FrankOne™ is the first One-Touch specialty coffee brewer. It uses a new brewing method called Vacuum Extraction Technology which is able to brew coffee with any grind size. You can explore different recipes and make coffee as strong as espresso using a really fine grind size, to french press with a course grind size.
