Zulay Kitchen Cold Brew Coffee Maker

When stored in the sealed glass pitcher, your cold brew concentrate will stay fresh for up to two weeks in the refrigerator, though the flavor is typically best within the first seven to ten days.

You don't need special beans, but a coarse grind is essential. Using a fine grind can result in sediment passing through the mesh filter and may make the coffee taste overly bitter or silty.

Yes, the glass pitcher is dishwasher safe, though we recommend hand-washing the stainless steel filter to ensure the fine mesh remains clear of any trapped grounds or oils over time.

This brewer is specifically designed for cold extraction, which relies on time rather than heat to pull flavor from the grounds. It is not intended for use with boiling water, as the glass is not tempered for thermal shock.

For a standard 1.5-liter batch, a good starting ratio is about 1 cup of coarse coffee grounds to 4 cups of water. You can adjust this ratio based on your preference for a stronger or milder concentrate.

The fine-mesh stainless steel filter is designed to keep the vast majority of grounds out of your coffee. If you notice sediment, it is almost always due to using a grind that is too fine rather than a failure of the filter itself.
