Stagg [XF] Dripper Fellow’s first dripper offers steep walls for an even extraction and vacuum insulation for better heat retention and a hotter cup of coffee. With a built-in ratio aid, you always know the right amount of coffee to add. The ratio aid also acts as a drip cup for when you're done brewing, making clean up a snap. The Stagg [XF] brews 1-2 cups (20 ounces). If you prefer to make slightly less, check out the Stagg [X].  Stagg Glass Carafe Hand blown with a beautiful, modern design, the Stagg Double Wall Glass Carafe pairs perfectly with the Stagg Pour Over Dripper.

With small markers on the side of the carafe, the Ratio Aid helps perfect your pour-over technique. The first dot lets you know when you’ve reached one serving (300 ml); the second dot for two (600 ml). Stagg [XF] Paper Filters Pack of 30 flat-bottom filters.
