A ceramic-lined option for people with metal sensitivities
If you live with a metal sensitivity, you already know how many ordinary objects you have to think about. Jewellery. Watch backs. Cutlery. Belt buckles.
Drinkware is on that list too, and it's one most people don't consider until something makes them.
What metal hypersensitivity is
Metal hypersensitivity is an allergic response triggered by contact with particular metals. Nickel is by far the most common trigger, followed by cobalt and chromium — all of which appear in various alloys.
Reactions vary. Some people get mild skin irritation. Others experience dermatitis or more persistent discomfort with prolonged exposure. It affects a very large number of people, and for those it affects, it isn't a minor inconvenience.
Why stainless drinkware comes up
Nickel is added to stainless steel to improve durability and corrosion resistance. That's why it's used so widely — in cookware, cutlery, and drinkware.
Food-grade stainless steel is considered safe by regulators, and we're not suggesting otherwise. But for someone with a nickel sensitivity, the calculation is personal rather than regulatory. If you react to nickel, you'd generally rather your drink weren't sitting against a nickel-bearing alloy for eight hours a day.
What Yogi does differently
Every Yogi tumbler is lined with PureTaste ceramic — a smooth, non-porous layer bonded to a stainless steel body and running all the way to the rim, so it won't break like a ceramic mug.
Your drink never touches metal. It sits against ceramic.
✔ No exposed metal on any drinking surface. The lining sits between your drink and the alloy.
✔ No metallic taste. The same barrier that handles the material question also keeps coffee tasting like coffee.
✔ No flavour carry-over. Non-porous, so nothing soaks in between drinks.
✔ Hot, cold and acidic drinks. Coffee, tea, citrus water — all fine.
✔ Durable underneath. Double-wall vacuum stainless exterior, doing the insulating.
We're not doctors and we won't tell you what's safe for your body. If you have a diagnosed metal sensitivity, that's a conversation for your physician or dermatologist. What we can tell you is what our lining is made of and how the cup is built.
Why it's standard, not an upgrade
Some brands sell a ceramic-lined model alongside a range of unlined ones. We line everything we make, in every size and colour, because the people who need it shouldn't have to choose from a shortlist of two.
Yogi is a small, family-owned company in Liberty Lake, Washington. A meaningful number of our customers found us specifically because of this, and we hear from them often.
