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
The Better-Bottle Racking Adapter couples the High-Flow valve to any ported Better-Bottle carboy, and the combination makes professional racking and bottling quick and easy Operation The Racking Adapter uses a Teflon-encapsulated Viton O-ring to make an hydrophobic seal against the inside wall of a Better-Bottle carboy, eliminating crevices that could trap contamination. This very special O-ring also makes it possible to rotate the body of the Racking Adapter easily, without lubrication. Racking simply requires rotating the Adapter so the tip of its intake stem is just above the sediment layer, opening the High-Flow valve, and letting gravity go to work – there is no need for siphons or pumps. The external pointer makes it possible to adjust the position of the stem even if the stem cannot be seen through a dark wine or beer.
