  Do Stanley and Yeti Cups Contain Nickel?

  Team Yogi @ Aug 26, 2026

  Yes — and it isn't brand-specific.
  Stainless steel contains nickel by definition. Grade 304 is typically 8–12% nickel; grade 316 runs 10–14%. That applies to essentially every stainless tumbler on the market.

  Here's how to check what yours is made of, what the research says about transfer into your drink, and why it matters more to some people than others.

  Is Your Tumbler Changing How Your Drink Tastes?

  Jeff O'Shea @ Mar 12, 2025

  A question most people never think to ask
  You choose your coffee carefully. You pick a tea you like. You add lemon to your water because you prefer it that way. Then you pour all of it into a cup made of bare metal.

  Yogi lines every tumbler with PureTaste ceramic, so your drink sits against a smooth non-porous surface instead of steel. It never touches metal. What you taste is what you put in it.

  What's Actually Touching Your Drink?

  Jeff O'Shea @ Mar 12, 2025

  Is stainless steel safe to drink from?
  Stainless steel contains nickel and chromium, and acidity, heat and contact time all affect how much transfers into your drink. Here's what the research actually shows — without the scare tactics.

  What Changes When Your Drink Never Touches Metal

  Michael Sakakeeny @ Mar 12, 2025

  The difference you notice on the second sip
  Coffee tastes like coffee. Water with lemon tastes like water with lemon. Yesterday's drink doesn't turn up in today's.

  That's what a ceramic lining does. Yogi builds it into every tumbler — not as a premium upgrade on one model, but as standard across the entire range.

  Sensitive to Nickel or Metal? What to Look for in a Tumbler

  Jeff O'Shea @ Dec 30, 2024

  A ceramic-lined option for people with metal sensitivities
  Nickel allergy is one of the most common contact sensitivities in the world, and most stainless drinkware uses alloys that contain nickel — and that steel is what your drink sits in.

  Every Yogi tumbler is lined with PureTaste ceramic to the rim. Your drink never touches metal, so people managing a metal sensitivity can see exactly what their drink is touching.

  The Ceramic-Lined Difference

  Jeff O'Shea @ Feb 08, 2024

  You should taste your drink. Not your cup.
  Most insulated tumblers put your drink in direct contact with bare stainless steel. You notice it first in coffee, then in water with lemon, then in everything.

  Yogi lines every tumbler with PureTaste ceramic, so your drink never touches metal — no metallic edge, no flavour carried over from yesterday, no compromise on how long it stays cold.
