A racking cane is simply a hard plastic tube used to siphon wine from one container to another. Despite their simplicity they can be a bit tricky to use.
The most difficult part of using this device is getting the flow of wine going. While you could suck on the end of the tube like a straw to get the siphon started this is hardly a sanitary way to make wine.
I’ll show you the best way I’ve found to use the racking cane. It takes a little practice but once you get the hang of it it’s really easy.
