Ease of Use

Using this Amazon Basics CM1091A-UL 12 Cup Coffee Maker is straightforward. Add water to the desired level, scoop coffee grounds into the reusable filter, press the power button and brew.

Brew Performance

This Amazon Basics CM1091A-UL 12 Cup Coffee Maker brews a solid pot of coffee. The water gets hot enough to properly extract flavor from the grounds. The permanent filter allows for good filtration. The coffee comes out piping hot and fairly fast, brewing a full pot in around 7 minutes. The flavor is on par with typical drip coffee - not as rich as a French press but better than instant coffee. The keep warm plate will keep it hot for an hour or more.

Energy Efficiency and Conservation

The design of the Amazon Basics 12-Cup Coffee Maker considers not just efficiency and performance but also energy consumption. The 800-watt heating element is optimized for energy use, ensuring that it heats water quickly without excessive power consumption, reflecting the product’s commitment to energy conservation.

The Science of Coffee Extraction

Understanding how a coffee maker impacts the flavor of your brew is crucial. The Amazon Basics 12-Cup Coffee Maker employs an 800-watt heating element to quickly heat water to the ideal temperature, which is critical to prevent over-extraction and bitterness. Once heated, the water evenly percolates through the bed of coffee grounds, where the contact time of water and coffee is vital, directly determining the flavor and strength of the coffee. The design ensures that the flow rate and temperature of the water are consistent, allowing every drop of water that passes through the coffee grounds to effectively extract the aromatic compounds of the coffee.

Eco-Friendly Feature

Beyond basic functionality, a significant feature of the Amazon Basics 12-Cup Coffee Maker is its reusable filter. This not only reduces the need for disposable paper filters but also contributes to reducing waste, reflecting a commitment to environmental responsibility.


The plastic housing feels sturdy and well-constructed. The stainless steel accents should hold up well over time. As a budget coffee machine, it likely won’t have the longevity of a premium brand, but Amazon Basics products typically deliver good value. As long as it’s not abused, it should provide several years of reliable service. The 1 year limited warranty offers some peace of mind.

Maintenance and Cleaning

To ensure the longevity of the coffee maker and maintain the quality of coffee, regular cleaning of the machine is essential. Cleaning the filter and carafe not only prevents the coffee taste from being affected but also prevents the accumulation of residues and scale that could potentially damage the machine.

Ideal Usage Scenarios

With its 12-cup capacity, this Amazon Basics CM1091A-UL 12 Cup Coffee Maker is a perfect fit for family breakfasts, housemate hangouts, office breaks, and dinner parties. The keep warm function means you can brew a full pot in the morning and come back for refills throughout the day.
