FLO Screens for Varia FLO Dripper Varia’s FLO Dripper is compatible with a range of swappable flow screens, each of which changes the flow rate and patter during an extraction and leads to different flavor profiles in brewed coffee. We offer both new screens to allow for further experimentation with your FLO Dripper as well as replacements for the stock screens that are included by Varia. New Screens Fast 1 The Fast 1 screen is designed to achieve balance, producing blended flavors that are simultaneously complex and satisfying. It delivers a medium acidity, light body, and impressive clarity. Medium 2 The Medium 2 screen is all about balance—a blend of body, acidity, and clarity makes for juicy, well-rounded cups. Slow 2 The Slow 2 screen delivers rich, chocolatey brews with big body and mellow acidity. It’s a great option for those who appreciate a smooth, well-rounded cup. Slow 3 The Slow 3 screen slows down more than the draw-down time—optimized to maximize aftertaste and acidity, every sip will linger. Replacement Screens Medium 1 (Included with FLO Dripper) The Medium 1 screen reduces bitterness so that sweetness and acidity can shine. It gives a clean and crisp cup for a refreshing brew. Slow 1 (Included with FLO Dripper) The Slow 1 screen produces a pronounced body and a balanced profile that excels at coaxing acidity from naturally low-acid coffees, though it’s also quite versatile.
