The Ultimate Cold Brew Coffee Guide: Brew Bold, Chill Hard

Cold brew coffee isn’t just a drink—it’s a ritual of patience, precision, and reward. Brewed slow and served cold, it delivers bold flavor without the bitterness, and smoothness without compromise. Whether you’re a die-hard caffeine chaser or just looking for the perfect iced coffee for summer, this guide will walk you through the entire cold brew process—from bean to glass.

And for the record, if you're going to do it right, start with the right beans. Honorguard Coffee’s Summer Fidelis, a stunning Costa Rican single origin, is the go-to recommendation. More on that in a minute.

Why Cold Brew Hits Different

Unlike iced coffee (which is hot-brewed and then cooled), cold brew is never subjected to heat. It’s steeped slowly in cold or room temperature water for 12 to 24 hours. This method extracts flavor in a way that reduces acidity and amps up natural sweetness, giving you a smooth, rich drink that’s refreshing and easy on the stomach.

It’s less about the jolt and more about the journey.

The Right Grind: Coarse or Bust

This part’s non-negotiable: use a coarse grind. Think kosher salt or raw sugar crystal texture. Anything finer—like espresso or drip grind—will over-extract and leave you with bitter, muddy coffee that tastes like regret.

Use a burr grinder if you’ve got one, or ask your local roaster to grind for cold brew. If you're using Summer Fidelis, request a coarse grind, or grab the whole bean and grind fresh right before brewing for peak flavor.

Coffee-to-Water Ratios: Know What You’re Brewing

There are two main types of cold brew you can make: concentrate and ready-to-drink. The difference is all in the ratio of coffee to water.

Cold Brew Concentrate

• Ratio: 1 cup coffee : 4 cups water

• Highly caffeinated and intensely flavorful

• Must be diluted before drinking (with water, milk, or both)

Ready-to-Drink Cold Brew

• Ratio: 1 cup coffee : 8 cups water

• Milder, smooth, and served straight over ice—no dilution needed

If you're not sure which one you want, start with a concentrate. It gives you flexibility to mix and adjust strength on the fly.

How to Make Cold Brew at Home

You don’t need fancy gear to make great cold brew. A mason jar, French press, pitcher, or any large container will do just fine.

What You’ll Need:

• Coarsely ground coffee (like Summer Fidelis)

• Filtered water

• A large jar or container

• Cheesecloth, nut milk bag, or fine mesh strainer

• Patience

Step-by-Step Cold Brew Recipe:

1. Measure & Add Coffee:
   Add 1 cup of coarsely ground coffee to your container.

2. Add Water:
   Pour in 4 cups (for concentrate) or 8 cups (for ready-to-drink) of filtered water. Stir to ensure all grounds are fully saturated.

3. Steep:
   Cover and let it sit at room temperature for 12–18 hours, or in the fridge up to 24 hours. Longer steep = stronger brew.

4. Strain:
   Slowly pour the mixture through a cheesecloth or fine strainer into another container. Do not squeeze the grounds—it’ll release bitterness.

5. Store:
   Keep your cold brew in a sealed container in the fridge. It’ll stay fresh for up to a week.

How to Serve Cold Brew

If you brewed concentrate, dilute it 1:1 with water, milk, or a milk alternative over ice. Adjust to taste. Some prefer a 2:1 ratio for stronger kick.
If you brewed ready-to-drink, it’s good to go—just pour it over ice and enjoy.

Need a little sweetness? Make a simple syrup (1 part hot water, 1 part sugar) or experiment with flavored versions—like vanilla, cinnamon, or lavender-infused syrup.

Want a creamier experience? Add a splash of oat milk, heavy cream, coconut milk, or sweetened condensed milk for an extra layer of indulgence.

Here’s why:

• Region: Grown in the highlands of Costa Rica, where volcanic soil and balanced rainfall cultivate rich, nuanced beans.

Advanced Tips for Cold Brew Mastery

• Use filtered water. It makes a huge difference in taste and clarity.

• Grind right before brewing. Fresher grind = fresher flavor.

• Test steep times. 14–16 hours is a sweet spot for most, but try a few brews and find your personal ideal.

• Add-ins during steeping: Try steeping with cinnamon sticks, citrus peel, or even cardamom for flavor infusions.
