Did you know that the Piston Coffee Maker is a French invention, named "Ground Coffee Presser, Tea, and Infusion?" That's why this coffee maker has been called "French-press" in the United States for many years. Good to know ! If we can advise you, choose a pure arabica coffee, preferably a specialty coffee from our small producers, or an single origin. Your grind should be coarse so that your filter can not let the bean through. So, your coffee liquor will be perfect for tasting. Choose your coffee here!
