Glass tower · Adjustable valve · 20 or 27 oz · Low-acid cold brew

Cold water drips through ice, then through coffee, then into a carafe. Hours, not minutes. The Slow Drip Tower turns the brew into a small piece of furniture, glass column, metal mesh, a drop every few seconds.

The Slow Cold Drip Tower is a glass cold brew tower with an adjustable drip valve, fine mesh filter, and wood serving tray. Two sizes: 20 oz (about 20 oz) and 27 oz (about 27 oz).

A drop at a time.

Care & maintenance

Glass is forgiving. The filter and valve need attention.

Rinse after every brew: Warm water and dish soap for the glass and tray. The mesh filter traps fine grounds, soak it for a few minutes, then scrub gently with a soft brush.
Valve maintenance: Disassemble the valve every few brews to check for coffee buildup. A clogged valve throws off the drip rate and ruins the extraction.
Dry fully: The valve, lid, and filter trap moisture. Leave the tower disassembled to air-dry between brews to avoid mildew.
Store carefully: The glass is tall and fragile. Stack it in a cabinet corner or leave it assembled on the counter, it looks good enough to stay out.

Frequently asked

What is the difference between cold brew and cold drip?

Cold brew is immersion, grounds soaking in cold water for twelve to twenty-four hours. Cold drip is percolation, water dripping through grounds one drop at a time over four to eight hours.

How do I set the drip rate?

Fill the top chamber with ice and water, place the grounds in the filter bed, then adjust the valve until you see roughly seven drops per ten seconds. Too fast and the brew turns thin and sour. Too slow and it stalls.

What grind do I use?

Medium to medium-coarse, like pour-over or drip. Fine grinds clog the filter and stall the drip. Coarse grinds let the water pass too quickly and under-extract.

How much coffee do I use?

Start with a 1:10 ratio, roughly 2.5 oz (70 g) of coffee for the 27 oz tower, 2 oz (55 g) for the 20 oz. Adjust up for stronger concentrate, down for a lighter result. The brew stores in the fridge for up to four days.

Does it really have less caffeine?

Yes, cold extraction pulls fewer soluble compounds than hot water, including caffeine. Expect about forty to sixty percent less than an equivalent hot brew.
