The Toddy system is designed to brew a concentrated, flavorful coffee with 67 percent less acidity than hot brewed coffee. The coffee concentrate is slow brewed without heat or electricity for 12-24 hours. The concentrate can then be refridgerated in the included glass carafe for up to three weeks (but it's so delicious, it never sticks around for long!) The Toddy uses regular coarse ground coffee beans, and the resulting concentrate can be combined with ice, cold water, milk, even sparkling water for a perfect summer iced coffee drink. It can also brew with hot water for a less acidic version of drip coffee. Your Toddy will include everything you need to brew except coffee. True North will include our own tips, drink recipes, and brewing instructions as well.
