Introduction – Don't think of Better-Bottle carboys as plastic – think of them as flexible glass, because they are made from a special, scientifically tested, type of polyethylene terephthalate (PET), which does not have the disadvantages that make other plastics unacceptable for making wine or brewing beer.
Flexible Glass – Unbreakable • Negligible oxygen permeability • Meets FDA requirements with Kosher statement • No taste or odor • Clear and colorless • Extremely stain resistant • Smooth, non-porous, non-absorbing, hydrophobic surface.
Designed for Convenience – Extremely light weight and easy to handle – only ~1.5 lbs [~0.68 Kg] empty
• Inexpensive to ship – extra packaging and insurance are unnecessary
• Wide, uniform (injection molded) neck – filling is much more convenient and closures fit more reliably
• Easily cleaned (flavors rinse away quickly) and sanitized
• Easy to store, because they are light weight and unbreakable.
