Nispira Cold Brew Drip Tower Coffee Maker

Because this is a slow-drip extraction method, a full cycle usually takes between 3 to 5 hours depending on your desired drip rate. The slow process is intentional, as it minimizes bitterness and highlights the natural sweetness of the beans.

You will need to check the drip rate occasionally during the first hour to ensure it remains consistent, as the flow can sometimes slow down as the water level drops. Once you have dialed in the valve setting, it generally maintains a steady pace until the cycle finishes.

Yes, the tower is versatile enough to be used for cold-brewing tea or creating concentrated infusions. Just ensure you clean the glass components thoroughly between uses to prevent flavor transfer.

The tower is made from borosilicate glass, which is durable and heat-resistant, but it should still be handled with care. Cleaning is straightforward; the glass parts are removable, and a quick hand wash with warm, soapy water is all that is needed to keep it pristine.

For the best results, 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 extraction process significantly.

The tower has a capacity of 0.4 liters, which yields approximately 6 to 8 cups of coffee. Keep in mind that this produces a concentrated brew, so you may want to dilute it with water or ice depending on your preference.
