  "editor": "cody-wauters",
  "page": "https://amaterio.com/plastic-free/water-bottles/",
  "summary": "November 2026, short version: four bottles make the list, all Bronze. Nothing has earned Gold or Silver yet.\n\nThe first is the soulbottles swing-top out of Berlin. Glass body, porcelain stopper, steel bail and carry handle, and a seal cut from natural rubber instead of silicone. The design on the glass is ceramic ink fired into the surface at 700 degrees, so it is not a sticker and it will not peel. What we can't confirm: the glaze on the little logo on the stopper, the gold and silver print editions, and what the shipping box is made of. We've asked. A straight answer on the glaze moves it to Silver. A paper-only box would make it Gold.\n\nThe second is Klean Kanteen's brushed Insulated TKPro 16 oz: steel bottle, steel cup, steel cap, bare brushed finish. Two silicone rings seal the cap, which is the Bronze, and the painted colors are out because the powder coat is plastic. We don't know what the logo, base cap or vacuum plug are made of, and we've asked. The maker has pulled its own page and US stock is gone; a UK shop has it.\n\nThe third is Klean Kanteen's Reflect 27 oz with the bamboo cap. Steel body, bamboo cap, no paint, and one food-grade silicone seal, which is the Bronze. We can't tell yet how the bamboo is finished, what holds it to the steel, or how the logo is marked. We've asked.\n\nThe fourth is Klean Kanteen's Rise Reflect 20 oz with the bamboo cap. Double-wall steel body, bamboo cap, no paint, and one food-grade silicone seal, which is the Bronze. We don't know how the bamboo is finished, what holds it to the steel, what the base cap and logo are, and a reviewer says the cap handle can come off. We've asked.\n\nWhat didn't make it. Pura's bottle is sold as 100% plastic-free; the lid you drink from is silicone, and so are the collar and the sleeve. Primus's TrailBottle has a Tritan lid. Klean Kanteen's brushed Classic ships with a polypropylene cap. You can buy their steel cap and swap it, but then you bought a plastic cap, and we rate a bottle the way it is sold. Also out: anything powder-coated, anything with a plastic cap in use, and every bamboo lid with a plastic insert hiding under it.\n\nIn this category, plastic-free almost always means plastic-free except the silicone. We tell you which silicone, and where it sits.",
  "whyPlastic": "The body is the easy part. Stainless and glass bottles are everywhere; the plastic is in the lid, the gasket that seals it, the straw, the carry loop, the paint or powder coat on the outside, and the sleeve. A \"stainless steel\" bottle with a polypropylene cap and a silicone seal has plastic touching every sip.",
  "whatToCheck": [
    "The cap: solid steel, wood or bamboo with a steel thread, or a plastic insert?",
    "The seal: silicone (R1, counts as plastic), natural rubber, or a cork or steel-on-steel seal?",
    "Exterior finish: bare, electropolished or vitreous enamel, or a powder coat (R3, plastic)?",
    "The logo: fired ceramic or enamel, or a powder-coated print (R3, plastic) on an otherwise bare bottle?",
    "Straws, spouts, loops and sleeves: steel, cork, cotton, or the usual silicone and nylon?",
    "Packaging: paper box and paper tape, or a plastic bag and a sticker?"
  ],
  "faq": [
    {
      "q": "Is silicone plastic?",
      "a": "Silicone is a synthetic rubber built on a silicon-oxygen chain instead of a carbon chain. It is not a petroleum plastic, it takes heat well and it does not shed microplastics the way polypropylene does, and it is also not biodegradable or widely recycled. We treat it as better than plastic and not quite plastic: a small silicone seal on an otherwise plastic-free product earns Bronze; a silicone lid, spout, straw or sleeve does not qualify. We're researching silicone properly and the line may move."
    },
    {
      "q": "Which water bottle has no plastic in the lid?",
      "a": "Glass swing-tops with a porcelain or ceramic stopper and a natural-rubber seal, like the soulbottles 0.6 l, have no plastic and no silicone in the closure. Steel bottles with all-steel caps, Klean Kanteen's Stainless Loop Cap for one, still seal with a silicone gasket."
    },
    {
      "q": "Are stainless steel bottles better than plastic?",
      "a": "For the body, yes. 18/8 stainless is inert, tough and recyclable. The plastic in a steel bottle lives in the cap, the gasket, the straw, the sleeve and, on colored bottles and some brushed ones, the powder coat or the logo. Check those five parts before you trust the label."
    },
    {
      "q": "Is a glass bottle with a bamboo lid plastic-free?",
      "a": "Usually not. Most bamboo lids are a bamboo shell over a polypropylene or silicone insert, and the insert is what seals. Ask what the part touching the glass is made of."
    }
  ],
  "whyNone": "Sealed bottles used to be plastic-free by default. Glass with a cork. A ceramic swing-top with a natural-rubber ring. A steel canteen with a steel cap and a cork or leather washer. Three things changed. Silicone pushed out natural rubber as the seal of choice through the 1990s and 2000s because it doesn't take on flavors, shrugs off the dishwasher and never perishes, so even makers who stripped out every other polymer kept the silicone ring. Then the cap became the product: sport spouts, straws, flip locks and one-handed lids are molded parts, and molded means polypropylene or silicone. And color sells, so bare steel got a powder coat, which is a plastic skin. The result is a market where plastic-free means plastic-free except the parts that touch your mouth. The old constructions still work, a few small makers still build them, and the Bronze above is the closest we have verified. Know of one that goes further? Tell us at chairman@amaterio.com.",
