Why cold drip

Smooth and low-acid: Slow cold extraction pulls sweetness and body while leaving harsh, bitter acids behind. The result is a clean concentrate that drinks easy black or over ice.
Reusable mesh, zero paper: The detachable stainless steel filter means no paper, no waste, and nothing to run out of. Rinse it and brew again.
You control the brew: The adjustable valve lets you dial the drip rate to taste, faster for a brighter cup, slower for a denser, syrupy concentrate.
A piece worth leaving out: Glass and clear chambers make the whole brew visible. It looks like a small piece of lab glass on the counter, and it earns its spot there.

Care & maintenance

The glass is forgiving. The filter and valve need attention.

Rinse after every brew: Warm water and dish soap for the glass and chambers. The mesh filter traps fine grounds, so soak it 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 tower is tall and the glass carafe is 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 fl oz tower, 2 oz (55 g) for the 20 fl oz. Adjust up for stronger concentrate, down for a lighter result. The brew keeps in the fridge for up to four days.

Does it really have less caffeine?

Cold extraction tends to pull fewer soluble compounds than hot water. Most cold drip drinks gentler and less acidic than an equivalent hot brew, though the exact caffeine level depends on your beans, dose, and drip rate.
