The yellow Bialetti Rainbow, a modern and colorful version of the famous Italian coffee maker, pays homage to the brand's heritage while bringing a touch of vitality to your kitchen. Founded in 1933 by Alfonso Bialetti, the Bialetti brand has become an iconic symbol of Italian coffee culture. The invention of the Moka Express revolutionized the way coffee is brewed at home, allowing millions of people to enjoy rich, aromatic espresso without leaving home. The Bialetti Rainbow retains the ingenuity of the original design, with its aluminum structure, its eight characteristic sides for even heat diffusion, and its patented safety valve. This 3-cup coffee maker is perfect for those who appreciate robust, authentic coffee, prepared in a simple but effective way. The coffee prepared with the Bialetti Rainbow is the result of a simple but precise process. Simply fill the base with water, add ground coffee to the filter, then place the coffee maker over a heat source. Within minutes, boiling water rises through the coffee, releasing all the flavors and producing a full-bodied espresso. For even better coffee, use a fine grind and carefully monitor when the coffee begins to flow to avoid burning.
