Why Do Bike Water Bottles Have a Plasticky Taste and Smell?

Posted by The tiibo Team on

 

When you’re out cycling, staying hydrated is crucial, but nothing disrupts a ride quite like a sip of water that tastes more like your bottle than hydration. Many cyclists notice a plasticky taste when drinking from bike water bottles, which not only affects the flavor but can also raise concerns about the materials used in these bottles. In this blog, we'll explore why this happens and discuss the materials commonly used in plastic bike bottles.


The Culprit: Plastic Composition
Most bike water bottles are made from various types of plastics, each with its own properties and uses. The most common plastics used are:
  • Polyethylene Terephthalate (PET): Often used in disposable water bottles, PET is favored for its strength, thermo-stability, and clarity. However, PET can leach antimony, a chemical that can cause the water to have a slight metallic taste when stored at higher temperatures.

  • High-Density Polyethylene (HDPE): This material is used in many reusable water bottles. It’s recognized for its durability and strong chemical resistance. While safer in terms of leaching, HDPE can still impart a subtle plasticky flavor to water, especially when new or if the bottle heats up.

  • Low-Density Polyethylene (LDPE): Commonly used for softer, squeezable bottles, LDPE is also fairly resistant to chemical contamination but can sometimes absorb flavors and odors if not properly cleaned.

  • Polycarbonate: Previously popular due to its near-indestructibility and clear, glass-like appearance, polycarbonate fell out of favor due to health concerns linked to Bisphenol A (BPA). BPA can leach into beverages and is associated not only with a plasticky taste but also with potential health risks.

Factors Contributing to Plasticky Taste

  • Heat Exposure: Plastic bottles exposed to high temperatures, like being left in a car or in direct sunlight, can start to break down and leach chemicals faster, which contributes to the taste.

  • Bottle Age: Older plastic bottles can degrade over time. Tiny cracks and scratches can harbor bacteria and result in off-flavors.

  • Cleaning Products: The residue from strong detergents can stick to the plastic and alter the taste of the water.

  • Manufacturing Chemicals: Some plastics retain manufacturing chemicals that can leach out into the water, especially before the first few washes.

The common issue of plastic bike water bottles imparting a plasticky taste and smell was our inspiration to develop tiibo.
