Tumblers & Toxins: What You Need to Know
For years, stainless steel tumblers have been the go-to choice for keeping drinks cold and hot, with major brands like Stanley, Yeti, BrüMate, and Hydro Flask leading the market. But new concerns are emerging about what happens when your beverage sits inside these tumblers—and whether metals are leaching into your drink without you even realizing it.
Are You Drinking More Than Just Water?
Hydration is a daily priority, but what you drink from matters just as much as what you drink. Recent studies have raised concerns about metal leaching, a process where trace amounts of nickel, chromium, and iron can dissolve into beverages over time—especially with hot liquids, acidic drinks like lemon water, or prolonged use.
Many consumers have reported a metallic aftertaste in their coffee or tea, leading to questions about whether stainless steel tumblers are as safe as they seem. Some have even experienced digestive discomfort or skin irritation linked to trace metal exposure.
Why It Happens
Stainless steel is widely used for its durability and insulation properties, but it isn't completely inert. When exposed to high temperatures or acidic liquids, microscopic amounts of metal can break down and enter your drink. Over time, this may alter the taste of your beverage and potentially introduce unwanted metals into your system.
What Are the Safer Alternatives?
As awareness grows, more consumers are turning to ceramic-lined tumblers, which act as a protective barrier between your drink and the metal. Unlike standard stainless steel, ceramic-lined options:
✔ Prevent metal leaching for a cleaner, safer drink
✔ Eliminate the metallic aftertaste found in many tumblers
✔ Maintain the natural flavor of your beverage
✔ Offer the same insulation benefits without compromising purity
Why More People Are Switching to Yogi
Liberty Lake, WA-based Yogi is at the forefront of this shift, designing every tumbler with a ceramic-lined interior to ensure that nothing interferes with the taste or safety of your drink. Unlike other brands that offer ceramic as a specialty feature, Yogi has built its entire lineup around it—because we believe in a better way to drink.
If you're rethinking your tumbler, now is the time to make the switch.
