Coffee makers constructed primarily of metal, glass, and ceramic components represent a niche market focused on flavor purity and environmental consciousness. These machines often feature stainless steel boilers, portafilters, and group heads, with glass carafes or cups. They minimize or eliminate plastic parts that might interact with hot water or steam, potentially affecting the taste of the espresso.
The reduction or elimination of plastic components in espresso machines offers several potential advantages. From a flavor perspective, it addresses concerns about plastic off-gassing or leaching, ensuring a cleaner taste profile. Environmentally, these machines contribute to reducing plastic waste and promote the use of more durable, recyclable materials. This approach aligns with the increasing consumer demand for sustainable products and a growing awareness of the health and environmental impacts of plastics. Historically, early espresso machines were constructed primarily from metal, so this trend can also be seen as a return to more traditional manufacturing practices.
