The Better-Bottle High-Flow Valve and Racking Adapters for Carboys make up the first valve system that addresses the specialized needs of home winemakers and home brewers. Now, it is possible to rack and bottle professionally without siphons or pumps. The components are made of an incredibly tough, proprietary PET that does not stain or impart flavors and is easily cleaned and sanitized.
Better-Bottle Carboy Racking Adapters couple SimpleFlo valves to any ported Better-Bottle carboy, and the combination makes professional racking and bottling quick and easy
The Carboy Racking Adapter is especially popular with winemakers and brewers who ferment on shelves, because carboys can be racked without having to move them to a surface with head room for racking canes.
Note: SimpleFlo Valves are not included as part of Adapters – order them separately.
