Description
Transform Cold Brew Into Coffee Theater
The Yama 25 Cup Cold Brew Tower isn't just a brewing device—it's a showstopper. This Kyoto-style cold drip tower combines dramatic visual appeal with exceptional brewing performance, creating a hypnotic slow-drip spectacle that captivates customers while producing extraordinarily smooth, low-acid cold brew. Perfect for cafés, restaurants, specialty coffee shops, and dedicated home enthusiasts who demand the finest cold brew experience.
Why the Yama Cold Brew Tower is Different
Kyoto-Style Cold Drip vs. Immersion Brewing
Unlike traditional immersion cold brew that requires 16-24 hours of steeping, the Yama Tower uses the precision Kyoto slow-drip method to complete a full brew cycle in just 3-4 hours. Ice-cold water drips slowly through fresh coffee grounds at a controlled rate (1-1.5 seconds per drip), extracting a brighter, cleaner, more nuanced flavor profile with up to 69% less acidity than traditional hot-brewed coffee.
The result? Cold brew with remarkable clarity, natural sweetness, and complex flavor notes—without the flat, over-extracted taste common in immersion methods.
Premium Craftsmanship You Can See
Hand-Blown Borosilicate Glass
Each Yama tower is individually crafted by master glassblowers using premium borosilicate glass—the same laboratory-grade material trusted for its exceptional durability and thermal resistance. Borosilicate is non-porous, meaning it won't absorb coffee oils, flavors, or odors, ensuring every batch tastes pure and fresh.
Elegant Black Wood Frame
The straight black wood frame provides a sleek, modern aesthetic that complements any coffee bar or kitchen. Constructed from 100% solid wood with a sophisticated matte black finish, this tower makes a bold visual statement while providing stable support for the glass components.
Built to Last
- Dishwasher and microwave safe glass components
- Heat-resistant borosilicate glass construction

Adjustable Flow Rate Valve
Fine-tune your extraction with the precision flow control valve. Adjust the drip rate from 1 to 1.5 seconds per drip to customize brew strength and flavor intensity. Slower drips create bolder, more concentrated brew; faster drips produce lighter, more delicate profiles.

The elegant spiral glass chamber isn't just beautiful—it's functional. The coiled pathway evenly distributes water across coffee grounds, ensuring uniform extraction and consistent flavor in every batch.

Frequently Asked Questions
The Yama Tower completes a full 100oz brew cycle in 3-4 hours using the Kyoto slow-drip method—significantly faster than the 16-24 hours required for immersion cold brew.
Use a medium-coarse grind, similar to what you'd use for pour-over coffee. Too fine will cause over-extraction and slow dripping; too coarse will result in weak, under-extracted brew.
The Yama Tower is perfect for both! While it's widely used in cafés and restaurants, many serious home coffee enthusiasts love having this showpiece in their kitchen for entertaining and daily cold brew enjoyment.
Adjust the drip rate using the flow control valve. Slower drips (closer to 1.5 seconds) create stronger, more concentrated brew. You can also adjust coffee dose and grind size for further customization.
Yes! The hand-blown borosilicate glass components are dishwasher safe, microwave safe, and highly heat resistant. However, hand washing is recommended to preserve the pristine clarity and extend the life of your glassware.
Cold drip (Kyoto-style) uses ice water that slowly drips through coffee grounds over 3-4 hours, creating a cleaner, brighter flavor. Cold brew (immersion) steeps grounds in room-temperature water for 16-24 hours, producing a heavier, more concentrated result.
Use approximately 3-4 oz (85-115g) of medium-coarse ground coffee per 100oz water for standard strength. Adjust based on your taste preferences.
