Is it safe to brew coffee with plastic equipment?

No — hot water is a powerful solvent that leaches chemicals from plastic parts, including endocrine disruptors. Even BPA-free plastics have tested positive for estrogenic activity. Look for brewers and accessories made entirely from stainless steel, glass, or ceramic.

What materials should I avoid in coffee and tea accessories?

Avoid plastic components that contact hot water, non-stick coatings (which can degrade and release particles with heat), aluminum (a heavy metal linked to health concerns), and low-fire ceramics. The safest materials for coffee and tea gear are stainless steel, borosilicate glass, high-fire ceramic, and medical-grade silicone.

Do coffee pods leach chemicals?

Yes. Traditional K-cups are made of plastic, and hot water passing through them increases chemical leaching. Even BPA-free pods have tested positive for estrogenic activity. The aluminum foil tops add another concern, as aluminum is a heavy metal linked to health issues. If you use a pod brewer, look for truly compostable, PFAS-free alternatives — or switch to a stainless steel pour-over or French press setup.

Coffee & Tea Accessories

Hot water is a powerful solvent — it extracts chemicals from plastic, non-stick coatings, and aluminum just as readily as it extracts flavor from your beans. Every accessory here is made from stainless steel, glass, or non-toxic ceramic, so nothing gets between you and a clean cup.

Why Your Brewing Equipment Matters

Hot water is an especially intense solvent — it extracts substances from whatever it touches far faster than cold water does. That means the materials your coffee and tea gear is made from end up in your cup. Here's what to avoid and what to use instead.

Avoid: Plastic Parts That Contact Hot Water

Plastic components in kettles, brewers, and filters can leach endocrine-disrupting chemicals into hot water. Even BPA-free plastics have tested positive for estrogenic activity. Look for brewers and accessories with no plastic in the water path.

Avoid: Non-Stick Coatings & Aluminum

Non-stick surfaces can degrade with heat and scratch over time, releasing particles into your brew. Aluminum is a heavy metal linked to a range of health concerns. Skip both.

Avoid: Disposable Paper Cups & Plastic Lids

Paper to-go cups are lined with polyethylene, and the glue at the seams partially dissolves in hot liquid. Plastic lids marked #6 or #7 likely contain BPA — and hot coffee passes right through them on the way to your mouth. Bring your own reusable mug.

Use: Stainless Steel, Glass & Ceramic

Stainless steel is rugged, easy to clean, imparts no flavor, and lasts almost forever. Borosilicate glass and most high-fire ceramics are equally safe. Medical-grade silicone seals are acceptable where flexibility is needed. Every accessory in this collection meets these standards.

How We Vet

We only carry brewing accessories made from stainless steel, borosilicate glass, ceramic, or medical-grade silicone. We avoid anything with plastic parts that contact hot water, non-stick coatings, and aluminum components.

Styrofoam cups are even worse, as they can disrupt hormones when hot liquid is added. The safest option is a reusable stainless steel or glass mug.
