COWSAR CM3751S 14-Cup Programmable Coffee Maker: features and specs

The COWSAR CM3751S is a 14-cup drip coffee maker in stainless steel with a glass carafe and a 24-hour timer. It is built for households that brew a full pot in the morning and sometimes want a single cup later in the day, and it has a self-clean reminder to help with upkeep.

Programming and keep-warm

COWSAR describes a 24-hour reservation system, which means you set a start time up to a day ahead and the coffee is ready when you are. After brewing, the base keeps the pot warm, and the brand says you can set both the warming temperature and how long it lasts. On most drip machines, a long warming time changes the taste of the coffee as it sits, so a shorter setting is typically the better match for a pot you plan to drink within an hour or two.

Brewing options

A 1-4 cups setting lets you brew a small batch without a full pot. Drip machines generally work best when the batch size matches the setting, so this option is useful for one or two mugs. A Bold mode adjusts strength. In general, bold modes slow the brew so the water spends longer in contact with the grounds.

COWSAR says the machine uses steam-spray extraction at 176°F (80°C). That is a little below the 195-205°F range usually recommended for brewing, so it is worth understanding the temperature the brand quotes as the heating level of the spray rather than a final brew figure. The brand describes the result as a rich, American-style coffee.

Anti-drip design

The listing says brewing stops automatically when you remove the pot, so you can pour a cup before the cycle ends without drips landing on the hot plate. This is a common feature on modern machines, but it only works with the pot placed correctly, so check the manual.

Carafe, tank and filter

The pot is made of high borosilicate glass, a material that tolerates sudden temperature changes better than ordinary glass. The built-in water tank holds 2.1 L, and an external water-level line shows how much is left. The filter is detachable and washable, so you do not need paper filters, though fine grounds can pass through a permanent filter more readily than through paper.

Cleaning cycle

The machine reminds you to descale after every 90 uses. You pour a mix of white vinegar and water into the tank and press CLEAN. The cycle takes about 50 minutes and cannot be interrupted, and the indicator turns off when it finishes. Plan to run a rinse cycle with plain water afterwards, as the manual describes.

Size and power

It measures about 9.4 x 8.7 x 14.6 inches (24 x 22 x 37 cm), weighs 5.9 lb (about 2.7 kg), and is rated at 800W. The height matters in a kitchen with low cabinets, so check the clearance for filling the tank from above.

Who it suits

It suits families, small offices and anyone who likes a ready pot at wake-up time. The 1-4 cup mode helps in homes where people drink coffee at different times. COWSAR also markets it as a gift.

What to check before you buy

• Space: measure the counter width and the clearance under cabinets for the 14.6-inch height.
• Pot size: a 14-cup label generally refers to small "cups" of about 5 oz (150 ml), not large mugs.
• Filter type: confirm you are happy with a washable filter and its cleaning routine.
• Cleaning: the 50-minute descale cycle cannot be interrupted, so choose a time you will not need the machine.
• Warm-hold: decide how long you want coffee held warm.
