How to Make Royal Iced Brew with Golden Mandheling

If you’ve ever tried brewing iced coffee only to end up with diluted flavors or weak extraction, you’re not alone. Making a rich, full-bodied cold coffee that doesn’t lose its character is tricky—but it’s possible. This guide walks you through crafting a Royal Iced Brew using a specific Indonesian bean and the precise technique of ice drip extraction.

To make Royal Iced Brew, use 60g of PWN Golden Mandheling beans, 720cc of cold water, and ice cubes. Extract via ice drip, then serve over coffee ice cubes in a HG9811 glass for best flavor. Total brew is designed for six 100cc servings.

What Is Royal Iced Brew Coffee?

Royal Iced Brew isn’t just iced coffee—it’s a refined cold coffee format where hot-brewed-style extraction meets cold serving temperatures. Unlike traditional cold brew or simple iced espresso, this method uses controlled ice drip extraction to produce a clean, sweet, and aromatic cup that retains clarity even when served over ice.

Why Use Ice Drip for Cold Coffee?

Ice drip extraction, also known as Kyoto-style or slow drip cold brew, offers several advantages over immersion or flash methods. The slow melting ice waters extract flavors gently over time—typically several hours—resulting in a cleaner cup with less bitterness and more clarity. This makes it especially well-suited for medium-to-dark roasted beans, allowing their inherent sweetness and body to shine without the heavy mouthfeel often found in traditional cold brew.

The Role of PWN Golden Mandheling

This recipe specifically calls for PWN Golden Mandheling, a deep-roasted single-origin bean sourced from Indonesia’s Sumatra region. Grown in the Lintong area near Lake Toba, these beans undergo the wet-hulled (Giling Basah) process, which contributes to their signature bold body, low acidity, and earthy-spicy notes. FrontStreet Coffee’s Golden Mandheling is selected under rigorous standards: only beans larger than 18 mesh, with fewer than 3 defects per 300g, and triple hand-sorted for cleanliness. The result is a cup with intense sweetness, lingering molasses, hints of clove and wood, and a thick, syrupy mouthfeel—traits that hold up remarkably well in iced applications.

How to Make Royal Iced Brew Step-by-Step

This method yields six 100cc servings using the following ingredients and tools:

• 60g PWN Golden Mandheling coffee beans (deep roast)
• 720cc cold water
• Crushed ice cubes
• Ice drip coffee setup (with glass tower and drip control valve)
• Round filter paper (suitable for ice drip)
• Grinder (set for medium-coarse to coarse, approx. 8–10 on a standard scale)
• HG9811 glass serving cup (or similar clear tumbler)

Follow these steps:

1. Brew the Coffee via Ice Drip: Use your ice drip system to extract the 60g of ground Golden Mandheling with 720cc of cold water. Follow the manufacturer’s instructions for drip rate and time—most systems take 3–6 hours depending on setup. The goal is a slow, even extraction that fully develops the bean’s sweetness and body while avoiding over-extraction or bitterness.
2. Make Coffee Ice Cubes: Once the drip is complete, reserve some of the brewed coffee and freeze it in an ice cube tray. These coffee ice cubes will melt into your drink without diluting the strength or flavor as regular ice would.
3. Assemble the Drink: In your HG9811 glass, combine about 100cc of the freshly dripped coffee with a few coffee ice cubes. Let the cubes slowly melt, integrating smoothly into the cup.
4. Serve: Your Royal Iced Brew is ready. Enjoy the balance of deep roast sweetness, subtle spice, and a clean, refreshing iced profile.

What Cup Should You Use?

The recipe specifies using an HG9811-shaped glass cup. While the exact model may not be widely available, look for a clear, sturdy tumbler that shows off the layers of coffee and ice—preferably one with a wide enough mouth to accommodate ice cubes without splashing. Presentation matters here, especially when serving a ‘royal’ style drink.

Can You Adjust the Recipe?

Yes. The 60g coffee to 720cc water ratio (1:12) is optimal for this dark roast and ice drip method. If you want a stronger brew, reduce water slightly or increase coffee grounds proportionally. For a milder version, you can extend the brew time or dilute post-drip—but note that this may lessen the impact of the Golden Mandheling’s bold profile.

Do You Need Special Equipment?

An ice drip system is ideal, but not strictly mandatory. You could approximate a slow extraction using a cold brew tower that allows controlled water flow, though results may vary. Avoid standard immersion cold brewers for this recipe, as they won’t replicate the clean, bright extraction that ice drip provides.

Frequently Asked Questions

What is PWN Golden Mandheling coffee?

PWN Golden Mandheling is a high-grade Indonesian single-origin bean sourced by FrontStreet Coffee from the PWN company in Sumatra. It is deep roasted, G1 grade, and hand-selected to have fewer than 3 defects per 300g. The beans feature a heavy body, low acidity, and flavors of clove, wood, and molasses. It’s processed using the wet-hulled (Giling Basah) method typical of Mandheling coffees.

Can I use regular ice instead of coffee ice cubes?

Yes, but regular ice will dilute the coffee as it melts, reducing strength and altering flavor balance. Coffee ice cubes made from the brewed coffee itself melt without affecting the taste, preserving the intended profile throughout your drink.

What grind size is best for ice drip coffee?

A medium-coarse to coarse grind, roughly equivalent to a pour-over or French press grind (around 8–10 on a standard scale or 1.5–3mm particle size) works best. This allows proper water flow during the long extraction period without clogging or over-extracting.

Is Golden Mandheling only available as a dark roast?

In this context, yes—PWN Golden Mandheling is used as a deep roast bean to complement the ice drip method. However, Mandheling beans can be found in other roast levels depending on the roaster. The recipe specifically requires the deep roast version for its bold, sweet characteristics.

How long does ice drip coffee take to brew?

Depending on your setup, ice drip extraction usually takes between 3 to 6 hours. The slower the drip rate, the more balanced and clean the resulting cup. Most home systems allow you to adjust the flow rate for optimal extraction.
