Why Our New tumbler Series Embraces 316L Stainless Steel for the Ultimate Pure Taste

Discover the science behind a purer sip. 

We dive deep into why we chose medical-grade 316L stainless steel over industry

-standard 304 for our new tumbler Series, 

nsuring your water, coffee, and tea taste exactly as they should.

Here at Fayren, we’re obsessed with the fundamentals. 

Introducing the tumbler Series: Built on 316L Stainless Steel.

While most stainless steel water bottle on the market use 304 stainless steel (a good, general-purpose grade), 

we asked ourselves: can we make it better? 

Can we create an interior so inert and non-reactive that it faithfully preserves the delicate notes of your single-origin coffee, 

your fine green tea, or the crisp, clean taste of filtered water?

The answer is a resounding yes, and it’s made possible by 316L stainless steel.

Think of 316L as 304’s more sophisticated cousin. The key difference is the addition of Molybdenum (2-3%). 

This powerful alloying element dramatically increases the steel's resistance to corrosion, especially from chlorides and acids.

What does this mean for your daily brew?

1.No Metallic Aftertaste: 316L is exceptionally non-reactive. 

It won’t impart a subtle "tinny" or metallic flavor to your beverages, a common issue with lower-grade steels over time.

2.Resists Pitting & Staining:Ever noticed those tiny, corrosive pits inside an old vacuum water bottle? They can harbor odors and bacteria. 

The molybdenum in 316L forms a stronger passive layer, preventing this pitting and making the interior incredibly easy to clean and odor-resistant.

3.Ideal for Acidic Drinks: Love citrus-infused water, fruit smoothies, or apple cider? The mild acids in these drinks can slowly break down 304 steel. 

316L stands strong, ensuring no unwanted flavors leach into your drink and the material integrity remains intact for years.

4.More Than Just a Material: A Commitment to Your Experience

Choosing 316L wasn’t a simple cost decision; it was a philosophical one. 

We believe the vessel you drink from should disappear, leaving you with nothing but the pure, intended flavor of your beverage. 

The fayren stainless steel cofee mug Series isn’t just a container; it’s a catalyst for a better tasting experience.

Engineered for the Purist, Designed for Everyone.

The innovation continues beyond the interior.

A Leak-Proof Lid: Designed for smooth sipping and prevents coffee stains.
