Fellow Aiden Precision Coffee Maker Matte White

A: Aiden's carafe is meant to be a reliable thermal companion to your brewing routines. It's designed to keep your coffee hot for as long as possible, but providing a specific standard is a tricky endeavor that relies on multiple factors: Brew size - Aiden's carafe is large enough to accommodate 1.5 L of coffee, which means that there will naturally be more open air above smaller batches of coffee brewed, especially when brewing less than 450ml. Because of this, smaller batches will cool more quickly than larger ones. Brew temperature - Coffee brewed at higher brewing temperatures will generally retain heat longer than those brewed at lower temperatures. Brew duration - Generally, shorter brews will retain heat longer than ones with extended blooms or pulse durations

A: Thanks for your question! Aiden uses polyphenylene oxide PPO which is 100% BPA free and doesn’t leech when boiled continuously for 12 hours. We chose this material to achieve maximum thermal stability and true-to-the-degree temperature control. In addition to being super safe to use and adding functional benefits to Aiden, this material also makes the price point significantly more accessible to home coffee drinkers around the world.

A: Hi Kylee, Aiden can not be connected directly to a waterline, it can only be filled through the water reservoir. Thanks,

A: Hello! The carafe is double-walled and insulated, with a stainless steel interior lining.
