Cold Drip Coffee: The Art of Slow Extraction with Bazan Beans

Cold drip coffee, also known as Dutch coffee or Kyoto-style coffee, is a mesmerizing brew method where chilled water slowly percolates through ground coffee over several hours. Unlike cold brew, which steeps grounds in water cold drip relies on gravity and time to produce a crisp, complex, and refreshing beverage.

In this definitive guide, we explore the science, technique, and flavor potential of cold drip coffee, paired perfectly with Bazan Coffee’s fermented, specialty-grade beans. With evidence and methodologies, you’ll learn how to master this sophisticated method at home or in a café.

What Is Cold Drip Coffee?

Cold drip coffee is a slow, gravity-based brewing process where cold or ice water is dripped over ground coffee at a controlled rate, usually 1 drop every 1–2 seconds, for 3 to 8 hours.

Key Features:

• Uses a cold drip tower or Kyoto-style device

• Extracts bright, nuanced flavors with low bitterness

• No immersion drip falls through coffee bed and filter

• Often served over ice or neat

“Cold drip coffee maximizes clarity while minimizing oxidation”.

Cold Drip Coffee vs Cold Brew: What’s the Difference?

“Cold drip coffee extracts faster but requires precise drip timing and grind calibration”.

How to Make Cold Drip Coffee at Home

Equipment:

• Cold drip tower or DIY setup

• Burr grinder

• Ice + filtered water

• Scale + timer

• Fresh Bazan Coffee beans

Cold Drip Coffee Ratio:

• Coffee: 30–40g

• Water: 400–500ml (some recipes go up to 1:15 ratio)

Brew Steps:

1. Grind coffee to medium (like sand)

2. Load grounds into the center chamber

3. Place paper or metal filter beneath the coffee bed

4. Fill top chamber with ice + filtered water

5. Adjust drip rate to ~1 drop/sec

6. Let it extract over 4–6 hours

7. Store concentrate in fridge (up to 5 days)

Best Grind Size for Cold Drip Coffee

• Aim for medium grind finer than cold brew, coarser than espresso

• Inconsistent grind (blade grinders) leads to uneven extraction

• Use a burr grinder to fine-tune for drip rate and flow resistance

“A properly ground coffee bed creates gentle resistance and a more even saturation layer,”

Best Beans for Cold Drip Coffee: Why Bazan Is Ideal

Cold drip enhances clarity and floral/fruity aromatics making it ideal for naturally fermented, specialty-grade beans like Bazan Coffee.

Recommended Bazan Beans:

All Bazan beans are hand-harvested, slow-fermented, and roasted in small batches, giving them stability, sweetness, and structure when brewed cold.

“High-quality Robusta can provide syrupy texture and unique fruit layers in cold drip"

How Much Caffeine in Cold Drip Coffee?

Cold drip coffee is often more concentrated than hot brews.

Approximate Caffeine:

• 100ml cold drip concentrate = 120–150mg caffeine

• Serve over ice or dilute 1:1 for balance

Cold drip is ideal for those seeking a slow-release caffeine profile with less acidity than espresso and more complexity than iced coffee.

Cold Drip Coffee FAQs

Is cold drip stronger than cold brew?

Yes, because of shorter brew time and higher concentration. However, flavor is brighter, not necessarily “heavier.”

Can I make cold drip without a tower?

Yes. Use a DIY setup: punch holes in a plastic bottle cap or use IV drip sets. It’s tricky but possible.

How long can I store cold drip?

Up to 5 days refrigerated. For best taste, consume within 72 hours.

Should I drink it straight or dilute?

It depends on preference. For a cleaner flavor, drink straight. For a smoother drink, dilute 1:1 with water or milk.
