Yama Glass Cold Brew Maker

Because it uses a slow-drip method, the brewing time is generally between 3 to 5 hours depending on your desired drip rate. The adjustable valve allows you to control the speed, which directly impacts the strength and extraction time of your concentrate.

Yes, it uses a round paper filter at the top of the coffee bed to ensure even water distribution. While the system includes a permanent mesh filter for the grounds, the paper filter is essential for maintaining a clean, sediment-free cup.

The tower is made of high-quality borosilicate glass, which is durable and heat-resistant, but it should be handled with care like any fine glassware. The components are modular, making it relatively straightforward to disassemble and hand-wash with mild soap and a soft brush.

No, this system is specifically engineered for cold extraction. The slow-drip process is designed to pull out delicate flavors without heat, resulting in a low-acid concentrate that is best served over ice or diluted with hot water after brewing.

The tower stands 24 inches tall, so you will need to ensure you have adequate vertical clearance under your cabinets. The footprint is relatively compact, but its height makes it a prominent visual piece, so it is best placed in an area where you have room to operate the drip valve comfortably.

You should use a medium-coarse grind, similar to what you would use for a French press. A grind that is too fine can clog the filter and slow the drip rate to a halt, while a grind that is too coarse may result in a weak, under-extracted flavor.
