Caraway is bringing a welcome question to automatic drip coffee: what should your water and coffee touch? Its answer centers on glass and stainless steel. For people who prefer a full pot, that is worth a closer look. For those who want one convenient cup, it raises another question: what would a better single-serve routine look like?
Here is what the Caraway coffee maker promises, how to check the materials in any brewer, and the PaperPods machine concept we are exploring for a one-cup routine.
We have not tested the Caraway coffee maker. The Caraway material descriptions below come from the manufacturer, not an independent teardown or laboratory test.
What Caraway says about its coffee maker
According to Caraway’s product page, its 10-cup drip coffee maker uses a glass reservoir and carafe, with stainless steel in the water path, showerhead and brew basket. Caraway says plastic does not touch the water or coffee.
That is a useful starting point. It is a claim about the parts your drink touches, so the next step is to ask about the complete path, including the smaller connections. A materials claim alone does not establish a health outcome or guarantee a particle-free cup.
7 questions to ask about any coffee maker’s brew path
Start where the water is stored and follow it through the heater, coffee and outlet. Cold-water contact matters too. A glass reservoir and a steel basket do not describe every component between them.
- Reservoir: What are the tank, outlet, water-level window and underside of the lid made from? Which parts touch stored water or condensation?
- Tubing: What carries water to the heater and brew head? Ask about both rigid tubing and flexible connections, including any silicone.
- Heater and pump: Which materials contact water inside these assemblies? An exterior metal casing does not identify the wetted parts.
- Valves and seals: Which gaskets, O-rings and check valves touch the water? Ask the manufacturer to identify each material.
- Showerhead and brew chamber: What touches the water as it spreads over the grounds? Check the underside as well as the visible exterior.
- Filter or pod: Does the coffee sit in paper, metal mesh or a plastic cup? Check support rings, coatings and other attached parts.
- Carafe or outlet: What does brewed coffee touch before reaching your mug, including drip-stop valves, lids and spouts?
“No plastic touches the water” describes a different scope from “the whole appliance is plastic-free.” On this site, our plastic-free category focuses on avoiding conventional petroleum-based plastics in the brew path and can include disclosed silicone seals or tubing. Silicone is a polymer, so that standard does not mean polymer-free or silicone-free.
If avoiding silicone is also a priority for you, ask for a component-by-component answer before buying. Do not infer the answer from a glass tank or a “BPA-free” label.
The question for a one-cup routine
A full-pot brewer and a single-serve brewer solve different everyday needs. There are already other approaches to one-cup brewing. Our interest is more specific: a convenient brewer designed around PaperPods, with clear information about every material the water and coffee touch.
We started with the pod. PaperPods use paper and plant-based materials without a rigid polypropylene cup. Each pod is individually nitrogen-sealed to help protect freshness before opening. Read how that packaging helps protect flavor.
Changing the pod does not change the materials inside your existing machine. PaperPods work in most K-Cup-style brewers, with Ninja and Hamilton Beach brewers excluded. Check compatibility before ordering. Used PaperPods are commercially compostable only, where accepted by a suitable facility.
The single-serve machine we are working toward
The proposed design pairs PaperPods with a glass reservoir, stainless steel brewing components and walnut details on the dry exterior. Simple controls, removable cleaning parts and serviceability are design goals.
This is a concept, with no working prototype, confirmed price or launch date. Silicone may be used in pumping tubes, seals and flexible connections. The complete water path, pod fit, durability and brew quality still need engineering validation. We are gathering interest and seeking a manufacturing partner.
If this is the kind of brewer you would like on your counter, register your interest. Your response helps us understand demand as we explore the next steps.

Frequently asked questions
Is the Caraway coffee maker plastic-free?
Caraway says no plastic touches the water or coffee. Treat that as the manufacturer’s brew-path claim, rather than a statement that every part of the appliance is plastic-free. Use the checklist above to clarify the scope.
Does the Caraway coffee maker use silicone?
A no-plastic claim does not automatically answer that question. Ask Caraway whether silicone is used in any tubing, seals or valves and which of those parts contact water or coffee.
Can PaperPods make my Keurig plastic-free?
PaperPods replace the rigid plastic pod cup. They do not replace the reservoir, tubing or other components in your brewer. Our proposed machine is a separate PlasticFreeBrew concept, not a Keurig product, and its compatibility still needs validation.
What other coffee makers should I compare?
Our Simply Good Coffee review looks at another manufacturer’s glass-and-steel approach, with silicone seals disclosed. Our BUNN VP17-1 review discusses a stainless basket option. Verify the exact configuration and complete water path before buying either. For manual options and material caveats, see our 2026 coffee gear guide.
