew Taste Weak or Bitter
Even with a simple process, a few missteps can ruin a batch. Here's what to watch out for:
- Grind too fine: This is the #1 mistake. Fine grounds over-extract and make your cold brew bitter and difficult to strain.
- Using stale beans: Old coffee produces flat, lifeless cold brew. Always check the roast date and use beans within a few weeks of roasting.
- Steeping at room temperature: While some people do this, room-temperature steeping can encourage bacterial growth and often produces a harsher flavor. Stick to the fridge.
- Not using filtered water: Tap water with heavy chlorine or mineral content can negatively affect the flavor. Filtered water makes a real difference.
- Skipping the dilution step: Cold brew concentrate is strong. Drinking it straight can be overwhelming. Always dilute before serving.
Ways to Serve Cold Brew
One of the best things about cold brew is how versatile it is. Here are some of the most popular ways to enjoy it:
- Black over ice: The purist's choice. Just dilute your concentrate 1:1 with cold water and pour over ice. Simple and delicious.
- With milk or cream: Dilute with whole milk, oat milk, or heavy cream instead of water for a richer, creamier drink.
- Sweetened: Add a splash of simple syrup, vanilla syrup, or even a drizzle of honey. The low acidity of cold brew pairs beautifully with sweeteners.
- Cold brew latte: Mix your concentrate with steamed or frothed milk for a café-style experience at home.
- Flavored cold brew: Try Evans Oro Negro's Chocolate Hazelnut Coffee as your base for a naturally flavored cold brew that tastes like dessert in a glass.
- Cold brew tonic: Pour cold brew concentrate over tonic water with a slice of orange. Surprisingly refreshing and a little fancy.
Frequently Asked Questions
What is the best coffee for cold brew?
Medium to dark roast coffees with chocolatey, nutty, or caramel flavor notes work best. Evans Oro Negro's Sumatra, Guatemala, and Max Café Blend are excellent choices. Freshness is key — always use beans roasted within the past 2–4 weeks.
How coarse should coffee be for cold brew?
Very coarse — similar to raw sugar or coarse sea salt. This is much coarser than drip coffee. A coarse grind prevents over-extraction and makes straining much easier.
How long should cold brew steep?
Between 12 and 24 hours in the refrigerator. The sweet spot for most people is 16–18 hours, which produces a rich, smooth concentrate without bitterness.
Can you use regular ground coffee for cold brew?
Technically yes, but it's not ideal. Pre-ground coffee is usually too fine for cold brew, which leads to over-extraction and a bitter, muddy result. If you must use pre-ground, look for a "French press" or "cold brew" grind.
Does cold brew have more caffeine?
Yes, cold brew concentrate typically has more caffeine than a regular cup of hot coffee. However, because you dilute it before drinking, the caffeine in your final cup is roughly comparable — or slightly higher, depending on your dilution ratio.
How long does homemade cold brew last?
Stored in a sealed container in the refrigerator, homemade cold brew concentrate stays fresh for up to two weeks. For best flavor, try to consume it within the first week.
