• Cold brew coffee making requires patience, precision, and passion.
  • Selecting the right coffee beans is crucial for a delicious cold brew.
  • Grinding the beans to a coarse texture is essential for optimal extraction.
  • Brewing cold brew coffee takes time, usually 12 to 24 hours.

Imagine the aroma of freshly ground coffee beans wafting through the air, the sound of ice cubes clinking against glass, and the sight of a rich, amber liquid slowly dripping into a carafe. This is the essence of cold brew coffee making—a craft that combines patience, precision, and passion. Today, I invite you to step behind the curtain and experience a day in the life of a cold brew coffee maker.

The Dawn of Creation: Selecting the Perfect Beans

Our journey begins with the most crucial element: the coffee beans. Not all beans are created equal—especially when it comes to cold brew. The ideal candidates are often single-origin beans with a well-balanced profile and low acidity. They must be resilient enough to withstand long brewing times without losing their unique characteristics.

To truly appreciate what goes into selecting beans for your cold brew, consider exploring our guide on brewing with different beans. It's not just about choosing a bean; it's about understanding its journey from farm to cup.

Grinding Towards Perfection: Achieving the Right Coarseness

The grind is where science meets art. For cold brew, we aim for a coarse grind—similar in texture to raw sugar—which allows for optimal extraction without over-extraction that can lead to bitterness. Achieving this requires not just any grinder, but one that offers consistency and precision.

Grinding Glory: The Art of Preparing Coffee Beans for Cold Brew

Select Your Coffee Beans
Begin your cold brew journey by choosing high-quality, whole coffee beans. Opt for beans that offer a flavor profile that resonates with the rich, smooth essence of cold brew, such as those with chocolatey, nutty, or subtle fruit notes.
Measuring coffee beans on a digital kitchen scale
Measure Your Beans
Precision is key! Use a kitchen scale to measure the right amount of coffee beans. For cold brew, a good starting ratio is 1:8 (coffee to water). So for every 1 gram of coffee, you'll need 8 grams of water. Adjust to taste after your first batch.

Choose the Right Grinder
The grind is crucial for cold brew. Use a burr grinder instead of a blade grinder to achieve a consistent, coarse grind. Burr grinders offer uniformity that is essential for the long steeping process of cold brew.

Grind to Coarse Perfection
Set your grinder to the coarse setting and grind your measured beans to the consistency of rough sea salt. This size allows for optimal extraction without over-extracting, which can lead to bitterness.
Inspecting the consistency of coarse ground coffee
Inspect the Grind
Take a moment to examine the consistency of your grind. It should be even without fine particles. If you find the grind is too fine or too uneven, adjust your grinder accordingly and try again. Consistency is the foundation of a great cold brew.
Storing ground coffee in an airtight container
Store or Brew
If you're not ready to brew just yet, store your ground coffee in an airtight container away from light and heat. When you're set, it's time to combine your grounds with cold, filtered water and let the alchemy begin!

Brewing Magic: The Long Wait

Brewing is where time becomes an ingredient. Unlike hot coffee methods that extract flavors within minutes, cold brew takes its sweet time—often 12 to 24 hours. The prolonged contact between water and coffee grounds at cool temperatures extracts a smoother and sweeter taste profile.

Classic Cold Brew Coffee

You will need:

  • coarse-ground coffee beansCoarse-ground coffee
  • glass of cold waterCold water
  • large glass jar pitcherLarge jar or pitcher
  • fine-mesh sieveFine-mesh sieve
  • cheesecloth coffee filterCheesecloth or coffee filter
  • stirring spoonStirring spoon
  • coffee storage containerStorage container for coffee


  1. Start by measuring your coffee grounds.
  2. Combine the coffee grounds and water in the jar.
  3. Stir the mixture gently.
  4. Cover and let steep for 12-24 hours.
  5. Strain the coffee through the sieve lined with cheesecloth.
  6. Transfer the cold brew to a storage container.
  7. Dilute with water or milk before serving.


The coffee-to-water ratio can be adjusted based on your strength preference. A 1:4 coffee-to-water ratio is a good starting point. For a stronger brew, use more coffee; for a lighter brew, use less. Always use filtered water for the best taste. If your cold brew is too strong, you can dilute it with more water or milk when serving.

This narrative isn't complete without considering how different equipment can influence your brew. From transforming your drip coffee maker into a makeshift cold brew device (we show you how here) to mastering your morning ritual with Keurig Cold Brew (detailed walkthrough available here), there are many paths to explore in pursuit of that perfect sip.

In this craft where every detail matters—from water temperature to bean origin—it's clear that making exceptional cold brew is both an art form and a science experiment rolled into one deliciously caffeinated package. Stay tuned as we continue our behind-the-scenes exploration...

The Alchemy of Cold Brew Extraction

As a cold brew coffee maker, the heart of your craft lies in the extraction process. This is where the magic happens, and understanding this alchemy can elevate your cold brew from good to exceptional. It's not just about steeping coffee grounds in water; it's about temperature, time, and the quality of your water. For those looking to dive deep into this topic, our guide on transforming a drip coffee maker into a cold brew machine is an invaluable resource.

Temperature plays a crucial role in extraction. Cold brew, as its name suggests, requires cold or room temperature water, which extracts flavors more slowly and produces a smoother, less acidic drink than hot brewing methods. The right balance of time—usually 12 to 24 hours—ensures that all the nuanced flavors are gently coaxed from the beans.

The Daily Grind: Selecting and Preparing Your Beans

Selecting the perfect beans for your cold brew is an art in itself. The grind size needs to be coarse enough to allow for proper water flow and extraction without over-extracting bitter compounds. Our guide on brewing with different beans offers a comprehensive look into how bean variety affects your final brew.

Crafting Your Signature Flavor Profile

The true signature of a skilled cold brew maker is their unique flavor profile. This can include experimenting with different brewing times, bean origins, or even infusions post-brewing. Imagine crafting a blend that features hints of chocolate from South American beans or fruity notes from African varieties — the possibilities are endless!

  1. Start by measuring out 1 cup of coarse ground coffee beans.
  2. Place the coffee grounds into the large jar or pitcher.
  3. Pour 4 cups of filtered water over the coffee grounds.
  4. Stir the mixture gently to ensure all grounds are wet.
  5. Cover the jar and let it steep at room temperature for 12-18 hours.
  6. After steeping, strain the coffee through a fine mesh sieve lined with cheesecloth.
  7. Transfer the strained coffee into a storage container.
  8. Refrigerate until chilled and ready to serve.


For a twist, you can add spices like cinnamon or nutmeg to the grounds before steeping for a flavored brew. Remember that cold brew is a concentrate and is often best served diluted with water or milk at a 1:1 ratio, but feel free to adjust to your taste. The cold brew can be stored in the refrigerator for up to two weeks.

Finding that perfect flavor profile often involves trial and error but fear not; every batch teaches you something new about how flavors develop over time. And remember that water quality can significantly affect taste—filtered or spring water can make all the difference in achieving a clean-tasting cold brew.

Inspiration doesn't end there; consider adding spices or extracts after brewing to introduce new dimensions to your drink. Our personal cold brew journey guide encourages exploration beyond traditional methods.
