The 24-hour programmable timer is also very convenient for setting a wake-up brew in advance.

Brew Type - Drip Coffee

The BLACK+DECKER CM2045B-1 12-Cup coffee maker is a traditional drip coffee machine that brews into a thermal carafe. It does not support K-cups or other single-serve pods. The machine is designed for brewing regular filtered drip coffee.

Coffee Quality - Smooth and Flavorful

The coffee produced by the BLACK+DECKER CM2045B-1 12-Cup coffee maker is smooth and flavorful, thanks to the showerhead design that evenly saturates the grounds. The brew strength selector lets you choose regular or bold flavor. The vacuum sealed thermal carafe also helps preserve the coffee’s temperature and keep it tasting fresh for hours. The coffee has a rich color with some oils visible on the surface.

Working Principle - Standard Gravity Drip

Standard gravity drip is one of the most common methods for brewing coffee. It utilizes gravity to slowly pour hot water over coffee grounds in a filter basket to extract the coffee’s aroma and flavor.

In the standard gravity drip method, hot water first flows from the reservoir into the heater, where it is heated to the optimal brewing temperature (around 195°F). Then, the heated water passes through a tube into the showerhead, evenly spraying onto the coffee grounds. The coffee grounds gradually swell and release their aroma and oils under the action of hot water, and finally flow into the coffee pot.

The BLACK+DECKER CM2045B-1 coffee maker employs the standard gravity drip method and features Vortex™ showerhead technology for even coffee extraction, resulting in a rich and bold flavor.
