Auto-Easy Siphon 3/8 Inch — Automatic Racking Siphon for Homebrewing

The 3/8-inch Auto-Siphon is an essential racking and transfer tool for homebrewers who want to move beer, wine, cider, or mead from one vessel to another cleanly, quickly, and without the undignified ritual of mouth-siphoning. A single pump stroke is all it takes to prime the siphon and start a steady, reliable flow — no sucking, no splashing, no oxygen pickup, and no risk of contaminating your carefully fermented batch with whatever else happens to be in your mouth.

What makes the auto-siphon the go-to racking tool for homebrewers at every level is its combination of simplicity and effectiveness. The pump mechanism creates suction in a single downward stroke, drawing liquid up through the inner racking tube and starting a self-sustaining siphon flow that continues without further intervention until the vessel is empty or the flow is stopped. The 3/8-inch inner diameter delivers a steady, controlled flow rate that is fast enough to rack a full fermenter without standing over it indefinitely, yet controlled enough to rack gently without disturbing the yeast cake or stirring up sediment settled at the base of the vessel. The sealed pump body keeps air out of the liquid path during priming — a critical detail that protects hop aroma, carbonation, and freshness from oxygen exposure at the most vulnerable point of the transfer.

Paired with a length of food-grade tubing and a bottling wand or receiving vessel, the auto-siphon handles racking to secondary, transferring to a keg, and filling bottles with equal ease — making it one of the highest-value tools in the homebrew equipment arsenal relative to its cost.
