FAQ

Coffee & Bakeware — FAQ

What is a flex brew coffee maker?

A flex brew coffee maker is a versatile machine designed to brew using both single-serve pods and ground coffee. This allows users to enjoy the convenience of pods or the cost-effectiveness of bulk grounds.

Can I replace just the carafe on my coffee maker?

Yes, many models offer compatible replacement carafes. Always check the model number to ensure the replacement pot fits your specific unit.

Are these machines difficult to clean?

Most modern brewers feature removable water reservoirs and dishwasher-safe parts. Regular descaling is recommended to keep your machine running smoothly.

Does the Ninja model handle iced coffee well?

Yes, the Ninja Hot & Iced XL is specifically engineered to brew at lower temperatures or with higher concentrations to prevent dilution over ice.

Is a thermal carafe better than glass?

Thermal carafes keep coffee hot without a heating plate, which prevents the burnt taste caused by prolonged heating. Glass carafes are easier to monitor but require a warming plate.

Can I use my own coffee grounds in a single-serve brewer?

Most flex brew models include a reusable filter basket specifically for grounds. This is an eco-friendly way to enjoy your favorite roast in a single-serve format.
