Toddy is the grand daddy of cold brew coffee makers. Invented by chemist Todd Simpson in 1964, American coffee lovers have been using it to make their own cold brew coffee for half a century. It was inspired by the inventor's visit to Guatemala where he tasted a traditional cold-brewed coffee beverage, and the rest is history. The Toddy Cold Brew Coffee Maker is perfect for the avid home user. It's a simple immersion system, but its rubber stopper, sealable glass carafe and perfectly fitted filters make getting smooth consistent results very easy. It also has a pretty serious capacity, allowing you to brew up to 1.5L of concentrate at a time, and store it for up to 2 weeks in the refrigerator. If you're the type of person that would enjoy regularly drinking home-made cold brew, Toddy is an easy, tried & tested system that you can have a lot of fun with. Just use freshly ground (and freshly roasted) coffee beans and follow the in-box instructions. You can then experiment with tweaking your brewing variables.
